摘　　要：近年来新能源项目大规模投资建设,新能源项目的生产车间烧结炉、设备的电动机为主要能耗设备,如何降低能耗、提高能效、节约成本成为不可忽略的主题。目前,工业建筑中使用的电动机工作电压大多采用低压380 V,这一电压等级对于中小功率的较为合适。随着新能源项目投资规模扩大,电动机的功率达到上百甚至上千瓦,改为更高电压等级的电动机是否更有优势,本文对此展开分析。In recent years,new energy projects have been invested and constructed on a large scale.The sintering furnace in the production workshop of the new energy project and the motor of the equipment are the main energy consuming equipment.The theme of how to reduce energy consumption,improve energy efficiency and save costs cannot be ignored.At present,the working voltage of motors used in industrial buildings is mostly low voltage 380 V,which is suitable for small and medium power motors.With the expansion of the investment scale of new energy projects,the motor power has reached hundreds or even kilowatts.This paper analyzes whether it is more advantageous to change to a higher voltage motor.

关 键 词：供电方案 投资成本 电能损耗 建筑面积
