Description

Intensive bus duct joint sealing structure

Technical Field

The utility model relates to a dense bus duct connects solid structure of sealing.

Background

The bus duct has stronger superiority in the fields of industry, high-rise buildings and the like which need large-current power transmission compared with the traditional cable power transmission mode.

The bus duct is a closed metal device mainly composed of copper and aluminum bus posts, can be used for distributing large power for various elements of a decentralized system, and has increasingly replaced wire cables in indoor low-voltage power transmission main line engineering projects. When connecting two bus ducts, in the common intensive bus duct joint design scheme, it exists to be the cavity between the inside spare part after the connector installation is accomplished, is being filled with a large amount of air in the cavity, because the coefficient of heat conductivity of air is very low, this kind of structure can influence the giving off of bus duct conductor heat, leads to inside temperature rise to be difficult to reduce, influences the electrical property, the energy-concerving and environment-protective characteristic of direct influence bus duct, the temperature rise is too high even can lead to intensive bus duct's life decay too fast.

Disclosure of Invention

The utility model aims at solving the defects of the prior art, and providing a dense bus duct joint sealing structure.

The utility model provides an intensive bus duct connects solid structure of sealing, includes barrel and apron, the barrel include bottom plate and connecting piece, the connecting piece pass all copper bars in proper order, the top of connecting piece is equipped with the apron, the apron pass through the spring and link to each other with the bottom plate, the spring be located the inner chamber of connecting piece, when the spring is in tensile state, the bottom butt of apron is on the upper surface of the copper bar of the top.

Preferably, at least two springs are provided in a single connector.

Preferably, the cross section of the connecting piece is rectangular.

Preferably, the outer walls of the cover plate and the cylinder body are respectively provided with an insulating coating.

Preferably, the lower surface of the cover plate is provided with a rectangular groove matched with the cylinder body.

Preferably, the spring is made of stainless steel.

Has the advantages that:

this device sets up solid structure through the both ends at the inside copper bar of bus duct, can effectually prevent to produce the clearance between the copper bar to influence the effective heat dissipation of copper bar.

When the copper bar fixing device is used, all the upper and lower copper bars are fixed together by the cover plate and the barrel under the elastic action of the spring, and gaps can be effectively prevented from being generated between the copper bars.

Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 1-2, the dense bus duct comprises a top plate 1, side plates 3 and five copper bars 2 located inside.

As shown in fig. 3-4, a dense bus duct joint sealing structure comprises a cylinder 42 and a cover plate 41, wherein the cylinder 42 comprises a bottom plate and a connecting piece, the connecting piece sequentially penetrates all copper bars, the cover plate is arranged at the top of the connecting piece and is connected with the bottom plate through a spring 43, the spring 43 is positioned in an inner cavity of the connecting piece, and when the spring is in a stretching state, the bottom of the cover plate 41 abuts against the upper surface of the uppermost copper bar 2.

Two springs 43 are arranged in the single connecting piece, and the springs 43 are made of stainless steel.

The cross section of the connecting piece is rectangular, the lower surface of the cover plate 41 is provided with a rectangular groove matched with the cylinder body, and the outer walls of the cover plate and the cylinder body are provided with insulating coatings.

After the connection, under the action of the spring 43, the cover plate 41 and the cylinder 42 tightly adhere the five copper bars 2 together, so that gaps are prevented from being generated between the copper bars 2, and the heat dissipation of the whole intensive bus duct is influenced.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
