摘要:
配电开关一二次设备标准化、集成化发展对长期处于复杂电磁环境下的二次设备可靠运行提出了更高要求。搭建雷电冲击电压试验平台，采集电压互感器二次侧、馈线终端（FTU）输入及输出电压信号，分析得到冲击电压引起的二次设备端口电磁干扰频谱分布，并设计滤波方式对其进行有效抑制。结果表明：雷电冲击对电压互感器、馈线终端均会产生瞬态高频电磁干扰，辐射耦合引起的干扰电压峰值约为3kV，频带为3.6～16.4MHz；传导耦合引起的干扰电压峰值约为4.5kV，频带主要分布在1.2～6.7MHz、12.5～20MHz，加入滤波装置后正负向干扰电压峰值均降低超过23%，且未发生故障现象。该试验结果为一二次融合配电开关二次设备电磁兼容研究提供参考。
Abstract:
The standardization and integration development of primary and secondary equipment of power distribution switches puts forward higher requirements for the reliable operation of secondary equipment under long-term complex electromagnetic environment. This paper builds a lightning impulse voltage test platform, and collect the secondary side of the voltage transformer, the feeder terminal unit (FTU) input and output voltage signals, and analyze the above-mentioned waveform to obtain the electromagnetic interference spectrum distribution of the secondary device port caused by the impulse voltage, which is effectively suppressed by the filtering method. The test results show that the lightning impulse will produce transient high frequency electromagnetic interference to the voltage transformer and feeder terminal unit, the peak value of the interference voltage caused by radiation coupling is about 3kV, the frequency band is 3.6~ 16.4MHz the peak value of the interference voltage caused by conduction coupling is about 4.5kV, the frequency bands are mainly distributed between 1.2~6.7MHz and 12.5~20MHz, after adding the filter, the positive and negative interference voltage peaks are reduced by more than 23%, and no fault occurs. The test results provide reference for the EMC research of secondary equipment for primary and secondary fusion distribution switches
