摘要
针对电磁式母线充电保护仅考虑对母线和线路充电,没有考虑主变充电和充电保护“长投”运行方式的设计缺陷,从保护的基本原理、二次回路、操作灵活性、安全性和可靠性等方面进行了分析,提出并实施了改进措施。试验结果表明,改造后的母线充电保护装置完全满足设备运行的各种要求。
Aiming at the design deficiency of the electromagnetic busbar charging protection that only considering bus and line charging, the paper makes an analysis from the aspects of fundamental principle, secondary loop, flexibility of operation, security, and reliability. The improvement of electromagnetic system busbar charging protector is put forward. The validity of upgrading option has been demonstrated by practical tests.
