Abstract
The utility model discloses an improvement to bus duct joint design: the existing copper plate connecting plate is formed by overlapping a plurality of soft copper rows, the elasticity of the plurality of soft copper rows is increased compared with that of a single copper plate, and the resistance is reduced. Meanwhile, guide edges are additionally arranged on the upper edge and the edges of the two ends of the connecting plate, triangular and flat plate-shaped wrapping edges are respectively additionally arranged on the edges of the periphery of the joint partition plate, so that a guide opening with wide outside and narrow inside is formed, and the conductive copper bar is easily and accurately inserted. The covered edge increases the creepage distance between the connecting plates, increases the protection of the joint and simultaneously plays a role in strengthening the integral structure of the joint.
Description
The utility model belongs to electricity, and the generating of electric power, power transformation or distribution field relate to the poor joint of a kind of bus.
In the distribution engineering that factory building, heavy construction, boats and ships and the drilling platforms etc. of industrial and mining enterprises are located, using bus duct in a large number.Joint is equipped with at two ends at bus duct, and its structure is: (by three-phase four-wire system and three-phase five-wire mode) every line is provided with a pair of connecting plate, generally adopts copper coin, and the joint dividing plate with insulation between the every pair of connecting plate separates.Connecting plate and joint dividing plate are stacked together, and the two sides clamps with card pressing plate and screw-nut.The conducting copper end of each bar line of bus duct is inserted each respectively between the connecting plate during use, realizes being electrically connected.Existing this class bus duct joint, convenient inadequately during grafting, conducting copper is difficult for aiming at the space of connecting plate, also can insert during insertion or insert partially, the elasticity of connecting plate and resistivity are also not ideal enough, and when the joint dividing plate was moist, the edge of each dividing plate also creepage phenomenon might occur simultaneously.
These deficiencies at prior art the utility model proposes following goal of the invention: improve the structure of bus duct, to increase the elastic strength of connecting plate, reduce its resistance, make grafting convenient simultaneously, peg graft accurately easily.The design also should increase the protectiveness of this joint, strengthens the creepage distance between the connecting plate, and strengthens the bulk strength of joint.
Goal of the invention of the present utility model realizes with following proposal: on the basis of traditional bus duct joint structure, use the copper coin of connecting plate instead multilayer soft copper row stack and constitute for example four layers to eight layers.Simultaneously add guide edge in the top of connecting plate and the edge at two ends, promptly two connecting plates add a flanging to both sides respectively, form targeting port wide outside and narrow inside.Edge at the joint dividing plate adds bound edge, and to strengthen creepage distance and to increase its intensity, the suitable shape of bound edge also can play guide effect.
The utility model has improved the structure of bus duct, and row substitutes copper coin with the multilayer soft copper, has increased the elastic strength of connecting plate, has reduced its resistance again.Add guide edge and make grafting convenient, can be plugged into accurate position at an easy rate.Dividing plate increases bound edge, has strengthened the creepage distance between the connecting plate., increased the protectiveness of joint, and strengthened bulk strength.
Now be described further with accompanying drawing in conjunction with the embodiments.
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the end view of Fig. 1.
Embodiment 1, and with reference to Fig. 1, Fig. 2: the design is identical with existing bus duct joint: every line is provided with a pair of connecting plate (1), and present embodiment is a three-phase five-wire mode, has five pairs of connecting plates.Separate with the joint dividing plate (2) that insulate between every pair of connecting plate.Connecting plate and joint dividing plate are stacked together, and the two sides clamps with card pressing plate (5) and screw-nut (6).Connecting plate adopts six layers of soft copper row stack to constitute, and adds guide edge (7) in the top of connecting plate and the edge at two ends simultaneously, and promptly two connecting plates add a flanging to both sides respectively, form targeting port wide outside and narrow inside, and conducting copper (3) is accurately inserted easily.The elasticity of multilayer soft copper parallelism monolithic copper coin increases, and resistance reduces.Edge at the joint dividing plate adds bound edge, on top with the triangle that is shaped as of two ends bound edge (4), can play the guiding role.Following bound edge (8) be plate shaped, and the bound edge that faces two dividing plates mutually joins, the composition one flat plate, be covered with whole joint below.Can stop the conductive copper socket excessive when pegging graft, the integral mechanical structure of butt joint plays booster action again simultaneously.
Claims (4)
1, bus duct joint, be connected the two ends of bus duct, every line is provided with a pair of connecting plate, separate with the joint dividing plate that insulate between every pair of connecting plate, connecting plate and joint dividing plate are stacked together, the two sides clamps with card pressing plate and screw-nut, it is characterized in that connecting plate adopts multilayer soft copper row stack to constitute, and adds guide edge in the top of connecting plate and the edge at two ends simultaneously.
2,, it is characterized in that adding bound edge in the edge of joint dividing plate according to the described bus duct joint of claim 1.
3, according to the described bus duct joint of claim 2, it is characterized in that the triangle that is shaped as of dividing plate top and two ends bound edge, following bound edge is plate shaped.
4,, it is characterized in that soft copper row's the number of plies is four layers according to claim 1,2 or 3 described bus duct joints.
