摘要
针对广东500 kV北郊站220 kV北石乙线开关爆炸事故,利用ATP-EMTP软件进行了仿真计算,计算结果表明:事故可能是由连续雷击造成的,北郊变电站的输电线进线段不设防(未装避雷器)是重要原因之一,北郊变电站线路侧无避雷器保护,断路器在开关断开的情况下难以抵御雷电侵入波,因而造成北郊变电站断路器发生爆炸。
Based on ATP-EMTP, this paper calculated and researched the explosion accident of 220 kV SF6 Breaker in Guangdong 500 kV BeiJiao substation. The findings showed that： the accident was possibly caused by the continuous lightning, and one of the main factors was the lack of arrester on the incoming line before the substation. The circuit breaker could not withstand the lightning invasion surge, and led to its explosion for no lightning arrester protection was set on the line side in Bei-Jiao substation.
