| 摘 要： | 论述了绝缘子串在高电压作用下的电晕电流特性,并通过试验进行了验证。试验表明,绝缘子电晕电流具有统计特性,它与外加电压、绝缘子表面污秽程度及空气湿度等参数有关。用电晕电流法在线检测绝缘子运行状况是完全可行的。

| Abstract: | This paper elaborates theoretically the corona current characteristics of insulator strings under high voltage application and verifies them by experiment. It shows that the corona currents of insulator strings are of statistic characteristic and related with the parameters such as the applied voltage, the degree of its surface filth and the environmental humidity. A conclusion is obtained that the corona current method is practical to on-line monitor the insulating condition of insulator strings. |
