Abstract
The utility model discloses an aluminum cable steel-reinforced bus-bar expansion joint, comprising an aluminum cable steel-reinforced and bus mounting components fixed on two ends of the aluminum cable steel-reinforced. The aluminum cable steel-reinforced comprises a steel core inside and an aluminum conductor on the external. Using the characteristics that the steel core has relatively good strength and elasticity, the bus-bar expansion joint effectively achieves an objective of uniform force, and preventing to form a corniform structure. The aluminum cable steel-reinforced forms an arc structure after installation. When external forces apply on the bus-bar expansion joint, the whole bus-bar expansion joint is uniform and relatively balanced, strength transmission is relatively uniform, and force applying dead space does not exist, thereby effectively preventing situation that a conventional bus-bar expansion joint is easy to break from occurring, and greatly ensuring safe and stable operation of a power grid. The bus-bar expansion joint is simple and practical, and is low in cost, uniform in load carrying, and good in fracture resistant property. The bus-bar expansion joint is worthy of wide popularization and application.
Description
Technical field
The utility model relates to a kind of bus telescoping joint, relates in particular to a kind of steel reinforced aluminium conductor bus telescoping joint.
Background technology
At present, in electric power system, the almag bus telescoping joint model of using is MS-125 × 10, and the long and soft connection length dimension of aluminium sheet size deficiency in bus telescoping joint, causes bus telescoping to save soft when mounted bending radius too small, easily at soft place, form dog leg, when being subject to External Force Acting, cause strength transmission inhomogeneous, uneven, the effect that the place, summit at angle is subject to power is relatively more frequent and concentrate, as easy as rolling off a log fracture, is having a strong impact on the safe and stable operation of transmission line.
Authorizing disclosed application number on June 26th, 2013 is that 201320039407.6 utility model patent discloses a kind of copper aluminium busbar expansion joint, comprise connecting portion and the aluminum fixed part and the copper aluminium fixed part that are arranged on connecting portion two ends, described connecting portion consists of some aluminium flake stacks, and by welding, be integrated between each aluminium flake, described copper aluminium fixed part upper, the last scale copper that is provided with in lower surface, and scale copper and copper aluminium fixed part are integrated, its weak point is: in actual applications, some aluminium flakes of middle interconnecting piece easily form angular structure, the pulling force that outer aluminium flake is subject to is larger, and internal layer aluminium flake is subject to larger squeezing action, the fracture of the as easy as rolling off a log stressed outer aluminium flake and the internal layer aluminium flake that cause connecting portion, and then cause the aluminium flake of connecting portion to rupture layer by layer, and after flexural deformation, within aluminium flake, easily shelter evil people and countenance evil practices, greatly reduced the performance of bus telescoping joint.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of stressed evenly and effectively avoid forming the steel reinforced aluminium conductor bus telescoping joint of angular structure.
For realizing the technical scheme that the purpose of this utility model adopts, be: a kind of steel reinforced aluminium conductor bus telescoping joint, comprise steel reinforced aluminium conductor and the bus fixture that is arranged on described steel reinforced aluminium conductor two ends, described steel reinforced aluminium conductor comprises inner steel core and outside aluminium stranded conductor layer.
Described steel reinforced aluminium conductor arranges insulating protective layer outward.
Described bus fixture is anchor ear.
Described bus fixture comprises firm banking and the sliding part on described firm banking is set, on described sliding part, is provided with anchor ear.
Described firm banking is provided with chute, and described sliding part comprises the slide block of bottom and the nut being threaded with described slide block, and described slide block is arranged in described chute.
Steel reinforced aluminium conductor bus telescoping of the present utility model saves by steel reinforced aluminium conductor and bus fixture are set, utilize steel core to there is good intensity and this feature of elasticity, effectively realized the utility model bus telescoping joint stressed evenly, avoid forming the object of angular structure, steel reinforced aluminium conductor forms arc-shaped structure after installation, the stressed even and comparison balance of whole expansion joint when being subject to External Force Acting, strength transmission is also more even, there is not stressed dead angle, effectively avoided the easily situation generation of fracture of traditional bus telescoping joint, greatly ensured the safe and stable operation of electrical network.Steel reinforced aluminium conductor arranges insulating protective layer outward, has effectively avoided steel reinforced aluminium conductor oxidized, has ensured that steel reinforced aluminium conductor has good performance, has extended the useful life of expansion joint effectively; Bus fixture adopts anchor ear, simple in structure, easy and simple to handle, fixing reliable; Bus fixture adopts on firm banking sliding part is set, effectively realized the function that regulates bus telescoping joint two ends distance, so that in actual applications according to the difference of application scenario, regulate, greatly expanded the range of application of bus telescoping joint, and be very easy to job execution, improved operating efficiency; Anchor ear is set on sliding part, be convenient to fixing steel reinforced aluminium conductor, firm banking is connected with slide block by chute with sliding part, and the nut being threaded is set on sliding part, conveniently moving on the one hand, on the other hand, spacing fixing by nut, convenient effective, and adopt anchor ear to be connected with steel reinforced aluminium conductor, easy, reliable; This reality novel simple and practical, cost is low, stressed even, anti-fracture performance is good, application should be widely promoted.
