Description

Technical Field

[0001] This utility model relates to the field of cabinet structure technology, and in particular to an electrical installation protection cabinet. Background Technology

[0002] To prevent accidental electric shock during electrical work, insulating protective plates are typically installed on the high-voltage side of electrical cabinets to shield exposed live parts such as copper busbars, eliminating the risk of accidental electric shock and ensuring the safety of electrical operators and maintenance personnel. For example... Figure 9 Traditional installation methods often involve using multiple metal screw assemblies A to support the protective plate B. This method requires welding or riveting nuts onto the cabinet base plate to install the screw assemblies A, which are then cut to the required length. Furthermore, the layout of electrical components must consider the clearance of the screw assemblies A, increasing the complexity of electrical layout planning. Additionally, protective plates installed using metal screws A may experience bending during transportation; the longer the screw A, the easier it is to bend. Bending could lead to contact with live parts, causing short circuits or electrical leaks, posing safety hazards. Utility Model Content

[0024] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] This embodiment discloses an electrical installation protection cabinet for installing electrical components, which is particularly suitable for the centralized installation and arrangement of high-voltage side components.

[0026] like Figures 1 to 6 In this embodiment, the protective cabinet includes a cabinet body 1 and a protective panel 2. The cabinet body 1 includes a bottom wall 10 and a side wall 11 surrounding the bottom wall 10. A cavity 12 for installing electrical components is formed between the bottom wall 10 and the side wall 11.

[0027] The cabinet 1 also includes a window 13 (e.g., a window 13) disposed opposite to the bottom wall 10 and communicating with the cavity 12. Figure 2 Through this window 13, relevant components can be sent into or taken out of the cavity 12.

[0028] A connector 3 is provided at the edge of the window 13, and the protective plate 2 is detachably connected to the cabinet 1 through the connector 3. Furthermore, there is a gap D between the side of the protective plate 2 facing away from the bottom wall 10 and the window 13 (e.g., ...). Figure 3 The protective plate 2 is recessed into the cavity 12, and the protective plate 2 is an insulating plate. This protective plate 2 is used to prevent personnel from accidentally touching the electrical components inside the cabinet 1 when they approach it, thus ensuring the safety performance of the cabinet.

[0029] In this embodiment, the protective plate 2 is connected to the cabinet 1 via the connector 3 located at the window 13. In this way, compared with the traditional fixing method using screws on the bottom plate of the cabinet 1, the installation of the protective plate 2 can effectively avoid affecting the layout of electrical components in the cavity 12 of the cabinet 1, and the safety performance is effectively improved.

[0030] On the other hand, such as Figure 3 , Figure 5 and Figure 6The connector 3 has a Z-shaped structure and includes a first connecting part 30, a second connecting part 31, and a transition part 32 located between the first connecting part 30 and the second connecting part 31. The first connecting part 30 is connected to the edge of the window 13, the second connecting part 31 is connected to the protective plate 2, and the transition part 32 extends towards the bottom wall 10 so that the second connecting part 31 is located inside the cavity 12. In this embodiment, the protective plate 2 is suspended at the window 13 by the Z-shaped connector 3. The connector 3 is only located at the window 13 and will not affect the installation layout of the components inside the cavity 12.

[0031] On the other hand, the second connecting part 31 is provided with a connecting post 33, and the protective plate 2 is provided with a connecting hole 20 that is adapted to the connecting post 33 (e.g., Figure 4 With the cooperation of the connecting post 33 and the connecting hole 20, the protective plate 2 is hung on the connecting piece 3, which facilitates installation and disassembly.

[0032] In addition, the connecting post 33 is cylindrical and the connecting hole 20 is waist-shaped, which can effectively reduce the fitting accuracy between the multiple connecting parts 3 and the connecting hole 20 on the protective plate 2.

[0033] Furthermore, to ensure the stability of the protective plate 2, four connectors 3 are provided at intervals around the perimeter of the window 13, and correspondingly, four connection holes 20 are provided on the protective plate 2.

[0034] On the other hand, the protective panel 2 is a transparent structural component, so that staff can view the inside of the cabinet 1 without removing the protective panel 2.

[0035] On the other hand, in order to facilitate the installation of the circuit breaker operating handle, the protective plate 2 is provided with a clearance hole 21, which is used for the extension of the circuit breaker operating handle installed in the cavity 12.

[0036] On the other hand, since the protective panel 2 is located inside the cavity 12, that is, the area of ​​the protective panel 2 is smaller than the area of ​​the window 13, in order to prevent debris from entering the cavity 12 inside the cabinet 1, such as Figure 7 and Figure 8 The window 13 is also provided with an openable cabinet door 4, which is used to close the window 13.

[0037] In response, Figures 1 to 3 as well as Figure 8 To facilitate the installation and opening of the cabinet door 4, the periphery of the window 13 is provided with an outwardly bent hanging plate 14, and the inner periphery of the cabinet door 4 is provided with a hanging groove 40 that matches the hanging plate 14.

[0038] In addition, such as Figure 1 and Figure 2 The side wall 11 is also provided with an exhaust hole 5 so that the heat generated by the components in the cavity 12 can be quickly dissipated.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
