Problems solved by technology

However, the connection of circular busbars is difficult, especially the connection between main busbar and branch busbar (such as T-shaped connection) is very inconvenient, and the contact area is also small, resulting in poor conduction and cannot be used in large-capacity switch cabinets.

Embodiment Construction

[0016] see figure 1 . The switchgear of the prior art adopts the rectangular busbar as shown in the figure, wherein 11 is a horizontal busbar, 12 is a branch busbar, both of which are rectangular, connected together with screws 13, which can ensure the connection strength and contact area of ​​the busbar.

[0017] see figure 2 . The cross-section of the busbar 21 used in the present invention is circular, and the two sections of busbars are connected by a conductive coupler 24, and the two sections of busbars are respectively inserted into the two coupling ends of the coupler and are in close contact with the coupler; There is a compression nut 23 on the outside of each end to compress the connecting end and the busbar; there is also a locking nut 22 at the outer end of the compression nut to prevent the compression nut from coming out.

[0018] see image 3 , Figure 4 . The connector 24 of this embodiment is a straight-through type, with two connecting ends 241, 242, ...

Abstract

The present invention relates to a high voltage switch cabinet adopting conductor connector, comprising buses whose cross sections are round. The buses are connected through a connector; the connector is made of electric conducting material, which comprises at least two connecting ends; each connecting end is a hollow round tube shape, whose inner diameter is matched with the outer diameter of the bus and the outer wall is provided with screw threads; each connecting end is provided with a compressing nut which is matched with the outer screw thread of the connecting end. The present inventionfurthest saves the space of the switch cabinet, reduces the volume of the switch cabinet, makes the electric fields contribution more rational, improves the insulating capability, and well solves the connecting problem of the buses.

Description

technical field [0001] The invention belongs to the electrical field, and more specifically relates to a high-voltage switchgear for controlling complicated electrical on-off, in particular to a conductor connector for a high-voltage switchgear. Background technique [0002] High-voltage switchgear is a very commonly used switchgear in the field of power transmission and transformation and industrial power consumption. It is mainly composed of a busbar installed in the cabinet and a series of air switches. The busbar is also called busbar and is made of copper, aluminum and other materials with good conductivity. It is used to connect the conductors in the switch cabinet and play the role of transmitting current. The current high-voltage switchgear generally adopts rectangular busbars, that is, the cross-section of the busbars is rectangular, so that the busbars can be connected by screws, which is convenient for connection and has good conduction. The problem is that when ...
