Description

Technical Field

[0001] This invention relates to the field of testing device technology, and in particular to an intelligent testing and calibration device for the mechanical characteristics of high-voltage circuit breakers. Background Technology

[0002] High-voltage switches are widely used in power systems to cut off and connect load currents, and can work with relay protection devices to quickly isolate faults and ensure the safe and stable operation of the power system. Therefore, before being put into use or during power outage maintenance, high-voltage switches require electrical tests to ensure they meet normal operating conditions. When using testing devices to perform mechanical performance tests on high-voltage circuit breakers in the field, the testing device's connector needs to be electrically connected to the circuit breaker's aviation connector. However, currently, the connectors of testing devices are not compatible with different types of high-voltage circuit breakers, requiring frequent changes of different testing devices for different types of circuit breakers, resulting in low testing efficiency.

[0003] An existing patent (publication number: CN120404107A) discloses a circuit breaker mechanical performance testing device and its testing method. The circuit breaker mechanical performance testing device includes a plug-in module that is electrically connected to an aviation plug in the circuit breaker. The aviation plug has a first conductive post or a first conductive bushing. The plug-in module has a docking assembly, which includes a second conductive post and a sleeve.

[0004] Although this application can be connected to the corresponding sleeve and the second conductive post slidably connected to the sleeve, making the plug module of this application compatible with the aviation plugs of various circuit breakers, this application lacks an effective guiding structure. When plugging the plug module to the aviation plug, it is not convenient to align the mating component on the plug module with the conductive post of the aviation plug, resulting in a long plugging process and easy problems such as inaccurate plugging and poor contact. At the same time, after the mating is completed, the rotating clamping component applies pressure to the conductive post on one side, which can easily cause uneven force on the conductive post and deformation, affecting the accuracy of the test results, and may even damage the aviation plug of the high-voltage circuit breaker. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent detection and calibration device for the mechanical characteristics of high-voltage circuit breakers, so as to solve the problems mentioned in the background art.

[0008] Preferably, the transmission chamber has a movable groove inside, the gear passes through the movable groove, and an auxiliary rod is fixed to the inner wall of the transmission chamber, with the lower end of the auxiliary rod fixed to the upper surface of the limiting block.

[0009] Preferably, the fixing unit includes a fixing block that moves on the moving unit, the fixing block has a movable compartment inside, a rotating rod is rotatably connected to the inner wall of the movable compartment, and a protrusion is fixed on the surface of the rotating rod.

[0011] Preferably, a slider is fixed on the lower surface of the movable block, and a corresponding groove is provided on the upper surface of the mounting frame. The slider moves inside the groove, and the movable block and the fixed block move on the surface of the mounting frame through the slider and the groove.

This ensures that the axis of the connector and the conductive post are always aligned, effectively avoiding poor contact or component damage caused by misaligned insertion. At the same time, the arc-shaped surface of the limiting block corresponding to the connector can make the clamping force evenly distributed, preventing local stress concentration that could lead to deformation of the conductive post.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] This invention provides, for example Figures 1 to 9The intelligent detection and calibration device for the mechanical characteristics of a high-voltage circuit breaker shown includes a high-voltage switch mechanical characteristic detector 1 and a circuit breaker body 2. An aviation plug 201 is mounted on the circuit breaker body 2. A connector 101 is mounted on the side of the high-voltage switch mechanical characteristic detector 1. An auxiliary component 3 is also included, mounted on the side of the aviation plug 201. The auxiliary component 3 is used for positioning and fixing the connector 101. The auxiliary component 3 includes a mounting frame 301, a moving unit 302 movable on the mounting frame 301, and a fixing unit 303. One end of the connector 101 can pass through the moving unit 302. The moving unit 302 is fixed to the mounting frame 301 by the fixing unit 303. A pointer 305 is also fixed to the upper surface of the fixing unit 303. A second conductive post 202 is provided on the side of the aviation plug 201. The moving unit 302 is adjusted to align with the second conductive post 202 by the pointer 305. At the relatively aligned position, the connector 101 has a first conductive post 104 fixed inside. The connector 101 is electrically connected to the aviation plug 201 through the first conductive post 104 and the second conductive post 202. The moving unit 302 is adjusted to the position corresponding to the second conductive post 202, which solves the problem of difficult alignment during insertion in the prior art and shortens the insertion time. At the same time, the connector 101 passes through the moving unit 302. With the fixing unit 303 fixing the moving unit 302, the connector 101 and the aviation plug 201 are accurately positioned, avoiding inaccurate insertion and poor contact. Furthermore, the wrapping limit of the connector 101 by the moving unit 302 can make the second conductive post 202 and the first conductive post 104 evenly stressed, preventing the conductive post from deforming. This not only improves the accuracy of the test results, but also avoids damage to the aviation plug 201 of the high-voltage circuit breaker.

