Improvement of Anti-jumping Function of Medium Voltage Switchgear in a Certain Power Plant
摘要
We have conducted research on the anti-jumping methods for the 8BK30 switchgear and vacuum contactor of Tieling Power Generation Co., Ltd., which lack anti jump function. After discussing two common schemes, a new anti-jump scheme, namely time relay anti-jump, is put forward. In implementation, a setting method was designed. The new anti-jump scheme of time relay saves money and is easy to implement. The problem of anti-tump of switch is solved by innovative methods.
