摘要
根据DL/T 987—2005标准所推荐避雷器泄漏电流标准波形,设计了三次谐波分量和全泄漏电流结合的避雷器泄漏电流测量系统。整个系统通过电流传感器、电流电压转换电路、滤波电路、峰值电路实现对避雷器泄漏电流三次谐波分量和全泄漏电流分量波形处理。搭建了系统,并根据DL/T 987—2005标准所提供的误差试验方法对该系统进行校验,试验结果满足现场测试要求。
According to the standard waveform of lightning arrester leakage current recommended by 987-2005DL/T standard,this paper designs a leakage current measurement system,which based on the combination of the three harmonic components and the total leakage current.The whole system is based on the current sensor,current voltage conversion circuit,filter circuit,peak circuit to achieve the lightning arrester leakage current three harmonic component and the whole leakage current waveform processing.This paper set up the system,and test it according to the 987-2005DL/T standard‘s error test method.the test results meets with the acquirement of on-site measure.Therefore,the circuit designed in this paper can realize the measurement of leakage current of arrester.
