Abstract
Description
Technical Field
[0001] This utility model specifically relates to an independent arc-extinguishing cabinet with quick replacement of parts after an accident. Background Technology
[0002] An arc-extinguishing switchgear is an electrical device in which external power lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch circuit is configured according to its needs. Examples include instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switchgear, and are equipped with high-voltage busbars, such as in power plants. Some also have underfrequency load shearing to protect the main equipment.
[0003] Currently, when minor accidents such as short circuits occur in the internal electrical components of independently used arc extinguishing cabinets, it is inconvenient for staff to replace the electrical components because the circuit boards are fixed inside the cabinet, which affects the overall usability and reduces the effectiveness of use. Utility Model Content
[0004] The purpose of this invention is to provide an independent arc-extinguishing cabinet with quick replacement of parts after an accident, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an independent arc-extinguishing cabinet with quick replacement of parts after an accident, comprising a cabinet body, a cabinet door, a rotating assembly, a support plate, and a pull-out assembly. The cabinet door is mounted on the cabinet body via the rotating assembly, the support plate is installed inside the cabinet body, and a plurality of electrical components are disposed on the surface of the support plate. The support plate is pulled out from inside the cabinet body via the pull-out assembly to realize the replacement of the electrical components.
[0006] Preferably, the pull-out assembly includes fixing blocks disposed on the left and right sides of the cabinet body, and the two fixing blocks are provided with slide rails on opposite sides.
[0007] Preferably, a movable column is provided inside the slide rail, and the end of the movable column away from the slide rail is connected to the support plate.
[0008] Preferably, a through hole is provided on the upper surface of the movable column, and a spring is provided in the through hole. The end of the spring away from the through hole is connected to a limit head.
[0009] Preferably, handles are provided on both the upper and lower sides of the surface of the support plate.
[0010] Preferably, the fixing block has a limiting hole on its upper surface facing the cabinet door, and the limiting hole is connected to the slide rail.
[0011] Preferably, the rotating assembly includes a rotating shaft disposed on the upper and lower sides of the cabinet body, a rotating plate disposed on the rotating shaft, and the cabinet door is installed between the two rotating plates.
[0012] The technical effects and advantages of this utility model are as follows: This independent arc-extinguishing cabinet with quick replacement of parts after an accident allows for easy maintenance and replacement of electrical components on the surface of the support plate after a short circuit. When the electrical components on the support plate surface experience an accident, the operator can pull the handle to slide the moving column within the slide rail, allowing the support plate to be pulled out to the cabinet door. This facilitates the repair and replacement of electrical components on the support plate surface. The overall structure is simple and easy to use. When the moving column moves to the limiting hole, the spring deforms, and the limiting head loses its contact with the inner wall of the slide rail. The spring then acts on the limiting head, pushing it out of the slide rail and inserting it into the limiting hole, thus fixing the support plate and improving its stability during the replacement of electrical components.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] To facilitate the replacement of electrical components inside cabinet 1, please refer to... Figure 1 , Figure 2 and Figure 3As shown, the system includes a cabinet body 1, a cabinet door 2, a rotating assembly, a support plate 3, and a pull-out assembly. The cabinet door 2 is mounted on the cabinet body 1 via the rotating assembly. The support plate 3 is installed inside the cabinet body 1, and several electrical components are disposed on the surface of the support plate 3. The support plate 3 is pulled out from inside the cabinet body 1 via the pull-out assembly to replace the electrical components. When an electrical component on the surface of the support plate 3 experiences a short circuit, the operator can pull the handle 9 to slide the moving column 6 within the slide rail 5, thus pulling the support plate 3 to the cabinet door 2. This allows the operator to repair and replace the electrical components on the surface of the support plate 3. The overall structure is simple and easy to use. When the moving column 6 moves to the limiting hole 10, the spring 7 deforms, and the limiting head 8 loses its contact with the inner wall of the slide rail 5. The spring 7 then reacts to the limiting head 8, pushing the limiting head 8 out of the slide rail 5 and inserting it into the limiting hole 10, thus fixing the support plate 3.
[0020] To improve the stability of the support plate 3 when replacing electrical components, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the pull-out assembly includes fixed blocks 4 on the left and right sides inside the cabinet 1. Slide rails 5 are formed on opposite sides of the two fixed blocks 4. A movable column 6 is installed within the slide rails 5. The end of the movable column 6 away from the slide rail 5 is connected to a support plate 3. By sliding the movable column 6 along the length of the slide rail 5, the support plate 3 can be moved, allowing it to move from inside the cabinet 1 to the cabinet door 2, facilitating maintenance and inspection of the circuit structure and electrical components on the surface of the support plate 3. A through hole is formed on the upper surface of the movable column 6, and a spring 7 is installed within the through hole. A limit head 8 is connected to the end of the spring 7 away from the through hole. The inner wall of the slide rail 5 presses against the limit head 8, keeping the spring 7 in a compressed state. Handles 9 are provided on both the upper and lower sides of the support plate 3. Pulling the handles 9 allows the support plate 3 to be moved, improving convenience. The fixing block 4 has a limiting hole 10 on its upper surface facing the cabinet door 2. The limiting hole 10 is connected to the slide rail 5. When the limiting head 8 moves to the limiting hole 10, the limiting head 8 loses the compression of the inner wall of the slide rail 5, the spring 7 deforms, and the limiting head 8 pops out, allowing it to insert into the limiting hole 10, thus fixing the moving column 6 and subsequently the support plate 3. This facilitates the replacement and maintenance of electrical components by the staff. After maintenance, pressing the limiting head 8 compresses the spring 7, allowing the limiting head 8 to re-enter the slide rail 5, so that the support plate 3 can be pushed back into the cabinet 1. It should be noted that the cabinet 1 is in a horizontal state, so the support plate 3 remains fixed without external pulling force. The rotating assembly includes a rotating shaft 11 disposed on the upper and lower sides inside the cabinet 1. A rotating plate 12 is disposed on the rotating shaft 11. The cabinet door 2 is installed between the two rotating plates 12. The rotating shaft 11 drives the rotating plate 12 to rotate, thereby driving the cabinet door 2 to rotate.
[0021] In use, when the electrical components on the surface of the support plate 3 experience a short circuit, the operator can first pull the handle 9 to slide the moving column 6 within the slide rail 5, thus pulling the support plate 3 to the cabinet door 2. This allows the operator to repair and replace the electrical components on the surface of the support plate 3. The overall structure is simple and easy to use. When the moving column 6 moves to the limiting hole 10, the spring 7 deforms, and the limiting head 8 loses its contact with the inner wall of the slide rail 5. The spring 7 then acts on the limiting head 8, pushing the limiting head 8 out of the slide rail 5 and inserting it into the limiting hole 10, thus fixing the support plate 3.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
