技术领域technical field

本发明涉及高压领域，具体而言，涉及一种监测方法及装置、系统。The present invention relates to the field of high voltage, in particular to a monitoring method, device and system.

背景技术Background technique

每年春季，杨树、柳树等植物大量释放飘絮物，这些飘絮物重量轻、体积小，能穿过高压设备室的通风口或百叶窗进入室内设备区，在室内很容易聚集成团。飘絮物的主要成分为纤维素，有很强的吸水性。当空气湿度增大时，成团的飘絮从空气中吸收水分，其绝缘能力大幅下降。当成团的飘絮靠近设备外绝缘时，可能引发闪络。特别是对于立式的穿墙套管，若飘絮在套管周围堆积成团未被及时清理，可能引发闪络造成套管损坏、设备停电。Every spring, plants such as poplars and willows release a large amount of floating flocs. These floating flocs are light in weight and small in size, and can enter the indoor equipment area through the vents or shutters of the high-voltage equipment room, and easily gather into clusters indoors. The main component of floating floc is cellulose, which has strong water absorption. When the air humidity increases, the clustered flocs absorb moisture from the air, and their insulating ability is greatly reduced. When a group of floating flocs is close to the external insulation of the equipment, it may cause a flashover. Especially for vertical wall-piercing bushings, if the floating lint accumulates around the bushing and is not cleaned up in time, it may cause flashover, damage to the bushing, and power outage of the equipment.

目前，变电站值班模式已经普遍无人化，对飘絮的监测主要依靠人工巡视来实现，尚未有针对飘絮物进行在线监测的系统。人工巡视的频次是按照变电站是按照变电站在电网中的重要程度来安排的，重要的变电站巡视频次多，不重要的变电站巡视频次少，这就导致一些可能危及设备外绝缘的飘絮团无法被及时发现并处理，从而危害电网安全。At present, the duty mode of substations has been generally unmanned, and the monitoring of floating flocs is mainly realized by manual inspection, and there is no online monitoring system for floating flocs. The frequency of manual inspections is arranged according to the importance of substations in the power grid. Important substations have more inspections, and unimportant substations have fewer inspections, which leads to some floating flocs that may endanger the external insulation of the equipment. If it cannot be detected and dealt with in time, it will endanger the security of the power grid.

针对上述现有技术中飘絮团无法被及时发现并处理从而危害电网安全的问题，目前尚未提出有效的解决方案。Aiming at the above-mentioned problem in the prior art that the floating flocs cannot be detected and dealt with in time, thus endangering the safety of the power grid, no effective solution has been proposed yet.
