TYCZ 200KVA/0.4KV/0~6.3KV Cylinder Type Voltage Regulator

Mode: TYCZ 200KVA/0.4KV/0~6.3KV
Single phase, 50 Hz                                        Cooling: ONAN
Voltage regulating way: motor drive (single phase DC motor)
Rated capacity: 200KVA
Rated voltage: input voltage: 0.4KV   Output voltage: 0~6.3KV
Rated current: input current: 500A      Output current: 0~31.7A
Impedance voltage: ≤7.5% (in the range of 50%-100%)
Waveform distortion: ≤3%                 Starting voltage: ≤1%              Noise level: 60db
Insulation level: Primary winding to secondary winding and ground insulation: 5kv/1 min; secondary winding to primary winding and ground insulation: 20kv/ 1min;
Over current ability: working for 30min under 120% rated current; 15 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.
Working time: 15 min on, 15 min off, 8 cycles per day
Structure: equip with upper and lower limit function, oil drain valve and oil indicator;
