摘　　要：随着智能电网建设的快速发展,智能开关设备应用越来越广泛,其可靠性更加受到各方关注。为了对智能化GIS设备智能采集单元的可靠性进行试验验证,笔者通过隔离开关开合母线充电电流方式1以及方式3试验对其进行了相关研究。通过一例363 kV智能GIS在隔离开关开合母线充电电流方式1、方式3试验中TEV的测量分析,介绍试验回路及试验过程,并对测量得到的TEV数据进行了分析,通过试验数据总结了在此例试验中TEV电压的分布情况,并对产生此测量结果的原因进行了分析。文中的试验研究对于验证智能化设备抗电磁干扰能力的试验方法提供了一些经验。With the rapid development of smart grid construction,smart switehgears are used more and more broadly,and their reliabilities have attracted even more wide attention. In order to verify the reliability of the smart data collecting unit of smart GIS by testing,related research through the test duty 1 and 3 of disconnector switching bus-charging current have been done. In this paper,the TEV is measured through test duty 1 and 3 of disconnector closing and opening bus charging current in 363 kV smart GIS, the test process and test circuits are introduced. The distribution of TEV voltage is summarized from the measured TEV data,and the reasons are analyzed. The experimental study in this paper provides some experience to the test method for verifying the antielectromagnetism interference ability of smart switchgears.
