As shown in the figure, the power supply 11 provides switches 121 for the first uninterruptible power supply 12 and the second uninterruptible power supply 13 respectively. , 131, power supply module 122, 132 and control module 125, 135 operation required operating voltage, and control module 125, 135 and switch 121, 131, power supply module 122, 132 microprocessor 123, 133, battery module 124 , 134 and the output voltage terminal for signal transmission.

The displays 127 , 137 are used to display the operating states of the first and second uninterruptible power supplies 12 , 13 .

请再参阅图1、图2，由于第一不断电电源供应器12及第二不断电电源供应器13需互通，因此第一不断电电源供应器12的控制模块125与第二不断电电源供应器13的控制模块135需借助其各自的外部通讯端口126与136将信号传输出去，即电源模块122、132的微处理器123、133以及电池模块124、134所输出的信号需先传送至控制模块125、135后，再经由外部通讯端口126、136传送至其它不断电电源供应器的外部通讯端口，使不断电供电系统10中的不断电电源供应器12、13能够取得彼此的运作状态信息，借助信号的传递以达到互通的目的，进而平均负担负载16所需的能量。Please refer to Fig. 1 and Fig. 2 again, since the first uninterruptible power supply 12 and the second uninterruptible power supply 13 need to communicate with each other, the control module 125 of the first uninterruptible power supply 12 and the second uninterruptible power supply supply The control module 135 of the device 13 needs to transmit the signal through its respective external communication ports 126 and 136, that is, the signals output by the microprocessors 123, 133 of the power supply modules 122, 132 and the battery modules 124, 134 need to be transmitted to the control unit first. After the modules 125, 135, the external communication ports 126, 136 are sent to the external communication ports of other uninterruptible power supplies, so that the uninterruptible power supplies 12, 13 in the uninterruptible power supply system 10 can obtain each other's operating status information , to achieve the purpose of intercommunication by means of signal transmission, and then averagely bear the energy required by the load 16 .

由于，电源模块122、132的微处理器123、133以及电池模块124、134所输出的信号需先传送至控制模块125、135后，再经由外部通讯端口126、136才能传送至其它不断电电源供应器，如此的传输路径将造成信号传输率变慢，进而拉长整个不断电供电系统10的反应时间。另外，外部通讯端口126、136的电路结构复杂，且其内部需搭配一通讯芯片1261、1361才能进行信号传输的工作，对于致力于降低生产成本，以提升产品竞争力的制造厂商而言，这将是急需改善的问题。Because the signals output by the microprocessors 123, 133 of the power supply modules 122, 132 and the battery modules 124, 134 need to be transmitted to the control modules 125, 135 first, and then can be transmitted to other uninterruptible power supplies through the external communication ports 126, 136. For the supplier, such a transmission path will cause the signal transmission rate to slow down, thereby prolonging the response time of the entire uninterruptible power supply system 10 . In addition, the circuit structure of the external communication ports 126, 136 is complicated, and a communication chip 1261, 1361 is required to carry out the signal transmission. For manufacturers who are committed to reducing production costs and improving product competitiveness, this It will be a problem that needs to be improved urgently.

由于第二不断电电源供应器23的第二切换开关231、第二电源模块232、第二微处理器233、第二电池模块234、第二控制模块235、第二显示器236以及第二信号传输线237的设计原理及所能达成的目的及功效均与第一不断电电源供应器22的第一切换开关221、第一电源模块222、第一微处理器223、第一电池模块224、第一控制模块225、第一显示器226以及第一信号传输线227相同，因此不再赘述。Due to the second switch 231 of the second uninterruptible power supply 23, the second power supply module 232, the second microprocessor 233, the second battery module 234, the second control module 235, the second display 236 and the second signal transmission line The design principle of 237 and the purpose and effect that can be achieved are all the same as the first switch 221 of the first uninterruptible power supply 22, the first power module 222, the first microprocessor 223, the first battery module 224, the first The control module 225 , the first display 226 and the first signal transmission line 227 are the same, so they will not be repeated here.

