WLQ Series Of High Voltage Cage Model Motor Starter

Descripción del producto

Operating principles

Put special liquid resistor which can perform voltage division and current limiting into the motor stator loop, in the starting, liquid resistor’s resistance can automatically change from large to small within the set time, when it changes to zero, the liquid resistor is automatically cut off and the motor gets into operation.

Small starting current, 1.5~3.5 times of the motor’s rated current;

Smooth starting, no shock, guarantee for the reliable operation of power grid, effective protection motor and transmission gear and strengthens the equipments’ service life;

Continuous starting 5~7 times, starting performance is better than reactor starting and thermal alteration resistor starting;

With sound warning function and motor protection;

PLC control, reliability;

Simple structure, convenient maintenance, and low requirements for maintenance staff;

Aiming at different load conditions and different use occasions, rotary plate structure and shift-type structure with autonomous patent right were respectively developed to make it have wide adaptability.

In order to satisfy the special requirements of the occasion where the frequent starting happens, the frequent-starting type high voltage cage-shaped starter with autonomous patent right was developed to better overcome the disadvantage that the common high voltage cage-shaped starter cannot be started frequently.
