Abstract
The utility model provides a bus duct. The bus duct comprises a shell. The shell is formed by a side plate and a cover plate. One end of the cover plate is provided with a U-shaped groove which is reversely extended. Bottom ends of two side edges of the U-shaped groove are provided with crochets. The bus duct of the utility model has the advantages that the bus duct possesses high bending strength and good corrosion resistance performance; heat dissipation performance is good. By using the bus duct as a grounding protection body, a grounding resistance can be reduced so that safe protection performance is good.
Description
Technical field
The utility model relates to a kind of bus duct, belongs to the bus duct technical field.
Background technology
Present existing bus duct shell comprises: side plate, cover plate; Side plate and cover plate all are to adopt the Q235 steel plate to process, so the Corrosion Protection of side plate and cover plate is relatively poor, the bending strength of side plate and cover plate is low, the poor electric conductivity of side plate and cover plate, thereby: present existing bus duct shell Corrosion Protection is relatively poor, the loop resistance of present existing bus duct shell is bigger in addition, and then: the bus duct shell can not use as the bus duct earth electrode.
The utility model content
The purpose of this utility model is to overcome above deficiency; A kind of bus duct shell with bending strength and corrosion resistance is provided.
A kind of bus duct comprises shell, and described shell is made up of side plate, cover plate, wherein, the U-lag that is provided with reverse extension of an end of described cover plate, the bottom of described U-lag dual-side is provided with crochet.
Above-mentioned bus duct, wherein, described side plate, cover plate all are the almag section bars.
Above-mentioned bus duct, wherein, described cover inner surface is zigzag, the side plate outer surface is zigzag.
The beneficial effects of the utility model are:
The bending strength that the utlity model has superelevation reaches corrosion resistance preferably, and thermal diffusivity of the present utility model is good, adopts the utility model as the ground protection body, can reduce earth resistance, and safety guarantee is higher.
Description of drawings
Fig. 1 is the structural representation of side plate of the present utility model.
Fig. 2 is structure of cover plate schematic diagram of the present utility model.
Embodiment
A kind of bus duct, comprise shell, described shell is made up of side plate 11, cover plate 12, the U-lag that is provided with reverse extension 121 of one end of described cover plate 12, the bottom of described U-lag 121 dual-sides is provided with crochet 122, and described side plate 11, cover plate 12 all are the almag section bars, cover plate 12 inner surfaces are zigzag, side plate 11 outer surfaces are zigzag, because cover plate 12 inner surfaces are zigzag, side plate 11 outer surfaces are zigzag; Therefore, the thermal diffusivity of side plate and cover plate is good, thereby, improved integral heat sink of the present utility model.
In sum, the bending strength that the utlity model has superelevation reaches corrosion resistance preferably, and thermal diffusivity of the present utility model is good, adopts the utility model as the ground protection body, can reduce earth resistance, and safety guarantee is higher.
Claims (3)
