异步电动机断相保护系统研究

Break-phase Egis of Asynchronous Electromotor

本文主要阐述了电动机断相运行给电动机造成的危害,并在分析对比常用的三种电动机保护优缺点的基础上,介绍了一种简易的适用范围较广、灵敏度较高,且具有节电功能的三相异步电动机保护的原理。

This articl elaborated the of motor fault running of losing phase. And in the advantages and disadvantages of three kinds of commonly used protecting motor based on, this paper introduces the protective principle of three phase asynchronous motor, which has many advantages,such as wide application, high sensitivity and power saving function.
