I Product Name: Liquid motor starter
II Product Type: WYQ
III. Application
Our liquid motor starter is suitable for wound motor of 3-phase AC 50/60 Hz, rated working voltage is 380V-10kV, rated power is 75kW-10000kW, especially for the enterprises or grids whose voltage is unstable or very low.
IV Principle
Put the resistance which made by special electrolyte in the rotor loop of the wound motor, adjust the density of the electrolyte and the distance of the plate to make the resistance value meet the motor requirement in the starting process. So as to make the motor start smoothly with biggest starting torque and minimus starting current. When start finished, the electric switch short circuit the rator loop.
V. Main features:
1 Soft starting, low start current: Iq<le; 1.3Ie(A);
2 Reduce motor starting temperature rise, prolong the life span of motor
3 Smooth starting, no shock to the machines
4 Can make continuous start for 5-10 times
5 No harmonic wave to affect the power grid.
6 Reliable structure, easy to install and maintain;
7 Suitable for many kinds of load wound motor, especially for heavy load starting;
8 Multiple protection functions: Start overtime, over temperature etc.
9 When used in cold area, the equipment will be self-heated.
