The DYQ3 series is used a special liquid resistor to be connected in series to the rotor circuit of large and medium slip ring motor, the liquid resistor get to work when the motor starting and it can automatic, stepless and continuous removal during the preset time, then the motor can start smoothly under ideal starting current condition. Eventually the motor can accelerate balanced. This plays an important role in protection of motor, electric equipment£¬power system and saving electricity. As well as the well-designed of system starting, stop, error protection, liaison and display, making the liquid resistor starter have high degree of automation, small starting current (less than 1.3 times for rated current in general), can start successfully when power system have low voltage, and reducing the capacity of transformer remarkably. So DYQ3 series liquid resistor starter is the most ideal starting equipment for heavy load device such as: ball crusher, hoister, compressor, blower and water pump etc.

KYN28-12 indoor metalclad withdrawable switchgear is designed to be complete distribution equipment with three-phase A.C. singe busbar and single busbar section system having a rated voltage of 3.6~12kV and rated frequency of 50Hz.The switchgear is mainly employed in receiving and distribution of power energy from the network as well as starting of large-sized HV motors. In addition, the switchgear is provided with controlling, protection and monitoring functions. The switchgear conforms to IEC 298, GB 3906, DL/T404-91 and other standards. The switchgear itself owns five prevention functions such as prevention of misoperation of circuit breakers, prevention of pushing or pulling truck with load, prevention of closing earth switch under voltage, prevention of supplying power when earth switch is at the earth position and prevention of entering the electrical separation zone by accident. The switchgear selects not only VS1 vacuum circuit breakers but also ABB made VD4 vacuum circuit breaders, thus recogninzed as power distribution equipment with excellent performance.
DYQ4 series liquid resistor starter is a new starter prepared for improving the starting property of high voltage squirrel-cage alternating current asynchronously motor. It can induce the impact which is brought to motor starting current on power system, and improve the start smoothness with equipment by voltage-reduced starting by way of liquid resistance. It can protect the motor avoid harm by over-load, phase failure, short circuit etc. It is the prefect starting production instead of auto-induction voltage-reduced starter.
The product is suitable for power plant, substation, industrial enterprise, etc. It takes a role of motor distribution, electromotor control in 50/60Hz, max working voltage 660V, max working current 3150A distribution system.
The product is high breaking capacity, perfect dynamic stable, reasonable structure, effective electric scheme, strong versatility, multi loops, save acreage, excellent appearance, high protection degree, convenient maintenance, secure and reliable.
