关于安棚变电所开关拒动故障的判断及处理措施

Judgement and Treatment of Switch Failure in An Peng Substation

无人值班已成为铁路系统牵引变电所的发展趋势,而电动隔离开关为整个铁路供电系统的重要组成部分,一旦发生故障将影响整个铁路供电系统的正常运行,直接影响列车的通行能力。就管内宁西线安棚变电所投运后,由南瑞保护装置引起的多次电动隔离开关拒动原因进行分析,并结合日常运行维护,深入探讨电动隔离开关调试后隔离开关拒动的处理。

No one has become the development trend of railway system traction substation, and the electric isolation switch is an important part of the whole railway power supply system. Once the failure occurs, the normal operation of the whole railway power supply system will be directly affected, and the capacity of the train is directly affected. This paper analyzes the reasons for the rejection of several electric isolation switches caused by Nanni protection device after the operation of the substation of NANNIN west line, and discusses the treatment of the isolation switch after the electric isolation switch debugging.
