    Dry Type Voltage Regulating Transformer

    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.

    Features
    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 switching.
    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.
