摘要
Y-△起动是三相异步电动机常用的一种降压起动方法,但电路存在一些不完善的地方,使电路的运行状态不好,主要论述了对Y-△起动主电路的3点改进意见和防止转换过程中电源短路的措施,使Y-△起动电路更加完善、更加实用,对传统的Y-△起动器的改造有一定的指导作用。
"Y-△" starts is one of comment methods of triphase asynchronous motor. But the usual circuitry makes running state badly. Put forward consummate scheme to improvement the "Y-△" starting circuitry, to make the circuitry perfect and practical. At the same time, the methods is a guidanceof re - creation for traditional starts.
