Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a plug-in busbar structure. Background Technology

[0002] In power transmission systems, busbar trunking, as a core conductive component, is widely used in high-rise buildings, industrial plants, and other locations. Traditionally, when connecting two sections of a busbar trunking, direct bolting or welding is often used, which presents problems such as inconvenient installation and disassembly, and poor connection stability. In terms of heat dissipation, it relies heavily on natural convection, which is insufficient to meet the heat dissipation requirements under high loads, leading to decreased conductivity and even safety hazards due to excessively high temperatures.

[0006] Preferably, a heat-conducting plate is fixedly connected to the upper surface of the base plate, and threaded holes are opened on the lower surfaces of both ends of the base plate.

A through hole is opened on the lower surface of the base plate, and the heat-conducting pipe in the heat dissipation structure on the lower surface of the base plate passes through the through hole on the lower surface of the base plate and is fixedly connected to the outer surface of the heat-conducting plate.

[0007] Preferably, the plug-in piece is inserted into the interior of one opposite end of the two busbar trunking sections.

[0008] Preferably, nuts are threaded to both ends of the screw.

[0010] Compared with related technologies, the plug-in busbar structure provided by this utility model has the following advantages:

[0011] 1. The system is equipped with a base plate, a connecting structure, and a top plate. The base plate provides bottom support, while the top plate covers and protects the internal conductive components. Both are tightly connected to the busbar trunking body by bolts, which enhances the overall structural strength and prevents external impacts and foreign object intrusion, ensuring electrical safety. The combination of plug-in plates and screw nuts enables quick plugging and fastening of the two busbar trunking sections. Compared with traditional bolt or welding methods, installation and disassembly are more convenient, while ensuring the mechanical strength and electrical conductivity of the connection parts.

[0012] 2. By setting up a heat dissipation structure, consisting of heat-conducting plates, heat-conducting pipes, and heat dissipation fins on the bottom and top plates, a two-way heat dissipation channel is formed. The convection conduction of the heat-conducting oil and the large-area heat dissipation of the heat dissipation fins can quickly dissipate the heat generated by the busbar trunking body during operation, effectively reducing the working temperature and improving the stability and service life of the busbar trunking body.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 and Figure 3The system includes: a busbar trunking body 1, a base plate 2, a connecting structure 3, a top plate 4, and a heat dissipation structure 5. The busbar trunking body 1 has two sections. The core conductive component of the busbar trunking body 1 is used to transmit electrical energy. A base plate 2 is provided on the lower surface of the two busbar trunking body sections opposite each other. The base plate 2 is fixed to the lower surface of the two busbar trunking body sections opposite each other, providing bottom support and enhancing the stability of the overall structure. A top plate 4 is provided above the base plate 2. A connecting structure 3 is provided between the base plate 2 and the top plate 4. The connecting structure 3 includes a fixing plate 6, a plug-in piece 7, and a screw 8. Two fixing plates 6 are provided, and the two fixing plates are used to fix... Through holes are provided on the side surfaces of the plate 6. A plug-in piece 7 is provided between the two fixing plates 6. Through holes are provided on the side surfaces of the plug-in piece 7. Screws 8 are provided inside the through holes on the side surfaces of the two fixing plates 6 and the plug-in piece 7. Heat dissipation structures 5 are provided on the lower surface of the bottom plate 2 and the upper surface of the top plate 4. The heat dissipation structure 5 includes heat pipes 9 and heat dissipation fins 10. Heat dissipation fins 10 are fixedly connected to the outer surface of the heat pipes 9. The heat pipes 9 are filled with heat-conducting oil. By increasing the heat dissipation area, the heat dissipation fins 10 accelerate the dissipation of heat to the surrounding air, reduce the operating temperature of the busbar trunking body 1, and ensure that it operates within a safe temperature range.

[0019] In the specific implementation process, threaded holes are opened on the upper and lower surfaces of the two busbar trunking bodies 1 at opposite ends.

