摘要
本文旨在探讨一套具有较高性能价格比的低压电动机微机保护方案。文中讨论了用单片微机实现保护的主要原理;介绍了保护系统的硬软件设计。试验结果表明:保护方案可行,具有结构简单,性能良好等特点。
This paper aims to approach the microcomputer protection scheme of a low-tension motor with high-propertycost ratio. The chief working principle of protection by a single-chip microcomputer is discussed. The hardware and software designs of protection system are also introduced. The testing results indicate that the protection scheme is feasible and is Possessed of the features of simple structure and satisfactory performance, etc.
