酸雾对污秽绝缘子的交流电气特性的影响

Effects of acid fog on AC electric performance of polluted insulators

根据酸性湿沉降水pH值与电导率之间关系的试验结果,得出结论:绝缘子交流闪络电压随酸雾pH值的减小而降低。为此,分析了污秽绝缘子在酸雾中发生污闪的原因,以及试验溶液pH值对合成绝缘子憎水性的影响,可供有关工程人员参考和借鉴。

According to the test results of the relation between the pH value of acidic precipitation and the conductivity of solution, this paper indicates that the AC flashover voltage of an insulator decreases with the fall of the pH value of the acid fog, and analyzes the flashover cause of polluted insulators under acid fog condition. The influence of pH value of test solution on hydrophobicity of composite insulators is also studied.
