Technical Field
[0001] This utility model relates to the field of busbar transition joints, specifically a transition joint between cast busbar trunking and dense busbar trunking. Background Technology
[0002] In power transmission systems, cast iron busbars and compact busbars are widely used in various electrical equipment connection scenarios. However, existing technologies for connecting cast iron busbars and compact busbars have many drawbacks.
[0003] In terms of connection operations, traditional connection methods are often cumbersome and require a lot of time and manpower. For example, common connection methods may require workers to manually perform complex positioning and fastening operations on each connecting component, making it difficult to achieve fast and efficient connections, which seriously affects the progress of project construction.
[0004] When there is a deviation in the connection between cast-in-place busbar trunking and dense busbar trunking, the existing technology lacks an effective fine-tuning mechanism. Once the connection has an angular deviation, it can only be solved by disassembling and adjusting the position of the busbar trunking, which is extremely troublesome and makes it difficult to guarantee the accuracy of the connection. This can easily lead to unstable connection and affect the reliability of power transmission.
[0005] Heat dissipation is also a major challenge for existing technologies. During the operation of busbar trunking, a large amount of heat is generated. Current heat dissipation structures for transition sections are relatively simple, generally relying solely on natural heat dissipation, which is inefficient. This not only easily causes equipment overheating, affecting normal operation and shortening equipment lifespan, but may also lead to safety hazards such as fires. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conversion section for cast busbar trunking and dense busbar trunking.
[0007] The technical solution adopted by this utility model to solve its technical problem is: a conversion joint for cast busbar and compact busbar, including a conversion joint shell, an adjusting knob, a fixing post and a main connecting piece. The knob is rotatably connected inside the conversion joint shell, and the fixing post is threaded inside the knob. Multiple main connecting pieces are slidably connected to the outer wall of the fixing post. Both ends of the main connecting pieces are rotatably connected to secondary connecting pieces. The secondary connecting pieces are provided with secondary connecting piece fixing components inside. A heat dissipation shell is attached to the outer wall of the conversion joint shell. Multiple heat dissipation fins are fixed to the outer wall of the heat dissipation shell. A connecting component is provided on the outer side of the heat dissipation shell. A protective sleeve is inserted into the side wall of the heat dissipation shell.
[0008] Furthermore, the auxiliary connecting piece fixing component includes a limiting rod, which is slidably connected in an arc-shaped groove on the outer wall of the adapter housing. One end of the limiting rod is provided with a thread, and the outer wall of the thread is threadedly connected to the limiting rod fixing component. The limiting rod is slidably connected to the auxiliary connecting piece.
[0009] Furthermore, the interior of the heat dissipation shell is hollow to form a cavity, and the cavity contains silicone oil. An oil filling port is provided on one side wall of the heat dissipation shell.
[0010] Furthermore, the connecting assembly includes a stud, which is fixed to one side wall of the heat dissipation housing. A support plate is slidably connected to the outer wall of the stud, and a nut is threaded to the top of the outer wall of the stud.
[0011] Furthermore, a strip groove is provided at the connection between the support plate and the stud, allowing the support plate to slide on the outer wall of the stud via the strip groove.
[0012] Furthermore, the end face of the heat dissipation shell is fixed with a protruding ridge, which is connected to the protective sleeve by insertion.
[0013] The beneficial effects of this utility model are:
[0014] Fine-tuning mechanism: When there is a deviation in the connection between the cast busbar and the dense busbar, the limit rod fixing part can be rotated to release the fixation of the limit rod. At this time, the auxiliary connecting piece can rotate on the main connecting piece to make fine-tuning of the angle. During the adjustment process, the limit rod slides in the arc-shaped groove of the adapter shell. After the adjustment is completed, it is fixed by the limit rod fixing part. This effectively solves the deviation problem in the connection process and enhances the accuracy and adaptability of the connection.
[0015] Excellent heat dissipation performance: The heat dissipation shell is attached to the outer wall of the adapter shell, and the hollow cavity inside contains silicone oil, which can significantly increase the heat dissipation effect. At the same time, multiple heat dissipation fins are fixed on the outer wall of the heat dissipation shell, which, together with the cool air, can further improve the heat dissipation efficiency, promptly conduct away the heat emitted by the adapter shell, ensure the stability and safety of the equipment during operation, and prevent failures caused by overheating.
[0016] Reliable connection protection function: The protective sleeve is inserted into the side wall of the heat dissipation shell. The protruding ridge at one end is connected to the protective sleeve, and the other end is connected to the cast busbar and the compact busbar. This can effectively protect the connection position between the auxiliary connecting piece and the cast busbar and the compact busbar, avoid damage to the connection part caused by external factors, and extend the service life of the equipment.

