Description

Technical Field

[0001] This utility model relates to the field of high-voltage circuit breaker installation technology, specifically a high-voltage circuit breaker that is easy to install. Background Technology

[0002] In the power transmission and distribution process, high-voltage circuit breakers, as core control and protection equipment, play a crucial role in cutting off or connecting high-voltage circuits and protecting lines and electrical equipment from overload, short circuit and other faults. Their installation scenarios are mostly concentrated in high locations such as outdoor utility poles and substation structures. The installation process must take into account equipment stability, operational safety and construction efficiency, which puts extremely high requirements on the rationality of the installation structure.

[0003] Traditional installation methods rely heavily on manual handling and multiple sets of bolts for fixing. Due to the large weight of the high-voltage circuit breaker and the limited outdoor working space, manual positioning is difficult. It requires multiple people to work together to complete the hoisting and alignment, and the bolt positions need to be repeatedly adjusted to ensure the equipment is level. This results in a complicated and time-consuming installation process, which greatly increases the labor intensity of construction workers and the risks of working at height.

[0004] Meanwhile, the existing installation structure has a simple fixing mechanism, with most circuit breakers connected to the base only by bottom bolts, lacking multi-dimensional limiting and reinforcement design.

[0005] According to the patent application published on the Internet, a high-voltage vacuum circuit breaker that is easy to install includes a "mounting base, upper support plate", etc., to facilitate installation.

[0006] Regarding the above description, the applicant believes the following issues exist:

[0007] This easy-to-install high-voltage vacuum circuit breaker utilizes a mounting base and upper support plate for installation. During operation, the circuit breaker operates by engaging a gear and a rack, which in turn moves the rack back and forth, allowing the mounting plate and circuit breaker body to be loosened and installed. However, the lack of a limiting or self-locking mechanism between the gear and rack means that after installation, various factors can cause loosening, affecting installation stability. Therefore, improvements to this circuit breaker are necessary. Utility Model Content

[0008] The purpose of this invention is to provide a high-voltage circuit breaker that is easy to install, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage circuit breaker that is easy to install, comprising a base, connecting shafts fixedly connected to the left and right sides of the top of the base, connecting seats slidably connected to the periphery of the connecting shafts, the connecting seats being disposed on the top of the base, a circuit breaker body being fixedly connected to the inner side of the connecting seats, first fixing mechanisms being disposed on the left and right sides of the circuit breaker body, a second fixing mechanism being disposed in front of the first fixing mechanisms, and fixing seats being fixedly connected to the front and rear sides of the base;

[0010] The first fixing mechanism includes a servo motor, which is fixedly connected to the left side of the base. A protective cover is slidably connected to the periphery of the servo motor. A threaded rod is fixedly connected to the right side of the servo motor. A movable seat is threadedly connected to the periphery of the threaded rod. A guide rod is slidably connected inside the movable seat. A limit frame is fixedly connected to the inner side of the movable seat. The limit frame is slidably connected to the periphery of the connecting shaft and the top of the connecting seat. An insertion rod is fixedly connected to the inner side of the limit frame and inserted into the inside of the connecting shaft. A protective plate is fixedly connected to the top of the limit frame and slidably connected to the top of the connecting shaft. A clamping plate is fixedly connected to the top of the protective plate and is located on the left side of the circuit breaker body. A protective box is slidably connected to the periphery of the movable seat.

[0011] Preferably, the protective cover is fixedly connected to the left side of the base, the threaded rod is rotatably connected to the inside of the base, and the bottom of the connecting seat is in contact with the top of the base, so that the servo motor can be protected by the protective cover.

[0012] Preferably, the movable seat is slidably connected to the inside of the base, the guide rod is fixedly connected to the inside of the base, and the movable seat, the limiting frame, the insert rod, the protective plate and the clamp are all located inside the protective box, so as to ensure the stability of the movable seat when it moves through the guide rod.

[0013] Preferably, the top of the inner side of the protective plate is in contact with the top of the connecting shaft, the right side of the clamping plate is in contact with the left side of the circuit breaker body, and an insulating pad is provided on the right side of the clamping plate to facilitate further fixation of the circuit breaker body through the clamping plate.

[0014] Preferably, the protective cover, servo motor, threaded rod, guide rod, moving seat, limiting frame, plug rod, protective plate, clamping plate and protective box are provided in two sets and symmetrically distributed on the left and right sides of the circuit breaker body. By setting two sets, the stability of the circuit breaker body during use can be further guaranteed.

