对灯泡贯流式发电机定转子扫膛事故的研究和改进意见

The Study and Improvement for the Contact Fault Between the Air Gap of the Stator and Rotor of the Bulb Tubular Hydrogenerators

根据电站中有关四个灯泡贯流式发电机多次发生定转子扫膛的事故及处理情况，结合贯流式电机与常规电机的许多不同之处，进行了全面深入的评述和分析研究，指出了影响贯流式电机安全运行的有关特殊结构问题和使用条件，提出在设计、制造和安装运行中需要特别注意的有关事项和改进意见。

ccording to the contact faults between the air gap of the bulb generators at four hydro power stations,and corresponding to some special construction problems of the bulb generator,this paper studies and discusses properly and carefully for the safe operation problem of the bulb generator,point out some neccesary special attention objects and improvement methods of design manufacture and operation of the bulb generator.
