TYDZ-80kVA/0.38kV/0~0.65kV Contact Type Voltage Regulator

Mode: TYDZ-80kVA/0.38kV/0~0.65kV
Single phase    Frequency: 50Hz     Rated Capacity: 80kVA
Voltage adjusting methods: electrical drive (DC motor adjusting)
Rated Input Voltage: 0.38kV            Rated Output Current: 123A
Rated Input Current: 210.5A            Aberration Ration of Waveform: ≤3%
Rated Output Voltage:0~0.65kV    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.
Over-load ability: 30mins at 1.2IH, 15mins at 1.4IH, 5mins at 1.6IH
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.
