摘要
500kV和平变电站从2007年投运至今已有十余年的时间,保护动作跳闸的事情也是比较常见的,但是断路器本体三相不一致动作跳闸的尚属首例,即使是整个云南电网而言断路器本体三相不一致动作跳闸的也是很少的。因此,文章对该站这一次跳闸进行了实例分析。
It has been more than ten years since the 500 kV Heping Substation was put into operation in 2007.It is common for trip of protection action,but the three-phase inconsistent action tripping of the circuit breaker itself is the first case,even for the entire Yunnan power grid.Therefore,this paper analyzes the trip of this station.
