摘要
三相异步电动机的启动,是《电工学》教学和实验的重点内容。文章分析了传统降压启动方法的缺点和现代软启动方法的优点。面对当前工业应用中后者已广泛替代前者的实际情况,建议改革有关的教学与实验内容。
Starting the three - phase asynchronous motor is important in the teaching and experiment Electrotechnology. This text analyzed disadvantages in the traditional start method with reduced - voltage and the advantages in modern soft - starting method. At present, the former method has been widety replaced by the latter in the actual application, so the author suggests that relevant teaching and experment content be reformed.
