摘　　要：介绍一种由单片机控制的三相异步电动机Y/D转换节能保护器。该节能保护器可克服传统Y/D转换节能器在Y/D转换点发生频繁转换的现象，同时还具有D/Y降压起动功能及电动机断相、过载等保护功能。This paper introduces an energy saving protector used for the Y/D transformer of three phase asynchronous motor. This instrument not only could overcome the traditional shortcoming of frequent transferring in the Y/D transforming point, but also could start motor with D/Y step down and protect motor from broken phase and overload.
