一起JSZF-10G1型电压互感器电压异常情况分析

Analysis of an unusual voltage situation of JSZF-10G1 voltage transformer

结合10kV旧式三相五柱式电压互感器对10kV不接地系统单相接地时JSZF-10G1型电压互感器出现二次电压异常情况进行分析,并提出10kV不接地系统应用JSZF-10G1型电压互感器的二次电压回路设计建议和注意要点。

This paper unifies the 10kV old-style three-phase five-pole voltage transformer to analyse unusual secondary voltage situation of JSZF-10G1 voltage transformer in the 10kV ungrounded system. The important points and design proposals of secondary voltage circuit using the JSZF-10G1 voltage transformer in the 10kV ungrounded system are put forward.
