摘要
为了更为有效地测量与研究电力外绝缘表面污秽的离子成分,首先从防污发展的需求入手,分析了进行电力外绝缘污秽化学成分研究的必要性。其次研究了使用离子交换色谱进行离子成分测量的具体方法,并使用该方法测量了珠江三角洲地区电力外绝缘自然污秽的离子成分。主要考虑污秽物对污闪电压的贡献和溶解度,制定了阴阳离子配对原则,并进行了人工配对,得出了自然污秽的化合物形式,发现了一种新的主要化学成分NH4NO3。最后讨论认为离子交换色谱法可用于批量测量电力外绝缘污秽离子成分;未来硝酸盐可能代替硫酸盐,成为电力外绝缘自然污秽的主要成分,由于硝酸盐不同于硫酸盐的性质,届时将面临更为严峻的防污形势。
In order to measure and study the ion composition of natural contamination more effectively,firstly,we analyzed the necessity of studying chemical composition of natural contamination,according to the development of anti-pollution demands.Secondly,the measurement method of natural contamination ion composition was put forward based on ion chromatography analysis,and was used to measure the natural contamination ion composition in Pearl River Delta area.Thirdly,according to the contribution of contamination to flashover voltage and the solubility of contamination,principles used to make the ions in pairs were analyzed and used to get the compounds of contamination.And a new kind of main chemical composition NH4NO3 was found out.Finally,a conclusion can be drawn that ion exchange chromatography can be commonly used to measure natural contamination ion composition.Nitrate will take the place of sulfate and become the main natural contamination composition in the future.As to the different nature between nitrate and sulfate,the future of anti-contamination flashover would be more serious.
