る避雷器の開放機構。An electrode having a through hole in the shape of a zinc oxide varistor is brought into contact with the zinc oxide varistor element in an electrically and thermally conductive manner, and the tip of a metal rod with a force applied in the direction of pulling it apart by a spring is inserted into the conductive hole. A lightning arrester comprising a mechanism in which the tip of a rod and an electrode are joined with a low melting point alloy filled in a through hole, and the electrode and the metal rod are separated by melting the low melting point alloy as the temperature of the varistor element increases. In this case, a counterbore with a diameter larger than the maximum diameter of the through-hole and concentric with the through-hole is provided on the outside of the widened end of the giant electrode near the varistor element of the through-hole. A lightning arrester opening mechanism characterized by the following features:
