High-voltage lightning arrester with glue storage moisture-proof sealing structure

In order to solve the technical problems that an internal sealing structure of an arrester is simple and crude, the sealing failure risk is high and the reliability is poor, the invention provides a high-voltage lightning arrester with a glue storage moistureproof sealing structure. The lightning arrester comprises an end cover, a pressing plate, a cover plate, a porcelain jacket and a resistor disc, wherein the pressing plate is fixedly connected with the cover plate; a sealing structure is arranged between the pressing plate and the cover plate; an explosion-proof plate is arranged between the pressing plate and the cover plate; a sealing piece is arranged between the explosion-proof plate and the cover plate, a sealing structure is arranged on the contact surface of the cover plate and the porcelain jacket, and the sealing structure comprises two rubber seals, namely an O-shaped seepage-proof sealing ring outside the cover plate and an O-shaped leakage-proof sealing ring inside the cover plate, and a U-sha