第一不断电电源供应器22的第一信号传输线227除了与第一控制模块225、第一电源模块222的第一微处理器223及第一电池模块224直接信号连接外，其另一端也直接与连接器24信号连接，至于第二不断电电源供应器23的第二信号传输线237同样除了与第二控制模块235、第二电源模块232的第二微处理器233及第二电池模块234直接信号连接外，其另一端也直接与连接器24信号连接。如此一来，通过连接器24连接第一信号传输线227与第二信号传输线237，该第一不断电电源供应器22的第一控制模块225可以直接接收到第二不断电电源供应器23的第二电源模块232及第二电池模块234所输出的数据信号，而第二不断电电源供应器23的第二控制模块235则可以直接接收第一不断电电源供应器22的第一电源模块222及第一电池模块224所输出的数据信号，使得第一不断电电源供应器22及第二不断电电源供应器23之间不需要借助外部通讯端口(如图2所示)就可以直接互通，可降低生产成本，且第一不断电电源供应器22及第二不断电电源供应器23借助第一信号传输线227与第二信号传输线237直接互相传输数据信号，信号传输率较快，进而加快整个并联式不断电供电系统20的反应时间。In addition to the first signal transmission line 227 of the first uninterruptible power supply 22 being directly connected to the first control module 225, the first microprocessor 223 of the first power module 222 and the first battery module 224, the other end is also directly connected to the first battery module 224. It is connected with the signal of the connector 24. As for the second signal transmission line 237 of the second uninterruptible power supply 23, it is also directly connected to the second microprocessor 233 of the second control module 235, the second power supply module 232 and the second battery module 234. In addition to the signal connection, the other end is also directly connected to the connector 24 for signal connection. In this way, by connecting the first signal transmission line 227 and the second signal transmission line 237 through the connector 24, the first control module 225 of the first uninterruptible power supply 22 can directly receive the first signal of the second uninterruptible power supply 23 The data signals output by the second power module 232 and the second battery module 234, and the second control module 235 of the second uninterruptible power supply 23 can directly receive the first power module 222 and the first uninterruptible power supply 22 of the first uninterruptible power supply 22. The data signal output by the first battery module 224 enables the first uninterruptible power supply 22 and the second uninterruptible power supply 23 to communicate directly without using an external communication port (as shown in FIG. 2 ). Reduce production costs, and the first uninterruptible power supply 22 and the second uninterruptible power supply 23 directly transmit data signals to each other by means of the first signal transmission line 227 and the second signal transmission line 237, and the signal transmission rate is faster, thereby speeding up the entire parallel connection The response time of the uninterruptible power supply system 20.

另外，于另一实施例中，还可利用电源传输线29连接第一不断电供电系统22与第二不断电供电系统23，以对单一或多个负载进行备用式(redundant)或容量提升模式的能量供应分配，同时使并联式不断电供电系统免用配电盒，以进一步降低成本与省去组装配电盒的麻烦。请参阅图4，其为本发明另一较佳实施例的并联式不断电供电系统的架构示意图。如图4所示，本发明的并联式不断电供电系统20的一端接收供电电源21所提供的交流电(AC)，而另一端与例如第一负载27及第二负载28电连接，用以提供第一负载27及第二负载28运作所需的能量。该并联式不断电系统20主要包含：第一不断电电源供应器22、第二不断电电源供应器23、第一信号传输线227、第二信号传输线237、连接器24以及电源传输线29。In addition, in another embodiment, the first uninterruptible power supply system 22 and the second uninterruptible power supply system 23 can also be connected by a power transmission line 29, so as to perform redundant or capacity boost mode for single or multiple loads. Energy supply and distribution, and at the same time make the parallel uninterruptible power supply system free from the distribution box, so as to further reduce the cost and save the trouble of assembling the distribution box. Please refer to FIG. 4 , which is a schematic structural diagram of a parallel uninterruptible power supply system according to another preferred embodiment of the present invention. As shown in FIG. 4, one end of the parallel uninterruptible power supply system 20 of the present invention receives the alternating current (AC) provided by the power supply 21, and the other end is electrically connected with, for example, a first load 27 and a second load 28 to provide The energy required for the operation of the first load 27 and the second load 28 . The parallel uninterruptible power supply system 20 mainly includes: a first uninterruptible power supply 22 , a second uninterruptible power supply 23 , a first signal transmission line 227 , a second signal transmission line 237 , a connector 24 and a power transmission line 29 .

