Problems solved by technology

In the existing high-voltage junction box structure, in order to improve the safety performance of its electricity use, it generally has good performances such as shock resistance, sound insulation, and insulation. However, the general high-voltage junction box structure has poor sealing performance and cannot completely protect against external water vapor. Insulation, a high-voltage connection box structure is needed to make it in a good sealing state at the box door after closing

Abstract

A safe and efficient sealing structure applied to a high-voltage box comprises a box body, corner supporting pieces, corner sealing pieces, locking blocks, first springs, second springs, side supporting pieces, side sealing pieces and a box door. A folded edge is arranged in the circumferential direction of the top surface of the box body; and the corner supporting pieces are arranged on the innerside walls of the folded edges, and the outer sides of the corner supporting pieces and the inner side walls of the folded edges form corner hollowedgrooves. Angle limiting blocks are arranged on theouter sides of the two ends of the angle supporting piece; the corner sealing piece is arranged on the outer wall of the corner supporting piece; the locking block is embedded into one end of the angle hollowedgroove and is matched with the angle embedded block, so that the angle sealing piece and the box body are limited and fixed; and the first springs are arranged at the two ends of the cornerhollowedgroove. The second spring is arranged at the middle end of the angle hollow groove; the side supporting pieces are arranged on the inner wall surface of the box body on each side; the side sealing piece is arranged on the top side of the side supporting piece; and the box door and the box body are rotatably arranged through a movable hinge. The sealing structure has stable waterproof andvapor-proof effects, so that the high-voltage power connection box structure is suitable for humid and severe environments such as wharf platforms.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a safe and efficient sealing structure applied to high-voltage boxes. Background technique [0002] The 10KV high-voltage system of the door supply machine on the wharf platform, because the junction box is concealed, sinks below the wharf platform, affected by water vapor, dust, and the annual flood of the Yangtze River, etc., arcing and explosions in the box often occur, seriously endangering the safety of the wharf Production function, and cause power supply line failure. Due to the special location of the high-voltage junction box, it is required that the high-voltage junction box has strong sealing performance to prevent water vapor in the environment from entering the box. In the existing high-voltage junction box structure, in order to improve the safety performance of its electricity use, it generally has good performances such as shock resistance, sound insulation, and...
