Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of high-voltage enclosed busbar bridge structure, specifically a high-voltage enclosed busbar bridge structure made of aluminum material that meets the high protection level. Background Technology
[0002] As an indispensable connection device between switchgear and transformers, busbar bridges rely on internal conductor connections to realize current transmission between switchgear and transformers. Under the influence of certain factors (such as dust, rain, and humidity), in order to ensure the reliable operation of complete sets of electrical equipment, the busbar bridge structure composed of ordinary splicing and welding cannot meet the required protection level requirements. Utility Model Content
[0003] The purpose of this utility model is to improve upon the shortcomings of existing technologies by providing a high-protection-level aluminum high-voltage enclosed busbar bridge that is lightweight, easy to process, and easy to dissipate heat.
[0004] The purpose of this utility model is achieved as follows: a high-protection-level aluminum high-voltage enclosed busbar bridge, comprising a housing, characterized in that the housing is made of aluminum, including two side plates and two reinforcing ribs, the side plates having an inverted U-shaped cross-section, the top edge width of the side plates being less than the bottom edge width, the bottom edges of the two side plates being joined and fixed together to form the bottom of the housing, an opening being formed between the two top edges, and a reinforcing rib being fixed on each side of the opening to form an inspection port, at least one mounting plate being fixed on the inner plane of the bottom of the housing, each mounting plate fixing a set of insulators, a grounding bracket being fixed at each of the four corners of the bottom of the housing, a top cover fixing bracket being fixed on the top surface of the side plates, and a rainproof inspection cover being fixed to the top cover fixing bracket by bolts and covering the inspection port and the upper surface of the housing.
[0005] Compared with existing technologies, this utility model has the following significant features and positive effects: The utility model uses two side plates and two reinforcing ribs welded together to form the shell. High-strength, high-precision welding ensures a high protection level. The mounting plate and grounding bracket are welded and fixed inside the shell. The rainproof top cover is not directly fixed to the shell, but indirectly fixed to the shell through a top cover fixing bracket. Multiple layers of protection improve the protection level and avoid the risk of external water leakage if the rainproof top cover is directly fixed to the shell. The shell of the enclosed busbar bridge is constructed entirely of welded aluminum plates. The non-magnetic material also reduces eddy currents, and good heat dissipation prevents high internal temperatures caused by the high protection level. With a high protection level (meeting IP55), simple structure, few components and easy processing, it is welded into one piece without the need for on-site assembly of the shell, reducing the burden of on-site installation. It is made of aluminum plate, which is lightweight, has good heat dissipation performance, is corrosion resistant and relatively economical in cost. The shell-to-shell and shell-to-rainproof top cover are all connected by single-sided self-adhesive sealing strips, which meet the design concept and usage requirements of high protection level.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0012] A high-protection-level aluminum high-voltage enclosed busbar bridge, such as Figure 1 , Figure 2 , Figure 3 , Figure 4The shell is made of aluminum and includes two side plates 2 and two reinforcing ribs 1. The side plates 2 have a U-shaped cross-section tilted at 90° with openings at both ends. The top edge of the side plate 2 is narrower than the bottom edge. The bottom edges of the two side plates 2 are welded together to form the bottom of the shell. Since the width of the two top edges is narrower than the width of the bottom edges, an opening is formed between the two top edges. A reinforcing rib 1 is welded to each side of the opening to form an inspection port. The reinforcing rib 1 and the side plates 2 have upturned edges at the inspection ports. Single-sided self-adhesive sealing strips 7 are provided at both ends of the shell and around the inspection ports. The height of the single-sided self-adhesive sealing strips is 1-2mm higher than the top cover fixing bracket, which will ensure that the rainproof top cover 5 fits tightly with the shell inspection port to prevent moisture from entering. At least one mounting plate 3 is fixed on the inner surface of the bottom of the shell. The number and position of the mounting plates 3 are adjustable according to the project. Each mounting plate 3 is fixed with a set of insulators. A grounding bracket 6 is fixed at each of the four corners of the bottom of the shell. The position of the grounding bracket 6 can be adjusted according to the length of the grounding wire. Six sets of round holes are opened on the top surface of the side plate 2. The top cover fixing bracket 4 is fixed to the top of the side plate 2 by stainless steel blind rivets and both sides are coated with high temperature resistant sealant. Each top cover fixing bracket 4 has a hexagonal hole. Stainless steel rivet nuts are fixed to the top cover fixing bracket 4 by riveting. The rainproof maintenance cover 5 is fixed to the stainless steel rivet nuts on the top cover fixing bracket 4 by stainless steel screws with PVC waterproof washers. The rainproof maintenance cover 5 has flanges on both sides of the shell opening, which can be used to cover the inside of the shell to form a high-protection level enclosed busbar bridge.