如图4所示，第一不断电电源供应器22与第二不断电电源供应器23间以并联连接，其中，第一不断电电源供应器22与供电电源21及第一负载27电性连接，用以接收供电电源21所输出的交流电，并输出第一负载27运作所需的能量。第二不断电电源供应器23同样设置于供电电源21与第二负载28之间，用以接收供电电源21所输出的交流电，并输出第二负载28运作所需的能量。第一不断电电源供应器22与第二不断电电源供应器23之间借助第一信号传输线227、第二信号传输线237以及连接器24达到通讯与沟通的功能，其设计原理如前所述，于此不再赘述。另外，第一不断电电源供应器22与第二不断电电源供应器23之间并借助电源传输线29作为两者之间传递与分配电源的路径。As shown in FIG. 4 , the first uninterruptible power supply 22 and the second uninterruptible power supply 23 are connected in parallel, wherein the first uninterruptible power supply 22 is electrically connected to the power supply 21 and the first load 27 , used to receive the AC output from the power supply 21 and output the energy required for the operation of the first load 27 . The second uninterruptible power supply 23 is also disposed between the power supply 21 and the second load 28 for receiving the AC power output by the power supply 21 and outputting the energy required for the operation of the second load 28 . The first uninterruptible power supply 22 and the second uninterruptible power supply 23 achieve communication and communication functions through the first signal transmission line 227, the second signal transmission line 237 and the connector 24. The design principle is as described above. No more details here. In addition, the first uninterruptible power supply 22 and the second uninterruptible power supply 23 use the power transmission line 29 as a path for transmitting and distributing power between the two.

请参阅图5，其为图4所示实施例的并联式不断电供电系统的电路架构方框示意图。于此实施例中，第一不断电电源供应器22与第二不断电电源供应器23的内部电路架构与前述实施例大体上相同，于此不再赘述。此外，电源传输线29的一端连接于第一不断电电源供应系统22的第一切换开关221与第一电源输出端228间，而电源传输线29的另一端则连接于第二不断电电源供应系统23的第二切换开关231与第二电源输出端238间。由于为了延长不断电供电系统20内部所设置的所有不断电电源供应器22、23的生命周期，以及提高输出电源的可靠度，会借助连接于第一不断电电源供应器22及第二不断电电源供应器23之间的第一信号传输线227、第二信号传输线237以及连接器24来进行沟通，以共同负担第一负载27及第二负载28所需的能量，进而达到平衡电力的功效。待第一不断电电源供应器22及第二不断电电源供应器23之间互通结束，第一不断电电源供应器22或是第二不断电电源供应器23就会根据互通结果将其产生的部分能量，经由电源传输线29所提供的传输路径将电源传递至对方中，而作为接收端的不断电电源供应器会将其自行产生的能量以及所接收的能量传送至所连接的负载，例如：第一负载27需要的操作能量为3kva，第二负载28所需的操作能量为2kva，而第一不断电电源供应器22及第二不断电电源供应器23利用第一信号传输线227、第二信号传输线237以及连接器24的通讯路径互通的结果假若为两者平均分担第一负载27及第二负载28所需的操作能量，即第一不断电电源供应器22及第二不断电电源供应器23需个别产生(3kva+2kva)/2＝2.5kva的能量，由于第二不断电电源供应器23连接的第二负载28只需要2kva的能量，因此第二不断电电源供应器23所产生的2.5kva能量，其中2kva能量输出至第二负载28，而其中0.5kva则借助电源传输线29传递至第一不断电电源供应器22，第一不断电电源供应器22将其自行产生的2.5kva能量以及由第二不断电电源供应器23所接收来的0.5kva能量，即2.5kva+0.5kva＝3kva，一并传送至第一负载27，用以提供第一负载27运作所需的电源。Please refer to FIG. 5 , which is a schematic block diagram of the circuit structure of the parallel uninterruptible power supply system of the embodiment shown in FIG. 4 . In this embodiment, the internal circuit structures of the first uninterruptible power supply 22 and the second uninterruptible power supply 23 are substantially the same as those of the foregoing embodiments, and will not be repeated here. In addition, one end of the power