一起雷击引起的110kV变电站直流系统故障分析及处理

雷电发生一瞬间释放几十安培甚至几百万安培的电流,由于电网运行环境比较恶劣,很容易受到雷击,造成电气设备温度升高从而引起电力故障.因此,变电站在建设过程中要做好防雷措施.本文主要分析了110kV变电站受到雷击以后直流系统发生故障,以及故障原因和处理方式,希望能提高变电站运行水平.

Analysis and treatment of DC system fault in 110kV substation caused by lightning stroke

Lightning releases an electric current of tens of amperes or even millions of amperes in an instant. Due to the bad operating environment of the power grid, it is easy to be struck by lightning, resulting in the rise of electrical equipment temperature, resulting in power failure. Therefore, the substation should do well lightning protection measures in the construction process. This paper mainly analyzes the fault of DC system after lightning stroke in 110kV substation, as well as the causes and treatment methods, hoping to improve the operation level of substation.
