Abstract
The utility model relates to a flexible stress low voltage bus duct, and belongs to the low voltage power transmission and distribution technical field; the flexible stress low voltage bus duct comprises a flexible connector and two nodes of bus ducts with one end provided with a branched busbar; the flexible connector is connected with the end, with the branched busbar, of the bus duct, so that the two nodes of the bus ducts are connected in one body; the flexible stress low voltage bus duct adds the flexible connector in the bus duct, so the flexible connector can absorb the stress generated by hot expansion and cold contraction of the busbar, thereby eliminating bus duct deformation and improving operation performance of the bus duct system. As further improvement, the flexible stress low voltage bus duct comprises upper and lower cover plates provided with roller shafts and upper and lower guide rails respectively clamped on the upper and lower cover plates; the upper and lower guide rails are provided with a long hole allowing the roller shaft to roll, thereby preventing direction offset of the bus duct in a telescoping process; the flexible stress low voltage bus duct comprises a housing used for protecting the flexible connector and naked busbars.
Description
technical field
The utility model 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.
Utility model content
The utility model provides a kind of flexibility stress low voltage bus bar groove, while having solved bus duct system energising operation, and whole bus duct Stress Release problem.
The technical solution adopted in the utility model 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.
The utility model flexibility stress low voltage bus bar groove 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 utility model, 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 the utility model flexibility stress low voltage bus bar groove stereo decomposing structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.
As shown in the figure, the utility model flexibility stress low voltage bus bar groove 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 the utility model flexibility stress low voltage bus bar groove 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 the utility model flexibility stress low voltage bus bar groove, 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.
The utility model flexibility stress low voltage bus bar groove 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 concept of the premise utility; can also make some distortion and improvement, these all belong to protection range of the present utility model.
