输电线路绝缘子串防冰闪措施分析

Measures for Preventing ice Flashover of Insulator Strings in Transmission Lines

当前,受厄尔尼诺现象的影响,全球的天气变化无常。近两年来,我国经常出现大范围的冰雨现象,导致输电线路绝缘子串被冻雨覆盖,从而影响了电能的输送,造成国家经济财产的损失。本文分析了输电线路绝缘子串出现冰闪的影响因素,并进一步探讨了如何预防输电线路绝缘子串冰闪现象的相关措施,希望能给相关的专业人士以有益的启发,从而确保输电线路的安全、稳定运转。

At present, influenced by El Nio phenomena, the weather around the world is changeable. In recent two years, a largescale ice-rain phenomenon often appears in China, which results in insulator strings of transmission lines being covered by freezing rain, thus affecting the transmission of electric energy and causing the loss of national economic property. Next, this paper analyses transmission lines. Influencing factors of icing flashover of road insulator strings are discussed, and relevant measures to prevent icing flashover of transmission line insulator strings are further discussed. It is hoped that these measures can provide useful inspiration to relevant professionals, so as to ensure the safe and stable operation of transmission lines.
