Technical Field

[0001] This utility model belongs to the field of power engineering technology, specifically relating to a through-core connected fluidized busbar trunking. Background Technology

The copper busbars are wrapped with insulating material, and after the copper busbars of each phase are pressed together, there are no gaps or intervals between the copper busbars. The insulation layer may get damp, and the water inside cannot evaporate (there are gaps between the insulation layers), which can cause short circuits. Therefore, it is necessary to design a through-core connected fluidized busbar trunking to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a through-hole connected fluidized busbar trough, including a housing 1 and a fluidized busbar 2 installed inside the housing 1. The fluidized busbar 2 and the inner side of the housing 1 are provided with through holes 8. The inner side of the through holes 8 is provided with fixing bolts 3. One end of the fixing bolts 3 is provided with fixing nuts 7. The housing 1 and the fluidized busbar 2 are fixedly connected by fixing bolts 3 and fixing nuts 7.

[0019] As can be seen from the above description, this utility model has the following beneficial effects: The material of this utility model is a fast-curing insulating powder, and there is no gap between the insulating layer and the conductor busbar. Its heat dissipation performance, moisture resistance, and insulation reliability are all excellent; the protection level can be upgraded, from IP66 to IP68; the temperature rise of the busbar conductor and shell is reduced compared to the original busbar temperature; the vulcanized busbar conductor gauge of this utility model is smaller than the relative current rating, saving costs.

[0020] Further reading is available. Figures 1 to 3The outer casing 1 is clamped and installed on both sides of the fluidizing busbar 2. The fluidizing busbar 2 is stacked and installed inside the outer casing 1 to ensure greater stability during installation. An insulating sleeve 5 is installed in the through hole 8 on the inner side of the fluidizing busbar 2. The fixing bolt 3 passes through the insulating sleeve 5 and is connected to the fixing nut 7. During use, the insulating sleeve 5 enhances the insulation capacity of the fixing bolt 3, thereby facilitating the fixation of the fluidizing busbar 2. An insulating spacer 6 is provided on the outer side of the insulating sleeve 5. The fluidizing busbar 2 is positioned and fitted onto the insulating sleeve 5 through the insulating spacer 6, which facilitates the positioning and installation of the fluidizing busbar 2. Insulating washers 4 are provided at both ends of the fixing bolt 3. The insulating washers 4 press against the outer surface of the outer casing 1 to strengthen the connection between the fixing bolt 3 and the outer casing 1. An insulating layer is provided on the surface of the fluidizing busbar 2, and the conductor copper busbar of the fluidizing busbar 2 is fluidized and insulated. The two ends of the conductor are tin-plated.

[0021] The connectors at both ends of the busbar trunking of this utility model adopt waterproof pressure plates, and sealing gaskets are added to both sides of the pressure plates to make the protection performance more reliable. The connectors are made using a casting process.

[0022] By adopting the above technical solution, under the premise of ensuring that the fluidization process meets the electrical performance requirements, the use of through bolts can better ensure the overall compactness of the busbar trunking and improve the heat dissipation performance of the busbar trunking; the use of through bolt structure ensures the protective performance of the outer shell; and the through bolts are insulated, which can better ensure the electrical performance of the busbar trunking.

[0023] The conductor insulation layer is produced using a fluidized bed process.

[0024] The conductor busbar is heated in an oven, then immersed in a fluidized bed via a transmission device and adhered to the copper busbar. After melting and leveling, it solidifies to form an insulating protective coating, replacing the current bushing process. This process allows the coating to adhere more evenly to the copper busbar surface, thus improving the quality of the surface powder coating. Successful tests were conducted on coating thickness, bending, adhesion, impact strength, flame retardancy, insulation heat resistance, and cross-sectional porosity.

[0025] The working principle and usage process of this utility model are as follows: When in use, the fluidizing busbar 2 is installed inside the outer shell 1, and the insulating sleeve 5 is installed in the through hole 8 on the fluidizing busbar 2. The fluidizing busbars 2 are separated by the insulating spacer 6. Then, the fixing bolt 3 is passed through the outer shell 1 and the insulating sleeve 5, and the insulating gaskets 4 at both ends of the fixing bolt 3 are attached to the outer surface of the outer shell 1. The fixing nut 7 is screwed onto one end of the fixing bolt 3 for fixing.
