摘要
为了防止雷电引起110kV供电线路跳闸、损坏,同时满足产能增加的需求,刘庄煤矿根据自身实际情况,对110kV变电站进行了环网改扩建设计,并对架空配电线路采取安装架空避雷线、氧化锌避雷器等防雷措施。变电站环网改扩建设计使整个供电线路在结构上形成了供电环网,即任何一路因雷击造成线路跳闸或损坏的供电线路都能通过供电环路对任一负载进行供电,从而解决了供电线路的可靠性问题。
In order to prevent trip and damage of 110 kV power supply line caused by thunder and meanwhile satisfy demand of production increase,reform and extension design of ring network of 110 kV substation of Liuzhuang Coal Mine was done,lightning protection measures of overhead distribution lines including overhead ground wire and zinc oxide arrester were adopted according to its actual situation.The reform and extension design of ring network make whole power lines form a ring network of power supply,namely,the ring network can ensure to supply any load by power supply loop when a power line happens trip or damage caused by thunder,so as to solve reliability problem of power supply lines.
