摘　　要：在牵引供电系统中,因绝缘子污闪引发的变电所跳闸停电事故时有发生。由于现场测量、勘察接触网用绝缘子污秽水平的难度较大,本文依据污秽闪络产生的机理,模拟现场运行环境,研制一套接触网用绝缘子污闪测试系统,能够在实验室模拟绝缘子的污闪现象,测量并监控绝缘子表面泄漏电流,为研究解决绝缘子污闪问题奠定基础。In traction power supply system,the accident of power off caused by tripping of substation occurs frequently due to insulator pollution flashover.Since there are difficulties in the survey and measurement of pollution level of insulators at site,the paper,in accordance with the mechanism of generating of pollution flashover,simulates the site operation environment,develops a testing system for test of pollution and flashover of insulators for OCS.It is able to simulate the pollution flashover of insulators in the laboratory,measure and monitor the surficial leakage current of insulator.It lays a foundation for studying and solving problems of pollution and flashover of insulators.
