摘要
介绍了开关柜局部放电检测常用方法,并列举了3种典型的局部放电模型。利用地电压法对开关柜进行现场测试过程中有效发现异常故障,取得了实际效果。开关柜局部放电检测技术应当在记录大量典型模型数据的基础上来不断完善。
This article described the common methods used to conduct the switch cabinet partial discharge, and listed three kinds of typical partial discharge models. Using ground voltage method to achieve the on-site testing of switch cabinet to find the abnormal failure effectively, and reach the actual effect. The technology of conducting live detection and diagnosis in switch cabinet partial discharge should be optimized based on a large number of recorded typical model data.
