Claims

[Scope of utility model registration request]

A gas-filled discharge tube type three-electrode lightning arrester in which a gas discharge gap is formed between an intermediate electrode and a pair of end electrodes via a plurality of insulating tubes, and the insulating tubes and electrodes have approximately the same outer diameter. , a ground terminal plate extending from the outside of the intermediate electrode;
a pair of line terminal plates that are parallel to the arm terminal plate and extend from the outside of the end electrode; a molten body that is brought into contact with the outside near the ground terminal plate and is thermally coupled to the discharge heat; a contact piece that projects from the line terminal plate to approximately the middle in the thickness direction of the molten body, is normally spaced apart from the short circuit plate, and comes into contact with the short circuit plate as the molten body melts; A short-circuit mechanism for a communication protector comprising an insulating case that houses each of these elements.
