TYDZ-350kVA/0.4kV/0~0.42kV Contact type regulator

Mode: TYDZ- 350kVA/0.4kV/0~0.420kV
Single phase         Frequency: 50Hz           Rated Capacity: 350kVA
Voltage adjusting methods: electrical drive (DC motor adjusting)
Rated Input Voltage: 0.4kV                           Rated Output Current: 833.3A
Rated Input Current: 875A                            Aberration Ration of Waveform: ≤3%
Rated Output Voltage:0~0.42kV                  Starting Voltage ≤1.5%
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.
