摘　　要：由于鲁地拉电厂发电机转子磁极间引线绝缘套管破损导致转子磁极绝缘降低而出现转子接地故障频发,因此对故障情况进行调查、分析,研制出了一种新型转子极间引线绝缘套,彻底消除转子绝缘套频繁损坏的情况,并成功运用于1号、2号、3号、4号、5号机,并可全面向行业内采用同类型发电机转子机构的电厂推广应用。The insulation sleeve of rotor magnetic pole lead of generator in Ludila Power Plant is damaged,which leads to the reduction of rotor magnetic pole insulation and frequent rotor ground fault.Therefore,this paper investigates and analyses the fault condition and develops a new type of insulation sleeve for rotor interpole lead.It completely eliminates the frequent damage of rotor insulation sleeve and is successfully used in No.1,No.2,No.3,No.4 and No.5 units.It can be widely used in power plants with the same type of generator rotor mechanism in the industry.
