摘要
针对江苏连云港郊区变压器的现场勘察情况,提出人工接地体技术方案。通过对地网形式设计的研究,结合物理降阻剂的使用,介绍了减小连云港山区配电变压器(以下简称配变)接地电阻的经验,运行表明经过降低接地电阻后,雷雨季节配变的故障率明显下降。
Artificial grounding electrode technology is proposed according to the on-the-spot survey of distribution transformers in mountain areas of Lianyungang. The paper introduces the experience of reducing ground resistances of distribution transformers in mountain areas of Lianyungang by way of research on formal design of ground grid, combined with usage of physical resistance-reduction additives. Performance shows that the fault ratio of distribution transformers during the thunderstorm season decreases obviously by the way of reducing ground resistances.
