TYDZ-80kVA/0.415kV/0~0.42kV Contact Type Voltage Regulator

Mode: TYDZ-80kVA/0.415kV/0~0.42kV
Single phase         Frequency: 50Hz         Rated Capacity: 80kVA
Voltage adjusting methods: electrical drive (single phase DC motor adjusting)
Rated Input Voltage: 0.415kV                   Rated Output Voltage:0~0.42kV
Rated Input Current: 193A                         Aberration Ration of Waveform: ≤3%
Starting Voltage ≤1.5%
Short-circuit ability: continuous discharge 5 cycle do not cause any damage on the regulate winding
Cooling: ONAN
Working time: working 60 min under 100%UH,100%IH; 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.
