输电线路污闪分析及预防措施

Analysis of Pollution Flashover on Transmission Line and its Prevention Measures

输电线路是电力系统中的重要组成部分,与电力系统运行是否稳定安全具有直接关联。在输电线路的长期运行过程中,由于线路中绝缘子受到外界环境的污染,容易出现污闪现象。污闪现象的发生轻者容易造成停电,对人们的正常用电造成影响,重者会引发安全事故,对人们的生命财产安全造成威胁。文章首先分析了输电线路污闪原因,然后介绍了输电线路污闪故障的危害性,最后提出了防治输电线路污闪的有效措施。

Transmission line is an important part of the power system,and directly linked to the stability of power system operation security.In the long operation of transmission line,because of the line insulator contamination by the external environment,it is easy to cause to pollution flashover.Flashing phenomena of light easy to cause power cut,had an influence on using electricity normally,severe cases can lead to accident;pose a threat to people's life and property safety.This article firstly analyzed the reasons of pollution flashover of transmission line,and introduced the dangers of pollution flashover on transmission line fault,finally put forward effective measures to control pollution flashover of transmission line.
