Slip-ring Motor soft starter /380v-20kv

Application
Applied to wound-rotor asynchronous motor overload smoothly soft start

are which three phase current 380V,660V,3KV,6KV,12KV, power rating

45~10000KW.

Working Principle
The controlled of wound-rotor asynchronous motor rotor loop in series

with the three-phase star connection liquid resistance, fluid

resistance with starting motor and automatic input, resistance will be

stepless reduced within predetermined time, close to zero automatic

excision, thus motor access rated current and maximum torque

circumstances no impact on the smooth start-up.

Perforamance and features
1.Low starting current and constantly, no impact on the grid;
2. The starting current is less than 1.3 times of rated current,it can

reduce the capacity of transformers
3. It can start under low voltage, power grid voltage can ensure motor

run normally,then starting smoothly
4. It can start for 5~10 times in succession
5. It smooth start up, little impact of mechanical stress, can protect

the motor and transmission machinery effectively
6. Applicable to heavy load start
7. Simple structure, convenient installation and maintenance, high

reliable
