Description | ||||
Liquid resistance soft starter is used for power ratings up to 20MW and voltage up to 10KV squirrel cage induction motor. | ||||
Working principle | ||||
This liquid resistance soft starter is used with the squirrel cage induction motor's stator windings. During the start-up period, the current passes through them and casuses a voltage drop, which allows a reduced voltage to the motor's stator windings. The current through the electrolyte causes it's temperature to rise and resistance to drop, and thus reduces the voltage drop. Gradually the voltage applied to the stator windings builds up until it almost reaches the rated voltage. At this stage the residual electrolyte can be totally cut off from the circuit with the help of a shorting contactor. | ||||
Performance and features | ||||
1. Small starting current, which is about 2.5 ~ 3.5 times of rated current. | ||||
2. It can start continuously for 2 ~ 3 times. | ||||
3. Starting is smooth, mechanical stress impact is little. Motors and driving machineries can be protected effectively. | ||||
4. No harmonic generated during or after starting process. | ||||
5. The simple and reliable structure. Automatic operation, easy install and maintenance. | ||||
6. This liquid resistance soft starter works with switchgear as a controlgear assembly. | ||||
Service condition | ||||
1. Ambient temperature: -10℃ ~ +40℃. | ||||
2. Relative humidity: no more than 85%. | ||||
3. Altitude: no more than 2000m. | ||||
4. Installation site: Vertical inclination shall be no more than 5 degree. No fire hazard, explosion risk, conductive dust, corrosive gas and strong vibration exist. | ||||
Applications | ||||
The liquid resistance soft starter has been specifically designed for controlling starting of high voltage squirrel cage induction motors in arduous applications in a variety of industries such as metallurgy, oil, chemical, water conservancy, coal, automobile, etc. | ||||
