Hot-selling oil immersed transformer off load tap changer China Manufacturer Details

Product Description

The strip excitation-free Tap Changer has its flange and support plate fixed on the transformer box cover, and the tap changer operates on the transformer box cover to change the number of turns in the transformer winding and achieve the purpose of transformer voltage adjustment. When it is necessary to adjust the voltage, the transformer must be cut off from the network and placed in an excitation-free state before operating the tap changer.

The structure of off off-circuit tap changer consists of a drum, cage, strip, disc, and wedge. The fixed contact of the disc structure non-excitation switch is installed on the disc-shaped insulating part, and the moving contact rotates in the center of the disc to change the tapping. Disk switch is commonly used for neutral point voltage regulation of Y connection winding, three-phase structure, and the general voltage is not higher than 35kV.
