Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a circuit breaker truck compartment and switchgear. Background Technology

[0002] In switchgear, especially 35kV switchgear, circuit breaker trolleys are often floor-mounted, allowing for easy installation, disassembly, and maintenance. However, the trolleys are heavy, and during maintenance, they need to be moved from inside the switchgear to the maintenance access area. Due to their weight and size, the trolleys are prone to tilting or jamming during movement, increasing safety hazards for operators. Especially without specialized tools, the movement process is cumbersome and difficult to maintain stability, causing significant inconvenience to maintenance work.

[0003] Currently, existing switchgear track designs generally lack effective extension and fixing structures, failing to meet the requirements for smooth and precise handling and positioning of the trolley. Traditional track designs can only ensure simple movement of the trolley within the cabinet, lacking support and buffer structures for the trolley after it is removed from the cabinet. This makes it difficult to ensure smooth movement of the circuit breaker trolley during removal from the cabinet, and it is prone to deviation, thus affecting the efficiency and safety of maintenance operations. Utility Model Content

[0004] The purpose of this application is to provide a circuit breaker truck compartment and switch cabinet, which aims to solve the technical problem that it is difficult to ensure smooth movement of existing circuit breaker trucks during the removal of them from the cabinet.

[0005] To achieve the above objectives, this application proposes a circuit breaker truck compartment, the circuit breaker truck compartment comprising:

[0008] In one embodiment, there are two booster rails, which extend along the direction of the circuit breaker trolley moving in or out. The distance between the two booster rails decreases from the connection between the support and the rail plate toward the maintenance area and is distributed in a V-shape.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the application 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 application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0026] The embodiments described in this application are only some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application.

[0027] In switchgear, especially 35kV switchgear, circuit breaker trolleys are often floor-mounted, allowing for easy installation, disassembly, and maintenance. However, the trolleys are heavy, and during maintenance, they need to be moved from inside the switchgear to the maintenance access area. Due to their weight and size, the trolleys are prone to tilting or jamming during movement, increasing safety hazards for operators. Especially without specialized tools, the movement process is cumbersome and difficult to maintain stability, causing significant inconvenience to maintenance work.

[0028] Currently, existing switchgear track designs generally lack effective extension and fixing structures, failing to meet the requirements for smooth and precise handling and positioning of the trolley. Traditional track designs can only ensure simple movement of the trolley within the cabinet, lacking support and buffer structures for the trolley after it is removed from the cabinet. This makes it difficult to ensure smooth movement of the circuit breaker trolley during removal from the cabinet, and it is prone to deviation, thus affecting the efficiency and safety of maintenance operations.

[0029] To address the aforementioned technical problems, this application proposes a circuit breaker truck compartment. Please refer to [link / reference needed]. Figure 1 and Figure 2 In one embodiment of this application, the circuit breaker truck compartment includes a compartment body 100, a track plate 200, a truck track 300, and a boosting mechanism 400. The track plate 200 is installed inside the compartment body 100, and the truck track 300 is fixed to the track plate 200. The boosting mechanism 400 includes a support plate 410 and a boosting track 420. The support plate 410 includes a support portion 411 and an inclined surface 412 disposed on the support portion 411. The support portion 411 is detachably connected to the track plate 200. The detachable connection between the support portion 411 and the track plate 200 can be a bolt connection or a snap-fit ​​connection, which is not limited here. One end of the inclined surface 412 is located at the connection between the support part 411 and the track plate 200. The other end of the inclined surface 412 extends to the maintenance area along the direction of the circuit breaker trolley moving in or out and forms a boosting ramp. The boosting track 420 is fixed to the inclined surface 412 and connected to the trolley track 300, which enables the circuit breaker trolley moving in or out of the trolley compartment body 100 to pass smoothly and achieve buffering.

[0030] The technical solution of this application adopts a detachable connection between the support part 411 and the track plate 200. One end of the inclined surface 412 is located at the connection between the support part 411 and the track plate 200, and the other end of the inclined surface 412 extends to the maintenance area along the direction of the circuit breaker trolley moving in or out and forms a boosting ramp. The boosting track 420 is fixed to the inclined surface 412 and connected to the trolley track 300. This allows the circuit breaker trolley moving in or out of the trolley compartment body 100 to transition smoothly and achieve buffering. This ensures that the trolley can still move smoothly and accurately after being removed from the switch cabinet and is easy to position in the maintenance channel, thereby improving the operational safety and maintenance efficiency of the trolley.

[0031] Please see Figure 1 and Figure 2In one embodiment, there are two booster rails 420, which extend along the direction of the circuit breaker trolley's entry or exit. The distance between the two booster rails 420 decreases from the connection between the support part 411 and the track plate 200 towards the maintenance area and is distributed in a V-shape. This embodiment, by setting two booster rails 420 in a V-shape, effectively guides the circuit breaker trolley to remain stable during entry or exit, reducing friction and improving operational smoothness and stability. As the distance between the two rails gradually decreases, it better adapts to the guiding needs of the trolley, preventing deviation or jamming during movement, thus improving the reliability and safety of the equipment.

