Description

Technical Field

[0001] This utility model relates to the field of porcelain wall bushing technology, specifically to a porcelain wall bushing. Background Technology

[0002] Wall bushings are also called wall pipes, waterproof sleeves, or wall embedded pipes. Waterproof sleeves are divided into rigid waterproof sleeves and flexible waterproof sleeves. In the power industry, those used for conducting electricity are called AC wall bushings. Based on the material, they can be divided into dry capacitor type AC wall bushings and porcelain insulated AC wall bushings, which are abbreviated as silicone rubber bushings and porcelain bushings, respectively.

[0003] Existing porcelain wall bushings utilize the insulating properties of porcelain components to isolate conductive parts from the wall, thereby enabling electrical equipment to pass through the wall. While this method can provide protective insulation for cables, during wall installation, the bushing inside the wall needs to be completely fixed to ensure stability. When cables and other components are working inside the bushing, the heat generated by the electrode cores accumulates inside the wall, and the dissipation rate is limited by the wall. This heat accumulation can easily lead to thermal short circuits in the electrode cores inside the wall, affecting the lifespan of the device. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1-3 As shown, an electrical porcelain through-wall bushing in this embodiment includes an insulating wall pipe 3. Heat dissipation fins 2 are arranged around the outer wall of the insulating wall pipe 3. One end of the insulating wall pipe 3 is connected to a flange 1, and the other end is provided with a flange 2 7. Ventilation mesh plates 4 are installed around the outer walls of both flange 1 and flange 2 7. The design of the insulating wall pipe 3, flange 1, and flange 2 7 facilitates the fixed installation of the insulating wall pipe 3 in the middle of the wall. Combined with the design of the heat dissipation fins 2, direct contact between the side wall of the insulating wall pipe 3 and the wall can be effectively avoided. After the heat inside the insulating wall tube 3 is discharged, the heat can flow between the heat dissipation fins 2. With the design of the ventilation mesh plate 4 on flange 1 and flange 2 7, the heat between the heat dissipation fins 2 can be effectively discharged. Both flange 1 and flange 2 7 have a sealing groove 6 in the middle. The middle of the insulating wall tube 3 is connected to two end plates 11 through two sealing plates 5. An electric porcelain tube 8 is arranged on one side of the end plate 11. A polyurethane elastomer 16 is provided on the outer wall of the end plate 11. The outer side of the polyurethane elastomer 16 is connected to the elastic sealing gasket 10 through flexible silicone rubber 15.

[0018] like Figures 1-3 As shown, in this embodiment, two porcelain tubes 8 are connected to an electrode core 12 in the middle. Two mounting plates 17 are symmetrically arranged at both ends of the electrode core 12. One end of the mounting plate 17 is connected to the terminal block 14 through a dust cover 13. A ceramic outer cylinder 9 is connected around the outer wall of the porcelain tube 8. There are no fewer than two ceramic outer cylinders 9. The design of the porcelain tube 8 and the ceramic outer cylinder 9 effectively achieves insulation isolation between the conductive part and the wall.

[0019] like Figures 1-3 As shown, in this embodiment, the electrode core 12 passes through the ceramic tube 8 and the insulating wall tube 3. The electrode core 12 is connected to the mounting plate 17 through a slot. The design of the electrode core 12 facilitates the insulation and conduction of current.

[0020] like Figures 1-3 As shown, in this embodiment, the terminal block 14 is electrically connected to the electrode core 12, and the ceramic outer cylinder 9 is plugged into the electric porcelain tube 8. The design of the terminal block 14 facilitates electrical connection with electrical equipment and achieves insulated wiring for electrical equipment.

[0021] like Figures 1-3As shown, in this embodiment, flange 1 and flange 2 are both welded to the insulating wall pipe 3, and the ventilation mesh plate 4 is connected to flange 1 and flange 2 7 by a slot. The design of flange 1 and flange 2 7 facilitates the fixed installation of the insulating wall pipe 3 on both sides of the wall.

[0022] like Figures 1-3 As shown, in this embodiment, the heat dissipation fins 2 are inserted into the insulating wall tube 3, and the end plate 11 is connected to the sealing groove 6. The design of the heat dissipation fins 2 can conduct heat out of the insulating wall tube 3. With its protruding structure, it can effectively avoid direct contact between the insulating wall tube 3 and the wall. When the heat passes through the ventilation mesh plate 4, it realizes the circulation and exchange of air, effectively avoiding the problem of heat accumulation in the wall causing short circuit.

[0023] like Figures 1-3 As shown, in this embodiment, the sealing disc 5 is pressed together with the porcelain tube 8, and the polyurethane elastomer 16 is bonded to the end plate 11. The design of the sealing disc 5 facilitates the connection and fixation of the porcelain tube 8 and the insulating wall tube 3, so that both ends of the insulating wall tube 3 can be insulated from electrical equipment.

[0024] like Figures 1-3 As shown, in this embodiment, the flexible silicone rubber 15, the polyurethane elastomer 16, and the elastic sealing gasket 10 are all bonded together. The porcelain tube 8 is connected to the flange 1 and the flange 7 by a slot. The design of the flexible silicone rubber 15, the polyurethane elastomer 16, and the elastic sealing gasket 10 can achieve a sealed connection between the end plate 11 and the sealing groove 6. At the same time, when the external temperature changes, the three can absorb and buffer the stress generated by thermal expansion, which can effectively prevent the end of the porcelain tube 8 from being damaged by stress when connected to the insulating wall tube 3.

[0025] The specific implementation process of this embodiment is as follows: When using the device, the insulating wall pipe 3 needs to be installed inside the wall, and flange 1 and flange 7 are fixed to both ends of the wall respectively. With the design of the sealing plate 5, the insulating wall pipe 3 is fixed to the sealing plate 5. The design of the end plate 11 achieves the sealing of the two sealing grooves 6 of flange 1 and flange 7. With the design of the polyurethane elastomer 16 and flexible silicone rubber 15, the two materials can effectively absorb and buffer the stress generated by thermal expansion of the end plate 11. With the elastic sealing gasket 10 sealing the sealing groove 6, the stress damage to the end plate 11 caused by thermal expansion can be effectively avoided, thus effectively ensuring the flange... The sealing of the connection between flange 1 and flange 2 and the porcelain tube 8 ensures that, after installation, electrical equipment can be connected via terminal block 14, effectively protecting and insulating the cables. Combined with the design of the heat dissipation fins 2, direct contact between the sidewall of the insulating wall tube 3 and the wall is effectively avoided. After the heat dissipation fins 2 dissipate heat from the insulating wall tube 3, heat can circulate between the heat dissipation fins 2. Combined with the design of the ventilation mesh plate 4 on flange 1 and flange 2, heat can be effectively dissipated between the heat dissipation fins 2. Simultaneously, the insulating properties of the porcelain components isolate the conductive parts from the wall, effectively achieving through-wall connection of electrical equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
