分析了氧化锌避雷器在基波电压作用下,基波电压与阻性泄漏电流3次谐波分量间的关系。通过电场传感器获取线路基波和3次谐波电压信号,用数字信号处理技术分析氧化锌避雷器的全电流,提出了计算氧化锌避雷器阻性泄漏电流的新方法。仿真计算表明该法可较好地补偿氧化锌避雷器容性电流的基波和3次谐波分量。
Through electrical field transducer taking the line voltage signal, based on analyzing the relation of first harmonic current wave shape and third harmonic current wave shape of MOA under first harmonic voltage, making use of DSP technology, this paper put forwards a new method of calculating the first harmonic current and the third harmonic current of MOA＇s capacitive accurately.
