Abstract
Description
Technical Field
[0001] This application relates to the technical field of measuring circuit breakers, and in particular to a control mechanism and a measuring circuit breaker. Background Technology
[0002] In power systems, circuit breakers are core electrical protection devices that ensure stable system operation and equipment safety. When faults such as overloads or short circuits occur, they can quickly disconnect the circuit, preventing the fault from escalating. With rising electricity demand and the accelerated construction of smart grids, measurement circuit breakers have emerged. While retaining the traditional protection functions of circuit breakers, they add the ability to measure and monitor circuit parameters, providing massive amounts of data for power system operation and management, becoming an indispensable part of modern power systems.
[0003] In related technologies, measuring circuit breakers typically consist of a housing and a cover, with core internal components including a breaking mechanism and an operating mechanism. The breaking mechanism has a breaking handle exposed outside the cover, and its operation can be controlled by the operating mechanism to achieve circuit switching. The operating mechanism has two control modes: automatic (remote) and manual (on-site). In automatic mode, the operator can control the circuit breaker remotely via a specific signal; in manual mode, the operator must operate directly at the circuit breaker. An operating shaft is rotatably mounted on the housing. In manual control, the operator inserts the operating handle into the operating shaft and rotates the shaft, which in turn drives the operating mechanism to actuate the breaking mechanism.
[0004] In the aforementioned technologies, the operating handle used for manual control needs to be carried separately by maintenance personnel, which causes considerable inconvenience in practical work. If maintenance personnel forget to bring the operating handle, they must return to retrieve it, a process that consumes a significant amount of time and severely impacts maintenance efficiency. Given the often urgent nature of power system maintenance tasks, this inefficiency caused by the carrying issue of the operating handle indicates room for improvement. Summary of the Invention
[0005] The purpose of this application is to provide a control mechanism and a measuring circuit breaker to solve the problem in the above-mentioned related technologies where the operating handle may be forgotten, affecting the efficiency of later maintenance.
[0006] Firstly, the control mechanism provided in this application adopts the following technical solution:
[0007] A control mechanism includes an outer shell mounted on a circuit breaker body, an inner shell located within the outer shell, an inner shell cover inside the inner shell, and an outer shell cover on the outer shell. The outer shell has a guide notch. A control block is slidably mounted on the outer side of the inner shell away from the inner shell cover. The control block has a control notch for a rotating handle end to be inserted through the guide notch. A rotating disk is rotatably mounted inside the inner shell, which drives the control block to slide back and forth along the guide notch when rotated. A remote control component for rotating the rotating disk is fixedly mounted. A grip is provided outside the outer shell cover, and an operating rod is vertically fixed to the end of the grip. An operating port is provided on the outer shell cover, through which the operating rod can drive the rotating disk to rotate. A placement groove is provided on the side of the outer shell cover away from the outer shell for inserting the grip, and a placement insertion hole is provided on the bottom side of the placement groove for inserting the operating rod.
[0008] By adopting the above technical solution, the grip and operating lever are integrated into the outer casing, and a recessed slot and insertion hole are provided for storage. This eliminates the need for maintenance personnel to carry the operating handle separately, avoiding the need to return to retrieve it due to forgetting it, thus saving time and improving maintenance efficiency. Simultaneously, this design ensures that when manual control is required, the operator can quickly access the grip and operating lever for operation, making it both convenient and practical, effectively solving the problem of inconvenient handling of the operating handle affecting maintenance efficiency in related technologies.
[0009] Optionally, the end edge of the grip away from the operating lever is provided with a guide arc surface, the inner wall of the opening of the placement groove is provided with an elastic hook, and the grip is provided with a locking notch for the elastic hook to engage.
[0010] By adopting the above technical solution, a guiding arc surface is provided at the edge of the handle end to facilitate its smooth insertion into the placement slot; the inner wall of the placement slot opening is provided with an elastic hook, and a locking notch is provided on the handle for it to engage, which can effectively enhance the stability of the handle when stored and prevent it from accidentally falling out. This design ensures that the handle can be stably placed when not in use and can be easily retrieved when needed, improving the convenience and safety of operation and avoiding operational errors or equipment damage that may be caused by the handle shaking or falling off.
[0011] Optionally, the outer casing has a retrieval notch, the inner wall of the placement trough has a connecting notch that communicates with the retrieval notch, and a lever is fixed on the outer periphery of the grip towards the connecting notch.
[0012] By adopting the above technical solution, when users need to remove the handle from the placement tank, they can directly move the lever through the access notch and the connecting notch to easily remove the handle from the placement tank. This design greatly improves the convenience of handling handle retrieval, avoids situations where the difficulty in removing the handle affects operational efficiency, and ensures that maintenance personnel can quickly and smoothly perform manual control operations.
