输电线路绝缘子污闪的机理

The Analysis about the Contaminant Lightning of Insulator String of Transmission Line

输电线路绝缘子污闪事故率虽然比雷害少，但造成的损失却比雷害大得多，所以对多种污闪现象进行物理、化学机理的探讨，并提出改进措施是很有必要的。

?The contaminant lightning breakdowll of insulator string can threaten the safety of thetransmission line. Based on the anslysis of physics and chemistry about phenomenon lightning. This paper presents some measure for contaminant lightning protection so as to increase the security of power network.