transmission line 29 is connected between the first switch 221 of the first uninterruptible power supply system 22 and the first power output terminal 228, and the other end of the power transmission line 29 is connected to the second uninterruptible power supply system 23 between the second switching switch 231 and the second power output terminal 238 . Because in order to prolong the life cycle of all uninterruptible power supplies 22, 23 provided inside the uninterruptible power supply system 20, and improve the reliability of the output power, it will be connected to the first uninterruptible power supply 22 and the second uninterruptible power supply The first signal transmission line 227 , the second signal transmission line 237 and the connector 24 communicate among the power supplies 23 to share the energy required by the first load 27 and the second load 28 , thereby achieving the effect of power balance. After the intercommunication between the first uninterruptible power supply 22 and the second uninterruptible power supply 23 is completed, the first uninterruptible power supply 22 or the second uninterruptible power supply 23 will generate the data according to the intercommunication result. Part of the energy is transmitted to the other party through the transmission path provided by the power transmission line 29, and the uninterruptible power supply as the receiving end will transmit the energy generated by itself and the energy received to the connected load, for example: The operating energy required by a load 27 is 3kva, the operating energy required by the second load 28 is 2kva, and the first uninterruptible power supply 22 and the second uninterruptible power supply 23 use the first signal transmission line 227, the second signal If the result of the communication path intercommunication between the transmission line 237 and the connector 24 is that the two equally share the operating energy required by the first load 27 and the second load 28, that is, the first uninterruptible power supply 22 and the second uninterruptible power supply 23 needs to individually produce the energy of (3kva+2kva)/2=2.5kva, because the second load 28 that the second uninterruptible power supply 23 is connected only needs the energy of 2kva, so the second uninterruptible power supply 23 produces 2.5kva energy, of which 2kva energy is output to the second load 28, and 0.5kva of which is transmitted to the first uninterruptible power supply 22 through the power transmission line 29, and the first uninterruptible power supply 22 uses the 2.5kva energy generated by itself And the 0.5kva energy received by the second uninterruptible power supply 23 , that is, 2.5kva+0.5kva=3kva, is transmitted to the first load 27 to provide the power required for the operation of the first load 27 .

