TYDGZ-500kVA/10kV/0~10.5kV Contact Type Voltage Regulator

Mode: TYDGZ-500kVA/10kV/0~10.5kV
Single phase                      Frequency: 50Hz                  Rated Capacity: 500kVA                    
Voltage adjusting methods: electrical drive                  Rated Output Voltage:0~10.5kV
(single phase DC motor adjusting)                                 Rated output current: 0~47.6A
Rated Input Voltage: 10kV                                                Regulating lower range <1%, upper range >95%;
Rated Input Current: 50A                                                  Aberration Ration of Waveform: ≤3%
Short circuit impedance ≤7% (in range of 50% ~100%, impedance is linear.)
Overvoltage capability: 60min @ 120% rated output current; 30min @ 140% rated output current; 5min @160% rated output current.
Cooling: ONAN                                                                  Working time: 1hour on.
Note: include - magnetism oil surface indicator, servo motor driving device, position indicator with terminal contacts and protection contacts.
The symmetrical compensation and reversed polarity voltage regulation circuit is adopted so that output voltage of the regulator keeps smooth and linearity, and regulating speed can be set and to be very stable. The interlock between voltage regulator, control table and secondary switch are available.
