Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinets, specifically to a prefabricated power distribution cabinet. Background Technology

[0002] A distribution cabinet is an important piece of equipment used for power distribution, control, and protection. Its main functions include receiving power from the main power distribution line and distributing it to various electrical devices through branch circuits. The distribution cabinet can regulate power supply by controlling the connection and disconnection of the power source to ensure the normal operation of electrical equipment. Furthermore, distribution cabinets can be equipped with overvoltage, undervoltage, and overcurrent protection devices; in the event of an abnormality, the distribution cabinet will automatically disconnect the power supply to protect the electrical equipment.

[0003] The distribution cabinet contains multiple electrical components. Existing distribution cabinets connect multiple electrical components inside the cabinet to coordinate their operation. This connection method results in messy cables and inconvenient installation. It may also lead to poor air circulation, affecting heat dissipation and consequently impacting the overall performance and lifespan of the distribution cabinet. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] like Figure 1-3 As shown, the present invention proposes a prefabricated combined power distribution cabinet, including an outer cabinet 11 and an inner cabinet 12 disposed inside it. The outer cabinet 11 and the inner cabinet 12 are connected by symmetrical horizontal plates 21, and an "L-shaped" track plate 22 is disposed between two opposing horizontal plates 21.

[0024] The inner cabinet 12 has a first module 3 and a second module 4 arranged in a matching manner on the upper and lower layers;

[0025] The positioning mechanism includes a side plate 51 disposed on the side wall of the first module 3 and the second module 4, a guide slide 52 installed on the other side of the side plate 51, and a suspension slide 53 disposed above it.

[0026] The combined mechanism includes a cylinder 61 located at the bottom of the first module 3. A piston rod 62 is installed at the output end of the cylinder 61. The other end of the piston rod 62 is connected to a suspension plate 63. A power connection terminal 64 that moves along the inner cavity of the suspension plate 63 is connected to one side of the suspension plate 63. Several protruding end posts 65 are provided at the bottom of the power connection terminal 64. An end post platform 66 installed on the upper part of the second module 4 is provided below the end posts 65.

[0027] It should be noted that:

[0028] 1. The upper and lower parts of the guide slide 52 are respectively embedded in the grooves of the horizontal plate 21 and the track plate 22. The first module 3 slides synchronously with the guide slide 52. The first module 3 and the second module 4 can be respectively slid into the placement area between adjacent horizontal plates 21 through the guide slide 52.

[0029] 2. The suspension slide 53 is installed on the top of the first module 3 and the second module 4, and the gap between the suspension slide 53 and the guide slide 52 is the same as the thickness of the horizontal plate 21. After the guide slide 52 is used for initial fixation, the suspension structure between the suspension slide 53 and the horizontal plate 21 is increased to serve as the upper support structure to bear the force, thereby improving the installation stability of the first module 3 and the second module 4.

[0030] In this embodiment, the first module 3 and the second module 4 are installed in the placement area between adjacent horizontal plates 21. The first module 3 and the second module 4 are modular structures with pre-installed electrical components. Only the combination mechanism is reserved for the combination between modules. The piston rod 62 at the output end of the cylinder 61 drives the suspension plate 63 to move. The power terminal 64 moves synchronously with the suspension plate 63 until the end post 65 at the bottom is embedded in the end post platform 66. Each end post 65 is inserted into the respective slot of the end post platform 66 to perform the combination and assembly between modules, realizing the function of the power distribution cabinet. There is no need for traditional complex cable connections. Moreover, during maintenance, the power distribution cabinet can be de-energized and the modules can be maintained simply by separating the end post 65 and the end post platform 66.

[0031] It is understandable that the end faces of the end post 65 and the end post platform 66 that are in contact are conductive metal structures, and current is transmitted through the metal structure.

[0032] To further protect the end post 66, a raised enclosure 7 is provided around the outer perimeter of the end post 66.

[0033] In one embodiment, a gap is left between the outer cabinet 11 and the inner cabinet 12. The gap is divided into several sections by a horizontal plate 21. The gap can be expanded to install heat dissipation modules and functional modules. Another purpose of the gap is heat dissipation, and the cavity design facilitates heat dissipation.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
