2 GAS-FILLED SURGE ARRESTER WITH TWO CUP-LIKE ELECTRODES

摘要

The present invention has the two cup-shaped electrode on the air-filled surge arrestor gas. Has an electrode formed of a cup shape by a deep drawing process of a metal sheet with a gas-filled surge arrestor air there, it is simply an electrode terminal is provided whereby the electrode terminal is formed integrally with a ring-like edge region of each electrode. The terminals are separated in the radial direction may contain a part of the external short-circuit device, for example.
