摘要
分析了35 kV电缆配电网中变电站进线避雷器的事故案例,研究了35 kV、6 kV中压配电网中几种常见过电压的幅值,并与阀型避雷器和氧化锌避雷器的放电电压相比较,对装设进线和馈线避雷器的实际效果和合理配置提出见解。
This paper analyzed the accident case concerning arrester of substation in 35 kV cable distribution net, studied the values of several commonly used over voltage in 35kV and 6kV middle voltage distribution net, and compared it with the discharge voltage of valve arrester and zinc oxide arrester, based on which it brought forward ideas for actual effects and reasonable configuration for furnishment of incoming and feeder arrester.
