TYDZ-300kVA/0.4kV/0~0.6kV Contact Type Voltage Regulator

Mode: TYDZ-300kVA/0.4kV/0~0.6kV
Single phase        Frequency: 50Hz       Rated Capacity: 300kVA
Voltage adjusting methods: electrical drive (DC motor adjusting )
Rated Input Voltage: 0.4kV                     Rated Output Current: 500A
Rated Input Current: 750A                      Aberration Ration of Waveform: ≤3%
Rated Output Voltage:0~0.6kV              Starting Voltage ≤1.5%
Impedance voltage: ≤7.5% (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: 1hour 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.
