Description

Technical Field

[0001] This utility model relates to the field of outdoor circuit breaker technology, specifically to an outdoor circuit breaker. Background Technology

[0002] In today's power system, outdoor circuit breakers are key equipment for ensuring a stable power supply, and their importance is self-evident. With the rapid development of the social economy, both the continuous expansion of urban power grids and the upgrading and transformation of rural power grids have placed higher demands on the reliability, stability and intelligence level of power supply.

[0003] In harsh natural environments, the performance of aging outdoor circuit breakers gradually deteriorates, making it difficult to guarantee a stable power supply. Frequent power outages in rural areas not only affect farmers' daily lives but also hinder the development of rural industries. Therefore, rural power grids urgently need a type of outdoor circuit breaker that can adapt to complex environments, requires little or no maintenance, and is highly reliable, in order to improve power supply quality and further promote rural economic development.

[0004] The spatial conditions for outdoor installation vary significantly. Urban substations often face the problem of limited space, requiring circuit breakers to be densely arranged to fit the confined area. In contrast, rural power grid outdoor installation points are often located in open terrain, but the lines are scattered, requiring the spacing of circuit breakers to be flexibly set according to the line length. Traditional fixed installation methods are difficult to accommodate these diverse spatial requirements, often resulting in line crossing interference due to excessively close spacing or cable waste due to excessively large spacing. As the power load increases, existing lines may need to have additional circuit breakers or phase layout adjustments. However, the fixed spacing of traditional equipment cannot adapt to the new line connection distances, often requiring the replacement of the entire installation base or the re-pouring of concrete foundations. This not only increases the renovation period and cost but may also lead to longer power outage times and affect power supply reliability.

[0005] Therefore, an outdoor circuit breaker is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] An outdoor circuit breaker includes a stabilizing platform 1, a support column 2 fixedly connected to the bottom of the stabilizing platform 1, an mounting plate 3 provided on the top of the stabilizing platform 1, a circuit breaker body 4 fixedly connected to the top of the mounting plate 3, an electrical cabinet 5 provided at the bottom of the stabilizing platform 1, and a spacing adjustment mechanism 6 provided inside the stabilizing platform 1.

[0027] The spacing adjustment mechanism 6 includes a moving groove 61, a slide rail 62 fixedly connected inside the moving groove 61, a slider 63 slidably connected to the outside of the slide rail 62, a sliding hole 64 slidably connected inside the slider 63, and a connecting rod 65 fixedly connected to the top of the slider 63.

[0028] It should be noted that: the support columns 2 are symmetrically distributed at the bottom of the stable platform 1, the mounting plate 3 and the circuit breaker body 4 are evenly distributed above the stable platform 1, the two ends of the slide rail 62 are fixedly connected to the inner walls of the two sides of the moving groove 61, the slider 63 is slidably connected inside the moving groove 61, and the slider 63 is slidably connected to the outside of the slide rail 62 through the sliding hole 64 inside it, and the top of the connecting rod 65 is fixedly connected to the bottom of the mounting plate 3.

[0029] Furthermore, the stable platform 1 is not a single planar structure. The depth of the reserved moving groove 61 and the height of the slide rail 62 are adapted to each other. The width of the groove 61 is slightly larger than the thickness of the slider 63, which ensures that the slider 63 can slide freely, while restricting its lateral displacement through the groove wall. The extension design of the support column 2 is also noteworthy. Adjustable anchor bolts are added to its bottom. By rotating the bolts, the flatness error of the outdoor ground is compensated. Combined with the symmetrical layout, the horizontal stability of the stable platform 1 is further enhanced.

[0030] Specifically: The extended function of the spacing adjustment mechanism 6 is reflected in the multi-group linkage design. Since the mounting plate 3 and the circuit breaker body 4 are evenly distributed, the corresponding sliders 63 and connecting rods 65 are also arranged at equal intervals. Each slider 63 can move independently along the slide rail 62, which supports the individual adjustment of a single circuit breaker body 4 and can also realize the overall displacement of multiple sets of equipment through synchronous pushing. In addition, the limit block design at both ends of the slide rail 62 can prevent the sliders 63 from sliding out of the moving groove 61.

