Circulating water pump motor is an important electrical equipment in thermal power plant

runs in a long period of time with the unit. It is one of the most important and critical equipment in power plants. It has great influence on the "power consumption rate" of technical and economic indexes of thermal power plants. The original circulating water pump motor operates in the way of power frequency operation

which can not be adjusted according to the demand of water

and the power consumption rate of the plant is high. Based on years of study and understanding of the use of motor

it is decided to transform its operation mode and transform the power frequency operation into frequency conversion operation. After retrofit

the starting current of the circulating water pump motor has decreased

and the power consumption rate has also decreased compared with that of the previous year.
