Connection protection device of flexible graphite lightning protection grounding belt

Abstract

The invention discloses a connection protection device for a flexible graphite lightning protection grounding belt, and the device is characterized in that the device comprises an installation box, afirst graphite cable and a second graphite cable, the top of the installation box is provided with a cover plate, the cover plate comprises a top plate and a pressing plate, and the bottom end of thetop plate is fixedly provided with the pressing plate; a rectangular clamping block is arranged at the bottom end of the top plate and surrounds the outer surface of the pressing plate, a rectangularclamping groove matched with the rectangular clamping block is formed in the top of the mounting box, and a communicating cavity is formed in the mounting box. The invention has the beneficial effectsthat the rectangular clamping blocks are inserted into the rectangular clamping grooves, so the sealing performance of connection is improved; after completion, the threaded rod can be rotated, the T-shaped part at the bottom of the threaded rod rotates in the T-shaped groove, and finally the moving block is driven to descend, so the graphite cable in the through hole is extruded, and the sealingstrip is arranged, so the graphite cable penetrates through the through holes in the two ends, the through hole can be completely sealed, and the graphite cable is moved, so the connection is more sealed, and the communicating cavity is in a sealed state.

Description

technical field [0001] The invention relates to the field of lightning protection and grounding, in particular to a connection protection device for a flexible graphite lightning protection and grounding belt. Background technique [0002] In the field of electric lightning protection and grounding, steel, copper metal materials, galvanized steel, copper-clad steel and other plated alloy materials are usually used as the grounding material of the power grounding grid. Due to the fact that metal materials are inevitably subject to corrosion problems during the operation of more than ten years or even decades. Graphite cable grounding material is a new type of grounding material that has emerged in recent years. It effectively solves the corrosion problem of metal grounding materials and is widely used in the field of electric lightning protection grounding. Different from conventional welding connection methods such as electric welding, gas welding and exothermic welding of ...
