TYDZ 400kVA/3kV/0~3.3kV Contact type regulator

Mode: TYDZ 400kVA/3kV/0~3.3kV
Single phase      Frequency: 50Hz            Rated Capacity: 400kVA
Voltage adjusting methods: electrical drive (DC motor adjusting)
Rated Input Voltage: 3kV                          Rated Output Current: 121.2A
Rated Input Current: 133.3A                    Aberration Ration of Waveform: ≤3%
Rated Output Voltage: 0~3.3kV              Starting Voltage ≤1.5%
Allowed Operating Time: same with the reactor.
Short-circuit ability: continuous discharge 5 cycles does not cause any damage on the regulator winding.
Cooling: ONAN                                           Working time: 1 hour 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.
