摘要
对低压三相异步电机的几种启动保护方案做了简单介绍,举例分析了几种启动保护方案的功能特点、应用场合、启动或过电流反时限特性曲线以及发展方向,并提出相关见解,以与设计同仁探讨。
This paper briefly introduces several starting protection schemes of low-voltage three-phase induction motors,analyzes the functional characteristics,application occasions,starting or over-current inverse time characteristic curve as well as development direction of these schemes with examples,and puts forward relevant opinions for discussion with design colleagues.
