TYDZ-350kVA/3.3kV/0~6.3kV Contact type regulator

Mode: TYDZ-350kVA/3.3kV/0~6.3kV
Single phase          Frequency: 60Hz               Rated Capacity: 350kVA
Voltage adjusting methods: electrical drive  (DC motor adjusting )
Rated Input Voltage: 3.3kV                                Rated Output Current: 0~55.5A
Rated Input Current: 106A                                 Aberration Ration of Waveform: ≤3%          
Rated Output Voltage:0~6.3kV                         Starting Voltage ≤1%
Impedance voltage: ≤7% (adjusting in the range of 50%~100%, impedance is linear )
Short-circuit ability: continuous discharge 8 cycles not causes any damage on the regulator winding.
Cooling: ONAN                                                    Working time: 1 hour on.
Over-load capability: 60min @120%rated current; 30min@140% rated current; 5min@160%rated current.
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.
