摘　　要：在分析500 kV变电站内瞬态电磁干扰特点的基础上,建立了一套能模拟站内开关操作引起的瞬态电磁场的电磁脉冲模拟器,说明了模拟器各组成部分的特点,并利用该试验系统针对下放到开关场中的保护及控制设备进行了一系列试验研究,分析了这类自动化设备对瞬态干扰的敏感性。On the basis of an analysis of the characteristics of transient electromagnetic disturbance in 500 kV substations, a set of electromagnetic pulse simulator for simulating the transient fields induced by switching operation is developed. The configurations of the pulse simulator are explained. The protection and control equipment in the switching fields is tested using the simulator to study the susceptibility of this kind of transferred equipments to transient disturbance in the transient field.
