摘　　要：分析了一起风力发电机组底部平台漏电现象的原因,得出了接地的电气汇流排与等电位环之间应有2根接地电缆进行连接,第一根接地线连接完毕后,连接第二根时搭接瞬间的放电现象属正常现象的结论。Based upon the analysis on the cause of electric leakage of platform at the bottom of a wind turbine,it is concluded that there should be two grounding cables between the grounded electrical busbar and the equipotential ring,and that upon the first grounding wire is connected,the discharge phenomenon at the moment of a second wire bonding is normal.
