Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a circuit breaker with a split-type lightweight upper support. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. A circuit breaker generally consists of a contact system, an arc-extinguishing system, an operating mechanism, a trip unit, and a casing. During a short circuit, the magnetic field generated by the large current overcomes the counterforce spring, causing the trip unit to pull the operating mechanism, and the switch trips instantaneously. During an overload, the current increases, heat generation intensifies, and the bimetallic strip deforms to a certain extent, pushing the mechanism to actuate and causing the circuit breaker to trip.

[0003] Circuit breakers generate heat during operation, especially when carrying large currents. If the distance between the circuit breaker and its mounting surface is too close, heat dissipation will be restricted, causing the circuit breaker temperature to rise and affecting its performance and lifespan. Therefore, maintaining a certain distance between the circuit breaker and its mounting surface helps with heat dissipation and ensures normal operation. Typically, during installation, a slide rail is used to hold each circuit breaker in place. When one circuit breaker needs maintenance or replacement, the entire slide rail must be removed for inspection or replacement. This process is difficult, increasing the time cost of maintenance or replacement and affecting the timely restoration of the power system. Utility Model Content

[0004] The purpose of this invention is to provide a circuit breaker with a split-type lightweight upper support to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circuit breaker with a split-type lightweight upper support includes:

[0007] The circuit breaker body has a mounting plate on one side, and an upper support and a lower support are fixedly mounted on the mounting plate.

[0008] An arc-shaped block is fixedly mounted on an upper support, and the upper part of the circuit breaker body is connected to the arc-shaped block and the upper support.

[0009] A slider is slidably disposed at the lower part of the circuit breaker body, and the circuit breaker body is engaged with the lower support through the slider.

[0010] Preferably, the circuit breaker body is symmetrically arranged on one side of the mounting plate, the upper support is arranged on the upper part of the mounting plate, the lower support is arranged on the lower part of the mounting plate, and the arc-shaped block extends upward in an arc shape from the middle of the upper support.

[0011] Preferably, a number of locking blocks are horizontally fixed on the upper part of the circuit breaker body, and the circuit breaker body is fastened to the upper support by the locking blocks.

[0012] Preferably, each circuit breaker body has a mounting groove at its lower part, and the mounting groove is slidably connected to the slider.

[0013] Preferably, each slider has a through slot, and each slider has a fixing block symmetrically arranged.

[0014] Preferably, each of the mounting slots is symmetrically provided with grooves, each of the grooves is provided with an elastic element, and each of the fixing blocks slides within the groove.

[0015] Preferably, a second fixing block is symmetrically fixed on the lower support, and the side of the second fixing block away from the lower support is an inclined surface, and the length of the second fixing block is adapted to the width of the slot.

[0016] Preferably, a limiting groove is provided on both the front and back sides of the fixing block 2. The limiting groove is divided into a cylindrical section and a square section. An elastic element 2 is fixedly provided in the cylindrical section of the limiting groove.

[0017] Preferably, each of the limiting grooves is provided with a limiting block, which is divided into a cylindrical segment and a square segment. The cylindrical segment and the square segment of the limiting block slide within the cylindrical segment and the square segment of the limiting groove, respectively.

[0018] Preferably, the side of the limiting block away from the slider is set as an inclined surface.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The use of arc-shaped blocks and fixing blocks allows the circuit breaker body to be quickly installed on the upper and lower supports, simplifying the installation process and reducing installation time. This is particularly important for power systems requiring rapid deployment and commissioning, as it can shorten power outage time and improve power supply reliability.

[0021] The circuit breaker body is prevented from shifting left or right, or up or down, by the mutual restraint between the slider and the slot, as well as between the limiting block and the fixed block, thus preventing accidental detachment and reducing the risk of equipment damage and electrical faults. The robust support and limiting design makes the circuit breaker body less prone to displacement or detachment during maintenance. This simplifies the maintenance process and reduces maintenance costs.

[0022] The slider in the mounting slot, in conjunction with the elastic element, allows it to slide up and down during installation. This provides or removes limits for the installation or removal of the slider, simplifying the operation process, improving installation efficiency, and enhancing structural stability.

[0023] The inclined surface design of the second fixing block allows the slider to gradually press into the slot on the slider during the snap-fit ​​process at the bottom of the circuit breaker body, thus securing the bottom of the circuit breaker. This simplifies the installation process, reduces the precision requirements, and makes installation more convenient and faster. Once the slider is engaged in the slot, a secure connection is formed between the second fixing block and the slider, fixing the bottom of the circuit breaker body. This fixing effect prevents the circuit breaker body from swaying left and right during installation, improving the overall structural stability. Attached Figure Description

The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0035] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0036] Please see Figures 1-6 A circuit breaker with a split-type lightweight upper support includes: a circuit breaker body 1, which is the core component of the circuit breaker and is responsible for breaking and closing the circuit. A mounting plate 2 is provided on one side of the circuit breaker body 1, and an upper support 3 and a lower support 12 are fixedly mounted on the mounting plate 2. The upper support 3 and the lower support 12 adopt a split structure for easy installation and disassembly. The upper support 3 adopts a lightweight design, such as using lightweight materials like aluminum to support heat dissipation components, reducing the overall weight of the circuit breaker. The lightweight design helps reduce the transportation and installation costs of the circuit breaker, while improving its operational stability and reliability.

