Description

Technical Field

[0001] This invention relates to the field of busbar bridge structure technology, specifically to busbar bridge structure and wiring modification methods. Background Technology

[0002] As is well known, a busbar bridge, also known as a bridge connection, is a main connection that uses a jumper circuit breaker to connect two power supply lines to two transformers. In a power system, it serves to connect the busbars of different switchgear.

[0003] A search revealed that Chinese patent application CN201921937050.7 discloses a novel co-directional inter-cabinet busbar bridge structure. It is broadly described as including A1-phase busbars, A2-phase busbars, B1-phase busbars, B2-phase busbars, C1-phase busbars, and C2-phase busbars located within the busbar bridge housing. The A1-phase, B1-phase, and C1-phase busbars increase in height from the outside in, with their lower ends connecting to the corresponding reserved busbars on the top of cabinet G1. The A2-phase, B2-phase, and C2-phase busbars increase in height from the inside out, with their lower ends connecting to the corresponding busbars on the top of cabinet G2. This structure effectively prevents the A-phase, B-phase, and C-phase busbars from intersecting with the A1-phase, A2-phase, B1-phase, B2-phase, C1-phase, and C2-phase busbars, thus ensuring the normal operation of the device. Chinese patent application CN202121159975.0 discloses a busbar bridge structure, which is roughly described as including a main busbar and several auxiliary busbars. The main busbar includes a connection end, a transmission section, and a parallel connection end connected in sequence. The connection end is connected to a transformer, and the parallel connection end is connected to one of the switch cabinets. One end of each auxiliary busbar is connected to another switch cabinet, and the other end of each auxiliary busbar is connected to the parallel connection end. The busbar bridge is installed on the busbar. The busbar bridge structure can reduce the length of the busbar, simplify the layout of the busbar, reduce the processing cost and material cost of the busbar, and save the space occupied by the busbar. It is also simple in structure and easy to install. By setting the busbar bridge installed outside the busbar, it plays a role in protecting the busbar and improving the safety factor of the busbar bridge structure.

[0004] Although the above-mentioned existing technical solutions provide two busbar bridge structures, the connection points of both are assembled and connected by bolts or similar bolt structures. Once installed and put into use, if further modification is required, it can only be done with special tools or after power is cut off, resulting in poor flexibility in use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a busbar bridge structure and wiring modification method. The connection points adopt a more flexible connection structure, ensuring normal operation while using a quick-release structure, making the connection operation faster, the modification work more convenient, and more practical.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a busbar bridge structure, comprising two line bridges and two connecting components. Each of the two connecting components includes an insertion connector and a contact connection frame. The two insertion connectors are respectively fixedly connected to the two line bridges, and the two contact connection frames are also respectively fixedly connected to the two line bridges. The insertion connector matches the contact connection frame. An insulating hook plate is slidably fitted on the contact connection frame. The insulating hook plate matches the insertion connector. A connecting spring is installed on the insulating hook plate through a quick-release assembly. The connecting spring is connected to the contact connection frame.

[0007] Preferably, the insulating hook plate is provided with a sheet metal bending lug, and a fixing plate is fixedly connected to the sheet metal bending lug by connecting bolts, and the fixing plate is fixedly connected to the connecting spring.

[0008] Preferably, the quick-installation assembly includes an insulating operating frame and a sheet metal bending strip, the sheet metal bending strip is disposed on the contact connection frame, the insulating operating frame is detachably mounted on the sheet metal bending strip, and the insulating operating frame is fixedly connected to the connecting spring.

[0009] Preferably, the sheet metal bending strip is fixedly connected to a semi-circular frame, and a rotating rod is rotatably connected between the semi-circular frame and the sheet metal bending strip. The rotating rod is fixedly connected to a vertical rod, and a pivot pin is fixedly connected to the vertical rod. A strip-shaped hole matching the pivot pin is opened on the sheet metal bending strip. A disc spring is fixedly connected inside the insulating operating frame, and the disc spring is fixedly connected to the rotating rod.

[0010] Preferably, the contact connection frame is fixedly connected to a conductor pressure plate, and the insulating hook plate is fixedly connected to an insulating pressure plate. Both the insulating pressure plate and the conductor pressure plate are provided with multiple insertion holes, and the insertion connector is provided with multiple insertion posts that match the insertion holes.

