摘要
针对平顶山矿区大多处于丘陵地段、雷电活动较为频繁,雷电对平顶山矿区6kV线路造成了很大危害的实际情况,平顶山煤业集团研究设计了一套6 kV线路防雷技术,对此套6 kV线路防雷技术杆塔进行了校验和耐张塔防雷计算与分析。给出了运行效果。
A set of 6 kV power line anti-lightning technology is developed by Pingdingshan Coal Group for use in Pingdingshan coal mine area which is mainly hilly terrain dominated by seasonal thunderstorms that do great harms to the 6 kV power transmission lines in the local coal mine area.On the basis of calibration of the lightning prevention poles,calculation and analysis of the tension poles for the lightning prevention poles plus the utilization of the system over a certain period of time,it becomes known that the application of this 6 kV power line lightning prevention technology diminishes the occurrences of lightning strokes to the power line.
