Abstract
A bus connector of a high voltage switch cabinet belongs to the technical field of power transmission and distribution. The bus connector comprises a connecting bolt and a hexagon bolt with a cylindrical wire connector on the head, wherein the stud part of the hexagon bolt is matched with the internal screw thread in a blind hole on the end of an insulator conductive core, one end of the cylindrical wire connector which is connected with the head of the hexagon bolt is in the cylindrical shape, the other end of the cylindrical wire connector which is connected with the bus of the high voltage switch cabinet is in the semi-cylindrical shape, and the screw thread matched with the connecting bolt is arranged in the middle part of the rectangular surface of the semi-cylindrical shape. One end of the cylindrical wire connector which is connected with the bus of the high voltage switch cabinet is in the semi-cylindrical shape, so that the surface of the overlap part is smooth, wherein the overlap end is formed by overlapping the semi-cylindrical end of the wire connector with the semi-cylindrical end of the bus of the high voltage switch cabinet, so as to effectively avoid the point discharge phenomenon and improve the reliability of the high voltage switch cabinet, and moreover the appearance of the bus connector is beautiful, and the bus connector facilitates the installation of an insulator sheath.
Description
Technical field
The utility model relates to a kind of busbar joint for the conductive cores of the bus of high-tension switch cabinet and insulator inside is linked together, and belongs to power transmission and distribution technical field.
Background technology
Bus in high-tension switch cabinet is to be connected with external cable by being arranged on the conductive cores of the insulator inside on switch cubicle sidewall, and the conductive cores of insulator is connected with bus in cabinet by busbar joint.Existing busbar joint is all that head is with the hexagon-headed bolt of cylindric power lug, double-screw bolt is partly screwed in the screwed hole of insulator conductive cores, fastening with connecting bolt after the overlap joint of the termination of bus in cylindric power lug and cabinet, finally put the connection that insulator sheath completes bus.The shortcoming of this method of attachment is that the part of busbar shiplap joint in cylindric power lug and cabinet is thicker, the neither installation that is also unfavorable for insulator sheath attractive in appearance, the more important thing is that overlapping part surface is not round and smooth, easily cause point discharge, the reliability of the high-tension switch cabinet greatly having reduced.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of wiring attractive in appearance, easy for installation and can effectively prevent the high-tension switch cabinet busbar joint of point discharge.
Problem described in the utility model realizes with following technical proposals:
A kind of high-tension switch cabinet busbar joint, formation comprises that connecting bolt and head are with the hexagon-headed bolt of column power lug, double-screw bolt part and the internal thread in the blind hole of insulator conductive cores end of described hexagon-headed bolt match, one end that described column power lug is connected with the head of hexagon-headed bolt is cylindric, the one end being connected with high-tension switch cabinet bus is semi-cylindrical, at the rectangular surfaces middle part of semicolumn, is provided with the screwed hole matching with connecting bolt.
Above-mentioned high-tension switch cabinet busbar joint, described connecting bolt is hexagon socket head cap screw, its length is less than the diameter of column power lug.
One end that power lug of the present utility model is connected with high-tension switch cabinet bus is semi-cylindrical, the overlap joint rear surface, semi-cylindrical termination of it and high-tension switch cabinet bus is round and smooth, not only effectively avoided the generation of point discharge phenomenon, improved the reliability of high-tension switch cabinet, and good looking appearance, be convenient to the installation of insulator sheath.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that head is with the outline drawing of the hexagon-headed bolt of column power lug;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the right view of Fig. 3;
Fig. 5 is assembling schematic diagram of the present utility model;
Fig. 6 is A-A cutaway view.
In figure, each list of reference numerals is: 1, screwed hole, 2, hexagon-headed bolt, 3, bus, 4, insulator sheath, 5, busbar joint, 6, insulator conductive cores, 7, insulator, 8, switch cubicle sidewall, 9, connecting bolt.
Embodiment
Referring to Fig. 1～Fig. 6, by head, hexagon-headed bolt 2 and the connecting bolt 9 with column power lug forms the utility model, double-screw bolt part and the internal thread in insulator conductive cores 6 end blind holes of hexagon-headed bolt 2 match, column power lug is coaxial with hexagon-headed bolt 2, its one end being connected with the head of hexagon-headed bolt 2 is cylindrical, the one end being connected with high-tension switch cabinet bus 3, for half-cylindrical, is provided with the screwed hole 1 matching with connecting bolt 9 in semi-cylindrical rectangular surfaces.During wiring, the end machining of high-tension switch cabinet bus 3 is become to half-cylindrical and stamps bolt hole, the half-cylindrical termination of the half-cylindrical termination of bus 3 and column power lug is fastened, then connecting bolt 9 is screwed in to the screwed hole 1 of column power lug through after the bolt hole of bus 3, then put the connection that insulator sheath 4 completes bus 3.
As seen from Figure 6, after the half-cylindrical termination of the half-cylindrical termination of bus 3 and column power lug fastens, close to cylindrical, connecting bolt 9 is positioned at the counterbore of bus 3, so joint surface is rounder and more smooth, not only attractive in appearance but also be not easy to occur point discharge.The installation of insulator sheath 4 is also very smooth and easy, can not be subject to the obstruction of joint.
Claims (2)
1. a high-tension switch cabinet busbar joint, it is characterized in that, it comprises that connecting bolt (9) and head are with the hexagon-headed bolt (2) of column power lug, double-screw bolt part and the internal thread in the blind hole of insulator conductive cores (6) end of described hexagon-headed bolt (2) match, described column power lug is cylindric with one end that the head of hexagon-headed bolt (2) is connected, the one end being connected with high-tension switch cabinet bus (3) is semi-cylindrical, at the rectangular surfaces middle part of semicolumn, is provided with the screwed hole (1) matching with connecting bolt (9).
2. a kind of high-tension switch cabinet busbar joint according to claim 1, is characterized in that, described connecting bolt (9) is hexagon socket head cap screw, and its length is less than the diameter of column power lug.
