とを特徴とする３電極形ガス入アレスタ。 A plurality of hollow cylindrical bodies formed of an insulating member are airtightly attached to the openings at both ends of each of the hollow cylindrical bodies by welding a low melting point metal so as to form a sealed chamber, and within each of the hollow cylindrical bodies. In a three-electrode gas-filled arrester in which each discharge surface has two main electrodes and an intermediate electrode facing each other with a gap therebetween, and an inert gas is sealed in the sealed chamber, the three electrodes are arranged in each hollow space. At least two of the three electrodes are formed of a conductive member having a larger thermal expansion coefficient than the cylindrical body, and at least two of the three electrodes each include a sealing electrode portion having a flange portion attached to both end openings of the hollow cylindrical body, and the sealing electrode portion. It is formed by the discharge electrode section attached to the center of the wearable electrode section, and each discharge gap size between the respective discharge surfaces of the three electrodes is such that the three electrodes are connected with the discharge surfaces in contact with each other. The hollow cylindrical body is airtightly attached to each opening at each end by welding a low-melting point metal, and when cooled to room temperature after installation, the difference in thermal expansion coefficient between the three electrodes and each of the hollow cylindrical bodies occurs. A three-electrode gas-filled arrester characterized by having different gap sizes.
