It should be noted that for the emergency cutoff electronic circuit shown in Fig. 3, also can possess in described emergency cutoff electronic circuit There are other relative electronic components, the embodiment of the present invention does not repeat to this.Explanation in need again, for arbitrary urgent pass Loom circuit, described emergency cutoff electronic circuit can also possess other circuit structures outside Fig. 3, and the embodiment of the present invention is to this not It is limited in any way.
Further, in order to improve parallel connection each emergency cutoff electronic circuit independence so that each emergency cutoff electronic circuit Do not interfere with each other, in embodiment of the present invention, at least one first emergency cutoff electronic circuit 11 described and at least one Any two emergency cutoff electronic circuit in two emergency cutoff electronic circuits 12 generally may be configured as the state being electrically isolated from each other, thus Can further up to improve Modular UPS system emergency shut down reliability effect so that in emergency episode, Modular UPS Can immediately effectively shut down, it is to avoid the expansion further of disaster.
Specifically, in embodiment of the present invention, at least one first emergency cutoff electronic circuit 11 described and Any two emergency cutoff electronic circuit at least one second emergency cutoff electronic circuit 12, can pass through will be tight for described any two The power supply of anxious shutdown electronic circuit is set to the mode that is electrically isolated from each other to realize described any two emergency cutoff electronic circuit Electric isolution.
For example, a first emergency cutoff electronic circuit 11 is included with described emergency cutoff circuit and one second promptly close As a example loom circuit 12, can pass through will the power supply of described first emergency cutoff electronic circuit 11 and described second emergency cutoff The power supply of circuit 12 is set to the mode that is electrically isolated from each other to realize described first emergency cutoff electronic circuit 11 and described the The electric isolution of two emergency cutoff electronic circuits 12, to prevent from this first going up electricity due to a road power supply, causes another road to power electricity There is the problem of the circuit devcie misoperation that residual voltage led in source.
Further, at least one first emergency cutoff electronic circuit 11 described and at least one the second emergency cutoff Any two emergency cutoff electronic circuit in electronic circuit 12, can be by respectively in the confession of described any two emergency cutoff electronic circuit The phase to realize the power supply of described any two emergency cutoff electronic circuit for the mode of electric power end setting one backward diode Mutually electrically insulate, the embodiment of the present invention is not limited in any way to this.
For example, still a first emergency cutoff electronic circuit 11 is included with described emergency cutoff circuit and one second urgent As a example shutdown electronic circuit 12, can be by respectively in the power supply end and described the of described first emergency cutoff electronic circuit 11 The power supply end of two emergency cutoff electronic circuits 12 arranges a backward diode to realize described first emergency cutoff electronic circuit 11 Being electrically isolated from each other of power supply and the power supply of described second emergency cutoff electronic circuit 12.
It should be noted that at least one first emergency cutoff electronic circuit 11 described and at least one is second urgent Any two emergency cutoff electronic circuit in shutdown electronic circuit 12, due to usual between described any two emergency cutoff electronic circuit Also can possess and have other signals that are mutually related（These signals that are mutually related are likely to affect this two emergency cutoff electricity Signal between the power supply on road connects）, therefore, merely with reverse the two of this two emergency cutoff electronic circuit power supply ends Pole pipe may can not be isolated entirely from the power supply of this two emergency cutoff electronic circuits in addition it is also necessary to urgent by this two Other signals that are respectively mutually related of shutdown electronic circuit are electrically insulated.
Specifically, still a first emergency cutoff electronic circuit 11 is included with described emergency cutoff circuit and one second tight As a example anxious shutdown electronic circuit 12, it is assumed that described first emergency cutoff electronic circuit 11 is arranged on Modular UPS simultaneously In machine plate module, described second emergency cutoff electronic circuit 12 is arranged in the bypass module of Modular UPS, due to described and machine plate Module and bypass module can be electrically connected with the monitoring module in Modular UPS simultaneously, and, except supplying in described monitoring module Beyond electric power supply signal, the associated signal such as other B_CAN_TX, B_CAN_RX and KB_EPO_IN are also had all to may be from and machine Plate module and bypass module, therefore, the backward diode merely with this two emergency cutoff electronic circuit power supply ends can not Enough completely the power supply of this two emergency cutoff electronic circuits is isolated entirely from, in order to exclude above-mentioned each associated signal to each The impact of emergency cutoff electronic circuit power supply, in the company of above-mentioned each associated signal and each emergency cutoff electronic circuit power supply A backward diode all can be added in connecing, to prevent from this being connected with each other, by signal, this two emergency cutoff being led to The power supply of circuit cannot be completely isolated problem.
