浅谈异步电动机的电气保护装置

Superfacial View on the Electric Proctective Device of Asynchronous Generator

本文阐述了异步电动机的保护与控制关系,介绍了异步电动机的各种保护装置。指出不管采用何种保护装置,必须考虑过载保护装置与电动机、过载保护装置与短路保护装置的协调配合。

This article illustrates the relation between asynchronolus generators protection and control;introduces various kinds of protective devices. It points out that no matter what kind of protective device we use,we must consider the coordination between overload protective device and the generator,between overlaod protective device and short-circuit protective device.