[0011] Preferably, the contact connection frame is provided with two upper flip-up hooks and two lower flip-up hooks, and both the two upper flip-up hooks and the two lower flip-up hooks are matched with the insulating hook plate.

[0012] Preferably, the insulating hook plate is provided with two upper disassembly notches and two lower disassembly notches, the two upper disassembly notches respectively matching two upper flange hooks, and the two lower disassembly notches respectively matching two lower flange hooks.

[0014] Preferably, the rotating rod is fixedly connected to an insulated wire operating ring, and the insulated hook plate is provided with two split sheet metal push plates.

[0015] The method for modifying the busbar bridge structure includes the following steps:

[0016] S1. In actual use, by applying a force to overcome the connecting spring, the connecting spring can be elastically stretched to achieve relative displacement between the contact connecting frame and the insulating hook plate, so that there is space between the contact connecting frame and the insulating hook plate to allow the insertion of the connector. After the connector is inserted into place, the force applied to the connecting spring is released. Under the action of the connecting spring, the contact connecting frame and the insulating hook plate can be pressed and positioned relative to the inserted connector, and then the two line bridges can be electrically connected.

[0017] S2. When it is necessary to modify the electrical connection between two line bridges, simply apply the force to overcome the connecting spring again to disable the pressing and positioning effect of the contact connection frame and the insulating hook plate relative to the insertion connector.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] For examples, please refer to Figures 1-12 The busbar bridge structure includes two line bridges 1 and two connecting assemblies. Each connecting assembly includes an insertion connector 2 and a contact connection frame 3. The two insertion connectors 2 are fixedly connected to the two line bridges 1 respectively, and the two contact connection frames 3 are also fixedly connected to the two line bridges 1 respectively. The insertion connectors 2 and contact connection frames 3 are matched. An insulating hook plate 4 is slidably fitted on the contact connection frame 3, and the insulating hook plate 4 is matched with the insertion connector 2. A conductor pressure plate 17 is fixedly connected to the contact connection frame 3, and an insulating pressure plate 18 is fixedly connected to the insulating hook plate 4. Multiple insertion holes 19 are provided on both the insulating pressure plate 18 and the conductor pressure plate 17. Multiple insertion posts 20 matching the insertion holes 19 are provided on the insertion connectors 2. A connecting spring 5 is installed on the insulating hook plate 4 via a quick-release assembly, and the connecting spring 5 is connected to the contact connection frame 3. The design of the connecting assemblies provides a functional structure for mutual end-to-end connection between the two line bridges 1, facilitating electrical connection between them. The insulating hook plate 4 is provided with a sheet metal bend. A fixed plate 8 is fixedly connected to the bent sheet metal ear 6 via connecting bolts 7. The fixed plate 8 is fixedly connected to the connecting spring 5. The quick-installation assembly includes an insulating operating frame 10 and a bent sheet metal strip 9. The bent sheet metal strip 9 is set on the contact connecting frame 3. The insulating operating frame 10 is detachably installed on the bent sheet metal strip 9. The insulating operating frame 10 is fixedly connected to the connecting spring 5. With the matching of the quick-installation assembly, the connecting spring 5 can be quickly installed between the insertion connector 2 and the contact connecting frame 3. For easy assembly and adjustment between the connector 2 and the contact frame 3, the sheet metal bending strip 9 is fixedly connected to a semi-circular frame 11. A rotating rod 12 is rotatably connected between the semi-circular frame 11 and the sheet metal bending strip 9. A vertical rod 13 is fixedly connected to the rotating rod 12. A pivot pin 14 is fixedly connected to the vertical rod 13. A strip hole 15 matching the pivot pin 14 is opened on the sheet metal bending strip 9. A disc spring 16 is fixedly connected inside the insulating operating frame 10. The disc spring 16 is fixedly connected to the rotating rod 12.

