Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a fully insulated tubular busbar. Background Technology

[0002] Against the backdrop of the global energy structure accelerating its transformation towards cleaner and lower-carbon energy, and the continuous advancement of new power system construction in China, the safety, efficiency, and reliability of power transmission equipment have become core concerns for the industry. Fully insulated tubular busbars, as key equipment for achieving high-current transmission in power systems, are widely used in power plants, substations, new energy power plants, and large industrial enterprises, undertaking the important function of power distribution and transmission. With their full insulation, high current-carrying capacity, and corrosion resistance, they are gradually replacing traditional bare busbars and cables, becoming core equipment for solving power transmission challenges in high-voltage, high-current scenarios, and are of great significance for improving the operational stability of power systems and reducing transmission losses.

[0003] A search revealed Chinese patent publication number CN216355873U, which discloses a novel fully insulated tubular busbar trunking system. The system includes a housing and insulated conduits. Binding frames are located on both sides of the interior of the housing. A first fixing plate is located at the lower end of each binding frame, and a second fixing plate is located at the upper end of each binding frame. Binding grooves are located on both sides of the housing cover. This novel fully insulated tubular busbar trunking system, with its binding frames, first fixing plate, second fixing plate, and locking mechanism, facilitates the installation of the insulated conduits inside the housing and ensures their stability. It also facilitates disassembly and maintenance. The inclusion of binding posts, flexible springs, and sealing blocks ensures an absolute seal between the housing cover and the housing, preventing rainwater intrusion and corrosion of the insulated conduits, thus expanding its application scenarios.

[0004] The aforementioned patent specification mentions that "by setting up a binding frame, a first fixing plate, a second fixing plate, and a bayonet, it is easy to install the insulated conduit inside the housing and ensure its stability, and it is also convenient to disassemble and repair. By setting up a binding column, a flexible spring, and a sealing block, it is easy to maintain an absolute seal between the cover and the housing, preventing rainwater intrusion from corroding the insulated conduit and improving its application scenarios." The above content can maintain an absolute seal between the cover and the housing, prevent rainwater intrusion from corroding the insulated conduit, and improve its application scenarios. However, some fully insulated tubular busbar trunking has obvious defects in its conductor connection structure, resulting in uneven conductor contact. The plug-in structure may have insufficient guiding accuracy, causing the conductor axis to shift during docking, forming one-sided contact, reducing power transmission efficiency, and causing safety hazards such as accelerated aging of the insulation layer and conductor ablation. Therefore, a fully insulated tubular busbar trunking is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fully insulated tubular busbar trunking system, which aims to solve the problem of uneven conductor contact in some devices.

[0006] To achieve the above objectives, this utility model provides a fully insulated tubular busbar trunking, including a connecting plate. A housing is fixedly connected to the outside of the connecting plate. Heat dissipation fins are fixedly connected to both sides of the outer surface of the housing. A fixing mechanism is provided outside the housing. A socket mechanism is provided outside the housing. A conductor is fixedly connected to the outside of the housing. A connecting mechanism is provided outside the connecting plate. The connecting mechanism includes a telescopic rod, which is fixedly connected to the outside of the connecting plate. A transmission plate is fixedly connected to the driving end of the telescopic rod. A transmission assembly is provided inside the transmission plate. A fixing plate is fixedly connected to the outside of the transmission assembly. An adjusting plate is fixedly connected to the outside of the transmission assembly.

[0007] The fixing mechanism includes a cylinder, which is fixedly connected to the outside of the housing, and a sliding bar is fixedly connected to the driving end of the cylinder.

[0008] The transmission assembly includes multiple sliding columns, the outer side of which is formed inside the transmission plate, and the outer side of the sliding column is slidably connected to a limit groove.

[0009] The limiting groove is fixedly connected to the outside of the adjusting plate, the adjusting plate is fixedly connected to the inside of the adjusting plate, and the two ends of the connecting plate are fixedly connected to the fixing plates.

[0010] The fixing plate is fixedly connected to the outside of the connecting plate, and the adjusting plate is slidably connected to the outside of the conductor.

[0011] The outer shell is fixedly connected to a limiting strip, the outer sliding strip is slidably connected to the outside of the limiting strip, and the outer sliding strip is rotatably connected to a rotating connecting rod.

[0012] The rotating connecting rod is rotatably connected to a rotating connecting plate at its other end, and a limiting post is fixedly connected to the outside of the outer shell. The rotating connecting plate is rotatably connected to the outside of the limiting post.

