摘　　要：主要阐述传统Y-△起动接线的不足,通过改进接线方式,实现了Y接起动时降低流过KY接触器主触点的电流,并解决了因各种原因造成电动机Y接法所不能转换成△接,从而保证电动机安全、可靠的运行。Through improving connection method, the reduced current on the main contacts of KY contactor in cose of Y connection stutas is realized. Also, the problem that Y connection fails to convert into △ connection due to some causes is solved, thus, to ensure the safe and reliable openation of motors.
