摘要

为了对隔离开关动作产生瞬态辐射场的波形特征进行研究

文中对330 kV开关站内隔离开关动作所产生的VFTO辐射电场进行了测量与分析。研制了一套能够适应复杂电磁环境应用的电场测量系统;开展了针对不同线侧隔离开关操作所产生VFTO辐射电场的测量工作;从时域和频域对其测试结果进行了研究分析。研究结果显示:距开关3 m处

隔离开关动作产生的辐射电场强度幅值可达4.65 kV/m;辐射电场频谱分布在200 MHz以下

且在某几个特征频率上集中分布;母线侧及出线侧隔离开关操作产生的VFTO辐射场具有不同的频谱分布;隔离开关的分闸及合闸操作产生的VFTO辐射场具有不同的频谱分布。

Abstract

In order to study the waveform characteristics of the transient radiation field produced by the operation ofdisconnector

the radiated electric field generated by the operation of disconnector in the 330 kV Switching station ismeasured and analyzed. First

an electric field measurement system based on optical fiber is developed. Then veryfast transient overvoltage（VFTO）radiation field generated by operation of disconnector on the different side is mea-sured in the switch station. The measurement results are analyzed both in time domain and frequency domain. The re-sults show that amplitude of the electric field generated by the operation of disconnector at 3 m away from the discon-nector can reach 4.65 kV/m. The radiated electric field has a spectrum below 200 MHz

especially in some character-istic frequencies. The VFTO radiation field generated by the operation of disconnector on the busbar side and outgo-ing line side has different spectrum distribution. The VFTO radiation field generated by the opening and closing oper-ation of disconnector has different spectrum distribution.
