摘要
阐述基于ETAP软件,分析影响电动机动态起动的各种因素,包括电源变压器容量、阻抗、系统短路容量以及起动方式.分析表明,变压器容量越大阻抗越小,电动机端电压越高起动电流越大,越利于电动机启动,并提出一种判定电动机动态起动成功的判据.
Abstract
This paper expounds the analysis of various factors that affect the dynamic starting of electric motors based on ETAP software,including power transformer capacity,impedance,system short-circuit capacity,and starting method.Analysis shows that the larger the transformer capacity,the smaller the impedance,and the higher the motor terminal voltage,the greater the starting current,which is more conducive to motor starting.A criterion is proposed to determine the success of dynamic starting of the motor.
