Description

Medium Voltage Magnetically Controlled Soft Starter

AC motors are widely applied in every field of national economic, when the motor starts directly, there are lots of problems, such as big starting current, violent impact on power grid and mechanical equipment, short service life of motor, which will generate high maintenance cost every year. Sinopak High voltage Magnetically controlled soft starter can reduce the voltage drop caused by direct starting motor, it will not affect the normal run of other equipment, and meanwhile, it can reduce the impact current of motor,because impact current will cause temperature rise of the motor, which result in motor insulation damage etc.

Sinopak High voltage magnetically controlled soft starter can start and stop at any time and improve working efficiency. 

 

 
 
 
 
 
 
 
 
 
 
 

Principle of Magnetic control Soft Starter

A high-voltage magnetic controlled soft starter is composed of inlet wires, switch and medium-voltage controlled reactor, motor and its load. A fail-safe secondary control system is composed of controller, three-phase full wave rectifier and high/low-voltage dual isolators. 

 
 
 
 
 

In the system of high-voltage magnetic control soft starter, closed-loop current control is achieved by acquiring primary loop current to adjust the low-voltage control coil so as to change the reactance value of high tension loop of the reactor, such that the motor may be started up smoothly.
