Description
Technical Field
[0001] This utility model relates to the field of high-voltage circuit breaker technology, and in particular to a buffer structure for the operating mechanism of a high-voltage circuit breaker. Background Technology
[0002] High-voltage circuit breakers, a type of high-voltage electrical switch, are known as "high-voltage switches" and are indispensable equipment in substations. They play a crucial role in power systems. Under normal conditions, circuit breakers are responsible for interrupting and closing no-load and load currents in the circuit; however, in the event of a system fault, the circuit breaker, through its protective devices, quickly interrupts overload or short-circuit currents, thereby ensuring the safe and stable operation of the power system.
[0003] CN2020210039742, a prior application of this applicant, describes a high-safety high-voltage circuit breaker. The circuit breaker includes a mounting base, a housing fixedly connected to the upper surface of the mounting base, a slide rail on the front surface of the housing, a movably connected insert plate inside the slide rail, a baffle bar on the upper surface of the insert plate, a ventilation opening inside the insert plate, a filter screen inside the ventilation opening, and a spring fixedly connected to the inner bottom of the housing. This invention, by incorporating a baffle bar and a connector base, avoids operations around the circuit breaker during connection, increasing safety. The inclusion of cooling pipes and a heat sink facilitates cooling of the vacuum circuit breaker. The ventilation opening and fan activate when the temperature sensor detects a high temperature, increasing air convection and rapidly reducing the temperature. Additionally, the addition of reinforcing rods strengthens the housing, providing better protection for the circuit breaker.
[0004] Operating mechanisms are electrical control devices used to operate high-voltage circuit breakers, high-voltage load switches, and high-voltage disconnect switches. A buffer structure is required in conjunction with the operating mechanism during operation. Current high-voltage circuit breaker operating mechanisms are typically used in various locations, meaning they need to be installed in multiple environments. However, current buffer structures have relatively limited functionality and are difficult to adapt to different locations, resulting in significant shortcomings in installation and use. Therefore, this application proposes a buffer structure for high-voltage circuit breaker operating mechanisms. Utility Model Content

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention discloses a buffer structure for the operating mechanism of a high-voltage circuit breaker, which includes: a buffer assembly 1, a connecting assembly 2 installed below the buffer assembly 1, and an installation assembly 3 installed on the connecting assembly 2; the buffer assembly 1 includes a buffer cylinder 11, the connecting assembly 2 is fixedly connected to the bottom of the buffer cylinder 11, a top cover 12 is fixedly connected to the top of the buffer cylinder 11, a movable column 13 is movably installed through the top cover 12, a spring 16 is fixedly connected between the bottom of the movable column 13 and the bottom of the inner wall of the buffer cylinder 11, and a fixing member 14 is fixedly connected to the top of the movable column 13, and a plurality of fixing holes 15 are provided on the fixing member 14.
[0030] Specifically, the entire device is installed in a suitable position using the installation component 3. Then, the angle of the buffer cylinder 11 is adjusted using the connecting component 2. After adjustment, the buffer cylinder 11 is installed on the operating mechanism using the fixing component 14 and multiple fixing holes 15. When the operating mechanism applies force to the fixing component 14, the fixing component 14 drives the movable column 13 to move. The movable column 13 compresses the spring 16 inside the buffer cylinder 11. The elastic contraction of the spring 16 absorbs the force on the movable column 13 and drives the movable column 13 to reset after buffering. This process is repeated to achieve the buffering operation of the Caodong component.
[0031] In this embodiment, as Figure 4 As shown; the buffer assembly 1 also includes a movable ring 17, which is sleeved and fixedly installed on the outer wall of the movable column 13, and the movable ring 17 is located in the inner cavity of the buffer cylinder 11. A plurality of vertical rods 18 are fixedly connected between the bottom of the top cover 12 and the bottom of the inner wall of the buffer cylinder 11. The plurality of vertical rods 18 all pass through the movable ring 17 and are movably connected to the movable ring 17.
[0032] Specifically, during the movement of the movable column 13, the outer movable ring 17 will move synchronously. The movable ring 17 slides on multiple vertical rods 18. The multiple vertical rods 18 limit the movement trajectory of the movable ring 17 and even the movable column 13, thereby improving stability.
[0033] In this embodiment, as Figure 5 As shown; the mounting component 3 includes a screw 31, the end of which is fixedly connected to the connecting component 2, and a threaded sleeve 32 is threadedly connected to the outside of the screw 31. An mounting part 33 is fixedly mounted on the outer wall of the threaded sleeve 32, and multiple mounting holes 34 are provided on the mounting part 33.
[0034] Specifically, the entire device is installed in a suitable position using the mounting part 33 and multiple mounting holes 34. Depending on the space available in the actual location, the screw 31 or threaded sleeve 32 can be rotated to achieve the purpose of extension and retraction, thereby changing the position of the buffer cylinder 11 and providing a better buffering effect.
[0035] In this embodiment, as Figures 4-5 As shown; the multiple mounting holes 34 and the multiple fixing holes 15 are all elongated strips.
[0036] Specifically, this design allows for the selection of a suitable position for fixing when the fixing bolt passes through the mounting hole 34 and the fixing hole 15, improving the convenience of the installation process.
[0037] In this embodiment, as Figure 5 As shown; the connecting component 2 includes a fixed block 21, a movable block 22 is movably installed in the inner cavity of the fixed block 21, and a round shaft 23 is fixedly installed through the movable block 22. The two ends of the round shaft 23 pass through the outer wall of the fixed block 21 and are rotatably connected to the outer wall of the fixed block 21.
[0038] Specifically, the movable block 22 and the fixed block 21 are connected by the circular shaft 23, which allows the angle between the buffer cylinder 11 and the screw 31 to be adjusted, thus achieving a better buffering effect.
[0039] In this embodiment, as Figure 5 As shown; both ends of the round shaft 23 are threaded with fastening nuts 24.
[0040] Specifically, after adjusting the angle, the fastening nut 24 is used to fix it, thereby improving stability.
[0041] In this embodiment, as Figures 3-5 As shown; the fixed block 21 is fixedly connected to the bottom of the buffer cylinder 11, and the movable block 22 is fixedly connected to the end of the screw 31.
[0042] Specifically, the above settings enable the connection between the screw 31 and the buffer cylinder 11, thereby enabling a series of angle and position adjustments.
[0043] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
