An integrated high-current busbar bushing

Abstract

This utility model discloses an integrated high-current busbar bushing. It relates to the field of busbar bushing technology and employs a design including a first partition, a second partition, and a fixing device. Each of the first and second partitions has an inner sleeve at its other end, and a groove is formed at the center of one end of the first partition. This utility model allows the guide plate to slide within an L-shaped guide groove to a suitable position by pulling it. Then, by releasing the guide plate, a limiting rod is inserted into a limiting hole on the surface of the positioning plate under the action of a spring, thereby fixing the first and second partitions. This solves the problem that existing busbar bushings typically rely solely on the engagement of the busbar and its hole for fixing during installation. However, due to the small gap between the busbar and the hole, and the limited position during busbar installation, inserting the busbar into the hole is difficult, adjusting the hole during installation is even more challenging, and disassembly is also complex.

Description

Technical Field

[0001] This utility model relates to the field of busbar bushing technology, specifically to an integrated high-current busbar bushing. Background Technology

[0002] Busbar bushings are used for insulation and transition in high-voltage switchgear. They are typically made of epoxy resin and have awnings on the outside. Inside the bushing, there is a partition with busbar holes. During installation, the busbar passes through the busbar holes, which are rectangular in shape and their size is adapted to the busbar being inserted. The gap between the busbar and the hole is usually about 3 mm to ensure the busbar is positioned correctly. However, existing busbar bushings are usually fixed by simply engaging the busbar and the hole during installation. Due to the small gap between the busbar and the hole, and the limited space during installation, inserting the busbar through the hole is difficult. Adjusting the hole during installation is even more challenging, and disassembly is also quite complicated. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an integrated high-current busbar bushing, which solves the problems raised in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An integrated high-current busbar bushing includes a first partition, a second partition, and a fixing device. Each of the first and second partitions has an inner sleeve at its other end. A groove is formed at the center of one end of the first partition. A symmetrical limiting frame is fixedly installed at the other end of the second partition. Symmetrical sliding rods are fixedly installed inside the limiting frame, and sliders are slidably connected to the sliding rods. A movable plate is provided at one end of the slider, and a limiting rod is provided at the other end of the movable plate. The limiting rod is movably connected to the limiting frame. A positioning plate is fixedly installed at the other end of the second partition, outside the limiting frame. A positioning hole is formed at one end of the first partition to cooperate with the positioning plate. A limiting hole is formed on the surface of the positioning plate to cooperate with the limiting rod. A spring is provided between the movable plate and the limiting frame, around the limiting rod. A guide plate is fixedly installed on the front of the movable plate. A symmetrical L-shaped guide groove is formed on the front of the first partition, and the guide plate and the L-shaped guide groove are slidably connected. Fixing devices are provided at both the top and bottom ends of the first partition.

[0005] Preferably, the outer wall of the inner sleeve is provided with an insulating outer sleeve, and the outer surface of the insulating outer sleeve is uniformly provided with a plurality of creepage skirts.

[0006] Preferably, the other end of the inner sleeve is provided with a terminal block, and the surface of the terminal block is provided with symmetrical wire-locking grooves.

[0007] Preferably, the fixing device includes symmetrical support plates, the support plates are threadedly connected to threaded rods, one end of the threaded rods is provided with a handwheel, and the other end of the threaded rods is threadedly connected to a nut.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are: The integrated high-current busbar bushing provided by this utility model allows for quick positioning and guidance between the first and second partitions by using a positioning hole at one end of the first partition and a positioning plate at the other end of the second partition. The guide plate is then pulled to slide within the L-shaped guide groove to a suitable position. Releasing the guide plate causes a spring to insert a limiting rod into a limiting hole on the surface of the positioning plate, thus fixing the first and second partitions. This solves the problem that existing busbar bushings typically rely solely on the engagement of the busbar and its hole for fixation during installation. However, due to the small gap between the busbar and its hole, and the limited position during installation, inserting the busbar into the hole is difficult, adjusting the hole during installation is even more challenging, and disassembly is also complex. Furthermore, by providing symmetrical sliding rods within the limiting frame and fixing sliders at both ends of the movable plate, the stability of the limiting rod during movement is improved by allowing the sliders to slide on the sliding rods. This utility model provides an insulating outer sleeve on the outer wall of the inner sleeve to isolate the inner sleeve and prevent leakage. Furthermore, a number of creepage skirts are evenly arranged on the outer surface of the insulating outer sleeve to prevent creepage. This utility model features a fixing device. By rotating a handwheel, the threaded rod is rotated to a suitable position, thereby locking the threaded rod onto the support plate. Then, the nut is tightened, further improving the fixation of the first and second partitions. Attached Figure Description

[0013] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0014] According to an embodiment of the present invention, an integrated high-current busbar bushing is provided.

