TYDZ-100kVA/0.4kV/0~0.42kV Contact Type Voltage Regulator

Mode: TYDZ-100kVA/0.4kV/0~0.42kV
Single phase        Rated frequency: 50Hz       Rated Capacity: 100kVA
Voltage adjusting methods: electrical drive (single phase DC motor adjusting)
Rated Input Voltage: 0.4kV                               Rated Output Voltage:0~0.42kV
Rated Input Current: 250A                                Rated Output Current: 0~238.1A
Aberration Ration of Waveform: ≤3%
Short-circuit ability: continuous discharge 5 cycle do not cause any damage on the regulate winding.
Cooling: ONAN
Working time: 1hour on; transformer winding temperature raise ≤65K, oil surface temperature raise ≤55K, external surface temperature raise ≤30K.
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.
