TYDZ 90KVA/0.38kV/0~0.65kV Contact Type Voltage Regulator

Mode: TYDZ 90KVA/0.38kV/0~0.65kV
Single phase      Frequency: 50Hz          Rated Capacity: 90kVA
Voltage adjusting methods: electrical drive (single phase DC motor adjusting)
Rated Input Voltage: 0.38kV                   Rated Output Voltage:0~0.65kV
Rated Input Current: 236A                      Regulating lower range <1%, upper range >95%;                
Aberration Ration of Waveform: ≤3%
Short circuit impedance <=7% (in range of 50% -100%, impedance is linear.)
Overvoltage capability: one hour on @ rated voltage and rated current; intermittent running @2/3rated voltage and 2/3rated current.
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.
