ABSTRACT:
A gas-tube arrester includes an arrester body in which an inert gas is contained, and first and second electrodes face each other separated by an insulator. An insulating, heat-resistant film is in contact with the first electrode and has a plurality of small holes. A low-melting point metal plate layered on the insulating film has a melting point lower than a decomposition or softening temperature of the insulating film. A conductive leaf spring electrically connected to the second electrode presses the low-melting point metal plate toward the insulating film, so that, when a high voltage is applied between the first and second electrodes, an electrical discharge occurs between the first and second electrodes through the small holes of the insulating films. The leaf spring has an extend portion bent toward the first electrode, so that, if the low-melting point metal plate is melted by heat from the arrester body, the melted metal will electrically connect the extended portion of the leaf spring to the first electrode.
