摘要

在35 kV空母线系统中

真空断路器投切电抗器可能会产生较高的操作过电压

甚至引发谐振。笔者基于某220 kV变电站35 kV空母侧由投切电抗器而引发的多起故障

根据故障现象及系统的实际运行情况

对与电抗器操作相关的操作过电压、谐振等问题分别进行了计算和分析

得出变电所由投切电抗器引发的多起故障中

PT熔丝熔断主要由谐振引起

所变故障以及电抗器故障发生的主要原因与其自身绝缘相关

并给出了解决措施和建议。

Abstract

High over-voltage or even resonance may occur due to vacuum circuit breaker switching to shunt reactors in 35 kV bus bar system.On the basis of several faults caused by vacuum circuit breaker switching to shunt reactors in a 35 kV bus bar system at a 220 kV substation

calculations and analysis of the switching over-voltage and resonance are performed in this paper by considering the phenomena of faults and operational conditions of the system.The results indicate that among the faults due to switching to shunt reactors

the faults of PT fuse blowing were caused by resonance

and the faults of the transformers and the reactors were related with their insulation.Consequently

some measures and suggestions are put forward.
