Abstract

The utility model provides a bus slot which comprises a conductive bus bar. A left side plate and a right side plate are respectively arranged on the left and right sides of the conductive bus bar and exert a pre-tightening elastic pressure on the conductive bus bar. The upper and lower ends of the left side plate and the right side plate are respectively connected with an upper cover plate and a lower cover plate. The bus slot provided by the utility model overcomes the defects of the prior art, and a bus slot shell has an elastic pre-tightening effect on a conductor, thereby avoiding the generation of a gap between the bus slot shell and the conductor, ensuring the heat radiation capability of a bus and ultimately reducing the temperature rise during operation of the bus bar.

Description

A kind of bus duct

Technical field

The utility model relates to a kind of bus duct, belongs to electric power conveying technology field.

Background technology

When bus duct adopts intensive insulation mode, because of conductor and housing near together with, the heat that conductor produces can, by the mode of conduction, be delivered to housing, thereby distribute fast.If because bus duct assembling is not tight or bus duct expanded by heating causes the trickle distortion of housing, between conductor and housing, there is gap, the conduction of thermaltransmission mode between solid become by the air gap carries out convection current and radiation, radiating efficiency sharply declines, bus duct internal heat is distributed and is not gone out, and causes temperature rise to raise, and jeopardizes bus duct security of operation, so the tightness degree of conductor and housing directly has influence on the heat radiation of bus duct, and then have influence on the bus duct temperature rise in when operation.

Between existing bus duct conductor and housing, gap is larger, and radiating effect is not good.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of bus duct of perfect heat-dissipating.

In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of bus duct, comprise conductive bus bar, it is characterized in that: left plate, right plate are located at respectively the arranged on left and right sides of described conductive bus bar and conductive bus bar is had to pretension elastic pressure, and the upper/lower terminal of left plate, right plate is connected with upper cover plate, lower cover respectively.

Preferably, described left plate, right plate are the arc that has to the inside radian; Arc comprises vertically disposed arcwall face, and the upper/lower terminal of arcwall face is respectively equipped with horizontal plane; Arcwall face connects described conductive bus bar, and the horizontal plane of arcwall face upper/lower terminal connects respectively described upper cover plate, lower cover.

Preferably, described horizontal plane and arcwall face junction form bent angle to bent intermediate.

A kind of bus duct that the utility model provides is due to the elasticity of left and right side plate material, left and right side plate compresses conductive bus bar to the elastic pressure of conductive bus bar, when left and right side plate upper/lower terminal is bolted on upper and lower cover plate simultaneously, bent angle part also deforms, produce elastic pressure, left and right side plate arcwall face and conductive bus bar extruding are close to.

The device that the utility model provides has overcome the deficiencies in the prior art, and bus groove case, to the flexible pretension effect of conductor, can be avoided producing gap between bus groove case and conductor, guarantees bus duct heat-sinking capability, the temperature rise while finally reducing bus duct operation.

Embodiment

For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.

A kind of bus duct explosive view that Fig. 1 provides for the utility model, described bus duct is comprised of upper cover plate 1, lower cover 2, left plate 3, right plate 4, conductive bus bar 5 five parts.

Left plate 3, right plate 4 are the arc that has to the inside certain radian R.Left plate 3, right plate 4 have three faces, and arcwall face 31 is vertically placed, and arcwall face 31 is upper and lower respectively a horizontal plane 32, and upper and lower horizontal plane forms reverse bent angle 33 to bent intermediate certain distance and is connected with arcwall face 31.

The concrete manufacturing process of bus duct is as follows:

First, with left plate 3, right plate 4, conductive bus bar 5 is clipped in the middle, and starts to compress, as shown in Figure 2.When left and right side plate and conductive bus bar compression, left and right arcwall face 31 produces strains, thereby conductive bus bar 5 is produced to certain elastic pressure N.

Along with pressure increases, left and right side plate arcwall face 31 is progressively driven plain, and final and conductive bus bar 5 is close to.Due to the elasticity of left and right side plate material, left and right side plate compresses conductive bus bar to the elastic pressure of conductive bus bar, then with bolt, the upper/lower terminal of left and right side plate is separately fixed on upper cover plate 1, lower cover 2, as shown in Figure 3.

In conjunction with Fig. 4, when left and right side plate upper/lower terminal is bolted on upper and lower cover plate, bent angle 33 parts also deform, and produce elastic pressure F, and left and right side plate arcwall face 31 and conductive bus bar 5 extruding are close to.

A kind of bus duct that the utility model provides can be avoided producing gap between bus groove case and conductor, guarantees bus duct heat-sinking capability, the temperature rise while finally reducing bus duct operation.
