TYCZ 125KVA/0.38KV/0~3.3KV Cylinder Type Voltage Regulator

Mode: TYCZ 125KVA/0.38KV/0~3.3KV
Single phase, 50Hz                                 Voltage regulating way: electrical drive
Cooling: ONAN                                         Rated capacity: 125KVA
Rated voltage: input voltage: 0.38KV   output voltage: 0~3.3KV
Rated current: input current: 329A        output current: 0~38A
Impedance voltage: ≤7% (regulating in the range of 50%-100%)
Starting voltage: ≤1%                              Waveform distortion: ≤3%               Noise level: ≤60db
Voltage regulating way: Electrical drive (single phase DC motor), with upper and lower limit function to avoid faults caused by voltage regulating motor reversed;
Working time: working for 60 min under 100% rated voltage and current
Over current ability: working for 60 min under 120% rated current; 30 min under 140% rated current; 5 min under 160% rated current;
Short circuit ability: Under temporary capacity when output side of test transformer discharge to test object by protecting resistor, short circuit current is more than 2 times output. Discharging time lasting for 8 wave cycles should not cause any heat damage and mechanical distortion to regulator winding.
Structure: equip with upper and lower limit function, oil drain valve and oil indicator;
