摘　　要：接地装置的状况直接关系到电力系统的安全运行,科学合理的测试接地装置的特性参数对准确评估其状况十分重要。本文采用移动式小功率冲击电流发生器对攀钢电动鼓风站地网进行全面的现场测试,鉴于该站地网及防雷的缺陷,结合现有的实际情况研究了整改方法。针对目前地网评估涵盖新技术、新观念不够,本文提出的方法能有效地给接地网评估与改造提供参考。The status of grounding device is directly related to the safe operation of power system. Testing the characteristic parameters of grounding device scientifically and directly is very important to accurately assess the situation.This paper does the field test comprehensively with a mobile impulse current generator at Pangang electric blower station,according to the defects of the grounding grid and lighting protection,studies the rectification methods based on the actual situation.Due to the evaluation of grounding grid is not enough at present,the proposed methods in this article can provide reference for the evaluation and reform of grounding grid.
