いる。That is, Fig. 2 shows the structure of this type of lightning arrester, and S
Inside the insulator tube 1 filled with an insulating gas such as Fa gas, a lightning arrester internal element 2 for providing a predetermined rated voltage 19 is installed inside the insulator tube 1.
A receiver provided on the head is supported and housed in a plate 3 via a spring 4. The plate 3 of the receiver is provided with a pressure release port 3a,
A pressure membrane 5 is disposed on the outside so as to close the pressure relief port 3a, and the plate 3 and the pressure membrane 5 are fixed to the head of the insulator tube 1 together with a packing 6 by a metal cover 7. ing. That is, the head of the insulator tube 1 is covered with a metal aperture cover 7 for hermetically sealing the lightning arrester, and the periphery of the metal aperture cover 7 wraps around the receiving plate 3 and the pressure-covered film 5. It is caulked and fixed to the jaw 8 of the insulator tube. The metal aperture cover 7 is made of a thin plate made of stainless steel or the like, and has a pressure release port 9 opened in its center. Also,
An arc guide 11 is fixed to the outer surface of the metal aperture cover 7 via a connecting plate 10, and a terminal 12 is attached to the outer surface of the arc guide 11. On the other hand, an arc guide 11 to which a terminal 12 is attached is provided on the leg portion of the insulator tube 1.
A base 13 is installed on this arc guide 11.

があった。However, in the above-mentioned lightning arrester, the metal aperture cover 7 is simply a thin metal plate caulked and fixed to the jaws 8 of the head of the insulator tube 1 as shown in the figure. However, when the pressure is released, high-pressure gas generated inside the arrester blows out from the pressure release port 9, and when that pressure is applied to the arc guide 11, the load on the arc guide 11 is absorbed by the metal aperture cover. 7, and there was a possibility that the metal aperture cover 7 itself would fall off.

気密性が損われる問題点があった。(Problems to be Solved by the Invention) As described above, in the conventional lightning arrester, the arc guide and the metal aperture cover 7 are integrally constructed, and the load when the pressure is released from the surge arrester or the tensile load applied to the terminal 12 of the surge arrester is reduced. Since all the load was placed on the metal aperture cover 7, there was a problem that the airtightness of the metal aperture cover was impaired.
