摘要
随着特高压变电站建设的不断推进以及气体绝缘全封闭组合电器(GIS)的广泛使用,由隔离开关和断路器操作引起的快速暂态过电压(VFTO)带来的危害越加明显。在某特高压变电站启动过程中,当断路器进行合、分合分操作时,电压互感器下方用以接地的电磁锁内部装置电路被击穿,接地刀闸控制电源(与电磁锁共用)空开跳闸。事故发生后,结合现场实际情况认为电磁骚扰导致电磁锁击穿、空开跳开的途径有两种可能,为了分辨电磁骚扰的耦合路径,找出骚扰信号的来源,设计了两种试验方案,最终确认了骚扰信号是从电缆内部进来的,通过电源线和信号线施加在电磁锁上,使电磁锁对外壳放电,引起地刀控制电源空开跳闸。
With the continuously proceeding of the construction of the UHV substation and the wildly used Gas Insulated Switchgear(GIS), the damage caused by the VFTO which is aroused by the operation of the isolated switch and circuit breaker becomes more and more apparent. In startup process of a UHV substation, when operating the switch on or off in the circuit breaker, at the bottom of the potential transformer, the internal circuit in the electromagnetic lock device used for grounding was breakdown and air break switch in the earthing knife-switch of the control power source(shared with electromagnetic lock) tripped. After the accident, combining with the on-site actual situation, it is believed that there are two possible reasons for the electromagnetic disturbance leading to the breakdown of the electromagnetic lock and the tripping of the air break switch. In order to distinguish coupling paths of the electromagnetic disturbance and discover the source of the disturbance signal, two test solutions are designed. Eventually, it is identified that the disturbance signal comes from the internal of cable which applied the disturbance signal on the electromagnetic lock via power line and signal line, making the electromagnetic lock discharge the electricity to its enclosure and thus leading to trip of air break switch in the earthing knife-switch of the control power source.