[0019] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6The moving unit 302 includes a moving block 3028 movable on the mounting frame 301. A transmission chamber 3021 is formed inside the moving block 3028. A threaded rod 3022 is rotatably connected to the inner wall of the transmission chamber 3021. A threaded tube 3023 is threadedly connected to the surface of the threaded rod 3022. A gear 3026 is fixed to the surface of the threaded rod 3022 and is positioned above the threaded tube 3023. A limiting groove 2029 is formed on the surface of the moving block 3028. A connector 101 passes through the limiting groove 2029. A guide plate 102 is fixed to the circumferential surface of the connector 101. A toothed plate 103 is embedded on the side of the guide plate 102. The gear 3026 and the toothed plate 103 mesh. A [missing information - likely a device or component] is fixed to the lower surface of the threaded tube 3023. The limiting block 3024 has an arc-shaped surface on its side that corresponds to the plug 101. The guide plate 102 and the limiting groove 2029 cooperate to guide the plug 101. Subsequently, when the plug 101 is inserted, it will drive the guide plate 102 to move synchronously. The toothed plate 103 on the side of the guide plate 102 meshes with the gear 3026, which in turn drives the threaded rod 3022 to rotate. The threaded rod 3022 drives the threaded tube 3023 to move the limiting block 3024. Since the arc-shaped surface of the limiting block 3024 is adapted to the plug 101, the limiting block 3024 can fit tightly against the surface of the plug 101, thereby limiting the plug 101 and preventing it from shaking in the limiting groove 2029.

[0020] Since the rotation angle of gear 3026 is strictly determined by the linear movement distance of toothed plate 103 (i.e., the insertion stroke of connector 101), and the transmission ratio of gear 3026 rack is fixed, and the thread lead of threaded rod 3022 is also fixed, each unit length inserted by connector 101 will drive limit block 3024 to generate a fixed and precise radial displacement. Thus, regardless of the insertion speed of connector 101, as long as connector 101 is fully in place, the final clamping position of limit block 3024 is always fixed. This avoids the risk of poor contact due to shallow insertion or damage to components due to deep insertion, as well as connector wear or damage caused by improper insertion, thereby improving the repeatability and accuracy of test data.

[0021] Please see Figure 5The transmission chamber 3021 has a movable groove 3027 inside, and the gear 3026 passes through the movable groove 3027. An auxiliary rod 3025 is also fixed to the inner wall of the transmission chamber 3021. The lower end of the auxiliary rod 3025 is fixed to the upper surface of the limiting block 3024. The movable groove 3027 provides rotation space for the gear 3026, avoiding interference between the gear 3026 and the inner wall of the transmission chamber 3021 when the gear 3026 rotates, and ensuring the smooth meshing and transmission between the gear 3026 and the gear plate 103. The auxiliary rod 3025 plays a guiding and supporting role in the movement of the limiting block 3024, preventing the limiting block 3024 from deviating or jamming when it moves, and ensuring that the limiting block 3024 can stably fit the connector 101.

