TYCZ 400KVA/10KV/0~10.5KV Cylinder Type Voltage Regulator

Mode: TYCZ 400KVA/10KV/0~10.5KV
Single phase, 50 Hz                      Voltage regulating way: electrical drive
Cooling: ONAN                               Rated capacity: 400KVA
Rated voltage: input voltage: 0.4KV   output voltage: 0~10.5KV
Rated current: input current: 40A        output current: 0~38.1A
Impedance voltage: ≤7% (regulating in the range of 50%-100%)
Starting voltage: ≤1%                            Boost Rate: 0 ~2kV/ s adjustable
Waveform distortion: ≤3%                    Noise level: ≤60db
Regulation accuracy: ± 1%                  Insulation level: 20KV/ 1min
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.
