摘　　要：针对宝钛集团宽厚板材料公司的3 300 mm轧机发电机组换向不良的问题,从电磁理论、机械原理、电机负载及工作环境等方面分析了电机火花产生的原因,通过对电机、换向器、电路等逐项检测,采取了换向器打磨及换向器的表面处理等措施维修机组,检修后机组运行效果良好,发电机组火花未超过1级标准。To solve the reversing fault of generator set in 3 300 mm rolling mill of Wide and Thick Steel Plate Company of Baotai Group Co. , Ltd. , the reason that the generator produces sparks analyzed in combination with electromagnetic theory, macinery principle, generator load and operating environment. The solutions of polishing and processing the reverser surface were adopted after the generator, reverser and circuit were cheched. The overhauled generator set works quite well. Its spark is coincident with Class 1 Standard.
