Abstract
The invention relates to a flexibility stress low-voltage bus duct, and belongs to the technical field of low-voltage power transmission and distribution. The flexibility stress low-voltage bus duct comprises a flexible connection portion and two bus duct bodies, wherein a bus bar arranged at one end of each bus duct body is branched, and the flexible connection portion is connected to the end, with the branched bus bars, of each bus duct body, so that the two bus duct bodies are connected into a whole. According to the flexibility stress low-voltage bus duct, due to the facts that the flexible connection portion is added to the flexibility stress low-voltage bus duct, and stress generated by thermal expansion and cold contraction of the flexibility stress low-voltage bus duct is absorbed through the flexible connection portion, the flexibility stress low-voltage bus duct has the advantages that the phenomenon of deformation of the flexibility stress low-voltage bus duct is eliminated, and system operating performance of the flexibility stress low-voltage bus duct is improved. According to the further improvement of the flexibility stress low-voltage bus duct, the flexibility stress low-voltage bus duct comprises upper cover plates, lower cover plates, an upper guide rail and a lower guide rail, wherein rollers are installed on the cover plates respectively, the upper guide rail and the lower guide rail are clamped on the upper cover plates and the lower cover plates respectively, slot holes are formed in the upper guide rail and the lower guide rail respectively, the rollers can slide in the slot holes, and the bus duct bodies are prevented from deviation in the process of extension and contraction. The flexibility stress low-voltage bus duct comprises an outer shell, wherein the outer shell is used for protecting the flexible connection portion and the exposed bus bars.
Description
technical field
The invention belongs to low pressure power transmission and distribution technical field, while relating in particular to a kind of bus duct system energising operation, can absorb the flexibility stress low voltage bus bar groove of bus duct stress.
Background technology
Low voltage bus bar groove is the staple product that electric power transfer is responsible in low pressure power transmission and distribution field, in large electric current and industrial and mineral, factories and miness place, has cable a little incomparable.At present, many large-scale standardization factory buildings and skyscraper adopt low voltage bus bar groove as power transmission and distribution device more and more widely, owing to there being expansion joint in building, during bus duct energising operation, the meeting that affects that busbar is expanded with heat and contract with cold produces stress to whole bus duct system, if not effectively the Stress Release, the elimination that produce, will cause bus duct distortion, affect the operation of system.A lot of places, owing to not considering when bus duct designs, while causing operation, bus duct distortion, causes whole piece bus duct scaling loss, and even a large amount of power consumption equipment scaling loss, cause serious economic loss, and potential safety hazard.
The conventional method that solves bus duct expansion is by the oval waist of joint busbar punching hole, by oval waist hole, regulates bus duct to expand, and this method effect is very little, cannot really eliminate and expand to bus duct influence on system operation.
Summary of the invention
The invention provides a kind of flexibility stress low voltage bus bar groove, while having solved bus duct system energising operation, whole bus duct Stress Release problem.
The technical solution used in the present invention is, a kind of flexibility stress low voltage bus bar groove comprises and being flexible coupling and the bus duct of two joint one end busbar bifurcateds, described in be flexible coupling and be connected to one end of bus duct busbar bifurcated, two joint bus ducts are connected into integral body.
Flexibility stress low voltage bus bar groove of the present invention installs additional and is flexible coupling in bus duct, by being flexible coupling to absorb busbar the produced stress that expands with heat and contract with cold, reaches the beneficial effect of eliminating bus duct distortion, improving bus duct system runnability.
As the present invention, further improve, flexibility stress low voltage bus bar groove comprises and the upper and lower cover plate of roller bearing is housed and is stuck in the upper and lower guide rail on upper and lower cover plate, described upper and lower guide rail is provided with the slotted hole rolling for described roller bearing, prevents bus duct offset direction in telescopic process; Flexibility stress low voltage bus bar groove comprises shell, for protecting, is flexible coupling and exposed busbar.
Accompanying drawing explanation
Accompanying drawing is flexibility stress low voltage bus bar groove stereo decomposing structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is made and being further illustrated.
As shown in the figure, flexibility stress low voltage bus bar groove of the present invention comprises the bus duct 1 of the 2 and two joint one end busbar bifurcateds that are flexible coupling, and is flexible coupling and is connected to one end of bus duct busbar bifurcated, and two joint bus ducts are connected into integral body.Materials such as can adopting copper litz wire or multiple layer of copper expansion joint is flexible coupling, while installing and using, in bus duct system, according to field condition, right quantity flexibility stress low voltage bus bar groove of the present invention is arranged at interval, when bus duct system is subject in building expansion joint and bus duct energising operation, busbar is subject to the stress that expands with heat and contract with cold and produce, and all by being flexible coupling in flexibility stress low voltage bus bar groove of the present invention, is absorbed.
As preferably, flexibility stress low voltage bus bar groove, comprise upper cover plate 6, lower cover, upper rail 4 and lower guideway, upper and lower cover plate is all equipped with roller bearing 3, and roller bearing is 4 on the upper cover plate of two joint bus ducts and lower cover, and is arranged in and is flexible coupling in flexible same rectilinear direction, upper and lower guide rail is stuck on upper and lower cover plate, upper and lower guide rail is provided with the slotted hole rolling for described roller bearing, and the bus duct that roller bearing is housed is packed in guide rail, prevents bus duct offset direction in telescopic process.
As preferably, flexibility stress low voltage bus bar groove, comprises shell 5, is flexible coupling and one end of bus duct busbar bifurcated is all housed in described shell, for protecting, is flexible coupling and exposed busbar.
Flexibility stress low voltage bus bar groove of the present invention can be ignored busbar owing to having expansion joint, bus duct energising operation in building and be subject to the impact of expanding with heat and contract with cold on whole bus duct system operation; Realize the standardized designs of expansion joint in bus duct system, without after system operation, bus duct being adjusted, improved properties of product.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
