农村排灌泵站鼠笼式异步电动机的起动方式探讨

Discussion on the Starting Method for Squirrel-caged Electrical Motor Used in Rural Drainage and Irrigation Pump Station

农村排灌泵站鼠笼式异步电动机的起动方式建议采用全电压起动,以前认为起动电流大就不敢采用全电压起动的看法是不全面的。本文所举的算例可以看出,在条件允许的前提下,农村排灌泵站鼠笼式异步电动机采用全电压起动比降压起动有利。

Total voltage starting for the squirrel-caged electrical motor is suggested and in the before it was not completely correct to apply total voltage starting due to large starting current From the calculation examples in the paper, under allowance of precondi-tions, it is favourable to adopt total voltage starting than voltage reduction starting.
