Abstract
The utility model provides an end connector of a high-fit tubular bus, wherein one end of the end connector is a connecting pipe of a metal cylinder, and the other end thereof is a connecting plate; the connecting plate is evenly provided with 2-6 screw holes; the connecting pipe is connected with the connecting plate into a whole though a middle transition cone; and the overall length of the connecting pipe is provided with 2-6 axial opening grooves which are evenly distributed on the transverse sectional plane, wherein the length of each opening groove is equal to each other, the lengths are 110-150mm, and the widths are 1-3mm. The middle transition cone is provided with a breathing hole, wherein the inclined angle between the axis of the hole and the plane of the connecting plate is 40-50 degrees, and the diameters of the hole are 10-14mm. The inner hole of the connecting pipe and the two planes of the connection pate are refined. The end connector has integrated structure, beautiful appearance, large contact surface and good electric conduction performance, is conveniently installed as the end connecting pipe adopts the opening grooves, achieves high fit effect after machining the inner hole, and reduces the running temperature of the tubular bus as the breathing hole at the middle part can circulate the air in the pipe.
Description
Technical field
The utility model relates to power equipment, i.e. the identical tube type bus end connector of the height that uses in the transformer station.
Background technology
In recent years, in transformer station, use tube type bus to be promoted gradually, it is compared with traditional rectangular bus bar has multiple advantages: electric insulating quality is strong, ampacity is big, kelvin effect is low, power loss is little, the temperature rise performance is good, mechanical strength is high, anti-electric vibratility is strong, applied widely, has become the traditional rectangular bus bar and the regeneration product of aerial cable.
In the installation of tube type bus, the joint of the end connector that is absolutely necessary, the first end of termination is the tube connector that connects tube type bus, and the other end is the connecting plate that connects other electric conductors, and the joint of tube type bus has two kinds of modes at present, the one, in connect mode, with the end that junction block inserts tube type bus, there is axial open seam the tube type bus end, and the external diameter of tube connector equates with the internal diameter of tube type bus, because contact area is little, so temperature rise is higher during work; The 2nd, external mode, the external diameter of tube connector internal diameter and tube type bus equates, connect one or two arranged on the tube wall (promptly being two slices watts of shape splits) axial elongated open seam, the other engaging lug that is fixed with of open seam, several screws are arranged on the engaging lug, tube type bus is inserted in the tube connector and with screw tube connector and tube type bus are fixed, its shortcoming is that profile is not attractive in appearance, the more important thing is and set up engaging lug, screw, cause phase spacing to diminish.
Summary of the invention
For overcome the tube type bus joint in connect little, the temperature rise of mode contact-making surface, the shortcoming that external mode profile is not attractive in appearance, phase spacing is little the utility model proposes a kind of new design of high identical tube type bus end connector.
This height tube type bus end connector that coincide, one end is the tube connector of metallic cylinder, and the other end is a connecting plate, evenly is furnished with 2～6 screws on the connecting plate, tube connector and connecting plate are connected as a single entity by the middle transition cone, it is characterized in that, on the total length of tube connector, have 2～6 axial open slots, on the cross section, open slot is equally distributed, the equal in length of each open slot, long 110～150mm, opening groove width 1～3mm.
On the middle transition cone spiracle is arranged, the axis in hole and connecting plate plane included angle are 40～50 °, aperture 10～14mm.
Carried out fine finishining at the endoporus of tube connector and two planes of connecting plate.
In construction, in the end insertion end joint of the tube type bus that needs are connected, hold tightly with special-purpose anchor ear, doing insulation again and handling, at the other end that connecting plate and other electric conductors is good with bolt.
The utility model has the advantages that: structure is an integral type, good looking appearance, contact area is big, conduct electricity very well, the termination tube connector adopts the form of open slot, and is easy for installation, after the endoporus processed, reached the effect that is identical, the spiracle at the middle part inner air tube that can circulate, thus reduce the tube type bus operating temperature.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail as follows:
In Fig. 1, Fig. 2 and Fig. 3, this height tube type bus end connector that coincide, an end is the tube connector 1 of metallic cylinder, the other end is a connecting plate 2, evenly be furnished with 4 screws 3 on the connecting plate 2, tube connector 1 and connecting plate 2 are connected as a single entity by middle transition cone 4, have 4 axial open slots 5 on the total length of tube connector 1, in Fig. 3, open slot 5 is equally distributed, the equal in length of each open slot 5, long 130mm, opening groove width 2mm.
Carried out fine finishining at the endoporus of tube connector 1 and two planes of connecting plate 2.
Claims (3)
1. the high tube type bus end connector that coincide, one end is the tube connector of metallic cylinder, and the other end is a connecting plate, evenly is furnished with 2～6 screws on the connecting plate, tube connector and connecting plate are connected as a single entity by the middle transition cone, it is characterized in that, on the total length of tube connector, have 2～6 axial open slots, on the cross section, open slot is equally distributed, the equal in length of each open slot, long 110～150mm, opening groove width 1～3mm.
