一种新型异步电动机综合保护的研究

Research that a kind of new-type asynchronous motor protects synthetically

本文针对目前异步电动机常见故障及存在问题,分析了电机各类常见故障的特点,提出一种基于对称分量法及暂态波形鉴别的保护算法,利用半波积分完成启动与故障判别,开发了一种微机式综合保护装置,构成了一种功能强、动作快、可靠性高的异步电机综合保护装置。

This text has analysed the characteristics of all kinds of common troubles of the electrical machinery to the common trouble of the asynchronous motor and problem of existing at present, propose a kind of protection algorithm distinguished on the basis of symmetrical weight method and transient wave Differentiation, utilize half a wave of total marks to solve starting and differentiating with the trouble , has developed a kind of computer-based comprehensive protector, form a kind of function strongly, the fast , asynchronous electrical machinery comprehensive protector with high dependability.