[0013] Optionally, a limiting notch is provided on the side of the grip away from the lever, and a limiting protrusion that can be engaged into the limiting notch is fixed on the inner wall of the placement groove.
[0014] By adopting the above technical solution, the cooperation between the limiting protrusion and the limiting notch can prevent unnecessary shaking or displacement of the grip handle within the placement groove, ensuring its precise positioning. This design not only improves the stability of the grip handle placement but also helps reduce noise or wear that may be caused by grip handle movement, extending the service life of the equipment, while also improving operational safety and reliability.
[0015] Optionally, an identification plate is fixed on the outer side of the control block. The identification plate is located on the side of the inner shell cover facing the outer shell. The identification plate is provided with several identification areas. The outer shell cover is provided with identification through holes. The identification through holes coincide with different identification areas when the control block slides back and forth.
[0016] By adopting the above technical solution, when the control block slides back and forth, the indicator holes will coincide with different indicator areas. This design allows users to intuitively observe the color or pattern of the corresponding indicator area through the indicator holes, thereby quickly determining the control mode (such as manual or remote) of the circuit breaker. This not only improves the convenience of operation but also enhances the safety of use, because users can quickly confirm the current status of the circuit breaker, avoid misoperation, and ensure the stable operation of the power system.
[0017] Optionally, a rotating shaft with two ends passing through the inner shell and the inner shell cover is fixed in the middle of the rotating disk. A transmission component is provided on the outer periphery of the rotating shaft extending to the outside of the inner shell. When the rotating disk rotates, the transmission component drives the control block to slide back and forth along the guide notch. An operating slot for inserting an operating rod is provided on the end of the rotating shaft near the outer shell cover.
[0018] By adopting the above technical solution, a rotating shaft passing through the inner housing and inner housing cover is fixed in the middle of the rotating disk, and a transmission component is set on its outer periphery. When the rotating disk rotates, the control block can be driven to slide through the transmission component, realizing the integration of power transmission and control functions. At the same time, an operating slot is opened at the end of the rotating shaft near the outer housing cover for the insertion of an operating rod, so that the rotating shaft can be directly driven to rotate through the operating rod during manual operation, thereby controlling the sliding of the control block. This design not only ensures the realization of remote control, but also facilitates manual operation, improves the flexibility and convenience of operation, and ensures that the circuit breaker can operate stably and reliably in different scenarios.
[0019] Optionally, the transmission component is a rotating cam fixed on the outer periphery of the rotating shaft. An adjusting wheel is installed on the side of the rotating cam facing the control block. The control block has a control slide for the adjusting wheel to be inserted and slid. When the adjusting wheel rotates with the rotating cam, it drives the control block to slide back and forth.
[0020] By adopting the above technical solution, when the rotating shaft drives the rotating cam to rotate, the adjusting wheel slides within the control slide, thereby driving the control block to slide back and forth. This design achieves an effective conversion between rotation and sliding, the transmission structure is simple and reliable, and it can accurately control the movement trajectory and position of the control block, ensuring the accuracy and stability of circuit breaker operation.
[0021] Optionally, the remote control component includes a gear set disposed within the inner housing and a drive motor for driving the gear set. Teeth that mesh with the gear set are uniformly fixed on the outer periphery of the rotating disk. A micro switch for controlling the operation of the drive motor is provided on the side of the inner housing cover facing the outer housing cover.
[0022] By adopting the above technical solution, the remote control unit utilizes a gear set and a drive motor to achieve remote operation. The evenly fixed teeth on the outer circumference of the rotating disk mesh with the gear set, ensuring smooth and efficient power transmission. A microswitch on the inner cover controls the drive motor's operation, enabling flexible switching between remote control modes. This design not only enhances the reliability and accuracy of remote circuit breaker control but also facilitates mode selection via the microswitch, improving operational convenience and safety, and meeting the demands of modern power systems for intelligent and remote circuit breakers.
[0023] Optionally, an installation gap is provided between the outer shell cover and the inner shell cover. An adjusting plate is slidably mounted on the outer surface of the outer shell cover. A trigger element is fixed on the adjusting plate. A guide hole is provided on the outer shell cover for the trigger element to pass through and be inserted into the installation gap. The adjusting plate can slide back and forth between the rotating shaft and the micro switch and be fixed. When the adjusting plate slides closer to the micro switch, it can trigger the micro switch to switch to manual mode and release the operation port blockage. When the adjusting plate slides closer to the rotating shaft, it can stop triggering the micro switch to switch to automatic mode and block the operation port.
[0024] By adopting the above technical solution, the adjusting plate slides on the outside of the housing cover, and the trigger element on it is inserted into the installation gap through the guide hole. It can trigger or detour the microswitch according to the sliding position, realizing flexible switching between manual and automatic modes. Simultaneously, the adjusting plate can also block or unblock the operating port when sliding, ensuring that the operating lever cannot be accidentally operated in automatic mode, enhancing operational safety and reliability. This design makes mode switching more intuitive and convenient, effectively prevents misoperation, improves the flexibility and safety of circuit breaker use, and meets the needs of different scenarios.
