基于灰关联算法分析环境因素对高海拔±800kV线路绝缘子泄漏电流的影响
Influence of Environmental Factors on Leakage Current of ±800 kV Line Insulators at High Altitudes Based on Grey Relation Analysis
摘要
Abstract
To analyze the influence of environmental factors on leakage current of ±800 kV lines insulators, long-term charged assessment on the ±800 kV line insulators was carried out in the live examination field for UHV DC equipment. We statistically analyzed the leakage current of three material (porcelain, composite, glass) ±800 kV lines insulators under natural pollution condition, figured out the correlation between the environmental factors (environment humidity, temperature, temperature alteration ratio) and the leakage current of insulators based on grey relation analysis, and found out the most important factor influencing the leakage current. The results show that the most significant factors are environment humidity, and the surface humidity is the most important factor, the temperature alteration ratio has a greater influence on leakage current, and the correlation between the leakage current and the environmental factors is similar.关键词