[0031] Meanwhile, the top of the electrical cabinet 5 is fixed to the bottom of the stable platform 1 with bolts, and a rubber sealing gasket is installed at the connection to prevent rainwater from seeping in. The side of the electrical cabinet 5 is reserved with heat dissipation holes, which form an air convection channel with the ventilation gap at the bottom of the stable platform 1 to dissipate heat for the internal electrical components. At the same time, the cabinet door of the electrical cabinet 5 adopts a magnetic closing design, combined with waterproof rubber strips, which improves the sealing performance while ensuring quick opening and closing, and is suitable for outdoor dusty and rainy environments.

[0032] As a further implementation of this solution, a convenient installation mechanism 7 is provided on the outer side of the mounting plate 3. The convenient installation mechanism 7 includes an L-shaped plate 71, a threaded tube 72 is fixedly connected to the outer side of the L-shaped plate 71, a screw 73 is threadedly connected to the inside of the threaded tube 72, a rotating handle 74 is fixedly connected to the outer side of the screw 73, and a threaded hole 75 is opened in the side wall of the stable platform 1.

[0033] It should be noted that: L-shaped plates 71 are fixed and symmetrically distributed on the outside of mounting plate 3, and the bottom of L-shaped plates 71 is located on the outside of stable platform 1. Screws 73 pass through the inside of L-shaped plates 71. The number of screws 73 and threaded holes 75 are the same, and the two are compatible.

[0034] Furthermore, the structural extension of the convenient installation mechanism 7 focuses on balancing ease of operation and connection strength. The L-shaped plate 71 adopts a right-angle bending process, and its welding point with the mounting plate 3 is fully welded to ensure load-bearing strength. The vertical fixing angle error between the threaded tube 72 and the L-shaped plate 71 is controlled within ±1° to ensure the coaxiality of the screw 73 when screwed in. The extended design of the rotating handle 74 includes anti-slip texture and a force-saving lever structure. The diamond texture on the outside of the handle increases friction to prevent slippage during operation in rainy weather. The handle length is designed to be 5 times the diameter of the screw 73, which reduces the tightening force through the lever principle and improves ease of operation.

[0035] Workflow: In terms of overall structural support, the stable platform 1 serves as the core load-bearing component. Its bottom is fixed to the outdoor foundation surface by symmetrically distributed support columns 2, forming a stable mounting base. The circuit breaker body 4 is mounted on top of the stable platform 1 by mounting plate 3. The electrical cabinet 5 at the bottom integrates the line connection and control components, forming an integrated structure of "support-load-function", providing a basic framework for the circuit breaker's power switching and protection functions.

[0036] When it is necessary to adjust the spacing between the circuit breaker bodies 4, the operator can directly push the mounting plate 3. At this time, the connecting rod 65 fixed at the bottom of the mounting plate 3 drives the slider 63 to move synchronously. The slider 63 slides along the slide rail 62 in the moving groove 61 through the internal sliding hole 64. The two ends of the slide rail 62 are fixed to the inner wall of the moving groove 61 to ensure that the slider 63 moves stably in a straight line, thereby accurately adjusting the spacing between the mounting plate 3 and the circuit breaker body 4 above to adapt to different line connection requirements.

[0037] During installation, the mounting plate 3 is placed on top of the stable platform 1, with the symmetrically distributed L-shaped plates 71 on its outer side adhering to the side wall of the stable platform 1. At this time, the threaded tube 72 on the L-shaped plate 71 is aligned with the threaded hole 75 on the side wall of the stable platform 1. The operator rotates the rotating handle 74, causing the screw 73 to be screwed into the threaded hole 75 along the inside of the threaded tube 72. The self-locking property of the thread is used to fasten the L-shaped plate 71 to the stable platform 1, thereby completing the fixing of the mounting plate 3. To disassemble, the screw 73 can be loosened by rotating the rotating handle 74 in the opposite direction. This greatly simplifies the installation and disassembly process and improves maintenance efficiency.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
