摘要
雷电易对煤矿电力系统造成侵害,在变电所和地面电气设备上布置和安装防雷设施具有重要意义。按照被保护范围不同,分别对变电所场地、线路、变压器、主控微机和监控设备的防雷措施进行了探讨和研究;并结合实际工作经验,对所有防雷设施的防雷原理、配置必要性、设计要点等内容进行了总结,对煤矿企业的电力系统可靠性改造工程具有借鉴意义。
Thunder and lightning can easily couse damage to the power system of coal mines,and it is of great significance to arrange and install lightning protection facilities in substations and ground electrical equipment.According to the protection scope,the lightning protection measures of the substation site,circuit,transformer,main control computer and monitoring equipment were discussed and researched.Combining actual work experience,it summarizes the lightning protection principle,configuration necessity,and design essentials of all lightning protection facilities,which can be used as a reference for the power system reliability transformation project of coal mine enterprises.