[0015] Preferably, the second fixing mechanism includes a support arm, which is fixedly connected to the front and rear sides of the protective box. A slide rail is fixedly connected to the bottom of the support arm, and the slide rail is slidably connected to the top of the base. A fixed shaft is threaded inside the slide rail.

[0016] Preferably, the fixed shaft passes through the interior of the base, and the support arm, slide rail and fixed shaft are provided in two sets and symmetrically distributed on the front and rear sides of the two sets of protective boxes, so as to ensure the stability of the slide rail through the fixed shaft, thereby ensuring the stability of the protective box.

[0017] Compared with the prior art, this utility model provides a high-voltage circuit breaker that is easy to install and has the following advantages:

[0018] 1. This easy-to-install high-voltage circuit breaker, through its first fixing mechanism, allows for easy installation during use. First, the mounting base is fixed to an outdoor utility pole using external fixing equipment to ensure stability. Then, the circuit breaker body is hoisted to the top of the base using external hoisting equipment. The circuit breaker body then slides its connecting seat onto the outer periphery of the connecting shaft, ensuring initial stability. Next, a servo motor drives a movable seat, threadedly connected to the threaded rod, to slide within the base and around the guide rod. This movable seat then moves a limiting frame to the top of the connecting seat and the outer periphery of the connecting shaft, simultaneously inserting a plug rod into the connecting shaft. This limits the connection shaft's position and ensures the stability of the circuit breaker body. Finally, the limiting frame moves a protective plate to the top of the connecting shaft, causing the protective plate and clamp to contact the left side of the circuit breaker body, further securing the circuit breaker body and completing the installation process. The operation is convenient.

[0019] 2. This easy-to-install high-voltage circuit breaker utilizes a second fixing mechanism. When the circuit breaker body and connecting shaft are fixed and limited by clamps and insert rods, the circuit breaker body is installed. The support arm's bottom slide rail engages with the base, and the fixed shaft passes through the base's threaded fastener, limiting the protective box from the front and rear directions. The protective box slides to the periphery of the movable seat, ensuring its stability and limiting the movable seat. This prevents the threaded rod from rotating under external influences, causing the movable seat to loosen, affecting installation stability, and improving equipment operational reliability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-6This utility model provides a technical solution: a high-voltage circuit breaker that is easy to install, including a base 1, a connecting shaft 7 fixedly connected to the left and right sides of the top of the base 1, a connecting seat 6 slidably connected to the outer periphery of the connecting shaft 7, the connecting seat 6 being disposed on the top of the base 1, a circuit breaker body 3 being fixedly connected to the inner side of the connecting seat 6, a first fixing mechanism 4 being disposed on the left and right sides of the circuit breaker body 3, a second fixing mechanism 5 being disposed on the front side of the first fixing mechanism 4, and a fixing seat 2 being fixedly connected to the front and rear sides of the base 1.

[0033] The first fixing mechanism 4 includes a servo motor 42, which is fixedly connected to the left side of the base 1. A protective cover 41 is slidably connected to the periphery of the servo motor 42. A threaded rod 43 is fixedly connected to the right side of the servo motor 42. A movable seat 45 is threadedly connected to the periphery of the threaded rod 43. A guide rod 44 is slidably connected inside the movable seat 45. A limit frame 46 is fixedly connected to the inner side of the movable seat 45. The limit frame 46 is slidably connected to the periphery of the connecting shaft 7 and the top of the connecting seat 6. An insertion rod 47 is fixedly connected to the inner side of the limit frame 46 and is inserted into the inside of the connecting shaft 7. A protective plate 48 is fixedly connected to the top of the limit frame 46 and is slidably connected to the top of the connecting shaft 7. A clamping plate 49 is fixedly connected to the top of the protective plate 48 and is located on the left side of the circuit breaker body 3. A protective box 491 is slidably connected to the periphery of the movable seat 45.

[0034] The protective cover 41 is fixedly connected to the left side of the base 1, the threaded rod 43 is rotatably connected to the inside of the base 1, and the bottom of the connecting seat 6 is in contact with the top of the base 1, so that the servo motor 42 can be protected by the protective cover 41.

[0035] The movable seat 45 is slidably connected to the inside of the base 1, and the guide rod 44 is fixedly connected to the inside of the base 1. The movable seat 45, the limiting frame 46, the insert rod 47, the protective plate 48 and the clamping plate 49 are all located inside the protective box 491, so as to ensure the stability of the movable seat 45 when it moves through the guide rod 44.

