Abstract:For the power supply and distribution design of a single elevator,a systematic analysis is conducted from power selection to voltage drop verification of the power cable,three methods for calculating and selecting the power of the elevator tractor under different conditions are set out,the nameplate data of the elevator tractor is interpreted,and the equivalent power calculation of the elevator and the continuous current ⁃ carrying capacity of the power cable specified in the code,etc. are analyzed.

Key words:elevator;tractor;equivalent power;working mode;voltage deviation;voltage drop verification;permanent magnet synchronous motor;continuous current ⁃ carrying capacity

摘　要：针对单台电梯的供配电设计，从功率选择到供电线缆电压降校验作系统分析，提出3种不同条件下计算选择电梯曳引机功率的方法，解读电梯曳引机铭牌数据，分析电梯等效功率计算及规范条文中供电线缆连续工作载流量等。

关键词：电梯;曳引机;等效功率;工作制;电压偏差；电压降校验;永磁同步电动机；连续工作载流量
