Abstract
The utility model relates to a pipe generating line, especially a pipe generating line who is connected with banded power transmission line belong to electric power tech and equipment field. A pipe generating line, includes pipe form main part, its characterized in that: the flat back pipe wall of tip system of pipe form main part forms at least one and connects the plane, be equipped with a plurality of connecting bolt holes on the connection plane. The flat rear end face of tip system of pipe form main part forms the runway form of connecting on double -phase right parallel connection plane through two transition circular arcs. It presses the banded power transmission line contact of holding to link firmly with the plane clamp plate to connect the plane. The connection plane and the banded power transmission line of pipe generating line pipe form main part tip pass through the plane laminates with planar contact, compares and changes the cooperation in the arc to area of contact is many, and contact resistance is showing and reduces, in addition, will connect plane, banded power transmission line, the fastening of plane clamp plate through the bolt, and mechanical strength is big.
Description
Technical field
The utility model relates to a kind of pipe bus, and especially a kind of pipe bus be connected with stripline transmission line, belongs to power technology and apparatus field.
Background technology
Usually, the electric power that power plant produces needs to deliver in user family through primary substation, overhead transmission line, step-down substation, low-voltage distributing line.And along with national economy increase fast, urban construction develop rapidly, enterprise, electricity consumption of resident straight line rise, cause the main transformer capacity of transformer station constantly to increase thus, the rated current of transformer low voltage outgoing line side also increases thereupon.In order to meet the transmission requirement of large operating current, buses of insulation tubes relies on the advantages such as its ampacity is large, mechanical strength is high, perfect heat-dissipating to instead of traditional rectangular bus bar.
Between different devices, need different circuits to form transmitting loop.In some certain connection points, need pipe bus and the stripline transmission line such as copper strips or aluminium strip to couple together.Existing connected mode mainly contains following several: one, as shown in Figure 4, soft copper band is attached to pipe end of bus bars and uses anchor ear fastening.This syndeton mechanical strength is in the axial direction weak, connects insecure.Two, as shown in Figure 5, soft copper band is attached to pipe end of bus bars, and compresses with arc pressuring plate, make its pipe bus of fitting, then by bolt by fastening to pipe bus, soft copper band, arc pressuring plate three.Adopt in this way, need to arrange circle bolt and an arc pressuring plate around pipe bus circumference, complicated operation, mechanical strength is lower.
Utility model content
The purpose of this utility model is: for the problems referred to above, provides that a kind of mechanical strength is high, profile is carefully and neatly done, the pipe bus be connected with stripline transmission line of easy accessibility.
In order to reach above object, the technical solution of the utility model is as follows: a kind of pipe bus, comprise circular tube shaped main body, it is characterized in that: the flat rear tube wall of end system of described circular tube shaped main body forms at least one and connects plane, and described connection plane is provided with some link bolt hole.
Preferably, the flat rear end face of end system of described circular tube shaped main body forms the runway shape that two relative parallel connection planes are connected by two transition arcs.
Preferably, described connection plane contacts with the stripline transmission line of flat platen pressure holding and is connected.
Preferably, the inside and outside two sides of described connection plane contacts with inside and outside stripline transmission line respectively, described inside and outside stripline transmission line respectively by inner plane pressing plate and the pressure holding of outerplanar pressing plate, by securing member be connected plane and be connected.
At least one connection plane of the flat rear formation of circular tube shaped busbar body end system, contacts with the stripline transmission line of flat platen pressure holding and is connected.The contact of plane and plane, more easily coordinates compared to arc, and contact area is many, and contact resistance significantly reduces.In addition, connect plane and be provided with link bolt hole, connection plane, flat platen, stripline transmission line are fastenedly connected by securing member, mechanical strength is high.
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 utility model embodiment one and stripline transmission line syndeton schematic diagram;
Fig. 2 is that Figure 1A-A locates generalized section;
Fig. 3 is the utility model embodiment one pipe end of bus bars structural representation;
Fig. 4 is prior art pipe bus and stripline transmission line hood type connection diagram;
Fig. 5 is prior art pipe bus and stripline transmission line by the fastening connection diagram of arc pressuring plate.
In figure: in 1-circular tube shaped main body, 21-, in stripline transmission line, the outer stripline transmission line of 22-, 3-anchor ear, 4-arc pressuring plate, 5-bolt, 6-link bolt hole, 71-inner plane pressing plate, 72-outerplanar pressing plate, 81-, connection plane, 82-connect plane, 9-transition arc outward.
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 Figures 2 and 3, the flat rear tube wall of end system of circular tube shaped main body 1 is formed in two and connects plane 81 and be connected plane 82 outward with two, and four connect planes and are parallel to each other.The flat rear end face of end system of circular tube shaped main body 1 forms the runway shape that two relative interior parallel connection planes 81 are connected by two transition arcs 9.Each connects plane and is provided with two rows totally six link bolt hole 6.As depicted in figs. 1 and 2, interior connection plane 81, outer connection plane 82 contact with outer stripline transmission line 22 with interior stripline transmission line 21 respectively, and, inside and outside stripline transmission line is respectively by inner plane pressing plate 71 and outerplanar pressing plate 72 pressure holding, and flat platen, stripline transmission line and connection plane are connected by bolt 5.Outerplanar pressing plate 72 and inner plane pressing plate 71 are non-ferromagnetic metal pressing plate.Like this, connect plane and stripline transmission line by plane and plane bonded to each other, more easily coordinate compared to arc, easier in operation; And contact area is many, contact resistance significantly reduces; In addition, be fastenedly connected by bolt 5, mechanical strength is large.
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.
