Abstract

The radiation electric fields caused by the switching of 1100kV and 550kV GIS circuit breakers are measured by optical fiber measuring system. The waveform characteristics of radiation field and the frequency range are analyzed in this paper. The results show that the radiation field amplitude of 1100kVGIS circuit breaker actions can be up to 0.78kV/m, and the amplitude of radiation filed by 550kVGIS breaker produces can be up to 0.13kV/m. The frequency range of 1100kV GIS is from 20MHz to 100MHz, which is higher than the frequency range 0–5MHz of 550kV GIS. In addition, different types of tests can affect the frequency of electric field pulses, leading to different pulse polarity characteristics.

特高压GIS断路器VFTO辐射电场的测量
采用光纤测量系统测量了1100kV和550kV GIS断路器开关产生的辐射电场。分析了辐射场的波形特性和频率范围。结果表明，1100kVGIS断路器动作产生的辐射场幅值可达0.78kV/m, 550kVGIS断路器动作产生的辐射场幅值可达0.13kV/m。1100kV GIS的频率范围为20MHz ~ 100MHz，高于550kV GIS的0 ~ 5mhz频率范围。此外，不同类型的测试会影响电场脉冲的频率，从而导致不同的脉冲极性特性。