在本实施例中，电源传输线29为一用以传递电源能量的传输线，任何可提供足够能量的电源线(hard-wires with sufficient capacity)均为本发明所保护的范围。In this embodiment, the power transmission line 29 is a transmission line for transmitting power energy, and any hard-wires with sufficient capacity are within the protection scope of the present invention.

当然，本较佳实施例的并联式不断电供电系统20同样具有并联备用运转功能以及容量提升功能的运作模式，以下将详述其运作原理：Of course, the parallel uninterruptible power supply system 20 of this preferred embodiment also has the operation mode of the parallel standby operation function and the capacity enhancement function, and its operation principle will be described in detail below:

1.备用式(redundant)运作1. Redundant operation

备用式的不断电供电系统的运作原理为：当并联式不断电供电系统20内部有任一个不断电电源供应器22或23因例如电池老化或是其它零件故障而无法运作时，另外一个不断电电源供应器就必须马上提高其能量的供应量，通过电源传输线29传递电源能量至发生故障的不断电电源供应器端，以代替发生故障的不断电电源供应器提供负载运作所需的电源。另外，由于第一不断电电源供应器22的输出能量S3受限于其第一电源输出端228，例如插座组件的额定容量P1，同理，第二不断电电源供应器23的输出能量S4受限于其第二电源输出端229，例如插座组件的额定容量P2，因此，为了使并联式不断电供电系统20内部的第一及第二不断电电源供应器22、23具有并联备用运转功能，故输出能量S3、S4以及S3和S4的加总电压S5必须满足下列的关系式：S3≤P1、S4≤P2且S5≤(P1+P2)/2，例如：第一及第二不断电电源供应器22、23的第一与第二电源输出端228、238的额定容量P1、P2均为5kva，为了符合备用式的运作模式，输出能量S3、S4以及S3和S4的加总能量S5必须满足S3、S4≤5kva，且S5≤(5+5)/2kva的条件，举例而言，与第一不断电电源供应器22连接的第一负载27需要的操作电压为3kva，与第二不断电电源供应器23连接的第二负载28所需的操作能量为2kva，即输出能量S3为3kva，输出能量S4为2kva，且加总能量S5为2kva+3kva＝5kva。The operating principle of the standby UPS system is: when any UPS 22 or 23 in the parallel UPS system 20 fails to operate due to battery aging or failure of other parts, the other UPS will The power supply must increase its energy supply immediately, and transmit the power energy to the failed UPS end through the power transmission line 29, so as to replace the failed UPS to provide the power required for load operation. In addition, because the output energy S3 of the first uninterruptible power supply 22 is limited by its first power output terminal 228, such as the rated capacity P1 of the socket assembly, similarly, the output energy S4 of the second uninterruptible power supply 23 is limited by It is limited to its second power supply output end 229, such as the rated capacity P2 of the socket assembly. Therefore, in order to make the first and second uninterruptible power supplies 22, 23 inside the parallel uninterruptible power supply system 20 have a parallel standby operation function, Therefore, the output energy S3, S4 and the total voltage S5 of S3 and S4 must satisfy the following relationship: S3≤P1, S4≤P2 and S5≤(P1+P2)/2, for example: the first and second uninterruptible power supply The rated capacities P1 and P2 of the first and second power output terminals 228 and 238 of the suppliers 22 and 23 are both 5kva. In order to comply with the standby mode of operation, the output energies S3 and S4 and the total energy S5 of S3 and S4 must be Satisfy the conditions of S3, S4≤5kva, and S5≤(5+5)/2kva, for example, the operating voltage required by the first load 27 connected to the first uninterruptible power supply 22 is 3kva, and the second uninterruptible power supply The operating energy required by the second load 28 connected to the electric power supply 23 is 2kva, that is, the output energy S3 is 3kva, the output energy S4 is 2kva, and the total energy S5 is 2kva+3kva=5kva.

当第一不断电电源供应器22及第二不断电电源供应器23处于正常运作状态时，第一不断电电源供应器22及第二不断电电源供应器23利用第一信号传输线227、第二信号传输线237以及连接器24的通讯路径互通，且互通的结果假若为两者平均分担第一负载27及第二负载28运作所需的能量，即第一不断电电源供应器22及第二不断电电源供应器23需个别产生(3kva+2kva)/2＝2.5kva的能量，由于第二不断电电源供应器23连接的第二负载28只需要2kva的能量，因此第二不断电电源供应器23所产生的2.5kva能量，其中2kva能量输出至第二负载28，而其中0.5kva则借助电源传输线29传递至第一不断电电源供应器22，以达到平衡电力的功效，而第一不断电电源供应器22将其自行产生的2.5kva能量以及由第二不断电电源供应器23所接收来的0.5kva能量，即2.5kva+0.5kva＝3kva，一并传送至第一负载27，用以提供第一负载27运作所需的电源。When the first uninterruptible power supply 22 and the second uninterruptible power supply 23 are in the normal operation state, the first uninterruptible power supply 22 and the second uninterruptible power supply 23 use the first signal transmission line 227, the second uninterruptible power supply The communication paths of the signal transmission line 237 and the connector 24 are intercommunicated, and if the result of the intercommunication is that the two equally share the energy required for the operation of the first load 27 and the second load 28, that is, the first uninterruptible power supply 22 and the second uninterruptible power supply The power supply 23 needs to individually generate (3kva+2kva)/2=2.5kva of energy, because the second load 28 connected to the second uninterruptible power supply 23 only needs 2kva of energy, so the second uninterruptible power supply 23 generated 2.5kva energy, of which 2kva energy is output to the second load 28, and 0.5kva of which is transmitted to the first uninterruptible power supply 22 through the power transmission line 29 to achieve the effect of balancing power, while the first uninterruptible power supply The power supply 22 transmits the 2.5kva energy generated by itself and the 0.5kva energy received by the second uninterruptible power supply 23, that is, 2.5kva+0.5kva=3kva, to the first load 27 for Provide the power required for the operation of the first load 27 .

