Dianci bileiqi, 2016 在河南省境内的特高压交、直流输电线路采集绝缘子表面的自然污秽物并测定了污秽物中可溶性物质的化学成分,分析了试验绝缘子表面自然积污可溶性物质金属阳离子的富集程度。研究发现,河南省地区特高压交、直流输电线路绝缘子自然积污的可溶性物质中均含有金属阳离子Ca2+、K+、Mg2+、Na+、Zn2+,均含有阴离子SO42-、NO3-、Cl-、F-;雾霾天气可能是造成绝缘子表面SO42-和NO3-浓度较大的一个原因,但雾霾天气与绝缘子污秽物可溶性物质中金属阳离子的沉积没有直接关联;在试验所在地区 ...

Gaoya dianqi为了研究带电污秽颗粒对绝缘子表面积污、电场分布的影响及空气域电晕放电现象，以FXBW-35/70绝缘子为研究对象，采用多物理场耦合有限元软件Comsol Multiphysics搭建了AC-DC、湍流、带电颗粒相互作用及颗粒运动的耦合风洞模型，进行了带电颗粒对绝缘子表面积污、电场和空气域电晕放电分布研究。结果表明：风速越大，迎风区积污速度快于其他区面；粒径增大时，迎风面积污严重，背风区积污很小，侧风区基本无变化；染污中迎风区伞裙表面的电位和电场畸变最为严重，背风区次之，染污后伞裙表面电位、电场有所缓和 ...
