Wgq8 Series Of Intelligent Solid Soft Starter

WGQ8 series of intelligent soft starter
Range of application and typical application
It is applicable to the load smooth soft starting of cage model motor that is of three phase AC 50Hz, rated operation power of 5.5KW~500KW
Pump：with the pump control function, reduces pump current water hammer brought about by the liquid current impaction at starting and stopping, and saves the maintenance cost of the system;
Ball mill：with voltage slope starting, reduces the wear and tear of the gear torque and the work load of maintenance and lengthens the service life;
Fan：the solid soft starter replaces the traditional starter, reduces wear and tear and mechanical shock;
Compressor：using current limiting, to realize smooth starting and lower the motor temperature rise;
Crusher：locked rotor protection and quick protection make it possible to avoid over-heating and burning of motor caused by mechanical faults and block;
Conveying machinery：soft starting and soft stopping control realize the smooth and gradual starting process and smooth slowing stopping, thus avoiding damages caused to meterials and equipments by shocks.
Operating principle and performance characteristics
WGQ8 intelligent soft starter adopts three pairs of parallel thyristors put in the stator loop of motor, and make use of switch function of thyristor to control its touching angle with microcontroller, so as to control input voltage of the motor on the purpose of soft starting.
