[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] It should be noted that the terms "above", "one end", "upper", etc. used in this article to indicate the orientation or position relationship is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Similar expressions are only for the purpose of explanation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] Embodiment 1:

[0031] like Figure 1 The busbar clamp shown is used to electrically connect a first busbar and a second busbar of a T-connection, wherein the axes of the first busbar and the second busbar are perpendicular and the whole is arranged in a T-shape. The busbar clamp includes a pair of wire clamps 1 arranged in mirror symmetry.

[0032] The wire clamp 1 is conductive, and preferably the entire wire clamp 1 is made of conductive material. It comprises a first semi-arc plate 11 and a second semi-arc plate 12 that are fixedly connected, and preferably the first semi-arc plate 11 and the second semi-arc plate 12 are integrally formed.

[0033] The two first semi-arc plates 11 are fixedly connected by the first fastening component 3 to hold the circumference of the first tube busbar. The inner surface of the first semi-arc plate 11 is a semicircular curved surface, which is clamped to the first tube busbar by the first fastening component 3.

[0034] The two second semi-arc plates 12 are fixedly connected by the second fastening member 4 and then covered at one end of the second tube busbar. The two second semi-arc plates 12 are fixedly connected by the second fastening member 4 to form a cavity as a whole, and the cavity can clamp the end of the second tube busbar under the action of the second fastening member 4.

[0035] The openings of the first semi-arc plate 11 and the second semi-arc plate 12 can be smaller than the corresponding diameters of the first tube busbar and the second tube busbar, so as to facilitate the first tube busbar and the second tube busbar to be inserted into the first semi-arc plate 11 and the second semi-arc plate 12.

[0036] When in use, the two conductive bodies, the first semi-arc plate and the second semi-arc plate, do not need to be fixed by a pressure cover, but are assembled by the second fastening component 4 and the first fastening component 3.

[0037] Compared with traditional products, the advantage of this tubular busbar clamp is that it significantly improves the conductivity. In overseas markets, due to the small conductive contact surface but the requirement for a large conductivity, traditional products often cannot meet the design requirements. Figure 4-5 Compared with the prior art shown in the figure, the non-conductive gland is not used. Instead, it is mainly composed of two conductive bodies, the first half arc plate and the second half arc plate, which conduct electricity at the same time, and the amount of conductivity is significantly increased compared with traditional products. In the construction of the power system, the connection between the busbar and the disconnector is a key link. The busbar clamp of this embodiment realizes the combination of the first half arc plate and the second half arc plate as two conductive bodies.

[0038] Embodiment 2:

[0039] Based on Example 1, see Figure 4 The second semi-arc plate 12 shown has a semi-arc surface for surrounding the circumference of the second tube busbar and a top surface for surrounding the axial end surface of the second tube busbar on its inner surface. The shape of the top surface is semicircular as a whole, so that when the two second semi-arc plates 12 are opposite to each other, they are covered on the axial end surface of the second tube busbar. When the two semi-arc surfaces are opposite to each other, the second tube busbar can be clamped under the action of the second fastening component 4.

[0040] Specifically, the second semi-arc plate 12 is provided with protrusions 121 on both radial sides of the second tube busbar, and the second fastening component 4 includes a plurality of second bolts and a second nut. The second bolt passes through the two protrusions 121 on the same radial side of the second tube busbar and is then sleeved with the second nut. The protrusions 121 are provided at the edge of the circumferential end of the second semi-arc plate 12 and extend along both radial sides of the second tube busbar, thereby providing a mounting base for the second fastening component 4.

[0041] Embodiment three:

[0042] Based on the first embodiment, the first semi-arc plate 11 includes an arc body 111 which is semi-arc in shape as a whole, a connecting body 112 connecting the circumferential end of the arc body 111 and the second semi-arc plate 12, and the connecting body 112 is flat in shape as a whole and extends along the axial direction of the second tube busbar.

[0043] Preferably, the connecting body 112 is provided with reinforcing ribs 5 connecting the first half arc plate 11 and the second half arc plate 12. Adding reinforcing ribs 5 at weak points improves product strength and stability in the case of crosswind and vibration of the tube busbar itself.

[0044] Specifically, the first fastening component 3 includes a plurality of connecting bolts and connecting nuts, and the connecting bolts and connecting nuts fasten the two connecting bodies 112 together.

[0045] The first fastening member 3 further comprises a plurality of first bolts and first nuts, which fasten together the ends of the two first semi-arc plates 11 away from the connecting body 112. A through hole is provided at the end of the first semi-arc plate 11 away from the connecting body 112 for the first bolts to pass through.

[0046] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
