TDGZ-450KVA/0.4KV/0~0.42KV Contact Type Voltage Regulator

Mode: TDGZ-450KVA/0.4KV/0~0.42KV
Single phase         Frequency: 50Hz         Rated Capacity: 450kVA
Rated Input Voltage: 0.4kV (Line to line voltage)
Rated Input Current: 1125A                      Rated Output Current: 0~1071.4A
Rated Output Voltage: 0~0.42kV             Aberration Ration of Waveform: ≤3%
Starting Voltage ≤1 %
Short-circuit Impedance:≤7.5%(in range of 50%~100%,impedance is being linearity)
Cooling: ONAN Noise level: <65dB (Measured in one meter)
Mode of Regulation: electrical drive
Operation Time: working for 60 min under rated voltage and current
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.
