摘要
以新型长寿命多针式垂直接地技术研究及实现为背景,基于尖端放电理论,设计了一套新型矿用接地系统,具有快速放电、增大泄流及小型化的特性,并成功应用于兖州矿用变电站接地系统。经验证,新型矿用接地系统降低了接地电阻,提高了矿用变电站的安全可靠性,解决了接地系统小型化的工程难题,为矿井接地技术的研究提供一定的参考。
Relying on new long-life multi-pin vertical grounding technology research and implementation as the background,is based on the theory of cutting-edge discharge theory, to design a new composite grounding system equipped with rapid discharge, increasing discharge and miniaturization. It is successfully applied to the grounding system of 110 kV substation for Yanzhou mine. It has been proving that the new mine grounding system has greatly reduced the grounding resistance and improved the safety and reliability of mine substation. The problem of miniaturization of grounding system is solved, which provides some reference for the research of mine grounding technology.
