Description

Technical Field

[0001] This utility model relates to the field of busbar protection technology, specifically to a closed busbar protection device. Background Technology

[0002] In power systems, busbars are crucial for the safe and stable operation of electrical energy collection and distribution. Busbar protection devices are the core equipment to ensure the safe operation of busbars. They can quickly and accurately disconnect faults when they occur on the busbars, prevent the fault range from expanding, and ensure the stability and reliability of the power system.

[0003] Traditional busbar protection devices have a relatively fixed overall structure, generally consisting of several connecting frames and several protective plates that are fixed with screws. Furthermore, the connecting frames are assembled and connected by several right-angle connecting rods and screws. During the installation process, several screws need to be connected, which is quite wasteful of installation time and has low installation efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing busbar protection devices have a fixed structure, consisting of several connecting frames, protective plates, and right-angle connecting rods, all assembled with screws. Installation requires connecting numerous screws, consuming a significant amount of time and resulting in extremely low overall installation efficiency.

[0005] To solve the above problems, the technical solution adopted by this utility model is a closed busbar protection device, including four connecting rods. Protective plates are provided on both sides and the bottom of the four connecting rods. Slots are opened at the four corners of the connecting rods. Cylindrical grooves are opened at the bottom of the slots. Bending plates are fixed to the edges of the protective plates. Semicircular clips are fixed to one end of the bending plates. The two semicircular clips can be locked in the cylindrical grooves for position fixation. Support structures are provided on the inner side of the four connecting rods.

[0006] The support structure includes a support frame, with plug-in plates fixed at both ends of the support frame to mate with slots and cylindrical slots, so as to facilitate the installation of the support frame. A busbar limiting frame is inserted inside the support frame.

[0007] As a further embodiment of this utility model: the top of the four connecting rods is provided with a heat dissipation plate, and is connected and fixed by a bent plate and a semi-circular clip inserted into the slot and the cylindrical slot, so as to facilitate heat dissipation of the entire protective frame.

[0008] As a further embodiment of this utility model: the busbar limiting frame includes a plug-in plate, and the plug-in plate has several limiting holes on its side to limit the position of the busbar.

[0009] As a further embodiment of this utility model, the two ends of the support frame are positioned between adjacent connecting rods on both sides, which can improve the overall support strength of the protective frame.

[0010] As a further aspect of this utility model, the connection between the connecting rod and the protective plate is sealed with sealant to ensure the airtightness of the busbar protection frame.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This application adds a connecting rod and a protective plate structure, and connects them by inserting a bent plate and a semi-circular clip into the slot and cylindrical slot, as well as a plug-in busbar connection frame and heat dissipation plate, which can simplify the installation process, facilitate assembly, and save a lot of installation time.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0021] Referring to Figure 4, it can be seen that the system includes four connecting rods 1, with protective plates 2 on both sides and bottom of the four connecting rods 1, and heat dissipation plates 8 at the top of the four connecting rods 1. These are connected and fixed by bending plates 3 and semi-circular clips 4 inserted into slots 1.1 and cylindrical slots 1.2 to facilitate heat dissipation for the entire protective frame. Slots 1.1 are opened at the four corners of the connecting rods 1, and cylindrical slots 1.2 are opened at the bottom of each slot 1.1. Bending plates 3 are fixed to the edges of the protective plates 2, and semi-circular clips 4 are fixed to one end of each bending plate 3. The two semi-circular clips 4 can be clamped into the cylindrical slots 1.2 for position fixation. The connection between the connecting rods 1 and the protective plates 2 is sealed with sealant to ensure the airtightness of the inside of the busbar protective frame.

[0022] Combined with appendix Figure 1 , 2 It can be seen that the inner sides of the four connecting rods 1 are equipped with support structures; the support structures include support frames 5, the two ends of the support frames 5 are set between the adjacent connecting rods 1 on both sides, which can improve the overall support strength of the protective frame. The two ends of the support frames 5 are fixed with plug-in plates 6 that cooperate with the slots 1.1 and cylindrical slots 1.2 to facilitate the installation of the support frames 5. The inner side of the support frames 5 is equipped with busbar limiting frames 7, which include plug-in plates 6. The plug-in plates 6 have several limiting holes on their sides to limit the position of the busbar.

[0023] The working principle of this application is as follows: During installation, the protective plate 2, equipped with a bending plate 3 and a semi-circular retaining strip 4, is placed on both sides and the bottom of the four connecting rods 1, so that the semi-circular retaining strip 4 is clamped in the cylindrical groove 1.2 at the bottom end of the slot 1.1 at the four corners of the connecting rod 1, thereby fixing the position of the protective plate 2 and the connecting rod 1. Unlike traditional devices, it does not require the connection of numerous screws, saving installation time and improving installation efficiency. The plug-in plates 6 at both ends of the support frame 5 are inserted into the slots 1.1 and cylindrical grooves 1.2 on the connecting rod 1, completing the installation of the support frame 5 inside the four connecting rods 1. The two ends of the support frame 5 are positioned between the adjacent connecting rods 1 on both sides, which can improve the overall support strength. The busbar limiting frame is then installed. 7. Insert the support frame 5 inside, and use the several limiting holes on the side of the plug plate 6 on the busbar limiting frame 7 to accurately limit the busbars of different specifications, ensuring the stable fixation of the busbars in the device; if a heat dissipation plate 8 is provided, the heat dissipation plate 8 is inserted into the slot 1.1 and cylindrical slot 1.2 at the top of the connecting rod 1 through the bending plate 3 and the semi-circular clip 4 for connection and fixation. When the busbar generates heat during operation, the heat dissipation plate 8 can dissipate the heat in time and reduce the busbar temperature; apply sealant to the connection between the connecting rod 1 and the protective plate 2 to seal it, ensuring the airtightness of the inside of the busbar protective frame, preventing dust, moisture and other external substances from entering, and protecting the busbar from external environmental damage.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