当第一不断电电源供应器22或是第二不断电电源供应器23的其中一个发生故障时，另外一个不断电电源供应器就必须马上提高其能量的供应量，通过电源传输线29传递电源能量至发生故障的不断电电源供应器端，以代替发生故障的不断电电源供应器提供负载运作所需的能量。举例而言，当第二不断电电源供应器23因为发生故障而无法运作时，第一不断电电源供应器22则需要将其能量生产量由原本的2.5kva提升到5kva，即第一负载27及第二负载28运作所需的能量要全部改由第一不断电电源供应器22来提供，而第一不断电电源供应器22所产生的5kva能量，其中3kva能量输出至与其连接的第一负载27，而其中2kva则借助电源传输线29传递至第二不断电电源供应器23，以输出至第二负载28，从而达到备用的目的。When one of the first uninterruptible power supply 22 or the second uninterruptible power supply 23 fails, the other uninterruptible power supply must immediately increase its energy supply, and transmit power energy through the power transmission line 29 To the failed uninterruptible power supply end, to replace the failed uninterruptible power supply to provide the energy required for load operation. For example, when the second uninterruptible power supply 23 fails to operate due to a failure, the first uninterruptible power supply 22 needs to increase its energy production from the original 2.5kva to 5kva, that is, the first load 27 And the energy required for the operation of the second load 28 will all be provided by the first uninterruptible power supply 22, and the 5kva energy generated by the first uninterruptible power supply 22, wherein 3kva energy is output to the first uninterruptible power supply connected to it. The load 27, and 2kva of which is transmitted to the second uninterruptible power supply 23 through the power transmission line 29, so as to output to the second load 28, so as to achieve the purpose of backup.

2.容量提升运作模式2. Capacity enhancement operation mode

在此种运作模式下，第一及第二不断电电源供应器22、23并不具有前述的并联备用运转功能，但是第一及第二不断电电源供应器22、23的输出能量S3及S4的加总能量S5最高可达到第一及第二不断电电源供应器22、23的第一与第二电源输出端228、238的额定容量P1及P2的总和，即S5≤(P1+P2)，可达到提升输出能量的功效。另外，由于第一及第二不断电电源供应器22、23的输出能量S3、S4分别受限于由其第一与第二电源输出端228、238，例如插座组件的额定容量P1、P2，因此输出能量S3、S4必须满足S3≤P1、S4≤P2，例如：第一及第二不断电电源供应器22、23的第一与第二电源输出端228、238的额定容量P1、P2均为5kva，为了符合容量提升的运作模式，输出能量S3、S4必须满足S3、S4≤5kva，且输出能量S3及S4的加总能量S5最高可达到S5≤10kva的条件。举例而言，与第一不断电电源供应器22连接的第一负载27需要的操作能量为5kva，与第二不断电电源供应器23连接的第二负载28所需的操作能量为3kva，即输出能量S3为5kva，输出能量S4为3kva，加总能量S5为5kva+3kva＝8kva。In this mode of operation, the first and second uninterruptible power supplies 22, 23 do not have the aforementioned parallel standby operation function, but the output energies S3 and S4 of the first and second uninterruptible power supplies 22, 23 The total energy S5 can reach the sum of the rated capacities P1 and P2 of the first and second power output terminals 228, 238 of the first and second uninterruptible power supplies 22, 23, that is, S5≤(P1+P2) , can achieve the effect of increasing the output energy. In addition, since the output energy S3 and S4 of the first and second uninterruptible power supplies 22 and 23 are respectively limited by their first and second power output terminals 228 and 238, such as the rated capacity P1 and P2 of the socket assembly, Therefore, the output energy S3, S4 must satisfy S3≤P1, S4≤P2, for example: the first and second power output terminals 228, 238 of the first and second uninterruptible power supply is 5kva, in order to comply with the operation mode of capacity increase, the output energy S3, S4 must meet the condition of S3, S4≤5kva, and the total energy S5 of the output energy S3 and S4 can reach the condition of S5≤10kva. For example, the operating energy required by the first load 27 connected to the first uninterruptible power supply 22 is 5kva, and the operating energy required by the second load 28 connected to the second uninterruptible power supply 23 is 3kva, namely The output energy S3 is 5kva, the output energy S4 is 3kva, and the total energy S5 is 5kva+3kva=8kva.

