摘要
研究绝缘子的积污规律对合理确定清扫时机 ,并保证绝缘子的安全运行有重要意义。用局部表面电导率法研究了不同类型绝缘子的积污状况随时间的变化规律以及积污在绝缘子表面的分布状况。测量结果表明 ,雨水的自清洗作用对积污状况有显著影响 。
To assure the safe operation of the power systems, it is very important for utilities to choose the cleaning times by effectively evaluating the pollution levels on the surfaces of the high voltage insulators. The paper presented a survey of the variation of the amount of pollution on actual insulators in site over time and the distribution of contaminates on the insulator surfaces using the partial surface conductivity method. The results illustrate that the cleaning effect of rain has a notable influence on the contamination and that the partial surface conductivity method is an effective method for measuring the pollutants and a practical method for inspecting the contamination density of the insulators.
