摘要

雾霾环境中的输变电设备外绝缘积污规律有其特殊性

为了研究雾霾持续时间与雾霾成分对外绝缘积污的影响

用硅橡胶试片与XP-70绝缘子进行模拟积污试验。试验结果表明:试片在雾霾环境中的积污速率快且难以达到饱和

悬浮颗粒物的沉降对积污起主要作用;绝缘子在雾霾环境中的积污速率较快且迅速达到饱和

悬浮颗粒物的扩散与粘附对积污起主要作用。此外

增加雾电导率以及霾成分中含有的可溶且能电离的物质有利于积污的增加。通过预涂高岭土与不预涂高岭土的绝缘子对比积污试验

发现雾霾时绝缘子表面的初始灰密对绝缘子等值盐密的增长有微弱影响。

Abstract

Pollution rules of power transmission equipment exposing in the fog-haze environment has its own peculiarities. In order to study the duration of haze and smog components affecting the contamination of external insulation

the silicone rubber specimen and XP-70 insulators are used to simulate the contamination tests. The results show that the contamination rate in the fog-haze environment is fast and hard to reach saturation. Suspended particulate deposition play a major role in the contamination. The contamination rate in haze environment more quickly reaches saturation. Suspended proliferation and adhesion of the contamination particles play a major role. In addition

the increase of fog conductivity and dissolvable electrolyte in the haze promote the increase of contamination. Through the insulators test in the presence and absence of Kaolin

results show that the NSDD of insulators have a marginal impact on the ESDD growth in the fog-haze environment.
