摘　　要：相关设计手册电动机起动母线电压及端电压相对值计算公式、起动电流计算公式,笔者经过研究推演发现表达不完整或有误。本文将自耦变压器降压起动及变压器—电动机组全压起动计算过程进行推演展示。Through study and deduction, the author finds out some incomplete expression and mistakes in formulas that calculate the relative values of busbar voltage and terminal voltage as well as the starting current during motor starting in relevant design handbooks. Therefore, the article demonstrates the deductive process of the calculation of self-couple transformer reduced voltage starting and transformer- motor unit full voltage starting.

关 键 词：自耦变压器 降压起动 变压器一电动机组 全压起动 电动机 起动母线电压相对值 起动电动机端电压相对值:起动电流