[0036] The top of the inner side of the protective plate 48 is in contact with the top of the connecting shaft 7, and the right side of the clamp 49 is in contact with the left side of the circuit breaker body 3. An insulating pad is provided on the right side of the clamp 49 to facilitate further fixation of the circuit breaker body 3 through the clamp 49.

[0037] The protective cover 41, servo motor 42, threaded rod 43, guide rod 44, moving seat 45, limit frame 46, plug rod 47, protective plate 48, clamping plate 49 and protective box 491 are provided in two sets and are symmetrically distributed on the left and right sides of the circuit breaker body 3. By setting two sets, the stability of the circuit breaker body 3 during use can be further guaranteed.

[0038] Example 2

[0039] Please see Figure 1-6Furthermore, based on Embodiment 1, the second fixing mechanism 5 includes a support arm 51, which is fixedly connected to the front and rear sides of the protective box 491. A slide rail 52 is fixedly connected to the bottom of the support arm 51, and the slide rail 52 is slidably connected to the top of the base 1. A fixed shaft 53 is threadedly connected inside the slide rail 52.

[0040] The fixed shaft 53 runs through the interior of the base 1. There are two sets of support arms 51, slide rails 52 and fixed shafts 53, which are symmetrically distributed on the front and rear sides of the two sets of protective boxes 491. This makes it easy to ensure the stability of slide rails 52 through fixed shafts 53, thereby ensuring the stability of protective boxes 491.

[0041] In actual operation, when this device is used, when the high voltage circuit breaker needs to be installed during use, first fix the fixing base 2 to the outdoor utility pole with external fixing equipment to ensure the stability of the base 1, and then use external hoisting equipment to hoist the circuit breaker body 3 to the top of the base 1, and make the circuit breaker body 3 drive the connecting seat 6 to slide and connect to the outer periphery of the connecting shaft 7, and at the same time make the bottom of the connecting seat 6 contact the top of the base 1 to ensure the initial stability of the circuit breaker body 3.

[0042] At this point, the servo motor 42 can drive the movable seat 45, which is threadedly connected to the threaded rod 43, to slide within the base 1 and around the guide rod 44. This allows the movable seat 45 to drive the limiting frame 46 to slide to the top of the connecting seat 6 and the outside of the connecting shaft 7. Simultaneously, it drives the insertion rod 47 to insert into the connecting shaft 7, thus limiting the connection shaft 7 and ensuring the stability of the circuit breaker body 3. Furthermore, the limiting frame 46 drives the protective plate 48 to slide to the top of the connecting shaft 7, while the protective plate 48 drives the clamping plate 49 to contact the left side of the circuit breaker body 3, thereby further fixing the circuit breaker body 3 and completing the installation work. The operation is convenient.

[0043] After the protective box 491 is fixed, it can be slid to the periphery of the movable seat 45. When the protective box 491 moves, it will drive the support arm 51 and the slide rail 52 to move, and the slide rail 52 will slide on the top of the base 1. After the protective box 491 is installed, the slide rail 52 can be fixed by the fixed shaft 53, which passes through the inside of the base 1, thus ensuring the stability of the protective box 491. This not only ensures the stability of the protective box 491, but also limits the movable seat 45, preventing the threaded rod 43 from rotating under the action of external factors, causing the movable seat 45 to loosen, affecting the stability of the installation, and improving the reliability of the equipment operation.

[0044] The protective cover 41, servo motor 42, threaded rod 43, guide rod 44, moving seat 45, limit frame 46, plug rod 47, protective plate 48, clamping plate 49 and protective box 491 are provided in two sets and are symmetrically distributed on the left and right sides of the circuit breaker body 3, so as to ensure the balance and stability of the circuit breaker body 3 during use.

[0045] The protective cover 41 around the servo motor 42 can effectively prevent dust, moisture and other impurities from entering the motor and extend the motor's service life. Key transmission components such as the moving seat 45 and the limit frame 46 are located inside the protective box 491 to avoid damage to the transmission structure from external collisions and to prevent personnel from accidentally touching the moving parts.

[0046] The circuit breaker body used in this case is model 3: ZW8-12 high-voltage circuit breaker;

[0047] Furthermore, during use, the two sets of servo motors 42 need to be connected to the power supply equipment and PLC controller near the circuit breaker body 3 to ensure the coordinated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail in this case.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
