变电站一次设备过电压对其二次回路影响及其防范措施研究

Study on the influence of the overvoltage on the secondary circuit and its preventive measures

本文研究过程中以某变电站二次回路继电器频繁故障为基础进行一次设备过电压对其二次回路影响分析,提出感应过电压以及过谐振电压对二次回路的影响,在此基础上提出防范的措施。

This paper studies the process of taking a substation secondary loop relay frequent fault overvoltage for the second time a equipment based on loop impact analysis,put forward induced over-voltage and the influence of a harmonic voltage of secondary loop,on the basis of this puts forward preventive measures.
