Technical field

The present invention relates to low-tension switch cabinet field more particularly to a kind of low-tension switch cabinet top cover fractal structures.

Background technique

At present in low-tension switch cabinet field, component part of the top cover as switchgear always is and is gone out with an entirety It is existing, after top cover is removed when installing at the scene, cabinet top bus bar is connected, because size is big, disassembly is inconvenient；It is especially electric The cabinet gone out on cable, after cable passes through top cover, when bus needs to overhaul, top cover is taken not get off, and busbar overhaul is extremely difficult.Cause This, solving the problems, such as when low-tension switch cabinet top cover is inconvenient and overhauls during installation that busbar overhaul is extremely difficult just seems especially It is important.

Summary of the invention

In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of low-tension switch cabinet top cover fractal structures, lead to It crosses and top cover is divided into front and back two parts, and corresponding preceding bus chamber cap and rear cable chamber cap are set on top cover, after top cover is split Convenient for factory's assembly, and it is as needed in maintenance, preceding bus chamber cap and rear cable chamber cap are dismantled, convenient for bus It is overhauled, solves the problems, such as that busbar overhaul is extremely difficult when low-tension switch cabinet top cover is inconvenient and overhauls during installation.

The present invention provides a kind of low-tension switch cabinet top cover fractal structure, including top cover, and the top cover lower end is provided with cabinet body Frame, the top cover are divided into front and back two parts, and top cover is divided into front and back two parts by top cover intermediate washer, it is characterised in that: Preceding bus chamber cap and rear cable chamber cap are provided on the front of the top cover, the preceding bus chamber cap and rear cable chamber cap distinguish position Above bus-bar room and above cable vault, the preceding bus chamber cap and rear cable chamber cap are mounted on top cover by screw, are being needed Preceding bus chamber cap and rear cable chamber cap are opened by disassembly screw when wanting.

Further improvement lies in that: the preceding bus chamber cap and rear cable chamber cap surrounding are provided with sealing strip, pass through sealing strip The gap generated after preceding bus chamber cap and the installation of rear cable chamber cap is sealed.

Further improvement lies in that: the top cover two sides are provided with water fender, by water fender by water remaining at the top of top cover It is oriented to.

Further improvement lies in that: the depth of the preceding bus chamber cap is 600mm, and the depth of rear cable chamber cap is 400mm.

Further improvement lies in that: top cover upper end four corners are provided with hoisting ring, and leakage is provided on the rear end face of top cover Water hole.

The beneficial effects of the present invention are: by the way that top cover is divided into front and back two parts, and corresponding preceding mother is set on top cover Line chamber cap and rear cable chamber cap, top cover assemble after splitting convenient for factory, and as needed in maintenance, to preceding bus chamber cap and Cable chamber cap is dismantled afterwards, convenient for overhauling to bus, improves overhaul efficiency, and by sealing strip and water fender to low The cabinet that compresses switch is sealed and waterproof, improves the service life and safety of equipment.
