摘要
阐述了电动机启动所需的条件:电网应具备的条件;电动机不同启动方式的特点,电动机负载特性。介绍了全压及降压启动时(频率不变),发电机组启动电动机最大容量的计算:按启动转矩校验;按电动机启动容量计算。
In this paper, the necessary conditions for the starting of electric motor, the necessary conditions for electric network, the features for different starting modes and the load characteristics of electric motors have been expounded. The calculating method for the maximum capacity of the starting motor of the generator set at full voltage and voltage step-down frequency do not change has been introduced: verification as per starting torque and calculation on the basis of the motor starting capacity.
