Voltage-reduced Compensation Solid Soft Start Device

Our provided Voltage-Reduced Compensation Solid Soft Start Devices are applicable to large or medium-sized high voltage squirrel-cage AC asynchronous electric motors or asynchronously started high voltage synchronous electrical motors for the purpose of motor soft starting. The device can achieve small current and high magnetic torque when starting motor. Its starting performance is superior to the high voltage frequency converter for simple structure, exempting from maintenance and no harmonics and it is also an ideal substitute for all kinds of voltage-reduced starting products.
As an international initiator, the device adopts two patents with technology being first-rank in the nation.
The device can be applied to the soft starting of the 6,10kv large capacity electric machines with power below 50000kw.
Main Characteristics
1. The starting loop current is less than 1.5 times of the rated current of motor;
2. Voltage drop of power system can be set from 5% to 12% when starting;
3. Low request for grid capacity can reduce the installation capacity of Transformer, and reduce investment of equipments;
4. High starting torque, can meets the demands of different loads;
5. Can start continuously, high repetitive precision, no overvoltage during switch operation;
6. No harmonics, has very little influence on power quality, has low voltage drop, and no additional active power loss;
