電電極の形状を工夫することによって、前記気中放電間
隙をほぼ一定に保持することができる。When the device itself swings in the one direction, the lightning arrester and the hanging insulator swing while always maintaining a parallel state, and the air discharge gap between the discharge electrode on the energized side of the hanging insulator and the discharge electrode at the bottom of the lightning arrester is created. is held almost constant. Even when the hanging insulator swings alone in a direction perpendicular to the one direction, the air discharge gap can be kept almost constant by devising the shape of the discharge electrode at the bottom of the lightning arrester.

に捻じれを起こすような無理な力が生じない。Now, the load balance of the electric wire 5 changes due to snow accumulation, etc., and the electric wire 5 swings in the direction of the track. Then, the suspension clamp 24
As shown in FIG. 3, the swing of the electric wire 5 acts on the hanging insulator 6 through the wire, and as shown in FIG. ). In this state, the hanging insulator 6 is rotated around the shaft 18 of the right angle clevis link 17, and the arc horn 25 at the bottom of the hanging insulator 6 moves in an arc around the shaft 18, and the lightning arrester 7 Since it moves approximately corresponding to the curved creeping surface of the discharge electrode 26 at the lower end, the aerial discharge gap G is maintained approximately constant. In addition, the mounting bracket 3 and the lightning arrester 7

Also, at this time, the load on the lightning arrester 7 is applied to the mounting bracket 3 and the hanging insulator 6 by twisting due to the restricted rotation of the mounting bracket 3 in one direction, that is, the rotation within one plane in the vertical direction. The mounting bracket 3 and the hanging insulator 6
deformation is prevented and durability is improved. As a result, the aerial discharge gap G between the arc horn 25 below the hanging insulator 6 and the discharge electrode 26 below the lightning arrester 7 does not change.

The follow-on arc that flows to the support arm 1 of the tower body through the non-linear resistance element and is subsequently generated is blocked by the air discharge gap G and the non-linear resistance element.

The lengths of the two sides of the triangular link mechanism can be adjusted by the arm pieces 13, 15 of 0 and the connecting link 12. Therefore, in order to install this device on the support arm 1 of each tower body, first, the length of the horizontal support arm 10 is adjusted so that a predetermined clearance C1 between the hanging insulator 6 and the lightning arrester 7 is achieved. Set the air discharge gap G. Next, by adjusting the length of the connecting link 12 to horizontally correct the horizontal support arm 10, which tilts from side to side due to the load of the electric wire 5 that changes depending on each tower body, the hanging insulator 6 and lightning arrester in a stationary state can be adjusted horizontally.
