Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a segmented busbar structure that is easy to maintain. Background Technology

[0002] In modern power transmission systems, busbar trunking is an important power transmission and distribution equipment widely used in various buildings, industrial plants, and large commercial facilities. With the continuous growth of electricity demand and the increasing complexity of electrical systems, higher requirements are being placed on the performance and reliability of busbar trunking.

[0003] Segmented busbar trunking has been widely used in practical engineering due to its advantages such as ease of installation and expansion. However, a prominent problem currently facing segmented busbar trunking during use is that the connections are prone to damage. This is mainly due to defects in the connection structure design of traditional segmented busbar trunking, which makes it difficult to effectively cope with vibration, external tension, and thermal expansion and contraction during long-term operation, leading to loosening, poor contact, or even separation at the connections.

[0004] While existing technologies can achieve busbar connection and power transmission to a certain extent, they have several shortcomings. On the one hand, the connection structure lacks stability and cannot provide reliable mechanical connections, making it difficult to guarantee the operational stability of the busbar under complex operating conditions. On the other hand, there is a significant lack of convenience in maintenance. When a fault occurs at a busbar connection, the maintenance process is often cumbersome and complex, requiring substantial time and manpower. For example, traditional busbar maintenance may require large-scale disassembly of the entire system, which not only prolongs maintenance time but also increases the difficulty and workload, severely impacting the continuity and stability of power supply. Therefore, those skilled in the art have provided a segmented busbar structure that facilitates maintenance, in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a segmented busbar structure that is convenient for maintenance, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A segmented busbar trunking structure that is easy to maintain includes a busbar trunking 1, a busbar trunking 2, a conductive core 1, and a conductive core 2. One end of the busbar trunking 1 is fixedly connected to a fixed frame, and one end of the fixed frame is fixedly connected to a locking part. One end of the busbar trunking 2 is fixedly connected to an insertion frame, wherein the insertion frame is inserted into the fixed frame, and a locking ring is slidably connected to the outer ring of the fixed frame. The locking ring can be moved onto the locking part, thereby locking the insertion frame tightly.

[0008] As a further embodiment of this utility model: threaded holes are provided on both the upper and lower sides of the fixing frame, and threaded holes are provided on both the upper and lower sides of the insertion frame.

[0009] As a further improvement of this utility model: fixing screws are provided on both the upper and lower sides of the fixing frame, wherein the fixing screws are threadedly connected to threaded hole one and threaded hole two.

[0010] As a further embodiment of this utility model: four conductive cores are fixedly connected inside the first busbar trough, and a conductive head is fixedly connected to one end of each conductive core. Four conductive cores are fixedly connected inside the second busbar trough.

[0011] As a further improvement of this utility model: each of the two conductive cores is fixedly connected to a conductive socket at one end, wherein the conductive head is inserted into the conductive socket, and a graphite pad is provided on the inner wall of the conductive socket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Multiple locking structure: The insertion frame is inserted into the fixed frame for initial positioning, and then the locking ring is moved to the locking part to achieve secondary locking. Finally, the fixing screw is passed through the threaded hole for further reinforcement. This multiple locking method greatly enhances the connection stability between busbar duct one and busbar duct two, effectively resists external force pulling, vibration and other situations, reduces the risk of loosening and separation at the connection, and ensures the stability of power transmission.

[0014] 2. Preventing relative displacement: The various connection structures work together to precisely limit the relative displacement between busbar trunking one and busbar trunking two, ensuring that conductive core one and conductive core two always maintain accurate docking and good electrical connection during long-term use.

[0015] 3. Quick disassembly and assembly: During maintenance, simply unscrew the fixing screws and move the locking ring in sequence to easily release the connection lock between busbar duct one and busbar duct two, separating the two. The operation steps are simple and clear, greatly shortening maintenance time, improving maintenance efficiency, and reducing the duration of power supply interruption caused by maintenance.

[0016] 4. Facilitates component maintenance: The segmented design allows for easy separation of busbar trunking 1 and busbar trunking 2 when maintenance is required, directly exposing the internal conductive cores, connecting components, etc. Maintenance personnel can accurately locate faulty components and directly inspect, replace, or maintain them without the need for large-scale disassembly of the entire system as required by traditional busbar trunking, significantly reducing maintenance difficulty and workload.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-4 In this embodiment of the utility model, a segmented busbar trunking structure that facilitates maintenance includes a first busbar trunking 1, a second busbar trunking 2, a first conductive core 101, and a second conductive core 201. A fixing frame 6 is fixedly connected to one end of the first busbar trunking 1, and a locking part 5 is fixedly connected to one end of the fixing frame 6. An insertion frame 7 is fixedly connected to one end of the second busbar trunking 2, wherein the insertion frame 7 is inserted into the fixing frame 6. A locking ring 4 is slidably connected to the outer ring of the fixing frame 6, wherein the locking ring 4 can move onto the locking part 5, thereby tightly locking the insertion frame 7. Threaded holes 601 are provided on both the upper and lower sides of the fixing frame 6. The insertion frame 7 has threaded holes 701 on both the top and bottom sides. The fixing frame 6 has fixing screws 3 on both the top and bottom sides. The fixing screws 3 are threaded into the threaded holes 601 and 701. Four conductive cores 101 are fixedly connected in the busbar trough 1. Each conductive core 101 has a conductive head 102 fixedly connected to one end. Four conductive cores 201 are fixedly connected in the busbar trough 2. Each conductive core 201 has a conductive socket 202 fixedly connected to one end. The conductive head 102 is inserted into the conductive socket 202. Graphite pads are provided on the inner wall of the conductive socket 202.

[0024] The working principle of this utility model is as follows: During installation, the insertion frame 7 of busbar trough 2 is first inserted into the fixing frame 6 of busbar trough 1. At the same time, the conductive head 102 in busbar trough 1 is inserted into the conductive socket 202 in busbar trough 2, realizing the initial connection between the two busbar troughs and laying the foundation for subsequent electrical connection. Then, the locking ring 4 is moved to the locking part 5. Utilizing the characteristics of the locking part 5, the locking part 5 tightly locks the insertion frame 7, further enhancing the connection stability between the two busbar troughs and preventing relative movement during use. Then, by screwing the fixing screw 3 into the corresponding threaded holes on the upper and lower sides of the fixing frame 6 and the insertion frame 7, the connection between the two busbar troughs is further reinforced mechanically, ensuring that the overall structure remains stable when subjected to external force or vibration. The conductive core in busbar trough 1 is connected to the conductive socket 202 at the end of the conductive core 101 in busbar trough 2 through the conductive head 102 at one end. The inner wall of the conductive socket 202... The graphite pad plays a crucial role. On one hand, its excellent conductivity enhances the conductivity between the conductive head 102 and the conductive socket 202, ensuring stable and efficient current transmission through the connection. On the other hand, its lubrication reduces friction between components during the insertion and removal of the conductive head 102 from the conductive socket 202, protecting both components and extending their lifespan. When maintenance is required, first, unscrew the fixing screws 3 from the threaded holes of the fixing frame 6 and the insertion frame 7 to release their reinforcement effect on the two busbars. Then, move the locking ring 4 from the locking part 5 onto the fixing frame 6 to release the locking state of the locking part 5 onto the insertion frame 7. At this point, the mechanical lock between the two busbars is released. After completing these steps, busbar 1 and busbar 2 can be separated, facilitating inspection, replacement, or maintenance of the conductive cores and connecting components inside the busbars.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