[0037] It should be further explained that the contact connection frame 3 is equipped with two upward-flipping hooks 21 and two downward-flipping hooks 22. Both the two upward-flipping hooks 21 and the two downward-flipping hooks 22 are matched with the insulating hook plate 4. The two upward-flipping hooks 21 and the two downward-flipping hooks 22 work together to form a hook guide rail that matches the insulating hook plate 4. The insulating hook plate 4 is equipped with two upward disassembly notches 23 and two downward disassembly notches 24. The two upward disassembly notches 23 are matched with the two upward-flipping hooks 21 respectively, and the two downward disassembly notches 24 are matched with the two downward-flipping hooks 22 respectively. The insulating hook plate 4 is slidably adjusted relative to the contact connection frame 3 so that the two upward-flipping notches 23 overlap with the two upward-flipping hooks 21 respectively, and the two downward-flipping notches 24 overlap with the two downward-flipping hooks 22 respectively. When the two upper and lower hooks 21 are aligned, the insulating hook plate 4 can be removed from the track formed by the two upper hooks 21 and the two lower hooks 22. Similarly, the opposite operation can be performed to insert the insulating hook plate 4 into the track formed by the two upper hooks 21 and the two lower hooks 22. Both wire bridges 1 are provided with double-sided flaps 25, and each double-sided flap 25 is provided with two light holes 26. Each light hole 26 is provided with an insertion screw 27. Each insertion connector 2 is provided with two threaded grooves 28. The four insertion screws 27 are respectively matched with the four threaded grooves 28. The rotating rod 12 is fixedly connected with an insulating wire operating ring 29 to facilitate the rotation adjustment of the rotating rod 12. The insulating hook plate 4 is provided with two split sheet metal push plates 30 to facilitate the pushing and pulling of the insulating hook plate 4.

[0038] In summary, the working principle of this busbar bridge structure and wiring modification method is as follows: In actual use, by applying a force to overcome the connecting spring 5, the connecting spring 5 is elastically stretched, which realizes the relative displacement between the contact connecting frame 3 and the insulating hook plate 4. This creates space between the contact connecting frame 3 and the insulating hook plate 4 to allow the insertion of the connector 2. After the connector 2 is inserted into place, the force applied to the connecting spring 5 is released. Under the action of the connecting spring 5, the contact connecting frame 3 and the insulating hook plate 4 can be pressed and positioned relative to the connector 2. Afterward, an electrical connection can be achieved between the two line bridges 1. When it is necessary to modify the connection between the two line bridges 1... When modifying the electrical connection between the two line bridges 1, it is only necessary to apply the force of the overcoming spring 5 again to disable the pressing and positioning effect of the contact connecting frame 3 and the insulating hook plate 4 relative to the insertion connector 2. After that, the connection structure between the two line bridges 1 can be modified. During the modification of the connection structure between the two line bridges 1, when the new line bridge 1 is connected to the two original line bridges 1, it is only necessary to match the insertion connector 2 on the new line bridge 1 with the contact connecting frame 3 and the insulating hook plate 4 on the original line bridge 1 to form a corresponding connection.

[0039] Furthermore, when applying a force to the insulating hook plate 4 relative to the contact connecting frame 3, the force can be applied by gripping the two split sheet metal push plates 30 on the insulating hook plate 4. Before the contact connecting frame 3 and the insulating hook plate 4 can slide and disassemble, the connecting spring 5 needs to be disassembled relative to the sheet metal bending strip 9. At this time, the operator only needs to hook the insulating wire operating ring 29 with their finger and apply a rotational force to the insulating wire operating ring 29, so that the rotating rod 12 can rotate and adjust between the insulating operating frame 10 and the semi-circular frame 11. The rotation of the rotating rod 12 drives the vertical rod 13 to rotate, and the rotation of the vertical rod 13 drives the rotating pin 14 to rotate. When the rotating pin 14 is completely rotated out of the strip hole 15, the insulating operating frame 10 can be pulled out relative to the sheet metal bending strip 9, thereby allowing the connecting spring 5 to disassemble from the sheet metal bending strip 9. When the connection between them fails, the insulating hook plate 4 can be slid off relative to the contact connecting frame 3. When assembling the contact connecting frame 3 and the insulating hook plate 4, the insulating operating frame 10 is re-inserted with the sheet metal bending strip 9. Finally, the insert pin 14 is rotated and inserted into the strip hole 15. At this time, the insulating operating frame 10 is inserted and positioned relative to the sheet metal bending strip 9, thus completing the connection between the connecting spring 5 and the contact connecting frame 3. Since the connecting spring 5 is inclined between the insert connector 2 and the contact connecting frame 3, the connecting spring 5 can not only realize the relative sliding limit between the insert connector 2 and the contact connecting frame 3, but also promote the tightness of the fit between the insert connector 2 and the contact connecting frame 3, and improve the accuracy of the direction when adjusting the relative position between the conductor pressure plate 17 and the insulating pressure plate 18.
