基于电容器消除500kV开关机械特性试验感应电危害的研究

Relieving Damages Caused by Faradic Electricity from 500 kV Switch Mechanical Characteristics Test Based on Capacitor

500 kV变电站场地感应电非常强烈,给检修作业人员的安全带来威胁。利用电容器,对500 kV开关机械特性试验时的感应电进行了研究。结果表明,利用电容器能使感应电压降低至安全范围,同时不影响试验数据。

The intense faradic electricity from the 500 kV substation is a menace to the safety of the maintainers and operators. By utilizing the capacitor,the author of this paper conducts a study on the faradic electricity from the mechanical characteristics test of the 500 kV switch. The analysis shows that by utilizing the capacitor the faradic electricity is reduced to the safe level while the experimental data is not affected.
