Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[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 the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0023] See Figure 1-5 The purpose of this utility model is to provide a switch cabinet for displaying the opening and closing status, including a main body 1, which is a metal outer shell of a distribution box. A vertical opening and closing door 2 and a side opening and closing door 3 are installed on one side of the main body 1, with the vertical opening and closing door 2 located on top of the side opening and closing door 3. A partition 11 is provided between the vertical opening and closing door 2 and the side opening and closing door 3 on the main body 1.
[0024] Specifically, the main body 1 has two openings corresponding to the vertical opening door 2 and the side opening door 3, respectively. The two openings are separated by a partition 11, so that the staff can install various equipment inside the main body 1 through the openings. The vertical opening door 2 is equipped with several indicator lights for indicating the opening and closing status and control buttons and other components. The openings corresponding to the vertical opening door 2 can be used to pass through power lines and make electrical connections with the indicator lights for the opening and closing status and control buttons and other components.
[0025] Both the vertically opening door 2 and the side-opening door 3 are hinged to the main body 1. The bottom edge of the vertically opening door 2 is hinged to the main body 1, allowing it to open and close vertically on the main body 1. The side edge of the side-opening door 3 is hinged to the main body 1, allowing it to open and close horizontally on the main body 1. The vertically opening door 2 ensures that it occupies less space when opening and closing. The main body 1 is internally fixedly connected to a mounting bracket 4 and several cable management channels 5. The cable management channels 5 include vertical cable channels 51 installed vertically on the inner side wall of the main body 1 and horizontally installed opening and closing door cable channels 52 on the partition 11.
[0026] Therefore, this switchgear, with its vertically opening and closing door 2, occupies less space during opening and closing, making it particularly practical for situations with limited workspace. Operators can easily operate it without worrying about space constraints. Meanwhile, indicator lights and control buttons for showing the opening and closing status are mounted solely on the vertically opening door 2, with corresponding openings through which power supply lines pass. This allows operators to directly install the equipment onto the mounting bracket 4 inside the main body 1 via the openings. The wires are organized through the vertical cable tray 51 and the opening door cable tray 52, then pass through the openings to connect with the components on the vertically opening door 2. The entire process is simple and efficient, greatly improving installation efficiency.
[0027] The lateral opening door 3, capable of opening and closing horizontally, is hinged to the main body 1. The lateral opening door 3 is a standardized cabinet door, designed for personnel to install various switching devices within the switch cabinet, thus eliminating the need for customization of internal components. For personnel, the indicator lights on the vertical opening door 2 provide a clear view of the switch's open / closed status during daily use and maintenance. Inspections or maintenance of the switch cabinet's interior are conducted solely through the lateral opening door 3, significantly improving work efficiency and operational accuracy. Customization is limited to the design and fabrication of the vertical opening door 2, greatly reducing customization costs and shortening the overall production cycle of the switch cabinet.
[0028] Preferably, a limiting mechanism 6 is fixedly connected between the vertical opening / closing door 2 and the inner wall of the main body 1. The limiting mechanism 6 can limit the rotation angle of the vertical opening / closing door 2. On the one hand, it can protect the vertical opening / closing door 2 from damage to the hinge due to excessive rotation caused by external force when it is opened. On the other hand, it can provide a stable platform when the vertical opening / closing door 2 is opened, allowing for the installation or maintenance of components such as the indicator lights for the opening / closing status and the control buttons on the vertical opening / closing door 2. Specifically, the limiting mechanism 6 includes a positioning seat 61 installed on the inner wall of the main body 1. A slide rail seat 610 is installed on the positioning seat 61. An arc-shaped slide bar 621 is slidably connected inside the slide rail seat 610. A connecting seat 62 and a limiting seat 622 are respectively installed at both ends of the arc-shaped slide bar 621. The connecting seat 62 is fixedly connected to the vertical opening / closing door 2. Specifically, the arc-shaped slide bar 621 is an arc-shaped structure with the hinge point of the vertical opening and closing door 2 as the center. When the vertical opening and closing door 2 is opened and closed, the arc-shaped slide bar 621 can slide inside the slide rail seat 610. When the vertical opening and closing door 2 is opened and closed to a specified angle, the limit seat can abut against the slide rail seat 622, thereby preventing the vertical opening and closing door 2 from opening and closing further.
[0029] Preferably, the mounting frame 4 includes vertical frames 40 installed on opposite sides of the inner wall of the main body 1. A first horizontal frame 41, a second horizontal frame 42, a third horizontal frame 43, and a fourth horizontal frame 44 are sequentially installed between the vertical frames 40 from top to bottom. The first horizontal frame 41 and the second horizontal frame 42 cooperate to install equipment such as the main closing switch, while the third horizontal frame 43 and the fourth horizontal frame 44 cooperate to install equipment such as the opening and closing switch. Cables can pass through the space between the second horizontal frame 42 and the third horizontal frame 43, guiding the wires to the opening and closing door cable tray 52, where the wires are managed and connected to components such as indicator lights on the vertical opening and closing door 2.
