YQR Liquid State Soft Starter for Slip-ring Motor /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.
