摘　　要：近年来,各发电厂对自身厂用电损耗越来越关注,力争采用降低厂用电损耗的措施,从而降低投资和运行成本。某燃机电厂机械通风冷却塔电动机功率为200kW,按《火力发电厂厂用电设计技术规定》,当高压厂用电压为6kV 1级时,200kW左右的电动机可按工程实际情况选择电压等级。因此,对冷却塔电动机采用中压6kV还是低压380V进行研究比选,选择适合该燃机电厂的电动机电压等级,以达到降低投资及运行成本的目的。In recent years,power plants have become increasingly concerned about their own power consumption losses and strive to adopt measures to reduce power consumption losses,thereby reducing investment and operating costs.the power of the electric motor in the mechanical ventilation cooling tower of a certain gas turbine power plant is 200 kW.aAccording to the“Technical regulations for the Design of plant power Supply”,when the high-voltage plant voltage is 6 kV level 1,the voltage level of the 200 kW electric motor can be selected according to the actual engineering situation.therefore,a comparative study was conducted on whether to use medium voltage 6 kV or low voltage 380 V for the cooling tower motor,and the suitable motor voltage level for the gas turbine power plant was selected to achieve the goal of reducing investment and operating costs.
