Description

Technical Field

[0001] The utility model relates to the technical field of dense bus ducts, and particularly relates to a dense bus duct structure. Background Technique

[0002] The dense bus duct has the characteristics of large current capacity, good quality and safety performance, etc. It is widely used in the power supply system. The dense bus duct structure is a commonly used type of power transmission and distribution structure. However, there are still some defects in the actual use of the dense bus duct structure.

[0003] The dense bus duct structure often only arranges heat dissipation fins on the outer wall of the shell to increase the heat conduction area and achieve the effect of improving the heat dissipation effect. This method has the defects of being far away from electrical components and having poor heat conduction and heat dissipation effects. Moreover, the conductor copper bar structure is simple, without a cable fixing structure, and it is not easy to realize the rapid assembly of the external connecting cable on the conductor copper bar, which leads to inconvenient operation of the device. Based on this, we propose a new type of dense bus duct structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dense bus duct structure to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A dense bus duct structure, including a shell and an assembly substrate. Both sides of the shell are clamped with second side covers. A reserved installation cavity matching the second side covers is arranged inside the shell. Second copper alloy heat conduction tubes and first copper alloy heat conduction tubes are uniformly welded inside the reserved installation cavity. One end of the second copper alloy heat conduction tube is welded with a filter air guide component penetrating the shell. The assembly substrate is welded on one side of the first copper alloy heat conduction tube. First side covers are installed on both sides of both ends of the shell. Conductor copper bars are uniformly fixed on the shell between adjacent first side covers. Insulated branch interfaces are arranged on the conductor copper bars. A conductive contact block and a pressing plate are respectively installed at the top and bottom inside the insulated branch interface. Composite rubber springs are uniformly connected between the pressing plate and the insulated branch interface. Heat dissipation fins are uniformly welded on both the shell and the second side covers.

[0006] Preferably, 4 first side covers are provided, 2 second side covers are provided. Rubber insulation layers are vulcanized and connected to the outer side walls of the first side covers and the second side covers, so as to improve the anti-slip insulation effect of the first side covers and the second side covers.

[0007] Preferably, a first locking piece matching the shell is arranged on the first side cover. A screw is arranged between the first locking piece and the shell, so as to facilitate the disassembly, installation and maintenance between the first side cover and the shell.

[0008] Preferably, second locking pieces are evenly welded on both the second side cover plate and the housing, and screws are arranged between adjacent second locking pieces, facilitating disassembly, assembly, and maintenance between the second side cover plate and the housing.

[0009] Preferably, the interiors of the second copper alloy heat conduction tube and the first copper alloy heat conduction tube are connected to each other.

[0010] Preferably, filter cloth layers are evenly arranged inside the filter air duct member, enabling the filter air duct member to achieve good filter and dust protection.

[0011] Preferably, fixing screw holes are evenly arranged on the assembly substrate, facilitating the flexible assembly of electrical components on the assembly substrate provided with fixing screw holes through screws.

[0012] Preferably, limiting telescopic rods are evenly connected between the pressing plate and the insulation branch interface, enhancing the stability effect when the pressing plate moves.

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

[0014] (1). By installing the first copper alloy heat conduction tube, etc., the structure of the dense busbar optimizes its own structure. On the one hand, by evenly welding heat dissipation fins on both the housing and the second side cover plate, the heat conduction and dissipation performance of the outer walls of the housing and the second side cover plate is improved. On the other hand, users can assemble electrical components on the assembly substrate through screws.

Compared with the structure of simply arranging heat dissipation fins on the housing, it realizes the high-efficiency heat dissipation function for the electrical component structure, and the filter air duct member can also provide dust filtration protection for the heat conduction and dissipation structure;

[0015] (2). By providing an insulation branch interface, etc., the structure of the dense busbar optimizes its own performance. Users can pass the cables to be connected through the insulation branch interface inside the conductor copper bar, and make the conductor part of the cable closely adhere to the conductive contact block.
