Abstract
The utility model discloses a butt joint tubular busbar, tubular busbar main part including two mutual butt joints, the abutting end of tubular busbar main part docks each other through interior bushing pipe and links firmly, the interval that the pipe wall system of abutting end has at least round circumference to distribute is sunken, the sunken embedding in interval the outer wall of interior bushing pipe. Interior bushing pipe traditional chinese clothing has the stress tube of tight fit with it. The sunken cross section in tubular busbar main part abutting end interval is the polygon at regular polygon or a plurality of angles of circumference even spacing distribution. Under the sunken positioning action in circumference interval, the tubular busbar main part of two butt joints has formed axial and circumference restraint between each other, reliably fixes each other to interior connection structure makes the appearance carefully and neatly done. In addition, because inside and outside material forms the relation of inlaying each other, therefore contact resistance is showing and is reducing, is favorable to the transport of electric current.
Description
Technical field
The utility model relates to a kind of docking tube type bus, for transmission of electricity, belongs to power technology and apparatus field.
Background technology
Tube type bus is a kind of power transmitting device of efficient conveying high-pressure electric current, tube type bus is compared with traditional rectangular bus bar, there are some advantages, such as unit section ampacity is large, kelvin effect good, radiating condition is good, allowable stress is large, span is large, mechanical strength is high, electrical insulation properties is strong, main insulation stability of material is high, insulating process is reasonable.Along with the growth steady fast of national economy, social power consumption linearly rises, and transforming plant main transformer capacity is constantly strengthened, and the rated current of main transformer low-pressure line-outgoing side also increases thereupon, and power department more and more uses tube type bus.
Existing tube type bus transition joint has following several mode: one, hood type joint, as shown in Figure 4, Figure 5, it adopts the copper sheathing 5 with axially open to be enclosed within two tube type bus main body 1 joints, anchor ears 6 and is enclosed within opening copper sheathing 5, is fastened by bolts, reaches the object of permanent joint, but this type of joint surface has projection, easy generation point discharge, and when pipe mother runs, bolt easily loosens, and can cause herein that contact resistance is large; Two, welded fitting is welded by two conductors, makes it fuse into one, although good looking appearance, the conductance of weld declines, and can there is the hidden danger such as heating after energising.In addition, it is complete at the scene that tube type bus connects, and site environment is complicated, and welding can increase difficulty to on-site installation work.
Utility model content
The purpose of this utility model is: for the problems referred to above, provides the docking tube type bus that a kind of mechanical strength is high, profile is smooth.
In order to reach above object, the technical solution of the utility model is as follows: a kind of docking tube type bus, comprise two tube type bus main bodys of mutually docking, the butt end of described tube type bus main body is mutually docked by internal lining pipe and is connected, the tube wall of described butt end is shaped with the spaced depressions of at least one circle circumference distribution, and described spaced depressions embeds the outer wall of described internal lining pipe.Under the positioning action of circumferential spaced depressions, the tube type bus main body of two docking defines each other and axially retrains with circumference, mutually reliable fixing, and interconnect structure makes profile carefully and neatly done.In addition, because inside and outside material forms the relation of inlaying mutually, therefore contact resistance significantly reduces.
It is that friction tight stress tube is with it housed in described internal lining pipe that the utility model further improves.Larger radial pressure can be born like this.
Further, the cross section of described tube type bus main body butt end spaced depressions is regular polygon.
Further, the cross section of described tube type bus main body butt end spaced depressions is the polygonal at the multiple angle of the equidistant distribution of circumference.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the spaced depressions place cross sectional representation of Fig. 1 embodiment;
Fig. 3 is the utility model embodiment two spaced depressions place cross sectional representation;
Fig. 4 is the tube type bus hood type joint design schematic diagram of prior art;
Fig. 5 is the tube type bus hood type joint cross-sectional view of prior art.
In figure: 1-tube type bus main body, 2-internal lining pipe, 3-stress tube, 4-spaced depressions, 5-copper sheathing, 6-anchor ear.
Embodiment
In order to understand the utility model better, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Embodiment one
As shown in Figure 1, dock tube type bus and comprise two tube type bus main bodys 1, internal lining pipe 2 and stress tube 3.The butt end of two tube type bus main bodys 1 is mutually docked by internal lining pipe 2 and is connected, and the tube wall of every root tube type bus main body 1 butt end is shaped with the spaced depressions 4 of three circles circumference distributions.As shown in Figure 2, the cross section of spaced depressions 4 is regualr decagon.Spaced depressions 4 embeds the outer wall of internal lining pipe 2.Friction tight stress tube 3 is with it housed in internal lining pipe 2, larger radial pressure can be born like this.
During assembling, utilize large tonnage pressing machine to extrude and tighten up docking cast busbar joint position, make tube type bus main body 1 and embedded internal lining pipe 2 enclose spaced depressions 4 by six to combine closely, like this, under the positioning action of circumferential spaced depressions 4, the tube type bus main body 1 of two docking defines each other and axially retrains with circumference, mutually reliable fixing, and interconnect structure makes profile carefully and neatly done.In addition, because inside and outside material forms the relation of inlaying mutually, therefore contact resistance significantly reduces, and is conducive to the conveying of electric current.
Embodiment two
As shown in Figure 3, the cross section at spaced depressions place is the polygonal at the equidistant distribution of circumference 12 angles.The present embodiment remainder is with embodiment one.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
Claims (4)
1. a docking tube type bus, comprise two tube type bus main bodys of mutually docking, it is characterized in that: the butt end of described tube type bus main body is mutually docked by internal lining pipe and is connected, the tube wall of described butt end is shaped with the spaced depressions of at least one circle circumference distribution, and described spaced depressions embeds the outer wall of described internal lining pipe.
