Product Content Description:

Liquid resistance slip ring motor soft starter

 

 

 

 1)  Range of appication

     It is applicable to the heavy load smooth soft starting of coiling AC asynchronous motor that is of three phase AC 50Hz, rated operation voltage of 380V~10KV, rated power of 5kW~10000kW, especially in industrial and mining establishments with unstable or low voltage..

 

2)  Operating principle

     Special made electrolyte is put in the rotor loop of the controlled coil motor as the resistor, and by adjusting the density of the electrolyte and the distance between the two plate electrodes to ensure that the input resistance can meet the requirements of the motor's mechanic characteristics in the starting process, so as to make the motor rise speed equally with maxinum starting torque and minimum starting current, and to make  a smooth starting. When starting is over, the electric switch shorts the rotor loop.

 

3) Main performance characteristics:

    Soft starting, small starting current:  Iq1.3 Ie(A);

    Reduces motor starting temperature rise, effecively lengthend the motor's service life;

    Smooth starting, no shock to the mechanic equipments.

    Can make continuous starting for 5~10 times, starting performance is better than frequency sensitive starter;

    Low requirement for the power grid, no harmonic wave to affect the power grid;

    Structure is reliable, simple, convenient for installation and mintenance;

    Good uniformity , allicable to coiling motor soft starting under ny load situation, specially suitable for heavy load starting;

    Has multiple protection function like starting overtime, over stroke and over temperature;

    When used in North cold area, the equipment is equpped with the self-heating function.

 

4) Main techincal parameters:

    Starting initial current: Iq1.3 Ie(A);

    Startign time : 10~60s, presetting, adjustable on site;

    Starting times: continuous starting 5~10 times;

    Normal operation temperature of electro hydraulic: 5~70°C;

    Shell protection grade: IP20, IP30

 

 

5) Standards conformity:

    Low voltage switchgear and controlgear GB7521.1-1997 IEC439-1:1992

    WYQ liquid resistor starter  Q/XWZ2-200

 

6) Working conditions:

    Enviromental temperature: -40~50°C;

    Relative humidity: 90%;

    Absolute alititude: 200m (when altitude is above 2000m, it shall be specially designed according to the specific working conditions);

   Ground gradient shall not exceed 5°;

   Installation places shall be free of the risks of fire, explosion, chemical erosion and excessive vibration.
