摘要
介绍开关柜试验模型系统结构和接线图,分析在针板放电、内部放电、沿面放电、悬浮放电等4种局部放电模型下,TEV检测系统输出值和脉冲电流法检测放电量幅值之间的对应关系,试验结果表明TEV法与脉冲电流法有良好的相关性,TEV法对开关柜局部放电有一定预防作用。
The structure and connection map of switch cabinet experimental model system is introduced, and the corre-sponding relationship between the TEV （Transient Earth Voltage） method and current pulse measurement was studied in the four partial discharge model as the needle plate dis- charge, internal discharge, surface discharge and floating discharge. The results show that the two methods have a good correlation. TEV method can pretend switch cabinet partial discharge.
