Description

Technical Field

[0001] This utility model relates to the field of assembled low-voltage switchgear technology, specifically an assembled low-voltage switchgear that is easy to install. Background Technology

[0002] Low-voltage switchgear, also known as low-voltage distribution cabinet, typically operates on a voltage level of 400 volts. The cabinet is usually made of thin steel plate, and its function is generally limited to power distribution. Internally, it typically contains only a few circuit breakers, serving as a protective switch. The main purpose of low-voltage switchgear is to switch, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes within a power system. The main components of a low-voltage switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices.

[0003] The prior art, disclosed in CN218997415U, provides an easily installable modular low-voltage switchgear, comprising a base plate. A second low-voltage switchgear assembly front plate, a first low-voltage switchgear assembly rear plate, and two second low-voltage switchgear assembly side plates are mounted in a rectangular array on the upper end of the base plate. The lower end face of the second low-voltage switchgear assembly front plate is fixedly connected to the base plate. The lower end faces of the first low-voltage switchgear assembly rear plate and the two second low-voltage switchgear assembly side plates are all abutted against the upper end face of the base plate. The two second low-voltage switchgear assembly side plates are symmetrically and detachably fixedly installed at the left and right ends of the second low-voltage switchgear assembly front plate. The first low-voltage switchgear assembly rear plate is detachably and fixedly installed between the two second low-voltage switchgear assembly side plates, located behind the second low-voltage switchgear assembly front plate. This invention facilitates disassembly and assembly, is simple to operate, has low manufacturing costs, and is easy to promote and use.

[0004] The aforementioned patent mainly uses multiple sets of set screws and bolts to facilitate the assembly of the entire low-voltage switchgear. However, when disassembling the entire low-voltage switchgear, multiple sets of set screws and bolts need to be removed together, which directly makes the disassembly process of the entire low-voltage switchgear quite cumbersome. Furthermore, the removed set screws and bolts need to be kept to prevent loss, thus reducing the practicality of the assembled low-voltage switchgear. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an easy-to-install modular low-voltage switchgear, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install modular low-voltage switchgear includes a main body assembly. Side panel assemblies are inserted into both sides of the main body assembly, a top cover assembly is inserted into the top of each side panel assembly, and a front panel assembly is inserted into the front end of each side panel assembly. The front panel assembly and the top cover assembly are interlocked. The main body assembly includes a base plate, with a rear plate inserted into the end of the base plate away from the front panel assembly. Each side panel assembly includes a side plate inserted into the base plate. Elastic components are disposed within the rear plate and side panels, and both the rear plate and side panels are interlocked with these elastic components. The interlocking of the rear plate and side panels with the elastic components allows the elastic components to apply an elastic tension force to the rear plate and side panels, thereby improving the overall compressive strength of the easy-to-install modular low-voltage switchgear.

[0007] Furthermore, the elastic component includes a first block and a second block located within the rear plate and side plate, respectively. A cylindrical groove is formed at the center of the opposing surfaces of the first and second blocks. A sleeve is disposed within the cylindrical groove, and telescopic shafts are fixedly installed on both sides of the sleeve. An adhesive disc is fixedly installed at the end of the telescopic shaft away from the sleeve, and the adhesive disc is fixedly adhered to the inner wall of the cylindrical groove of the second block. A spring is disposed between the sleeve and the adhesive disc, and the spring is located around the outside of the telescopic shaft. The spring's location around the outside of the telescopic shaft allows the second block to move on the sleeve via the telescopic shaft, improving the integrated operation of the internal structure of the easily assembled low-voltage switchgear.

[0008] Furthermore, the rear plate has first slots inclined on both sides, and the side plate has a second slot inclined on the side near the rear plate. Both the rear plate and the side plate have insertion slots, which are connected to the first and second slots. The elastic component is located in the first and second slots and enters the first and second slots through the insertion slots.

[0009] Furthermore, the rear plate is fixedly mounted on a fixing plate on both sides, with one end of the fixing plate away from the rear plate located in a second slot, and the elastic component placed on the fixing plate.

