Slip-ring Motor Starter uses aqueous solution of special medium as resistance. Plate is introduced

                  Slip-ring Motor Starter summary

   YQR  Liquid Resistance Starter for Slip-ring Motor is a new generation starting controller researched and developed to further improve starting performance of medium and large coil-winding asynchronous motor. By connecting a liquid resistance in rotor loop of motor controlled, which automatically runs upon starting of the motor, and disconnects automatically, steplessly and continuously as scheduled, the following deficiency was overcome: impulse current of obsolete starting controllers such as frequency sensitive rheostat, oil immersing rheostat and cast iron rheostat is strong, and starting process is not desirable. In this case, motor starts under ideal starting current and speed up evenly. The starting controller has significant advantages in protection of motors, electrical devices, power grid and conservation of energy. The controllers design is elaborate in terms of starting, stopping, protecting against failure, communicating, alarming and displayer. In comparison with obsolete starters, it boast itself of such characteristics, as high level of automation, less starting current (usually being less than 1.3 times of rated current), less electrical and mechanical shock, and it is especially suitable for starting under heavy load. Even in the event that power grid voltage is low, it can start successfully. It reduces capacity of transformer. At present it is a most desirable starting controller for ball mill, hoister, crusher, compressor, fan and water pump under heavy load.


II. Performance and features

1.   It is superior to frequency sensitive rheostat, oil immersing rheostat and cast iron rheostat

      in terms of performance.

2.   Its tarting current is less, which is less than 1.3 times of rated current of motors.

3.   It can start for 5-10 times in succession.

4.   ts starting process is smooth: It has no shock of mechanical stress on devices, thus life

      of  machineries and motors are prolonged.

5.   t can start under low voltage. It can start successfully in 5.5 KV for motors of 6 KV 340 V

      andinfor motors of 380 V.

6.   It is simple and reliable in structure. All operations are in automation. It is     

      asy in installation and maintenance.
