Abstract
The invention, which belongs to the technical field of the power auxiliary tool, discloses an aluminum parallel groove unit comprising an upper clamp plate and a lower clamp plate. At least two grooves are formed in each of the upper clamp plate and the lower clamp plate. After the upper clamp plate and the lower clamp plate are buckled, the grooves correspond to each other; and bolts arranged at rows are arranged between two adjacent grooves at the left outer sides and the right outer sides of the grooves, so that the upper clamp plate, a lead, and the lower clamp plate are locked tightly. According to the invention, with the groove unit, defects of the existing aluminum parallel groove can be overcome. The groove unit has advantages of simple structure, firm connection, and high safety and reliability; the lead compression strength is substantially improved; the potential safety hazard of the line is eliminated; problems that the aluminum parallel groove joint is easy to loosen and the lead joint is easy to heat can be solved; and reliability of the electric transmission and distribution circuit operation can be improved.
Description
Technical field
The present invention relates to electric power aid technical field.
Background technology
In power transmission and transformation line construction, aluminium ditch are the line standard gold utensils often used, and Main Function is coupled together by twolink, or by two aluminum steel parallel connections, increase sectional area of wire, increase ampacity, improve power delivery capabilities.
Aluminium conventional now ditch exists some problems in design, aluminum base is provided with draw-in groove, is stuck in groove by two aluminum conductors, relies on three compressing tablets above aluminum steel to be fixed on base plate by aluminum steel, fix owing to each compressing tablet only having a bolt, tautness is not strong, under electric load or External Force Acting, easily causes loosened screw, dropout, wiring is caused to loosen, conductor overheating, even joint burns, and runs bring potential safety hazard to power circuit.For solving due to aluminium and the design defect problem that exists of ditch, eliminating line security hidden danger, needing to study a kind of novel aluminum and ditch, to eliminate aluminium and ditch joint easily loosens, the problem of conductor overheating.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, there is provided a kind of aluminium and ditch, solve original aluminium and the defect problem of ditch existence, structure is simple, is connected firmly, safe and reliable, substantially increase wire compactness strengthen, eliminate line security hidden danger, eliminate aluminium and the problem that ditch joint easily loosens, terminal generates heat, improve power transmission and transformation line reliability of operation.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of aluminium ditch, it is characterized in that comprising train wheel bridge and lower plate, train wheel bridge and lower plate are provided with at least 2 grooves, after train wheel bridge and lower plate make-up, groove location is corresponding, has row's bolt, train wheel bridge, wire and lower plate are locked between 2 grooves that the left outside limit of groove and right outside limit are often adjacent.
As preferably, described groove is the semicircle of aluminum steel diameter matches or is less than semicircle.
As preferably, described at least 2 grooves are 2 grooves.
As preferably, described bolt is often arranged and is provided with 2 ~ 6.
As preferably, described train wheel bridge and lower plate all adopt antioxidation aluminium alloy material to make.
The beneficial effect adopting technique scheme to produce is: the invention solves original aluminium and the design defect problem of ditch existence, structure is simple, practical, upper and lower two panels aluminium sheet is adopted to construct, two panels aluminium sheet is provided with groove, aluminum steel is firmly fixed in wire casing, with a left side, in, upper and lower two panels aluminium sheet steps up by right three row's bolts, aluminum steel stress equalization in draw-in groove, contact closely with aluminium sheet, even if vibrations large more also can not cause bolt looseness, substantially increase wire compactness strengthen, reduce the labour intensity of engineering construction personnel, eliminate line security hidden danger, eliminate aluminium ditch joint easily to loosen, the problem of terminal heating, improve power transmission and transformation line reliability of operation.Aluminium sheet adopts antioxidation aluminium alloy material to make, and is not easy oxidized, and useful life increases, and reduces the labour intensity of engineering staff.