[0010] Furthermore, the rear panel has multiple heat dissipation holes for cooling electronic components, and the side panel has a mounting groove at the end away from the front panel assembly. The rear panel is inserted into the mounting groove, and the bottom plate has multiple rectangular slots. Rectangular inserts are fixedly connected to the bottom of both the rear panel and the side panel, and these inserts are inserted into the rectangular slots of the bottom plate for fixation. This method of fixing the rectangular inserts at the bottom of the rear panel and side panel into the rectangular slots of the bottom plate makes the internal structure of the easily installable modular low-voltage switchgear more robust and reliable, improving the operational stability of the modular low-voltage switchgear.

[0011] Furthermore, the front end of the side panel is provided with a front straight groove, the front panel assembly includes a front panel body, and the front panel body has insert plates on both sides of the side panel assembly. The insert plates are inserted into the front straight groove and fixed. A swing door is installed in the front panel body.

[0012] Furthermore, a top groove is formed at the center of the top of the front panel. The top cover assembly includes a top plate. A front insert is fixedly installed at one end of the top plate near the front panel assembly, and the front insert is inserted into the top groove for fixation. A rear insert for connecting the rear panel is fixedly installed at the other end of the top plate away from the front insert. Side inserts for connecting side panels are formed on both sides of the top plate. A counterweight is fixedly installed on the top of the top plate. The counterweight fixedly installed on the top of the top plate makes the assembled low-voltage switchgear more stable. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model assembles a modular low-voltage switchgear by interlocking the main body assembly, side panel assembly, top cover assembly, and front panel assembly. During assembly, the rear panel and side panels are reinforced and fixed by elastic components. This makes the modular low-voltage switchgear easier to install and remove, and eliminates the need for top screws and bolts during overall installation, thus improving its practicality.

Telescopic shafts 174 are fixedly installed on both sides of the sleeve 177. An adhesive disc 175 is fixedly installed at the end of the telescopic shaft 174 away from the sleeve 177. The adhesive disc 175 is fixedly adhered to the inner wall of the cylindrical groove 172 of the second block 173. A spring 176 is provided between the sleeve 177 and the adhesive disc 175. The spring 176 is located around the telescopic shaft 174. First slots 14 are obliquely provided on both sides of the rear plate 12. A second slot 24 is obliquely provided on the side of the side plate 22 near the rear plate 12. Insertion slots 15 are provided on both the rear plate 12 and the side plate 22. The insertion slots 15 are connected to the first slots 14 and the second slots 24. The elastic component 17 is located in the first slot 14 and the second slot 24. The elastic component 17 enters the first slot 14 and the second slot 24 through the insertion slot 15. The rear plate 12 is fixedly mounted on the fixing plate 16 on both sides. The end of the fixing plate 16 away from the rear plate 12 is located in the second slot 24. The elastic component 17 is placed on the fixing plate 16. The rear plate 12 has a plurality of heat dissipation holes 13 for heat dissipation of electronic components. The side plate 22 has a mounting slot 23 at the end away from the front plate assembly 4. The rear plate 12 is inserted into the mounting slot 23. The bottom plate 11 has a plurality of rectangular slots.

[0022] The working principle of this utility model is explained below: When assembling the easy-to-install modular low-voltage switchgear, the user first inserts the side panel 22 and the rear panel 12 into the base plate 11 via a plug-in connection. At this time, the rear panel 12 is inserted into the mounting groove 23 of the side panel 22. Then, the user compresses both ends of the elastic component 17, causing the first block 171 and the second block 173 to move towards the sleeve post 177 via the spring 176. The elastic component 17 is then inserted into the first slot 14 and the second slot 24 via the insertion slot 15. Finally, the user inserts the front panel 41 into the side panel. The front end of panel 22 is fixed, and finally the top plate 31 is placed on the front panel 41, the rear panel 12 and the side panel 22. At this time, the side plug 33 is inserted into the side panel 22, the rear plug 32 is inserted into the rear panel 12, and the front plug 35 is inserted into the top groove 42. This completes the installation of the easy-to-install modular low-voltage switchgear. This makes the easy-to-install modular low-voltage switchgear easier to install and remove, and eliminates the need for top screws and bolts during the overall installation, thus improving the practicality of the easy-to-install modular low-voltage switchgear.
