Abstract: 输配电系统中 ,污秽的绝缘外表面在潮湿天气所发生的沿面闪络是引起输电线路故障的主要原因之一。加强对绝缘表面在此种情况下电导特性的基础研究 ,有助于进一步探究表面电导与污秽闪络的关系 ,有利于进行较为准确的绝缘在线监测工作。并可根据研究结果 ,采取相应措施以改进绝缘防污性能、进行有针对性的清洗、检修及更换等 ,以达到减少污闪事故的发生率、保障供电可靠性和安全性的目的。本文以污秽玻璃片为实验对象 ,在人工雾室中对其表面电导特性进行了大量的基础实验 ,得到了相关的实验结果。通过对实验结果的分析和总结 ,得到了一些有益的结论
In the power transmission and distribution system, the power supply failure caused by the polluted flashover of insulator has been becoming one of the most serious factors, especially under moist weather.Taking the polluted glass sheet as experimental subject, we have measured its surface conductance in fog chamber and obtained a large number of experimental data.Through analyzing and summarizing the experimental data, we have gained useful conclusions which are helpful for the insulation monitoring on line, model building and so on.
