摘　　要：建筑电气设计中对电动机类设备的启动主要考虑的是启动特性,既能保证电动机在负载要求的起动特性下平滑起动,又能降低对电网的冲击。文章通过对电动机启动功耗的分析论证了全压启动方式的节能特性,从节能角度进一步的证明了全压启动的优点。In electric design for starting electric motors the main consideration is its starting feature,it not only should ensure smooth start under the loading condition,but also can reduce its impact on the qrid.This paper expressed the energy efficiency feature of ling starting mode through analysing the starting power consumption of electric motor and the advangtage of line starting from the oiew pounf of energy efficency.

关 键 词：全压启动 空载启动 能耗起动
