Description

Novel bus duct

Technical field

The utility model belongs to bus duct technical field, more particularly, to a kind of Novel bus duct.

Background technology

Modern high-rise building and large-scale workshop need huge electric energy, and face hundreds and thousands of peaces needed for this huge load It is to select well that the powerful electric current of training, which will select safe and reliable transmission equipment, bus-bar system,.Bus duct system is one The power distribution equipment of a efficient conveying electric current, has especially adapted to higher and higher building and large-scale plant economical rationality wiring It needs；Cable is not easy to boundling management, the reasons such as branch are replaced, bus duct is widely used in fire-fighting by busbar because capacity is small Electric power transmission link.

Bus duct in the prior art will produce a large amount of heat, and existing technology generally can not only be processed using cooling fin Difficulty, and increase cost, it is therefore necessary to it is improved.

Invention content

The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of Novel bus duct, it has The characteristics of having good heat dissipation effect, and being convenient for replacing.

To achieve the goals above, technical solution used by the utility model is：A kind of Novel bus duct, including box body And outer cover plate, the box body include outer housing and inner housing, the outer housing and inner housing are slidably connected, the outer housing and interior It is formed with cavity between shell, offers first through hole on the outer housing, the inner housing is equipped with the second through-hole, and described the One through-hole and the second through-hole Heterogeneous Permutation.

Further, the first through hole is equipped with strainer.

Further, the inner end of the outer housing is equipped with sliding slot, and the outer end of the inner housing is equipped with cooperation sliding slot and slides Dynamic sliding block.

Further, the outer housing is equipped with buckle, for being clamped outer cover plate.

Further, the inner housing is constituted for fire proofing material.

With the above structure, the utility model is compared to the prior art advantageously：The box body packet of the application Outer housing and inner housing are included, wherein outer housing and inner housing is slidably connected and finds the problematic need of circuit when circuit carries out maintenance in this way As long as replacing inner housing when changing, when accidentally outer housing being caused to deform when seated, as long as replacing outer housing, section About material；It wherein is formed with cavity between outer housing and inner housing, first through hole is offered on outer housing, wherein on inner housing Dust-proof, waterproof is played in the case of capable of not influencing cooling effect equipped with this structure of the second through-hole with first through hole Heterogeneous Permutation Effect.

Fig. 2 is the side structure schematic view of the utility model.

Specific implementation mode

As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model It encloses, the utility model is further illustrated with reference to the accompanying drawings and examples.

Embodiment is shown in shown in Fig. 1 to Fig. 2：A kind of Novel bus duct, including box body and outer cover plate 10, it is characterised in that：Its Middle box body includes being formed with cavity 40 between outer housing 20 and inner housing 30, wherein outer housing 20 and inner housing 30, in outer housing First through hole 21 is offered on 20, the second through-hole 31 is equipped on inner housing 30, and wherein first through hole 21 and the second through-hole 31 is wrong Position arrangement corresponds arrangement, preferably uses 31 Heterogeneous Permutation of first through hole 21 and the second through-hole, in this way and first through hole 21 compared with the arrangement mode that the second through-hole 31 is in same level or vertical plane its heat dissipation effect it is identical, but avoid water Or dust is directly entered by first through hole 21 and the second through-hole 31 in box body, and waterproof and dustproof is played the role of.Wherein first is logical Hole 21 is equipped with strainer, further functions as dustproof effect.Wherein outer housing 20 and inner housing 30 is slidably connected, wherein outer housing 20 Inner end be equipped with sliding slot 22, wherein the outer end of inner housing 30 be equipped with cooperation sliding slot 22 slide sliding block 32, work as circuit in this way Inner housing 30 is replaced when needing to change as long as carrying out maintenance and finding that circuit is problematic, accidentally leads to outer housing 20 when seated When deformation, as long as replacing outer housing 20, material is saved.Wherein outer housing 20 is equipped with buckle 23, for being clamped outer cover plate 10.Wherein inner housing 20 is constituted for fire proofing material, is improved refractory ability, is preferably adapted to fire or hot environment, wherein inner casing It is not provided with inner cover plate on body 20, hot inside air can be allowed preferably to carry out flowing in this way and improve radiating efficiency.
