When the hanging insulator 5 collides with the lightning arrester 17 by instantaneously rotating in the direction of arrow P in the figure (railway direction), the lightning arrester 17 will move along with the movable support plate 12 in FIG.
Since the lightning arrester 17 receives a rotational force that attempts to rotate in the direction of the arrow Q in the figure around the connecting pin 13, the breaking ability against the shearing load applied to the stopper bolt 15 due to the principle of leverage is reduced before the lightning arrester 17 is damaged. Because it is designed to be lower than
The stopper bolt 15 is sheared, and the lightning arrester 17 rotates together with the movable support plate 12 in the direction of the arrow Q. As a result, the collision energy of the hanging insulator 5 against the lightning arrester 17 is alleviated, and damage to the rubber mold 21 of the lightning arrester, damage to the current limiting element (not shown), or breakage of the lightning arrester 17 is prevented, and damage to the lightning arrester F is prevented. Safety can be improved by eliminating scattering of debris.
