摘要

断线过电压一般发生在配网中

与配网导线较细、杆塔较低、宜受外力破坏有关。本文介绍了一起发生几率小、容易被忽视的因真空灭弧室真空度下降造成的断线过电压情况

并对其发生过程进行了详细分析

提出了防范措施。

Abstract

Broken wire overvoltage usually happens in distribution power grid because the wires in such grid are easily damaged by outer forces due to the thinner conductors and lower wire pole. This paper introduces a very lower probability and easily neglected broken wire overvoltage caused by decreased vacuum degree of the vacuum interrupter. The generating process of the overvoltage is analyzed in detail and the precautions are suggested.
