TYDZ 70kVA/0.38kV/0~0.420kV Contact Type Voltage Regulator

Mode: TYDZ 70kVA/0.38kV/0~0.420kV
Single phase      Frequency: 50Hz        Rated Capacity: 66kVA
Voltage adjusting methods: electrical drive (DC motor adjusting)
Rated Input Voltage: 0.38kV                  Aberration Ration of Waveform: ≤3%
Rated Output Voltage:0~0.420kV         Starting Voltage ≤1.5%
Impedance voltage: ≤7.5% (adjusting in the range of 50% ~100%, impedance is linear )
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.