[0022] Please see Figure 4 and Figure 6 The fixed unit 303 includes a fixed block 3037 movable on the moving unit 302. A movable chamber 3031 is formed inside the fixed block 3037. A rotating rod 3032 is rotatably connected to the inner wall of the movable chamber 3031. A protrusion 3033 is fixed to the surface of the rotating rod 3032. A fixing groove 3038 is formed on the inner wall of the chamber 3021. A fixing rod 3034 passes through the fixing groove 3038. The protrusion 3033 is in contact with the end face of the fixing rod 3034. A first spring is sleeved on the outer periphery of the fixing rod 3034. The other end face of the fixing rod 3034 is in contact with the fixing frame. An indicator block 3035 is fixed to the upper surface of the rotating rod 3032. A position indicator groove 3036 corresponding to the fixing rod 3034 is formed on the upper surface of the fixed block 3037. The position of indicator block 3035 corresponds to the position slot 3036. Rotating the rotating rod 3032 causes the protrusion 3033 to rotate. The protrusion 3033 pushes the fixed rod 3034 to slide in the fixed slot 3038 and compress the first spring. When the indicator block 3035 rotates to the position of the position slot 3036, it indicates that the fixed rod 3034 has moved to the appropriate position. At this time, stop rotating the rotating rod 3032. At this time, the end face of the fixed rod 3034 is tightly attached to the inner wall of the transmission chamber 3021, thereby fixing the moving block 3028 on the mounting bracket 301, realizing the fixation of the moving unit 302, ensuring the stability of the connector 101 after it is plugged into the aviation plug 201, and preventing loosening or displacement during the testing process, which would affect the accuracy of the test results.

[0023] Please see Figure 2 , Figure 3 , Figure 8 and Figure 9A slider 304 is fixed to the lower surface of the movable block 3028, and a corresponding groove 3014 is provided on the upper surface of the mounting bracket 301. The slider 304 moves inside the groove 3014. The movable block 3028 and the fixed block 3037 move on the surface of the mounting bracket 301 through the slider 304 and the groove 3014. A baffle 306 is rotatably connected to the side of the movable block 3028 through a torsion spring. The slider 304 and the groove 3014 provide guidance for the movement of the movable block 3028, ensuring the smoothness and straightness of the movement of the movable block 3028, preventing it from deviating during the movement, and ensuring that the movable block 3028 can accurately move to the position corresponding to the second conductive post 202. At the same time, the baffle 306 connected by the torsion spring plays a certain protective and positioning assistance role during the movement of the movable block 3028.

[0024] Please see Figure 2 and Figure 3 The mounting bracket 301 has a telescopic groove 3011 on its side. A telescopic rod 3012 is fixed to the inner wall of the telescopic groove 3011. A clamping block 3013 is fixed to one end of the telescopic rod 3012. The side of the clamping block 3013 fits against the side of the aviation plug 201. A second spring is sleeved on the outer periphery of the telescopic rod 3012. A connecting rod 3015 is also fixed to the lower surface of the mounting bracket 301. There are two mounting brackets 301, and the lower end of the connecting rod 3015 is fixed to the upper surface of another mounting bracket 301. The telescopic groove 3011, the telescopic rod 3012, and the second spring are connected. The spring mechanism allows the clamping block 3013 to fit different sizes of aviation plugs 201. Furthermore, the rebound force of the second spring ensures that the clamping block 3013 fits tightly against the side of the aviation plug 201, enabling the mounting bracket 301 to stably engage with the aviation plug 201. This prevents the mounting bracket 301 from shifting position due to vibration or external force during testing, ensuring the stability and accuracy of the testing. At the same time, the connecting rod 3015 connects the two mounting brackets 301 together to form an integrated structure, enhancing the strength and stability of the auxiliary component 3.

