Dry Type Voltage Regulating Transformer
The SCBZ9-315~2500 dry type voltage regulating transformer can be
used to regulate voltage manually or automatically. It is suitable
for use in occasions where highly stable voltage is required or
voltage fluctuates frequently and significantly.
The existing load transformers all adopt step voltage regulation.
For the voltage level of 10kV, the regulation range is -10% to +10%
of the rated voltage. There are generally nine levels. Voltage
regulation range can be designed according to user requirements,
but the maximum does not exceed 20% of the rated voltage.
1. Voltage regulating taps of the high voltage coil are set
according to the switch requirements. They are greater in number
than those of the ordinary transformers.
2. Since the voltage is regulated by adjusting the tap at present,
it is necessary to install an on-load tap changer for safe
3. The tap changer is attached with a controller. Through this
controller, voltage regulation operation can be completed. Manual
and automatic operation modes are optional.
