Clasp type intensive bus groove shell

Abstract

The invention belongs to power transmission equipment, and relates to a shell structure of an intensive bus groove, in particular to a clasp type intensive bus groove shell. The clasp type intensive bus groove shell comprises an upper cover plate, a lower cover plate and a fixed lateral plate which is connected between the two cover plates and deviates to one side, the two cover plates and the fixed lateral plate are made of aluminum alloy profile with an integral structure, the position deviating to the other side between the two cover plates is provided with a movable lateral plate with C-shaped section, and hems of the upper end and the lower end of the movable lateral plate are connected and fixed with the cover plates through bolts or rivets; and the two hem edges of the movable lateral plate are folded outwards to form two sealed grooves positioned at the outside, the bottoms of the sealed grooves are provided with gland strips, the edges of the upper cover plate and the lower cover plate are inserted into the sealed grooves and pressed on the gland strips, and the edges of the upper cover plate and the lower cover plate and the side walls of the sealed grooves are provided with clasps which are mutually matched. The clasp type intensive bus groove shell has the advantages of simple structure, convenience for mounting and good waterproof effect.

Description

technical field [0001] The invention belongs to power transmission equipment, and relates to a shell structure of a medium-intensive bus duct, in particular to a hook-type intensive bus duct shell. Background technique [0002] In the existing power transmission busbar system, the shell structure of dense busway is usually as attached figure 1 And attached figure 2 As shown, it consists of upper and lower cover plates 11 and two C-shaped side plates 12 on both sides. The flanges on the side plates and the lower ends are respectively connected and fixed with the two cover plates by bolts or rivets. This structure not only has many connection points on the shell, but also requires a lot of assembly work, and the connection part of the shell is easy to seep water during use, which affects the safe operation of the equipment. Therefore, it is usually necessary to seal the joint between the side plate and the top plate. Glue, which further increases the workload of installatio...

Problems solved by technology

This structure not only has many connection points on the shell, but also requires a lot of assembly work, and the connection part of the shell is easy to seep water during use, which affects the safe operation of the equipment. Therefore, it is usually necessary to seal the joint between the side plate and the top plate. glue, which further increases the workload of installation, and during the operation of the equipment, the sealant is also easy to age and fall off, and the waterproof effect cannot be guaranteed