[0025] Secondly, the measuring circuit breaker provided in this application adopts the following technical solution:
[0026] A measuring circuit breaker includes a circuit breaker body, a rotary handle mounted on the circuit breaker body, and the control mechanism.
[0027] By adopting the above technical solution, the control mechanism is integrated into the measuring circuit breaker, working in conjunction with the circuit breaker body and the rotary handle to achieve optimized integration of circuit breaker functions. The control mechanism can flexibly switch between manual and automatic modes, improving operational convenience and safety, while ensuring accurate and stable operation of the circuit breaker in measurement and circuit control. This design not only simplifies the circuit breaker's structure and improves its integration, but also enhances its applicability and reliability, allowing users to operate flexibly according to actual needs, effectively improving the management efficiency and safety of the power system.
[0028] In summary, this application includes the following beneficial technical effects:
[0029] This control mechanism integrates the grip and operating lever onto the housing cover, and includes a storage slot and insertion hole for convenient storage. This eliminates the need for maintenance personnel to carry the operating lever separately, avoiding the need to return to retrieve it due to forgetting it, thus saving time and improving maintenance efficiency. Simultaneously, this design ensures that operators can quickly access the grip and operating lever when manual control is required, making it both convenient and practical, effectively solving the problem of inconveniently carried operating levers affecting maintenance efficiency in related technologies.

[0048] The present application will be further described in detail below with reference to all the accompanying drawings.
[0049] Example 1:
[0050] Reference Figure 1a , Figure 1b and Figure 2 A control mechanism includes an outer shell 1 mounted on a circuit breaker body 7, an inner shell 3 located inside the outer shell 1, an inner shell cover 4 covering the inner shell 3, and an outer shell cover 2 covering the outer shell 1. The outer shell 1 has a guide notch 11, and a control block 31 is slidably mounted on the outer side of the inner shell 3 away from the inner shell cover 4. The control block 31 has a control notch 311 for the end of a rotating handle 8 that passes through the guide notch 11 to be engaged.
[0051] The inner shell 3 has a rotating disk 32 inside and a remote control component 33 installed to drive the rotating disk 32 to rotate. When the rotating disk 32 rotates, it can drive the control block 31 to slide back and forth along the guide notch 11, thereby controlling the rotation handle 8 that is inserted into the control notch 311 to rotate. The outer shell cover 2 has an operation port 21, and the outer shell cover 2 has a manual control component 6 that can control the rotation of the rotating disk 32 through the operation port 21.
[0052] In manual control, the user can use the manual control unit 6 to control the rotating disk 32 through the operation port 21, thereby causing the control block 31 to slide up and down; in remote control, the user can use the remote control unit 33 to control the rotating disk 32, thereby causing the control block 31 to slide up and down.
[0053] Reference Figure 3a , Figure 3b and Figure 4 The rotating disk 32 is fixed in the middle with a rotating shaft 321 that passes through the inner shell 3 and the inner shell cover 4 at both ends. The rotating shaft 321 extends to the outer periphery of the inner shell 3 and is provided with a transmission component 35. When the rotating disk 32 rotates, the transmission component 35 drives the control block 31 to slide back and forth along the guide notch 11.
[0054] The transmission component 35 is a rotating cam 351 fixed on the outer periphery of the rotating shaft 321. An adjusting wheel 352 is installed on the side of the rotating cam 351 facing the control block 31. The control block 31 has a control slide 312 for the adjusting wheel 352 to be inserted and slid. When the adjusting wheel 352 rotates with the rotating cam 351, it drives the control block 31 to slide back and forth.
[0055] Reference Figure 3b and Figure 4 The remote control unit 33 includes a gear set 331 disposed in the inner housing 3 and a drive motor 332 that drives the gear set 331 to rotate. Teeth 322 that mesh with the gear set 331 are evenly fixed on the outer periphery of the rotating disk 32. A micro switch 34 for controlling the operation of the drive motor 332 is provided on the side of the inner housing cover 4 facing the outer housing cover 2.
[0056] The gear set 331 includes several transmission gears rotatably disposed inside the inner housing 3 and a first gear fixed on the output shaft of the drive motor 332. The several transmission gears mesh with the first gear and the teeth 322 on the rotating disk 32. Therefore, the first gear on the drive motor 332 drives the rotating disk 32 to rotate through the several transmission gears. The gear set 331 is a conventional gear structure, which will not be described in detail here.