[0037] A circuit breaker with a split lightweight upper support also includes: an arc block 5, which is fixedly mounted on the upper support 3. The upper part of the circuit breaker body 1 is connected to the arc block 5 and the upper support 3. Through the connection with the arc block 5, the upper part of the circuit breaker body 1 is more stably supported.

[0038] A circuit breaker with a split lightweight upper support further includes a slider 7, which is slidably disposed at the lower part of the circuit breaker body 1. The circuit breaker body 1 is interlocked with the lower support 12 by the slider 7. Through the interlocking of the slider 7 and the lower support 12, the circuit breaker body 1 is stably supported, and it is also convenient to disassemble and replace when needed.

[0039] The circuit breaker body 1 is symmetrically arranged on one side of the mounting plate 2. The upper support 3 is located on the upper part of the mounting plate 2, and the lower support 12 is located on the lower part of the mounting plate 2. The arc-shaped block 5 extends upward in an arc shape from the middle of the upper support 3. Several locking blocks 4 are horizontally fixed on the upper part of the circuit breaker body 1. The circuit breaker body 1 is snapped onto the upper support 3 by the locking blocks 4. The locking blocks 4 on the circuit breaker body 1 are directly snapped into the arc-shaped block 5, and the upper part of the circuit breaker body 1 is fixed. The operation is convenient and simple. The snapping method between the locking blocks 4 and the arc-shaped block 5 simplifies the installation process, eliminating the need for complex bolt connections or other fasteners, thereby reducing installation time.

[0040] Furthermore, each circuit breaker body 1 has a mounting groove 6 at its lower part, and the mounting groove 6 is slidably connected to the slider 7. Each slider 7 has a through-hole groove 9, and each slider 7 has a symmetrically arranged fixing block 8. Each mounting groove 6 has a symmetrically arranged recess 10, and each recess 10 has an elastic element 11, in which the fixing block 8 slides. The slider 7 in the mounting groove 6, in conjunction with the elastic element 11, allows it to slide up and down during installation, providing or releasing limits for the installation or removal of the slider 7, simplifying the operation process, improving installation efficiency, and enhancing structural stability.

[0041] It should be noted that fixing blocks 13 are symmetrically fixed on the lower support 12. The side of fixing blocks 13 away from the lower support 12 is an inclined surface. The length of each fixing block 13 is adapted to the width of the slot 9. The inclined surface design allows the slider 7 to gradually press into the slot 9 on the slider 7 during the snap-fit ​​process of the lower part of the circuit breaker body 1, thus fixing the lower part of the circuit breaker and preventing it from swaying left and right. The inclined surface design also allows the slider 7 to act as a guide device, gradually guiding it into the slot 9 above during the snap-fit ​​process of the lower part of the circuit breaker body 1. This guiding effect simplifies the installation process, reduces the requirements for installation accuracy, and makes installation more convenient and faster. Once the slider 7 is snapped into the slot 9, a firm connection is formed between the fixing blocks 13 and the slider 7, thereby fixing the lower part of the circuit breaker body 1. This fixing effect prevents the circuit breaker body 1 from swaying left and right during installation, improving the overall structural stability.

[0042] Furthermore, limiting grooves are formed on both sides of the fixed block two. These limiting grooves are divided into cylindrical and square segments, and elastic elements are fixedly installed within the cylindrical segments of each limiting groove. Limiting blocks, also divided into cylindrical and square segments, are installed within each limiting groove, and these segments slide within the respective cylindrical and square segments of the limiting groove. The side of the limiting block furthest from the slider is designed as an inclined surface. When the lower fixing block 2 of the circuit breaker presses against the slider, the limiting block is pressed under the constraint of the slot on the slider. The elastic element 2 is compressed and retracts, and the limiting block retracts into the limiting groove. When the limiting block is released from compression, the elastic element 2 causes the limiting block to return to its initial position. The plane of the limiting block limits the bottom of the circuit breaker. Through rapid left-right and up-down limiting, the circuit breaker body is stably installed on the upper and lower supports. When it is necessary to disassemble the circuit breaker body, the limiting block is pressed, causing the limiting block to retract into the limiting groove again. Then, the lower part of the circuit breaker body is rotated. Due to the setting of the elastic element 1, the slider can move up and down, thereby disengaging the lower part of the circuit breaker body from the fixing block 2. At this time, the operator can quickly disassemble the circuit breaker body for maintenance or replacement.
