摘要
本文针对一起某110kV变电站110kV备自投装置拒动事故,通过事故前后电网运行方式变化及装置开入、开出量变化,结合备自投装置运行原理,分析发现相关断路器合后位置继电器存在缺陷,造成装置存在安全隐患,并提出了改进措施。
On a 110kV substation 110kV auto-switching malfunction accident, the accident of power network operation mode, the device of entry and open volume change, which we can analyze that the blemish exists on the associated circuit breaker closed position relay, combined with auto- switching operation principle. The blemish causes device hidden safety problems, and then we put forward the improvement measures.
