摘　　要：对一款输出交流电压为1 346 V的牵引发电机汇流环绝缘结构进行了改进,并对配套线棒的介质损耗、击穿电压等参数进行了实际验证,结果表明改进后汇流环绝缘结构简单、实用,并能满足电机使用要求。Improvement of insulation construction of the stator slip rings of a traction generators outputting AC 1345V was done. The laboratory tests on the bars used into the stator slip rings such as dielectric loss factor and breakdown voltage were performed. The tested result proved the improved stator slip rings with the advantages of simple construction, practical operation to meet with the operational requirement of the motor.