[0025] It should be noted that the insertion end of the connector 101 has an arc-shaped surface. When it contacts the second conductive post 202, the arc-shaped surface can play a certain guiding role, guiding the second conductive post 202 to be inserted smoothly. In addition, the arc-shaped surface design can disperse the pressure generated during insertion, avoiding excessive local pressure from damaging the second conductive post 202, and further ensuring the integrity of the conductive post. The moving unit 302 can flexibly adjust its position on the mounting bracket 301 with the help of the slider 304 and the slide groove 3014. With the help of the pointer 305, it can quickly and accurately align the second conductive post 202 of the aviation plug 201. The fixing unit 303 drives the protrusion 3033 to drive the fixing rod 3034 through the rotating rod 3032, which firmly locks the moving unit 302 in the target position. The cooperation between the indicator block 3035 and the positioning groove 3036 can intuitively confirm that the fixed position is in place and avoid displacement. Thus, it efficiently solves the problems of difficult insertion and alignment and long time consumption in traditional devices.

[0026] In addition, when the connector 101 is inserted, the guide plate 102 and the limiting groove 2029 cooperate to achieve precise guidance of the connector 101. At the same time, the toothed plate 103 and the gear 3026 mesh and drive the limiting block 3024 to tightly fit the connector 101 with a wrapping arc surface, forming a uniform circumferential limit, preventing poor contact caused by the shaking of the connector 101, and ensuring the stability of the electrical connection. The uniform circumferential limit makes the first conductive post 104 and the second conductive post 202 bear forces in balance, effectively avoiding the risk of deformation and damage of the conductive posts due to uneven force. In addition, the combination of the flexible adjustment of the moving unit 302 and the quick locking of the fixed unit 303 allows the device to be adapted to the aviation plug 201 of different specifications of circuit breakers without replacement, improving the versatility of the device, reducing the replacement frequency of the testing device, improving testing efficiency, ensuring the accuracy of the test results and the safety of the equipment.

[0027] The working principle of the above embodiments is as follows: First, the auxiliary component 3 is installed on the side of the aviation connector 201 of the circuit breaker body 2. Specifically, the operator adjusts the position of the clamping block 3013 according to the specifications of the aviation connector 201, so that the side of the clamping block 3013 fits against the side of the aviation connector 201. Then, under the return force of the second spring, the mounting bracket 301 is fixed on the aviation connector 201. Next, the operator adjusts the position of the moving unit 302 according to the position of the second conductive post 202 on the aviation connector 201, in conjunction with the pointer 305 installed on the upper surface of the moving unit 302. Then, the operator turns the rotating rod 3032, which drives the protrusion 3033 fixed on the surface to rotate. After the protrusion 3033 contacts the fixing rod 3034, it can push the fixing rod 3034. 4. Move the fixed rod 3034 away from the movable compartment 3031 in the fixed groove 3038. During the movement, the fixed rod 3034 compresses the first spring. When the end of the fixed rod 3034 is tightly attached to the fixed frame, stop turning the rotating rod 3032. At this time, the position of the indicator block 3035 corresponds to the position slot 3036, indicating that the moving unit 302 has been fixed. Then, the operator aligns the guide plate 102 on the surface of the plug 101 with the limiting groove 2029 and pushes the plug 101 into the limiting groove 2029. At the same time, one end of the plug 101 pushes open the baffle, so that the plug 101 is inserted into the surface of the second conductive post 202, thereby enabling the plug 101 to achieve a stable electrical connection with the aviation plug 201 through the first conductive post 104 and the second conductive post 202.

[0028] During the movement of the connector 101, the guide rod fixed on the circumferential surface can be moved, thereby causing the toothed plate 103 embedded on the side of the guide rod to move synchronously. Since the toothed plate 103 and the gear 3026 mesh, the movement of the toothed plate 103 will drive the gear 3026 to rotate. The rotation of the gear 3026 will drive the threaded rod 3022 to rotate. The rotation of the threaded rod 3022 will drive the threaded tube 3023 to move on the surface of the threaded rod 3022. The movement of the threaded tube 3023 will drive the limiting block 3024 to move. During the movement of the limiting block 3024, the arc-shaped surface on its side will fit against the surface of the connector 101, thereby limiting the connector 101 and preventing the connector 101 from shaking inside the limiting groove 2029, further ensuring the stability of the electrical connection.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
