摘要

在空气绝缘变电站（air insulated substation

AIS）中

隔离开关操作产生的电弧是变电站最主要的电磁干扰源

会在空间中产生高频的电磁辐射并耦合到二次设备上

影响二次设备的正常运行。为了研究隔离开关操作引起的瞬态磁场

文中设计了模拟实际隔离开关操作的骚扰源系统

利用该系统研究了110kV AIS隔离开关分合操作所产生的磁场随母线参数、隔离开关触头距离、电源容量变化的规律。结果表明:该系统可以产生频率在1.1 MHz至1.8 MHz之间、最大磁场强度为235 A/m的空间磁场

与现有文献报道的户外变电站隔离开关操作磁场实测数据相吻合。

Abstract

In air insulated substation

the arc produced by the disconnecting switch operation is the most seriouselectromagnetic interference source. It can produce electromagnetic radiation in space with high frequency and cou-ple to the secondary equipment

affecting the normal operation of the secondary equipment. In order to study the tran-sient magnetic field caused by isolation switch operation

a disturbance source system which can simulate the actualdisconnecting switch operation is designed in this paper. Then the influence on the magnetic field by the bus parame-ters of the 110kV air insulated substation is studied. The results show that the disturbance source system can pro-duce space magnetic field of 1.1 MHz to 1.8 MHz in frequency and 235 A/m in maximum strength

which is coincident with the existing measured data of the disconnecting switch operation in the outdoor substation.
