摘要
文章针对110～220kV架空输电线路的防污技术,基于线路状态清扫的思想,通过对绝缘子盐密测试数据的统计分析总结出了绝缘子积污增长速率公式.并应用绝缘子污闪机理,通过对表面电导率和污闪电压与盐密相关性的试验研究,提出了绝缘子盐密控制值的估算方法和线路清扫依据.
To implement the depollution and the condition based cleaning of 110-220kV transmission line, through the statistics and analysis of the measured salt density data of the insulator strings the formula for dirt retention increasing velocity is obtained. Using the pollution flashover mechanism for insulators and through the test and research of the correlativity among the surface conductivity, pollution flashover voltage and salt density an estimation method for the controlling value of insulator salt density and the criterion for transmission line cleaning are put forward.