[0024] See Figures 1-5 This is a schematic diagram of the structure of this utility model. A conversion joint for casting busbar and compact busbar includes a conversion joint housing 1, an adjusting knob 2, a fixing post 3, and main connecting pieces 4. The knob 2 is rotatably connected inside the conversion joint housing 1. When the knob 2 rotates on the outer wall of the fixing post 3, it drives the outer wall of the conversion joint housing 1 to move inward. During the movement, the conversion joint housing 1 can drive multiple main connecting pieces 4 to retract inward, connecting the casting busbar and the compact busbar. The fixing post 3 is threadedly connected inside the knob 2, and multiple main connecting pieces 4 are slidably connected to the outer wall of the fixing post 3.
[0025] Both ends of the main connecting piece 4 are rotatably connected to the secondary connecting pieces 5. The secondary connecting pieces 5 can rotate at the ends of the main connecting pieces, allowing for fine-tuning of the connection when the casting busbar groove and the dense busbar groove are connected. The secondary connecting pieces 5 have internal secondary connecting piece fixing components, which are used to fix the secondary connecting pieces 5 after adjustment. The outer wall of the adapter shell 1 is fitted with a heat dissipation shell 8, which can conduct and dissipate the heat emitted by the adapter shell 1. Multiple heat dissipation fins 9 are fixed on the outer wall of the heat dissipation shell 8, which work with cold air to dissipate heat. A connecting component is provided on the outer side of the heat dissipation shell 8, which can fix the heat dissipation shell 8 to the outer wall of the adapter shell 1. A protective sleeve 13 is inserted into the side wall of the heat dissipation shell 8. A protruding rib is fixed on the end face of the heat dissipation shell 8, which is inserted and connected to the protective sleeve 13. The other end of the protective sleeve 13 is connected to the casting busbar groove and the dense busbar groove. The protective sleeve 13 is used to protect the connection position between the secondary connecting piece 5 and the casting busbar groove and the dense busbar groove.
[0026] The secondary connecting piece fixing component includes a limiting rod 6, which is slidably connected in an arc-shaped groove on the outer wall of the adapter housing 1. One end of the outer wall of the limiting rod 6 is provided with a thread, and the outer wall of the thread is threaded to a limiting rod fixing component 7. The limiting rod 6 is slidably connected to the secondary connecting piece 5. When the secondary connecting piece 5 swings at the end of the main connecting piece 4, it can drive the limiting rod 6 to slide in the arc-shaped groove. After the angle is adjusted, it is fixed by the limiting rod fixing component 7.
[0027] The interior of the heat sink 8 is hollow, forming a cavity. The cavity contains silicone oil, which enhances the heat dissipation effect of the heat sink 8. A filling port is provided on one side wall of the heat sink 8. When the filling port is removed from the heat sink 8, the silicone oil in the heat sink 8 can be discharged, and at the same time, silicone oil can be added to the heat sink 8 through the filling port.
[0028] The connecting assembly includes a stud 11, which is fixed to one side wall of the heat sink housing 8. The heat sink housing 8 is fastened to the outer wall of the adapter housing 1. During the fastening process, the stud 11 slides inward inside the groove of the support plate 1. After being tightly fitted, it is fixed by a nut 12. The outer wall of the stud 11 is slidably connected to the support plate 10. The top of the outer wall of the stud 11 is threaded with a nut 12. A groove is provided at the connection between the support plate 10 and the stud 11. The support plate 10 can slide on the outer wall of the stud 11 through the groove.
[0029] When using this utility model:
[0030] First, insert the connecting piece between the cast busbar trough and the dense busbar trough into the main connecting piece 4 and the auxiliary connecting piece 5. After insertion, rotate the adjusting knob 2. The adjusting knob 2 moves inward on the outer wall of the fixing column 3. During the movement, it drives the adapter shell 1, the main connecting piece 4, and the auxiliary connecting piece 5 to move inward. During the movement, they are connected and fixed. After fixing, the heat dissipation shell 8 is fastened to the outer wall of the adapter shell 1. During the fastening process, the stud 11 slides inward in the strip slot of the support plate 10. After fitting, it is fixed by the nut 12. After fixing, heat dissipation can be carried out. The heat emitted by the adapter shell 1 is conducted and dissipated through the heat dissipation shell 8 and the heat dissipation fins 9.
[0031] When a deviation occurs during the connection between the cast busbar and the dense busbar, the limiting rod fixing part 7 is rotated to cancel the fixing of the limiting rod 6. After the fixing is canceled, the auxiliary connecting piece 5 rotates on the main connecting piece 4 to make a fine adjustment of the angle. During the adjustment, the limiting rod 6 slides in the arc-shaped groove of the adapter shell 1. After the adjustment is completed, it is fixed by the limiting rod fixing part 7. After the fixing is completed, the connection work can be carried out.
