Sealing equipment for lightning protection pressure limiter valve plate

Abstract

The utility model discloses a sealing device for a lightning protection pressure limiter valve plate, the sealing device comprises a hollow rubber ring (1), the hollow rubber ring (1) is sleeved on a core body (9) of a lightning protection pressure limiter, the core body (9) is provided with a plurality of valve plates (14), one part of the valve plates (14) are connected with a clamping hook sealing assembly (2) on the hollow rubber ring (1), and the other part of the valve plates (14) are connected with the clamping hook sealing assembly (2) on the hollow rubber ring (1). The clamping hook sealing assembly (2) is arranged on the inner side of the hollow rubber ring (1) and connected with the core body (9). According to the utility model, the hollow rubber ring can be ensured not to displace so as not to influence the sealing performance of the lightning protection voltage limiter, and the rubber material is adopted, so that the lightning protection voltage limiter is closer to surrounding gaps in a narrow space, better waterproof performance can be realized, and the moisture-proof capability of the lightning protection voltage limiter is improved.
