浅谈500 kV断路器瓷套管爆炸原因

The Reason of Porcelain Bushing Explosion of 500 kV Circuit Breaker

对爆炸套管A厂家的套管结构与其他国内厂家进行对比,并对其进行电场仿真计算,分析电场分布云图,电场仿真计算结果表明A厂家设计的瓷套管内部场强高于国内其他厂家,设计的瓷套管裕量不足,可能会导致套管内部发生放电。

The explosion of manufacturer A casing pipe structure compared with other domestic manufacturers,and carries on the electric field simulation calculation,analysis of the electric field distribution nephogram,electric field simulation results show that the porcelain manufacturer A design casing internal field strength is higher than other domestic manufacturers,design of porcelain bushing allowance is not enough,can lead to internal casing discharge.
