Mounting structure of tank-type lightning arrester for neutral point of transformer

摘要

The present invention is a mounting structure of a neutral point tank-type lightning arrester of a transformer that can reduce the installation area for a transformer neutral point arrester and is small in size and economical. The transformer neutral point arrester mounting structure includes a transformer winding having a neutral point embedded in the transformer tank, and a tank-type arrester having an overvoltage preventing element embedded in the arrester tank. A first opening is formed in an upper portion of the side of the transformer tank and a second opening is formed in the lightning arrestor tank, the first and second openings being connected to each other through an insulating spacer having a center conductor, And is connected to the overvoltage preventing element via the conductor.
