The BTK-110kV/220kV transformer neutral point accessory combination mainly includes the following related equipment: neutral point disconnect switch, discharge gap, zinc oxide lightning arrester, and current transformer for measuring discharge current. To ensure an aesthetically pleasing and convenient equipment arrangement, a separate T-shaped or portal-shaped bracket can be designed based on the user's equipment selection, integrating the neutral point disconnect switch, discharge gap, lightning arrester, and other neutral point accessory equipment into a single unit that facilitates on-site construction and installation. This transformer neutral point accessory combination equipment provides protection against lightning overvoltage, switching overvoltage, and temporary overvoltage at the transformer neutral point.
