In the extra high voltage line engineering, to save steel and the reduction cost except dwindling the tower head size, the 500kV circuit adopts rigid jumper to satisfy requirement of engineering usually.Because rigid jumper is reasonable to the distance that iron tower ground connection keeps, thereby reduced the sag of wire jumper, simultaneously, because the rigidity of wire jumper, under the wind-force effect, its rocking tendency can significantly reduce, and therefore can shorten the length of cross-arm.Existing hard jumper wire construction mainly contains two kinds of cage wire jumper and aluminum pipe formula wire jumpers.Aluminum pipe formula wire jumper has good and economic, has obtained using widely in the ultra high voltage engineering.Aluminum pipe formula wire jumper mainly is made up of several sections such as: aluminum pipe, aluminium tube joint, aluminum pipe conductor spacer, suspention conductor spacer, weight sheet, the female terminal drainage gold utensil of pipe, drainage wire clamp, wire jumper insulator strings.
Ultra high voltage engineering wire jumper distance is big, and the aluminum pipe that needs reaches 16 meters at least.Single transportation is very difficult, thereby it is designed to segmentation, as 16 meters long aluminum pipes being divided into 6 meters and 10 meters two sections interlaced arrangement, connects with aluminium tube joint then.Find that through the long-term a large amount of test of the inventor there are the problems of slippage in this aluminium tube joint, the utility model has designed a kind of not only machinery and excellent electrical properties for this reason, and can effectively prevent the be in operation pipe female joint of slippage of aluminum pipe.
The utility model content
The purpose of this utility model provides a kind of aluminium tube joint for the aluminum pipe wire jumper, and this aluminium tube joint comprises nipple and coupling, makes the aluminium tube joint Stability Analysis of Structures, has improved machinery and electric property greatly.
For achieving the above object, the present invention by the following technical solutions: a kind of aluminium tube joint of antiskid aluminum pipe wire jumper, described joint comprises coupling and nipple; Described nipple is the pipe fitting that is provided with annular boss; The inwall of described coupling is circular arc, and described coupling is provided with corresponding connecting hole; Described coupling inside arranges annular slot.
The aluminium tube joint of a kind of antiskid aluminum pipe wire jumper that the utility model provides, described connecting hole are perpendicular to the coupling surface, and symmetrical distribution is arranged on the coupling both sides.
The aluminium tube joint of a kind of antiskid aluminum pipe wire jumper that the utility model provides adopts bolt to connect the lip-deep connecting hole of described coupling, and described bolt is that regular screw threads, Major Diam are 10mm.
The aluminium tube joint of another preferred a kind of antiskid aluminum pipe wire jumper that the utility model provides, described nipple external diameter are than the little 2mm of aluminum pipe internal diameter, and in the tolerance control ± 0.2mm, the nipple wall thickness is 9～10mm.
The aluminium tube joint of a preferred a kind of antiskid aluminum pipe wire jumper again that the utility model provides, described coupling internal diameter are greater than in aluminum pipe external diameter 0.2～0.5mm, and described coupling inwall is that electric contact-making surface roughness is not more than 12.5 μ m.
The aluminium tube joint of another preferred a kind of antiskid aluminum pipe wire jumper that the utility model provides, described coupling surface is rounding off type profile, the position after described bolt is installed is lower than bolt hole.
The aluminium tube joint of another preferred a kind of antiskid aluminum pipe wire jumper that the utility model provides, described boss is arranged on the nipple centre position.
The aluminium tube joint of another preferred a kind of antiskid aluminum pipe wire jumper that the utility model provides, described circular arc are 2 or 4 compositions.
Because the beneficial effect that has adopted technique scheme, the utility model to obtain is:
1, aluminium tube joint Stability Analysis of Structures in the utility model, machinery, electric property is good;
2, in the utility model aluminium tube joint and aluminum pipe at the scene easy for installation, the interchangeability universal performance is good.
3, the draw-in groove in the middle of the coupling and aluminum pipe top welding flange formation structure is locked in the utility model, is difficult for taking place the situation of aluminum pipe slippage.
4, the utility model China and foreign countries joint surface rounding off type profile, the position after bolt is installed is lower than bolt hole, avoids the generation of corona;
The position was certain when 5, the boss of nipple was guaranteed the aluminium tube joint integral installation in the utility model, can not be offset.
