摘    要:在总结现有的杆塔冲击接地电阻的计算测量方法的基础上,研制了便携式杆塔冲击接地电阻测量系统.它首先向接地体注入波头较缓、幅值较低的冲击电流,接着采集接地体的电压与电流信号,经滤波后再换算到标准雷电流下求出其电压响应,最后求出冲击接地电阻.实验室测试结果与传统的冲击接地电阻测量方法对比表明本系统测量方便且可信度高.

Abstract:A portable test method for impulse grounding resistance is proposed, on base of analyzing the existing calculation and measurement of tower impulse grounding resistanceo The principle of the measurement, the structure of hardware, the implementation of software and measured results are introduced in this paper. After filling the slow wave head and low value dash current into the grounding network, it collects the voltage signal and the current signal of the grounding network. By transform computation method after filtering, it gets the response voltage under the lightning current and works out the impulse grounding resistance. The test results of impulse grounding resistance on the contrast of traditional measurement show that the degree of belief is high and it is convenient for the measure of impulse grounding resistance.
Keywords:tower  impulse grounding resistance  measurement  convolution calculation
