TYDZ- 5kVA/0.224kV/0~0.25kV Contact type regulator

Mode: TYDZ- 5kVA/0.224kV/0~0.25kV
Single phase                                   Rated Input Voltage: 0.22kV
Frequency: 50Hz                           Rated Input Current: 22.7A
Rated Capacity: 5kVA                   Rated Output Voltage:0~0.25kV
Voltage adjusting methods: electrical drive (DC motor adjusting)
Rated Output Current: 20A         Aberration Ration of Waveform: ≤3%
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, short circuit current reach 2.5IH.
Over-load ability: 30mins at 1.2IH, 15mins at 1.4IH, 5mins at 1.6IH.
Cooling: ONAN                            Working time: 1 hour 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.