当第一不断电电源供应器22及第二不断电电源供应器23处于正常运作状态时，第一不断电电源供应器22及第二不断电电源供应器23将利用第一信号传输线227、第二信号传输线237以及连接器24的通讯路径互通，且当互通的结果假若为两者平均分担第一负载27及第二负载28所需的操作能量时，即第一不断电电源供应器22及第二不断电电源供应器23需个别产生(5kva+3kva)/2＝4kva的能量，由于第二不断电电源供应器23连接的第二负载28只需要3kva的能量，因此第二不断电电源供应器23所产生的4kva能量，其中3kva能量输出至第二负载28，而其中1kva则借助电源传输线29传递至第一不断电电源供应器22，第一不断电电源供应器22将其自行产生的4kva能量以及由第二不断电电源供应器23所接收来的1kva能量，即4kva+1kva＝5kva，一并传送至第一负载27，用以提供第一负载27运作所需的能量。When the first uninterruptible power supply 22 and the second uninterruptible power supply 23 are in the normal operation state, the first uninterruptible power supply 22 and the second uninterruptible power supply 23 will use the first signal transmission line 227, the second uninterruptible power supply The communication paths of the two signal transmission lines 237 and the connector 24 are interconnected, and if the result of the interconnection is that both of them equally share the operating energy required by the first load 27 and the second load 28, that is, the first uninterruptible power supply 22 and the second load 28 The second uninterruptible power supply 23 needs to individually generate (5kva+3kva)/2=4kva of energy, because the second load 28 connected to the second uninterruptible power supply 23 only needs 3kva of energy, so the second uninterruptible power supply Of the 4kva energy generated by the supplier 23, 3kva of it is output to the second load 28, and 1kva of it is transmitted to the first uninterruptible power supply 22 through the power transmission line 29, and the first uninterruptible power supply 22 generates it by itself The energy of 4kva and the energy of 1kva received by the second uninterruptible power supply 23, that is, 4kva+1kva=5kva, are transmitted to the first load 27 to provide the energy required for the operation of the first load 27.

当第一不断电电源供应器22或是第二不断电电源供应器23的其中一个发生故障时，由于在此种容量倍增的运作模式下，第一及第二不断电电源供应器22、23并不具有前述的并联备用运转功能，因此，第一负载27运作所需的能量将改由第一不断电电源供应器22的旁路229直接由供电电源21提供，第二负载28运作所需的能量将改由第二不断电电源供应器23的旁路239直接由供电电源21提供。When one of the first uninterruptible power supply 22 or the second uninterruptible power supply 23 fails, due to the operating mode of this capacity multiplication, the first and second uninterruptible power supply 22, 23 It does not have the aforementioned parallel standby operation function, therefore, the energy required for the operation of the first load 27 will be directly provided by the power supply 21 through the bypass 229 of the first uninterruptible power supply 22, and the energy required for the operation of the second load 28 The energy will be directly provided by the power supply 21 through the bypass 239 of the second uninterruptible power supply 23 .

因此，利用电源传输线29连接第一不断电供电系统22与第二不断电供电系统23，不仅可以对负载进行备用式或容量提升模式的能量供应分配，同时使并联式不断电供电系统免用配电盒，以进一步降低成本与省去组装配电盒的麻烦。Therefore, using the power transmission line 29 to connect the first UPS 22 and the second UPS 23, not only can the energy supply and distribution of the load be carried out in standby mode or capacity boost mode, but also make the parallel UPS system free from the need for distribution. Electric box to further reduce the cost and save the trouble of assembling the electric box.

另外，请参阅图6，其是本发明的并联式不断电供电系统的结构示意图。如图6所示，本发明的并联式不断电供电系统的第一不断电电源供应器22与第二不断电电源供应器23分别容置于一第一壳体3与一第二壳体4内，其中第一不断电电源供应器22与第二不断电电源供应器23的第一与第二电源模块222、232以及第一与第二电池模块224、234为可热插拔替换的模块，因此电源模块间以及电池模块间可以插拔替换，以减少维修或替换零件的成本。In addition, please refer to FIG. 6 , which is a schematic structural diagram of the parallel uninterruptible power supply system of the present invention.
