| 中文摘要: |
| 断路器在开断电容器组等容性负载时发生重燃，会产生高幅值的重燃过电压，威胁并联补偿装置和电网安全。开关柜动作时会在空间辐射能够用于判别是否发生重燃现象的电磁波信号，本文阐述了基于辐射电磁波信号带电检测开关柜重燃现象的检测原理，对红河供电局所属无功投切开关柜进行现场检测，发现了存在重燃现象的开关，证明了该方法可以用来检测开关柜的重燃现象。 |
| 英文摘要: |
| Circuit breakers will reignite when they switch capacitor groups and other capacitive loads, and they will generate high- amplitude reburn overvoltages, threatening the safety of parallel compensation devices and power grids. When the switchgear operates, it radiates electromagnetic signals in the space that can be used to determine whether a rekindling phenomenon has occurred. This article elaborated on the detection principle of the re-ignition phenomenon of the switch cabinet based on the radiated electromagnetic wave signal on-line monitoring, and carried out the on-site inspection of the reactive power switch cabinet belonging to the Honghe Power Supply Bureau. A switch with re-ignition was found, which proved that this method can be used to detect the re- ignition of the switch cabinet. |
