Abstract
Description
Technical Field
[0001] The utility model relates to the field of power system application equipment, specifically a bus bridge for medium-voltage complete switchgear with a voltage range of 7.2 kV to 40.5 kV. Background Art
[0002] In recent years, with the continuous progress of technology and the increasing demand for national power equipment, the usage of bus bridges used in conjunction has also increased significantly. However, due to the complex working conditions at the installation site, there are a wide variety of bus bridges. Most bus bridges are processed from ordinary steel and then painted for surface treatment. Not only is the self-weight of the bridge heavy, making installation inconvenient, but also its weather resistance and corrosion resistance are poor. At the same time, the magnetic permeability of ordinary steel is large, resulting in strong magnetic induction and increased eddy current loss. All of the above may cause equipment failures of the bus due to heating and electromagnetic loss.
[0003] Therefore, based on the above problems, the utility model provides a bus bridge for switchgear. Summary of the Utility Model
[0004] To solve the above deficiencies in the prior art, the utility model provides a bus bridge for switchgear.
[0005] The utility model adopts the following technical solutions:
[0006] A bus bridge for switchgear consists of a metal outer shell frame, a bus, a heat shrinkable sleeve, an insulator, a bus clamp, and an installation bracket.
[0007] The bus bridge is installed on the top of the switchgear. Along the path of the bus, a metal outer shell frame is installed around the bus. Both ends of the installation bracket are installed on the metal outer shell frame. One end of the insulator is installed on the installation bracket, and the other end is connected to the bus clamp. After the bus is sleeved with a heat shrinkable sleeve, it passes through the bus clamp to achieve the connection between the bus and the metal outer shell frame.
[0008] Further, the material of the metal outer shell frame 1 is aluminum alloy.
[0009] Further, the metal outer shell frame 1 is set as a frame type and is formed by connecting multiple profiles with screws.
[0010] Further, the material of the installation bracket 6 is aluminum alloy, which is set as a long strip type, and two plates are respectively arranged at both ends for connecting the metal outer shell frame 1.
[0011] Compared with the prior art, the technical effect of the utility model lies in: reasonable structural design, good heat dissipation and magnetic isolation performance, and high economic practicality. Brief Description of the Drawings
