Dyq4 Series H.v. Squirrel-cage Motor Liquid Resistor Soft Starter

. DYQ4series liquid resistor starter can induce the impact which isbrought to motor starting current on power system, and improve thestart smoothness with equipment by voltage-reduced starting by wayof liquid resistance. It can protect the motor avoid harm byover-load, phase failure, short circuit etc. It is the prefectstarting production instead of auto-induction voltage-reducedstarter.
The deviceis composed of resistor, high-voltage soft start controller,isolating cabinet, changeover cabinet and star point controller. Wesupply in full sets. The device can start motor and play aprotected action on motor start process, when connect it in motorstart circuit.
??? This resistor is composed of three phase balancing resistorwhich have negative temperature characteristic, when the current ispast through resistor, the temperature of resistor graduallyincrease and its resistance gradually decrease, then the terminalvoltage of motor gradually raise and the start torque graduallyincrease, so the motor can start smoothly and the start current canbe decreased.
