TYDZ-750KVA/0.4KV/0~10.5KV Contact Type Voltage Regulator

Mode: TYDZ-750KVA/0.4KV/0~10.5KV
Single phase           Frequency: 50Hz          Cooling methods: ONAN
Rated Capacity: 750kVA                                Rated Output Voltage: 0~10.5kV
Regulating methods: Motor drive                 Rated Output Current: 0~71.4A
Rated Input Voltage: 0.4kV                            Aberration Ration of Waveform: ≤3%
Rated Input Current: 1875A                          Starting Voltage ≤1%
Short-circuit Impedance:≤7.5%(in range of 50%~100%, impedance is being linearity)
Mode of Regulation: electrical drive Operation Time:5 min on, 30 min off, 20 cycles per day
Short-circuit capability: When test transformer discharge to the test object via damping resistance under transient state, short-circuit current reach 2 times of rated value. The discharge last 8 circle will no damage regulator’s winding or mechanical distortion.
Insulation Level: 20kV/1min (low voltage winding to earth)
                              5kV/1min (high voltage terminal to ground)
Overload capability: 1.2IH 30min, 1.4IH 15min, 1.6IH 5min.
Product structure: 1. There are upper and lower position limited, oil drain valve, oil level indicator
                                 2. Regulating unit and raise voltage raising units are set together.
