Description

Technical Field

[0001] The present application relates to the technical field of measuring circuit breakers, and in particular to a control mechanism and a measuring circuit breaker. Background Art

[0002] In power systems, circuit breakers are core electrical protection devices that ensure stable system operation and equipment safety. When faults such as overloads and short circuits occur, they quickly disconnect the circuit to prevent further damage. With rising electricity demand and the accelerated development of smart grids, measuring circuit breakers have emerged. While retaining the protection functions of traditional circuit breakers, they also add circuit parameter measurement and monitoring capabilities, providing massive amounts of data for power system operation and management, making them an indispensable component of modern power systems.

[0003] In related technologies, measuring circuit breakers typically consist of a housing and a cover, with the core internal components including a disconnect mechanism and an operating mechanism. The disconnect mechanism is equipped with a disconnect handle exposed outside the housing cover, which can be controlled by the operating mechanism to achieve circuit on / off. The operating mechanism has two control modes: automatic (remote) and manual (on-site). In automatic mode, the operator can remotely control the circuit breaker using specific signals; in manual mode, the operator must operate the circuit breaker directly at the circuit breaker. An operating shaft is rotatably mounted on the housing. During manual control, the operator plugs the operating handle into the operating shaft and rotates the operating shaft, thereby driving the operating mechanism to activate the disconnect mechanism.

[0004] In the aforementioned related technologies, maintenance personnel must carry the manual control handle separately, which is inconvenient during actual work. If maintenance personnel forget to carry the handle, they must return to retrieve it, which is a time-consuming process and seriously affects maintenance efficiency. Given the urgent nature of power system maintenance tasks, this inefficiency caused by the difficulty of carrying the handle leaves 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 art that the operating handle may be forgotten to be carried, thereby affecting the efficiency of subsequent maintenance.

This design allows the user to intuitively identify the color or pattern of the corresponding identification zone through the identification holes, allowing them to quickly determine the circuit breaker's control mode (e.g., manual or remote). This not only improves operational convenience but also enhances safety, allowing users to quickly confirm the circuit breaker's current status, avoiding misoperation and ensuring stable operation of the power system.

[0016] Optionally, a rotating shaft is fixed to the middle of the rotating disk, with both ends passing through the inner shell and the inner shell cover respectively.

When the rotating disk rotates, the transmission member can drive the control block to slide, realizing the integration of power transmission and control functions. At the same time, an operating slot is provided at the end of the rotating shaft near the outer shell cover for the insertion of an operating lever. During manual operation, the operating lever can directly drive the rotating shaft to rotate, thereby controlling the sliding of the control block. This design not only ensures the implementation 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.

The teeth uniformly fixed around the outer periphery of the rotating disk mesh with the gear train, ensuring smooth and efficient power transmission. A microswitch on the inner housing cover controls the operation of the drive motor, enabling flexible switching of remote control modes. This design not only enhances the reliability and accuracy of remote control of the circuit breaker, 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.

[0022] Optionally, an installation gap is provided between the outer shell cover and the inner shell cover, an adjustment plate is slidingly provided on the outer side surface of the outer shell cover, a trigger member is fixed on the adjustment plate, and a guide through hole is opened on the outer shell cover for the trigger member to pass through and insert into the installation gap; the adjustment plate can slide back and forth between the rotating shaft and the micro switch and be fixed; when the adjustment plate slides close to the micro switch, it can trigger the micro switch to switch to manual mode and release the blockage of the operation port; when the adjustment plate slides in the direction close to the rotating shaft, it can stop triggering the micro switch to switch to automatic mode and block the operation port.

[0023] By adopting this technical solution, the adjustment plate slides on the outside of the outer cover, and the trigger member on it is inserted into the installation gap through the guide hole. It can trigger or release the micro switch according to the sliding position, realizing flexible switching between manual and automatic modes. At the same time, the adjustment plate can also block or release the operating port when sliding, ensuring that the operating lever cannot be accidentally operated in automatic mode, enhancing the safety and reliability of operation. This design makes mode switching more intuitive and convenient, and can effectively prevent misoperation, improving the flexibility and safety of circuit breaker use, and meeting the needs of use in different scenarios.

[0024] In a second aspect, the present application provides a measuring circuit breaker that adopts the following technical solution: A measuring circuit breaker comprises a circuit breaker body, a rotating handle installed on the circuit breaker body and the control mechanism.
