电力系统潜供电弧自灭特性的模拟研究

Test Study on Self-Extinction Behavior of Secondary Arc on Power System

本文叙述了对交流高压及超高压电力系统潜供电弧自灭特性，以及以２０．２ｋＶ模拟电弧进行试验研究的结果。潜供电弧的电流值范围为１１．２～７８．８Ａ，它可以覆盖２２０～１１５０ｋＶ各电压等级线路的潜供电弧参数。

Results of test study on self-extinction behavior of secondary arc on HV and UHV power systems are presented in this paper. The tests are performed on a 20. 2kV simulated circuit,which provides secondary arc current from 11. 2A to 78.8A, and over the range of the parameters of 220～1150 kV transmission lines.