[0020] A heat-conducting plate 11 is fixedly connected to the upper surface of the base plate 2. When the temperature at the connection point of the two busbar trunking bodies 1 rises, heat radiation is generated. Since the temperature will be transferred from high temperature to low temperature, the heat-conducting plate 11 will absorb heat. Threaded holes are opened on the lower surfaces of both ends of the base plate 2. The threaded holes on the lower surfaces of both ends of the base plate 2 correspond to the threaded holes on the lower surfaces of the two busbar trunking bodies 1 at opposite ends. Bolts 12 are threadedly connected to the threaded holes on the lower surfaces of both ends of the base plate 2 and the threaded holes on the lower surfaces of the two busbar trunking bodies 1 at opposite ends. A through hole is opened on the lower surface of the base plate 2. The heat-conducting pipe 9 in the heat dissipation structure 5 on the lower surface of the base plate 2 passes through the through hole on the lower surface of the base plate 2 and is fixedly connected to the outer surface of the heat-conducting plate 11. The heat-conducting pipe 9 conducts heat quickly through the convection of the internal heat-conducting oil, transferring the heat of the busbar trunking body 1 through the heat-conducting plate 11 to the heat dissipation fins 10.

[0021] The plug-in piece 7 is inserted into the interior of one opposite end of the two busbar trunking bodies 1. The plug-in piece 7 is directly inserted into the interior of one opposite end of the two busbar trunking bodies 1 as a conductive connector to realize electrical conduction between the two busbar trunking bodies 1.

[0022] The screw 8 has nuts 13 threadedly connected to both ends. The screw 8 passes through the through holes of the fixing plate 6 and the plug-in piece 7. The nuts 13 lock the two ends together, thus fixing the fixing plate 6, the plug-in piece 7 and the busbar trunking body 1 to one side, ensuring the mechanical strength of the connection structure 3 and the electrical conductivity reliability of the busbar trunking body 1.

[0023] Among them, a heat-conducting plate 11 is fixedly connected to the lower surface of the top plate 4, and threaded holes are opened on the upper surfaces of both ends of the top plate 4. The threaded holes on the upper surfaces of both ends of the top plate 4 correspond to the threaded holes on the upper surfaces of the two busbar trunk bodies 1. Bolts 12 are threadedly connected to the threaded holes on the upper surfaces of both ends of the top plate 4 and the threaded holes on the upper surfaces of the two busbar trunk bodies 1. A through hole is opened on the upper surface of the top plate 4, and the heat-conducting pipe 9 in the heat dissipation structure 5 on the upper surface of the top plate 4 passes through the through hole on the upper surface of the top plate 4 and is fixedly connected to the outer surface of the heat-conducting plate 11.

[0024] The working principle of this utility model is as follows: The plug-in piece 7 is inserted into the interior of one opposite end of the two busbar trunking bodies 1. Two fixing plates 6 are aligned with the plug-in piece 7 through through holes. After the screw 8 passes through the through hole, it is locked with a nut 13, thus securing the plug-in piece 7, fixing plates 6, and busbar trunking bodies 1. This achieves a stable electrical connection between the two busbar trunking bodies 1, ensuring smooth power transmission. The threaded holes on the upper and lower surfaces of the two busbar trunking bodies 1 at opposite ends are fixed to the bottom plate 2 and top plate 4 respectively by bolts 12, forming a stable mechanical frame. The power generated during the operation of the busbar trunking bodies 1... Heat is transferred to the heat-conducting plates 11 of the bottom plate 2 and the top plate 4 through thermal radiation. After the heat-conducting plates 11 absorb the heat, they transfer the heat to the heat-conducting oil inside the heat-conducting pipe 9 through direct contact with the heat-conducting pipe 9. The heat-conducting oil convects inside the pipe and quickly conducts the heat to the heat dissipation fins 10. The heat dissipation fins 10 dissipate the heat to the surrounding environment by increasing the contact area with the air, forming a complete heat dissipation path of "bus trunking body 1 → heat-conducting plate 11 → heat-conducting pipe 9 → heat dissipation fins 10 → air", which continuously reduces the temperature of the bus trunking body 1 and ensures its safe and stable operation.

[0025] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
