SCB on-load tap changer dry-type transformer
Description
● Introduction to the product
This product is composed of the transformer body and the on-load tap changer. The voltage can be increased or decreased through regulation when there are loads. Voltage can be regulated manually or automatically. Manual voltage regulation means the voltage is regulated to one certain value artificially within the tapping range of the product. Automatic voltage regulation means the automatic voltage regulator is regulated into one small range (usually referring to the value point required by the electrical equipment) within the product tapping range at first. When the output voltage is beyond this range (for example, the change in the power supply voltage or the change in the load cases a secondary voltage change), the automatic voltage regulator will automatically send signals to make the on-load tap changer automatically regulate the secondary voltage into the specified voltage range.
