Discussion on the Reason for Actuation of Overcurrent Protection for 35kV Capacitor Bank in Changli Substation
摘要
昌黎站两组35kV电容器过流保护在运行中同时动作跳闸
这种情况在我公司还从来没有发生过
而且也没有看到过其它文献的报导
为了总结经验教训
提高设备安全运行水平
本文分析了跳闸原因
为了避免今后发生类似的问题
在继电器的选型上提出了看法。
Abstract
Overcurrent protection for two sets of 35kV capacitors in Changli substation actuated simultaneously leading to the circuit-breaker tripping. Such cases never occurred in our Corporation
and we have never heard relevant reports. In order to sum up the experience and lesson to promote the safe operation level of the facilities
the article offers a reasonable analysis to avoid similar problems. Some suggestions are also given on relay selection.