[0013] The insertion mechanism includes a second limiting strip, which is fixedly connected to the outside of the outer shell. A sliding baffle is slidably connected inside the second limiting strip, and the sliding baffle is slidably connected to the outside of the outer shell.

[0014] This utility model discloses a fully insulated tubular busbar trunking system. A telescopic rod drives a transmission plate, which in turn moves a sliding column within a limiting groove. The guiding effect of the limiting groove allows the adjusting plate to move stably along a preset trajectory, ensuring a perfect fit with the outer wall of the tubular conductor and achieving a tight, circumferential clamping. A fixing plate provides a stable fulcrum for the entire transmission process, ensuring a uniform distribution of the clamping force on the conductor. This effectively avoids conductor damage caused by excessive localized force, improving the busbar trunking's conductivity and operational safety. Furthermore, this structural design can adapt to tubular conductors of different specifications, enhancing the busbar trunking's versatility and installation flexibility. It is also easy to operate, allowing for quick conductor clamping and fixation, thus improving installation and maintenance efficiency.

[0015] This utility model discloses a fully insulated tubular busbar trunking system. The power output driven by a cylinder is stable and controllable. Combined with the groove-shaped constraint of the limiting strip and the hinged structure of the rotating connecting rod and rotating connecting plate, linear motion is efficiently converted into a flipping action. This allows for precise control of the opening and closing angle of the rotating connecting plate, achieving a tight lock with the support frame. It also provides convenient operating space for the installation, maintenance, or replacement of external docking boxes, improving the safety, stability, and maintenance efficiency of the busbar trunking's connection to external equipment.

[0022] The first embodiment of this application is as follows:

[0023] Please see Figures 1 to 3 A fully insulated tubular busbar trunking includes a connecting plate 1, which is used to connect two sections of the busbar trunking during splicing to ensure the stability of the overall structure. A shell 4 is fixedly connected to the outside of the connecting plate 1. The shell 4 is made of high-strength insulating material for physical protection. Heat dissipation fins 2 are fixedly connected to both sides of the shell 4. The heat dissipation fins 2 are made of high thermal conductivity material, which increases the contact area with air, accelerating the dissipation of heat from the shell 4 to the external environment and effectively reducing the operating temperature of the busbar trunking. A fixing mechanism 6 is provided on the outside of the shell 4 to quickly and securely install the busbar trunking's connecting box. A socket mechanism 7 is provided on the outside of the shell 4, serving as the connection interface between the busbar trunking and external equipment or branch lines. A conductor 3 is fixedly connected to the outside of the shell 4. The conductor 3 is typically a tubular structure made of high-purity copper or aluminum alloy and is the core carrier for power transmission. A connecting mechanism 5 is provided on the outside of the connecting plate 1 to achieve precise docking and tight connection between the two sections of the busbar trunking conductor 3, ensuring the continuity and stability of current transmission.

[0024] The connecting mechanism 5 includes a telescopic rod 52, which serves as the power actuator of the connecting mechanism 5. The telescopic rod 52 drives the transmission plate 51 to move through its telescopic movement, thereby achieving the clamping or loosening action of the adjusting plate 55 on the conductor 3. The telescopic rod 52 is externally fixedly connected to the outside of the connecting plate 1. The driving end of the telescopic rod 52 is fixedly connected to the transmission plate 51. The transmission plate 51 plays the role of force transmission and distribution, transmitting the power of the telescopic rod 52 to the transmission assembly 53. The transmission assembly 53 is provided inside the transmission plate 51. The transmission assembly 53 is used to convert the linear motion of the transmission plate 51 into the circumferential motion of the adjusting plate 55, thereby achieving the clamping of the conductor 3. The transmission assembly 53 is externally fixedly connected to a fixed plate 54, which serves as the fixed fulcrum and installation reference of the transmission assembly 53, providing stable support for the connecting column 533 and the adjusting plate 55, ensuring that the position of each component does not shift during the transmission process. The transmission assembly 53 is externally fixedly connected to an adjusting plate 55, which achieves the circumferential clamping or loosening of the conductor 3 through its own movement.

