摘要/Abstract

摘要： 为了研究复合绝缘子积污腐蚀表面与泄漏电流的关系，以人工污秽试验的方法制备试样，采用泄漏电流测量装置分别按积污时间、盐密、灰密、pH值为变量对试样的泄漏电流进行测量，并分析了上述变量对泄漏电流的影响。结果表明，复合绝缘子表面泄漏电流随着试样腐蚀时间的增加而增加，且酸性环境对其影响大于碱性环境；相较于灰密对积污腐蚀表面泄漏电流的影响，盐密的变化对泄漏电流的影响更明显；泄漏电流分别随着电压的提高和加压时间的增加而增大。

关键词: 复合绝缘子, 盐密, 灰密, pH值, 泄漏电流

Abstract: In order to study the relationship between leakage current and composite insulator surface with corrosion product fouling, samples are prepared by artificial pollution test method, and the leakage current testing equipment are used to measure the leakage currents of samples by taking the pollution time, salt density, ash density and pH value as variables, and the influences of the variables on the leakage current are analyzed. The results show that the leakage currents on the composite insulator surface increase with the corrosion time, and the influence on leakage currents in the acidic environment is greater than that in alkaline environment; compared with ash density, influence of salt density change on the leakage current is more obvious, and the leakage current increase with the increase of the voltage and the applied voltage time.

Key words: composite insulator, salt density, ash density, pH value, leakage currents
