针对夏季机车主发电机机体过热多次报票以及电机架修时最终烘烤温度不够细化等现象,从热击穿理论分析入手,逐步介绍了材料绝缘等级的概念、分类及在电机上的具体应用,又通过热寿命分析以及了解的有关信息,最终界定了温度标准,在辅以相应措施后,取得了良好效果。 Aiming at the phenomenon of overheating of the main generator body of summer locomotive and the final temperature of baking when the motor frame is repaired, the concept of thermal insulation breakdown is introduced, and the concept of insulation level of material is introduced step by step. Specific application, through the hot life analysis and understanding of the relevant information, the final definition of the temperature standard, supplemented by the corresponding measures, and achieved good results.