[0025] The transmission assembly 53 includes multiple sliding columns 532. The sliding columns 532 can slide within the holes of the transmission plate 51 and cooperate with the limiting groove 531 to transmit the movement of the transmission plate 51 to the adjusting plate 55. The outer side of the sliding column 532 is opened inside the transmission plate 51, and the outer side of the sliding column 532 is slidably connected to the limiting groove 531. The limiting groove 531 is opened on the adjusting plate 55 to provide a precise guide trajectory for the movement of the sliding column 532. The outer side of the limiting groove 531 is fixedly connected to the outer side of the adjusting plate 55. The inner side of the adjusting plate 55 is fixedly connected to a connecting column 533. The connecting column 533 connects and fixes the adjusting plates 55 and the fixing plate 54 on both sides, making the movement of the adjusting plate 55 more stable. The outer ends of the connecting column 533 are fixedly connected to the fixing plate 54. The outer side of the fixing plate 54 is fixedly connected to the outer side of the connecting plate 1. The outer side of the adjusting plate 55 is slidably connected to the outer side of the conductor 3.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing mechanism 6 includes a cylinder 61, which is externally fixedly connected to the outside of the housing 4. A sliding bar 62 is fixedly connected to the driving end of the cylinder 61. Driven by the cylinder 61, the sliding bar 62 slides along a limiting bar 63, transmitting the power of the cylinder 61 to the rotating connecting rod 64. The limiting bar 63 is fixedly connected to the outside of the housing 4, guiding and limiting the movement of the sliding bar 62, ensuring that the sliding bar 62 can only move along a preset straight line, preventing it from deviating or jamming during movement. The outside of the sliding bar 62 is slidably connected to the outside of the limiting bar 63. An external rotating connection is provided with a rotating link 64, which acts as a force transmission medium, converting the linear motion of the sliding bar 62 into the rotational motion of the rotating plate 65. The other end of the external rotating link 64 is rotatably connected to the rotating plate 65. The rotating plate 65 locks or separates from the mounting bracket through its own rotation. A limit post 66 is fixedly connected to the outside of the outer shell 4. The limit post 66 serves as the rotation fulcrum of the rotating plate 65 and is fixed to the outer shell 4 to ensure that the rotating plate 65 rotates around a fixed axis, thus ensuring the stability and accuracy of its opening and closing action. The external rotating connection of the rotating plate 65 is rotatably connected to the outside of the limit post 66.

[0027] The insertion mechanism 7 includes a second limiting strip 71, which provides a guide track for the sliding baffle 72 to slide, ensuring that the sliding baffle 72 can only move smoothly along the surface of the outer shell 4. The second limiting strip 71 is fixedly connected to the outside of the outer shell 4, and the sliding baffle 72 is slidably connected inside the second limiting strip 71. The sliding baffle 72 can slide along the second limiting strip 71 and the surface of the outer shell 4 to realize the opening and closing of the insertion. When closed, it can fit tightly against the outer shell 4, playing a sealing and protective role. The sliding baffle 72 is slidably connected to the outside of the outer shell 4.

[0028] In this specific embodiment, the telescopic rod 52 supported by the connecting plate 1 drives the transmission plate 51 to move axially. At this time, the sliding column 532 inside the transmission plate 51 slides along a preset trajectory in the limiting groove 531. Through the guiding effect of the limiting groove 531, the connecting column 533 and the adjusting plate 55 move synchronously. The fixing plate 54 is on the connecting plate 1, providing a stable fulcrum for the transmission assembly 53. As the adjusting plate 55 moves, its inner side gradually fits against the outer wall of the conductor 3, which can completely match the tubular conductor 3, and finally achieves a circumferential clamping of the conductor 3.

[0029] After conductor 3 is connected, the cylinder 61 receives a signal and outputs power to push the sliding bar 62 to slide horizontally along the track of the limiting bar 63. The groove structure of the limiting bar 63 strictly limits the offset of the sliding bar 62. As the sliding bar 62 moves, the rotating connecting rod 64 rotates around the limiting post 66. The other end of the rotating connecting rod 64 is hinged to the rotating connecting plate 65, which will drive the rotating connecting plate 65 to rotate synchronously, releasing the locking and fixing of the external docking box with the bracket.

[0030] After the busbar trunking is put into operation, the outer shell 4 and the heat dissipation fins 2 continue to perform heat dissipation and insulation protection functions to ensure system stability. Normally, the sliding baffle 72 is tightly attached to the surface of the outer shell 4 along the track of the second limit strip 71 to form a sealed structure to prevent rainwater and debris from entering the interior. The inner side of the second limit strip 71 is provided with a rubber sealing strip, which cooperates with the edge of the sliding baffle 72 to restore the sealing of the outer shell 4 and facilitate the installation of the external box.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
