摘要
针对河津发电分公司300 MW机组在正常停机检修中,发现励磁回路灭磁开关主触头存在严重灼伤痕迹这一问题,进行分析,找出原因,提出了解决问题的方案,对程跳逆功率保护跳灭磁开关控制回路进行改进,最终解决了该问题。
For what happened in normal generator maintenance at Zhangze Electric Power Hejin Electric Power Generation Branch 300 MW unit, it was found out main contact terminal of field discharge switch at exciting circuit has been burned seriously. Through analyzing, the reason was found out and solutions were proposed. Finally, the controlled circuit of field discharge switch was improved and the problem was thus resolved.
