广州地区输电线路沿线绝缘子自然污秽化学成分的来源分析

Source Analysis on the Chemical Composition of Natural Contamination on the Line Insulator in Guangzhou Area

为研究广州地区线路绝缘子表面自然污秽化学成分的来源,建立了自然积污监测点,现场采集自然污秽并测量了其化学成分。使用富集因子分析、相关性分析和因子分析3种分析方法,分析了绝缘子表面自然污秽化学成分的来源,发现绝缘子表面自然污秽化学成分主要来源于人为污染,不同污染源有不同的污染物化学成分;确定了绝缘子表面自然污秽积累的主要污染源。该分析方法可以确定某一区域或者地区的主要污染源,以此为依据可以通过控制个别主要污染源的排放量,减少绝缘子表面自然污秽积累,达到有效预防污闪的效果。

In order to investigate the source of chemical composition of natural contamination on line insulator in Guangzhou area,nhtural contamination measurement sites were established, from which the natural contamination was collected, and chemical composition was measured. By enrichment factor analysis, correlation analysis and fac- tor analysis, the source of chemical composition of natural contamination on line insulator was studied. And the main pollution sources of chemical composition of natural contamination on line insulator were configured. It is found that the chemical composition of line insulator comes mainly from man made pollution. Different pollution sources have different chemical compositions. The analyses reveal that the main pollution source of the composition on line insula- tor in some region or area can be found out. Thereby, by reducing the specific pollution emissions, the natural con- tamination on line insulator can also be reduced. Therefore, the contamination flashover can be prevented effective- ly.
