Quick coupler for in-out cables of high- voltage switch cabinet

Abstract

The invention relates to the electrical equipment field, especially a quick coupler for in-out cables of a high- voltage switch cabinet which is characterized by comprising a hollow inner conductor; the hollow inner conductor comprises a columnar part and a tapered part; the tapered part and the columnar part are equipped with oppositely arranged first ends and second ends; the end of the tapered part connected with the columnar part is constructed into the first end; the other end is constructed into the second end; an externally convex clamping structure is arranged at the periphery of the tapered part close to its first end; an elastic slot is arranged at the port of the second end of the tapered part; the end of the columnar part connected with the tapered part is constructed into the first end; the other end is constructed into the second end; a number of shrinkage slots are evenly arranged on the inner conductor along the periphery; the invention also comprises an elastic element sleeving the periphery of the columnar part, and hollow insulation sleeves coating the peripheries of the inner conductor and the elastic element; the insulation sleeves are made of an insulation soft material. The invention can quickly connect the cables, saves connecting time and is good in insulation performance and sealing performance.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a quick connector for cables entering and leaving a high-voltage switch cabinet. Background technique [0002] At present, the quick connectors for the incoming and outgoing lines of high-voltage switchgear and cable wiring are widely used in the field of power switches and wiring. The wiring of power lines has an important impact on the power grid, and the power loss of the cable joint itself is quite alarming. Therefore, improving the power grid line And the wiring speed of the incoming and outgoing lines of the switchgear is also the basic requirement of the power grid. Current power grid lines and switchgear inlet and outlet lines generally use heat-shrinkable joints or cold-shrinkable joints, but the wiring processes of heat-shrinkable joints and cold-shrinkable joints are very complicated, time-consuming and labor-intensive.
