摘　　要：通过对电力交流接地网损坏原因进行调研发现,接地网现场出现的主要问题是接地网腐蚀、接地引下线截面偏小以及接地体之间连接不良,而出现这样问题的关键环节却在设计(标准)和施工质量管理上。文章对现场暴露的接地网腐蚀、接地引下线截面偏小和接地体之间连接不良3个方面主要技术原因进行了技术分析。指出,要提高接地网的可靠性,就应制定或修订相关标准。According to the investigation of damaging reasons for AC electric power grounding network, the major problems occurred on - the - spot of grounding network are corrosion of grounding network, little section of grounding down lead and bad connection between grounding bodies, and the crucial link for such problems is on management of design and construction quality. The technical a-nalysis for the reasons from three aspects mentioned above was carried out. It is pointed out that the relative standards should be established or revised to raise the reliability of grounding network.
