Description

Integrated hollow bus duct

Technical Field

The utility model particularly relates to a cavity type bus duct in integral type.

Background

The bus duct, a closed metal device composed of copper and aluminum bus bars, is used to distribute large power to the elements of the decentralized system, and has been increasingly used as a substitute for wire and cable in the project of indoor low-voltage power transmission main line engineering.

The bus duct is produced as a novel distribution lead, and is a bus system consisting of a metal plate (steel plate or aluminum plate) as a protective shell, a conductive bar, an insulating material and related accessories, and can be made into plug-in type closed buses with plug-in junction boxes arranged at intervals, or feed type closed buses without junction boxes in the middle, however, most of the existing bus ducts are complex in structure, the shell is supported and fixed, and the densely arranged buses fill the interior of the shell to increase the weight of the shell; therefore, a new solution is needed to solve this problem.

Disclosure of Invention

In view of this, the present invention provides an integrated hollow bus duct with a simplified and reasonable structure, a light weight and a good heat dissipation.

In order to solve the technical problems, the technical scheme of the invention is as follows:

the utility model provides a cavity type bus duct in integral type, includes the shell, imbeds female the arranging of a plurality of inside pieces of shell, and the suit is female arranging both ends and with the shell passes through the spiral-lock spare of fix with screw, the shell includes inside hollow insulating housing, sets up on the insulating housing and the bleeder vent that the equidistance arranged and distributes, and set up and establish the dress hole is inlayed at insulating housing both ends, female row passes and utilizes spiral-lock spare to fix after inlaying the dress hole.

Preferably, the upper end and the lower end of the embedding hole are both provided with threaded through holes.

Preferably, the busbar comprises a copper sheet and a plurality of protective sleeves sleeved on the copper sheet, and the size of each protective sleeve is consistent with that of the embedding hole.

Preferably, the number of the sheaths is three, and the sheaths are equidistantly distributed in the middle and two ends of the copper sheet.

Preferably, the sheath is a phenolic resin sheath, and the upper and lower ends of the sheath at the two ends of the copper sheet are both provided with grooves.

Preferably, the buckling piece is arranged in a C shape and comprises a buckling piece body, a rectangular hole formed in the side face of the buckling piece body and through holes formed in the upper end and the lower end of the buckling piece body.

The utility model discloses technical effect mainly embodies in following aspect: the utility model aims at simplifying current bus duct structure, inlaying through female arranging and adorning hollow shell, recycling the spiral-lock spare and fixing, not only reduce its weight, improve its structure and decide nature, still make the bus duct in time to scatter at the heat of during operation, reduce the life of conflagration risk and extension bus duct.

Detailed Description

The following detailed description of the present invention is provided to facilitate the understanding and appreciation of the technical aspects of the present invention in connection with the accompanying drawings.

Examples

The utility model provides a profile bus groove in integral type, as shown in figure 1, includes shell 1, imbeds female 2 of arranging of a plurality of pieces inside the shell 1 to and the suit is in arrange 2 both ends of arranging and with shell 1 passes through the spiral shell binding spare 3 of screw fixation.

As shown in fig. 2 to 3, the housing 1 includes an insulating casing 11 with a hollow interior, air holes 12 disposed on the insulating casing 11 and distributed at equal intervals, and embedded holes 13 disposed at two ends of the insulating casing 11, and the busbar 2 passes through the embedded holes 13 and is fixed by the fasteners 3. Threaded through holes 131 are formed in the upper end and the lower end of the embedded hole 13, and particularly, the fastening piece 3 is convenient to be matched with the embedded hole 13 and then is fixed in a condensation mode through screws.

As shown in fig. 4, the busbar 2 includes a copper sheet 21, and a plurality of sheaths 22 sleeved on the copper sheet 21, wherein the size of the sheath 22 is the same as that of the embedding hole 13, and specifically, the sheaths 22 can be conveniently embedded into the insulating housing 11 for fixing. The sheath 22 is provided with threely, and the equidistance distributes in the middle part and the both ends of copper sheet 21, specifically, can be in the inside stable copper sheet 21 that supports of casing 11 through sheath 22. The sheath 22 is a phenolic resin sheath, and the upper end and the lower end of the sheath 22 at the two ends of the copper sheet 21 are both provided with grooves 221, specifically, screws can be clamped in a matched mode, and therefore the busbar 2 is installed more firmly.

As shown in fig. 5, the fastening member 3 is arranged in a C-shape, and includes a fastening member body 31, a rectangular hole 31 formed in a side surface of the fastening member body 31, and through holes 33 formed in upper and lower ends of the fastening member body 31, specifically, the size of the rectangular hole 31 is the same as that of the copper sheet 21, so that the copper sheet 21 can conveniently pass through the rectangular hole 31.

The utility model discloses technical effect mainly embodies in following aspect: the utility model aims at simplifying current bus duct structure, inlaying the dress to hollow shell through arranging female, recycling spiral-lock spare is fixed, not only reduces its weight, improves its structure and qualifies, still makes the bus duct in time to scatter at the heat of during operation, reduces conflagration risk and the life of extension bus duct.