[0057] Reference Figure 5 and Figure 6An installation gap is provided between the outer shell cover 2 and the inner shell cover 4. An adjustment component 5 is provided on the outside of the outer shell cover 2. The adjustment component 5 includes an adjustment plate 51 that slides on the outer side of the outer shell cover 2. A trigger 52 is fixed on the adjustment plate 51. A guide hole 22 is provided on the outer shell cover 2 for the trigger 52 to pass through and be inserted into the installation gap.
[0058] The adjusting plate 51 can slide back and forth between the rotating shaft 321 and the micro switch 34 and be fixed; when the adjusting plate 51 slides closer to the micro switch 34, it can trigger the micro switch 34 to switch to manual mode and release the blockage of the operation port 21; when the adjusting plate 51 slides closer to the rotating shaft 321, it can stop triggering the micro switch 34 to switch to automatic mode and block the operation port 21.
[0059] Reference Figure 5 and Figure 6 The trigger 52 includes a fixing block 521 inserted into the guide through hole 22 and a trigger plate 522 fixed on one side of the fixing block 521, wherein the trigger plate 522 is located in the installation gap; the side of the fixing block 521 away from the trigger plate 522 is engaged and fixed with the adjustment plate 51.
[0060] Reference Figure 7a Two guide protrusions 23 with a length direction parallel to the guide through hole 22 are fixedly provided on the side of the outer shell cover 2 facing the inner shell cover 4; the two guide protrusions 23 are arranged opposite to each other on both sides of the guide through hole 22, wherein the opposite sides of the trigger plate 522 can abut against the sides of the two guide protrusions 23 that are close to each other.
[0061] On the opposite sides of the trigger plate 522, there are integrally formed elastic clips 523, and on the elastic clips 523, there are integrally formed arc-shaped protrusions 5231; and on the sides of the two guide protrusions 23 that are close to each other, there are a number of positioning grooves 231 for the arc-shaped protrusions 5231 to be inserted along their own length direction.
[0062] When the adjusting plate 51 drives the trigger plate 522 to slide to a certain position (for example, when sliding upwards, it triggers the micro switch 34; when sliding downwards, it blocks the operation port 21), the arc-shaped protrusion 5231 can be inserted into the corresponding positioning groove 231 to fix the sliding state of the adjusting plate 51; moreover, the elastic plate 523 has elastic deformation properties, and when the user applies force to drive the adjusting plate 51 to slide, the arc-shaped protrusion 5231 can be dislodged from the positioning groove 231 again.
[0063] Reference Figure 7b and Figure 8The manual control component 6 includes a grip 61 and an operating lever 62 vertically fixed to the end of the grip 61. The operating lever 62 passes through the operating port 21 and can drive the rotating disk 32 to rotate. An operating slot 3211 for inserting the operating lever 62 is provided on the end of the rotating shaft 321 near the outer cover 2. A placement groove 24 for inserting the grip 61 is provided on the side of the outer cover 2 away from the outer cover 1. The placement groove 24 is perpendicular to the length direction of the guide through hole 22. A placement insertion hole 241 for inserting the operating lever 62 is provided on the bottom side of the placement groove 24.
[0064] Reference Figure 8 and Figure 9 The end edge of the grip 61 away from the operating lever 62 is integrally formed with a guide arc surface 611. The inner wall of the opening of the placement groove 24 is provided with an elastic hook 244. The grip 61 is provided with a locking notch 613 for the elastic hook 244 to be engaged. The side of the grip 61 away from the lever 614 is provided with a limiting notch 612. The inner wall of the placement groove 24 is fixed with a limiting protrusion 242 that can be engaged in the limiting notch 612.
[0065] When the handle 61 is placed inside the placement groove 24, the limiting protrusion 242 is inserted into the corresponding limiting notch 612, and the elastic hook 244 is engaged into the corresponding locking notch 613, thereby improving the stability of the handle 61 when it is stored in the inner wall of the placement groove 24.
[0066] Reference Figure 8 and Figure 9 The outer casing 1 has a retrieval notch 12, and the inner wall of the placement groove 24 has a connecting notch 243 communicating with the retrieval notch 12. A lever 614 facing the connecting notch 243 is fixed on the outer periphery of the grip 61. When the user needs to remove the grip 61 from the placement groove 24, he / she can move the lever 614 through the retrieval notch 12 and the connecting notch 243 to remove the grip 61 from the placement groove 24.
[0067] Reference Figure 10 and Figure 11 A label plate 36 is fixed on the outer side of the control block 31. The label plate 36 is located on the side of the inner cover 4 facing the outer cover 1. The label plate 36 is provided with several label areas 361, and each label area 361 can be coated with a different color. The outer cover 2 is provided with a label through hole 25. The label through hole 25 coincides with different label areas 361 when the control block 31 slides back and forth. The user can observe the color of the corresponding label area 361 through the label through hole 25 and more intuitively judge what control mode the circuit breaker is in.