[0032] Please see Figure 2 In one embodiment, the toe of the ramp is θ, where 2° ≤ θ ≤ 3°. Specifically, θ can be either 2° or 3°, and is not limited here. This embodiment, by setting the toe angle of the ramp between 2° and 3°, can smoothly guide the circuit breaker trolley to move along the track, ensuring that the trolley is not subjected to excessive impact force during entry and exit, reducing wear and tear on the equipment, and improving operational stability and safety. This angle range optimizes the boosting effect, avoiding both excessive friction caused by an overly steep ramp and insufficient boosting effect caused by an overly gentle ramp, making the trolley operation smoother and more efficient, further improving the overall performance and service life of the equipment.

[0033] Please see Figures 2 to 4 In one embodiment, the support 411 includes a support body 4111 and a fastener 4112 fixed to the support body 4111. An inclined surface 412 is disposed on the support body 4111. The track plate 200 includes a plate body 210 and mounting holes 220. The fastener 4112 is detachably engaged with the mounting holes 220. This embodiment achieves stability and convenient disassembly and installation of the support 411, facilitating subsequent maintenance and replacement. The inclined surface 412 effectively improves the stress distribution, making the structure more robust and adaptable, capable of handling different working environments. The plate body 210 of the track plate 200 is combined with the mounting holes 220, and the fastener 4112 is detachably engaged with the mounting holes 220, enhancing the adjustability and flexibility of the overall structure, simplifying the installation and disassembly process, and contributing to improved production efficiency and ease of use.

[0034] Please see Figure 2 and Figure 4In one embodiment, the number of fixing members 4112 is at least two, and the at least two fixing members 4112 are spaced apart along a direction perpendicular to the direction in which the circuit breaker trolley moves in or out. The number of mounting holes 220 corresponds one-to-one with the number of fixing members 4112, and the at least two fixing members 4112 are detachably engaged with the corresponding mounting holes 220. This embodiment, by providing at least two fixing members 4112 and distributing them at intervals along a direction perpendicular to the direction in which the circuit breaker trolley moves in or out, ensures greater stability of the support 411, avoids uneven local stress caused by a single fixing member 4112, and improves the compressive strength and overall stability of the structure. The one-to-one correspondence between the fixing members 4112 and the mounting holes 220, and their detachable engagement, enhances the maintainability and convenience of the components, facilitating later adjustments and replacements. This design not only optimizes the installation process but also improves the reliability and safety of the equipment, helping to ensure stable operation of the equipment during long-term use.

[0035] Please see Figure 2 and Figure 4 In one embodiment, the fixing element 4112 is a hook, which is detachably engaged with the mounting hole 220. Specifically, inserting the hook into the mounting hole 220 temporarily fixes the support plate 410 to the track plate 200, thereby connecting the booster track 420 to the handcart track 300; pulling the hook out of the mounting hole 220 separates the support plate 410 from the track plate 200, facilitating the storage of the booster mechanism 400. This embodiment simplifies the installation and disassembly process by using a hook as the fixing element 4112 and detachably engaging with the mounting hole 220, improving the system's flexibility and maintainability. The hook design allows the fixing element 4112 to be more easily connected and separated from the mounting hole 220, ensuring a stable fixing effect while allowing for quick disassembly when needed, reducing operation time and labor intensity. The detachable engagement of the hook with the mounting hole 220 increases the system's adjustability and adaptability, especially when the equipment requires regular maintenance or component replacement, greatly improving work efficiency and safety. In addition, hook designs typically have strong load-bearing capacity and good shock resistance, ensuring sufficient stability during equipment operation.

[0036] Please see Figure 2 and Figure 4In one embodiment, the fastener 4112 is a bolt, which is detachably engaged with the mounting hole 220. Specifically, one end of the bolt is fixedly connected to the support body 4111, and the other end passes through the mounting hole 220 and is secured with a nut. This embodiment provides a more robust and reliable connection by using a bolt as the fastener 4112 and detachably engaging with the mounting hole 220. The bolt provides high-strength fastening while ensuring connection stability, avoiding loosening due to vibration or external forces. Due to the detachable engagement design of the bolt with the mounting hole 220, users can easily install, adjust, repair, and replace components. The removal and reinstallation of the bolt are also relatively simple and ensure the stability of the connection during use.

[0037] Please see Figure 2 In one embodiment, the support body 4111 adopts a hollow structure. This hollow structure design effectively reduces the weight of the support body 4111, improving the overall portability of the device. Simultaneously, the reasonable distribution of holes maintains sufficient load-bearing capacity and stability, ensuring the reliability of the device under high loads. Furthermore, the hollow structure enhances airflow and improves heat dissipation, helping to extend the device's service life. By reducing material usage, this embodiment also helps to reduce manufacturing costs.

[0038] Please see Figure 2 In one embodiment, the support body 4111 is constructed of sheet metal. This embodiment, by using sheet metal as the primary material for the support body 4111, provides high strength and durability, while also possessing good machinability, enabling efficient mass production. Sheet metal is lightweight, effectively reducing the overall burden on the equipment and improving its mobility and convenience. Furthermore, the corrosion resistance and oxidation resistance of sheet metal ensure the long-term stability and reliability of the equipment in various environments. Through proper forming and processing, the support body 4111 can maintain high-precision dimensions and shape, ensuring the stability and service life of the equipment.

[0039] In addition, to achieve the above objectives, this application also proposes a switch cabinet, which includes a circuit breaker truck compartment. The specific structure of the circuit breaker truck compartment is as described in the above embodiments. Since this switch cabinet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0040] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this application and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this application should be included within the protection scope of this application.
