Description

Technical Field

[0001] The utility model relates to the technical field of busbars, in particular to a new energy high-voltage Busbar based on a copper-aluminum composite plate. Background Art

[0002] The busbar refers to the copper or aluminum busbar that connects the main switch in the cabinet to the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to be used as a conductor. It is the name of the conductive material on the power distribution equipment. The material is copper (equivalent to wire), there is no insulation layer, and the outside is painted with color paint indicating the phase sequence. It is mainly used for indoor transformers to distribution cabinets and then to the main power switch and then to each branch switch. In the field of new energy vehicles, high-voltage power distribution requires the use of busbars for electrical power connection;

[0003] Announcement No. "CN217061476U" provides a special-shaped copper busbar, including a busbar body, the busbar body having a vertical surface, the upper and lower ends of the vertical surface respectively extending to the same side to form an upper horizontal surface and a lower horizontal surface, the side of the upper horizontal surface away from the vertical surface has a first folded edge facing the lower horizontal surface, and the side of the lower horizontal surface away from the vertical surface has a second folded edge facing the upper horizontal surface. This solution has a simple structure and is easy to use. The current carrying capacity under the same cross-section is much higher than that of a rectangular copper busbar, and can well meet higher current carrying requirements;

[0004] However, the above solution still has the following defects:

[0005] Since the busbar body is made of pure copper, which has low hardness, and the cross-section of the busbar body is roughly C-shaped, the busbar body will be deformed when squeezed during transportation, which makes the busbar body unable to be used normally. Utility Model Content

[0006] The purpose of the utility model is to provide a new energy high-voltage Busbar based on a copper-aluminum composite plate to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A new energy high-voltage busbar based on a copper-aluminum composite plate comprises a busbar body, an insulating support block is arranged on the inner wall of the busbar body, support feet are obliquely extended from the top and bottom of the insulating support block, a plane is arranged at one end of the support foot, the plane abuts against the inner wall of the busbar body, the insulating support block is perpendicular to the busbar body, and the insulating support block can slide at any level on the inner wall of the busbar body.

[0009] Preferably, the busbar body is composed of two layers of copper plates and an aluminum plate between the two layers of copper plates.

[0010] Preferably, a support platform is integrally formed on one side of the insulating support block, and one side of the support platform extends into the notch of the busbar body.

[0011] Preferably, one side of the support platform extends from the inside of the busbar body to one side of the busbar body, and protrusions extend from the top and bottom of the support platform.

[0012] Preferably, the side surface of the protrusion is in contact with the side surface of the busbar body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model vertically arranges an insulating support block inside the special-shaped busbar body, which can play an overall supporting role from the inside of the busbar body, and through the arrangement of the support platform on the insulating support block, it can support from the notch of the busbar body, thereby increasing the anti-extrusion capacity of the busbar body. At the same time, since the busbar body is composed of two layers of copper plates and the aluminum plate between the two layers of copper plates, the overall hardness of the busbar body after the composite is greatly increased, further increasing the overall anti-extrusion capacity, and preventing the busbar body from being unusable due to extrusion deformation during transportation.

The insulating support block 2 can slide horizontally on the inner wall of the busbar body 1 at any level.

Finally, the busbar body 1 is composed of two layers of copper plates 5 and aluminum plates 6 in the two layers of copper plates 5. Through the setting of the aluminum plate 6, the overall hardness of the busbar body 1 is increased, which can further improve the anti-deformation ability of the busbar body 1.
