摘要
阐述了一起组合电器式220 kV线路间隔保护跳闸之后的检查分析过程,确定该故障是由于刀闸合闸不到位导致触头烧损引起的,并提出了相应解决办法和防范建议,为组合电器在电力系统中安全、稳定运行提供了参考依据。
The analysis on a bay protection trip of gas insulated switchgear(GIS) in a 220 kV line is expounded, from which the fault is found due to the contact burning damage caused by insufficient closing of the isolation switch. The corresponding solutions and preventive suggestions are put forward, which offers a reference for the safe and stable operation of GIS in power system.