[0030] Preferably, the bottom and top of the main body 1 are respectively provided with an air inlet 101 and a top air outlet 102. Filters and fans can be installed on the air inlet 101 and the top air outlet 102 for ventilation and heat dissipation.
[0031] Preferably, the cable management trough 5 includes a base frame 501 and a side rail 502 fixedly connected to the base frame 501. The side rail 502 is provided with a plurality of side rail slots 503 evenly arranged laterally along the side rail 502. The wires can pass through the side rail slots 503, thereby realizing the connection between the wires and the nearest electrical components.
[0032] Preferably, the side panel 502 of the cable management channel 5 is fixedly connected with a snap-fit edge 504 for engaging with the cable management channel cover (not shown in the figure). The cable management channel cover can be closed on the top of the cable management channel 5, and the edge of the cable management channel cover is provided with a snap-fit groove that matches the snap-fit edge 504, so that the top of the cable management channel 5 can be closed, resulting in better cable management.
[0033] Normally, the opening and closing status of a circuit breaker (relay) is indicated by an indicator light. Some high-voltage switchgear is equipped with mechanical labels marked "open" or "closed," and there are more specific international standards for the color of the indicator light and its corresponding opening and closing status. The ability of indicator lights to indicate the opening and closing status of a circuit breaker is fundamental knowledge for those skilled in the art. This technical solution focuses on the design of the switchgear, specifically addressing the issues of high customization costs and long production cycles associated with customized switchgear. However, to prevent confusion due to incomplete or unclear circuit technical solutions, the following explanation explains why the indicator light can display the opening and closing status of the circuit breaker. It is important to note that the following explanation of why the indicator light can display the opening and closing status of the circuit breaker is merely one solution found in the industry, and not the only solution; furthermore, the following explanation is only used to explain this utility model and is not intended to limit this utility model.
[0034] Relays have main contacts that directly carry high voltage / current and cannot be directly monitored. Therefore, high-voltage circuit breakers on the market typically have auxiliary contacts that operate synchronously with the main contacts, transmitting status signals through a control circuit. This is a common setup in electrical systems, including high-voltage power distribution systems, building electrical systems, and most other applications. Thus, the indicator light circuit can be electrically connected to the auxiliary contacts of the circuit breaker (relay) through a low-voltage control circuit, avoiding direct contact with the high-voltage main circuit and ensuring safety. The wiring methods described above are all existing technologies. Specific wiring methods for different indicator lights, relays, and controllers should be consulted according to their respective technical manuals; all of these are existing technologies.
[0035] In summary, during actual use, staff can intuitively understand the opening and closing status of the switchgear through the indicator lights on the vertical opening door 2. The indicator lights are connected to the wires passing through the corresponding openings on the vertical opening door 2. The wires are organized through the opening door cable tray 52 and the vertical cable tray 51 to ensure neat and orderly wiring. When it is necessary to inspect or maintain the inside of the switchgear, staff only need to operate by opening and closing the side opening door 3. The side opening door 3 is a standardized cabinet door, eliminating the need for customization based on the components inside the switchgear, greatly reducing customization costs and production time. During equipment installation, workers can directly install the equipment onto the mounting bracket 4 inside the main body 1 through the opening. The first horizontal bracket 41 and the second horizontal bracket 42 are used to install equipment such as the main closing switch, while the third horizontal bracket 43 and the fourth horizontal bracket 44 are used to install equipment such as the opening and closing switches. Cables can pass through the second horizontal bracket 42 and the third horizontal bracket 43, guiding the wires to the opening and closing door cable tray 52. The wires are then managed in the opening and closing door cable tray 52 and connected to the indicator lights and other components on the vertical opening and closing door 2. The entire installation process is simple and efficient, greatly improving installation efficiency.
[0036] Furthermore, the limiting mechanism 6, which is fixedly connected between the vertical opening door 2 and the inner wall of the main body 1, can limit the rotation angle of the vertical opening door 2. On the one hand, it protects the vertical opening door 2 from damage to the hinge due to excessive rotation caused by external force when it is opened. On the other hand, it provides a stable platform when the vertical opening door 2 is open, facilitating the installation or maintenance of components such as the indicator lights for the opening and closing status and the control buttons on the vertical opening door 2. The side rails 502 of the cable tray 5 are evenly provided with several side rail slots 503, through which wires can pass and connect to nearby electrical components. At the same time, the side rails 502 of the cable tray 5 are fixedly connected with a snap-fit edge 504 for snapping with the cable tray cover, so that the top of the cable tray 5 is closed, resulting in better cable management. The air inlet 101 at the bottom and the top air outlet 102 at the top of the main body 1 can be fitted with filters and fans for ventilation and heat dissipation, ensuring that the equipment operates in a good environment.
[0037] Therefore, through reasonable design and layout, this device not only improves the operational efficiency and accuracy of staff, but also reduces customization costs, shortens production time, and provides great convenience for the use and maintenance of switchgear.
[0038] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
