110kV以上电压等级变电站避雷针折线法与滚球法保护半径对比分析

Comparative Analysis on Protection Radius of Lightning Rod Folding Method and Rolling Ball Method in Substation with Voltage Above 110 kV

根据国家相关规范的要求,探讨了变电站采用折线法和滚球法对变电站一次进线及室外电气设备防直击雷保护的差距,可为电力系统的防雷减灾工作提供科学依据。

According to the requirements of relevant national standards,the protection gap against direct lightning of primary incoming lines and outdoor electrical equipments in substation were discussed by using the folding line method and the rolling ball method,It can provide a scientific basis for the lightning protection and disaster reduction of power systems.
