Series high-voltage cage motor soft starting device
Principle
Series high-voltage cage motor soft starting device
The principle of the series high-voltage cage motor soft starting device is to insert the starting voltage in series into the stator circuit of the high-voltage squirrel-cage (synchronous) motor. With the special water resistor and current limiting function, during the process of starting, the resistance of the water resistor automatically changes steplessly from large to small within the set time
, thereby increasing the voltage applied to the upper end of the motor stator. Gradually increase, when the motor speed is close to the rated speed, the water resistance is automatically cut off and put into full voltage operation, thereby achieving a low current and smooth soft start of the motor.
Series of high voltage cage motor soft starting devices
Performance characteristics
. The starting current of constant current soft start is several times the rated current, which reduces the heat of the motor and effectively extends the service life of the motor
. The starting is smooth and there is no impact, the starting voltage drop is within the limit, and the impact on the power grid is small
. It is not affected by grid voltage fluctuations and load changes, ensuring consistent starting success and continuous starts
. Equipped with complete alarm prompt function and motor protection function
. It has simple structure, automatic operation and convenient maintenance
. Use control or relay control to detect the starting current to achieve closed-loop control
