TYDZ 300kVA/0.4kV/0~0.42kV Contact type regulator

Mode: TYDZ 300kVA/0.4kV/0~0.42kV
Single phase       Frequency: 50Hz          Rated Capacity: 300kVA
Voltage adjusting methods: electrical drive (DC motor adjusting)
Rated Input Voltage: 0.4kV                        Rated Output Current: 714.3A
Rated Input Current: 750A                         Aberration Ration of Waveform: ≤3%
Rated Output Voltage:0~0.42kV               Starting Voltage ≤1.5%
Short-circuit ability: continuous discharge 5 cycles does not cause 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.