[0015] Example 1: As shown in the attached diagram of the instruction manual. Figure 1 As shown, an integrated high-current busbar bushing includes a first partition 1, a second partition 2, and a fixing device 20. Each of the first and second partitions 1 and 2 has an inner sleeve 3 at its other end. A groove 8 is formed at the center of one end of the first partition 1. A symmetrical limiting frame 9 is fixedly installed at the other end of the second partition 2. A symmetrical sliding rod 10 is fixedly installed inside the limiting frame 9. A slider 11 is slidably connected to the sliding rod 10. A movable plate 12 is provided at one end of the slider 11, and a limiting rod 13 is provided at the other end of the movable plate 12. The limiting rod 13 is movably connected to the limiting frame 9. The second partition 2... A positioning plate 14 is fixedly installed at the other end of the first partition 1 and on the outside of the limiting frame 9. A positioning hole 16 is provided at one end of the first partition 1 to cooperate with the positioning plate 14. A limiting hole 15 is provided on the surface of the positioning plate 14 to cooperate with the limiting rod 13. A spring 18 is provided between the movable plate 12 and the limiting frame 9 and on the periphery of the limiting rod 13. A guide plate 17 is fixedly installed on the front of the movable plate 12. A symmetrical L-shaped guide groove 19 is provided on the front of the first partition 1. The guide plate 17 and the L-shaped guide groove 19 are slidably connected. A fixing device 20 is provided at both the top and bottom of the first partition 1.

[0016] Example 2: As shown in the attached diagram of the instruction manual. Figure 1 , Figure 2 and Figure 3As shown, when using an integrated high-current busbar bushing, the positioning hole 16 at one end of the first partition 1 is first fitted and inserted into the positioning plate 14 at the other end of the second partition 2, thereby facilitating quick guiding and positioning between the first partition 1 and the second partition 2. Then, by pulling the guide plate 17, the guide plate 17 is slid into the appropriate position within the L-shaped guide groove 19. Next, the guide plate 17 is released, and due to the action of the spring 18, the limiting rod 13 will insert into the limiting hole 15 on the surface of the positioning plate 14, thereby fixing the first partition 1 and the second partition 2. This solves the problem that existing busbar bushings are usually fixed by the engagement of the busbar and the busbar hole during installation. However, due to the small gap between the busbar and the busbar hole, and the limited position when installing the busbar, the operation of inserting it into the busbar hole is difficult, the adjustment of the hole during installation is even more difficult, and the disassembly is also more complicated. Then, by turning the handwheel 20.3, the threaded rod 20.2 is rotated to a suitable position, so that the threaded rod 20.2 is locked on the support plate 20.1. Then, the nut 20.4 is tightened, thereby further improving the fixation of the first partition 1 and the second partition 2.

[0017] The stability of the limit rod 13 is improved by symmetrical sliding rods 10 inside the limit frame 9 and sliders 11 fixedly installed at both ends of the movable plate 12, and by the sliders 11 sliding on the sliding rods 10.

[0018] The inner sleeve 3 is provided with an insulating outer sleeve 4 on its outer wall to isolate the inner sleeve 3 and prevent leakage. Several creepage skirts 5 are evenly provided on the outer surface of the insulating outer sleeve 4 to prevent creepage.

[0019] In use, when it is necessary to disassemble the first partition 1 and the second partition 2, first loosen the nut 20.4, then turn the handwheel 20.3 in the opposite direction. The handwheel 20.3 will turn the threaded rod 20.2 in the opposite direction, separating the threaded rod 20.2 from the support plate 20.1. Then, by pulling the guide plate 17, the guide plate 17 will slide in the L-shaped guide groove 19 to a suitable position. At this time, the guide plate 17 will drive the limiting rod 13 to move through the movable plate 12. The movable plate 12 will stretch the spring 18, thereby making the limiting rod 13 move away from the limiting hole 15 opened on the surface of the positioning plate 14, thereby disassembling the first partition 1 and the second partition 2.
