For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In one implementation, the microswitch of the circuit breaker is only used to detect the status of the circuit breaker and cannot reset the circuit breaker in the event of an abnormal power-on state.

[0033] To address the aforementioned problems, this application provides a circuit breaker that can accurately detect its status and initialize it in case of power-on anomalies, preventing malfunctions in the control circuit. Specifically, please refer to... Figure 1 and Figure 2 As shown, the circuit breaker provided in this application embodiment includes a housing 10, a transmission mechanism 11, a handle 14 and an operating mechanism 16. The housing 10 is also provided with a control unit, a first micro switch 12 and / or a second micro switch 13 electrically connected to the control unit.

[0034] The first micro switch 12 is engaged with the transmission mechanism 11;

[0035] And / or, the second micro switch 13 engages with the handle 14;

[0036] The control unit confirms the status of the circuit breaker based on the electrical signals of the first micro switch 12 and / or the second micro switch 13;

[0037] And / or, initialize and reset the connection state of the circuit breaker in the event of an abnormal power-on condition.

[0038] The electric drive mechanism 11, handle 14 and operating mechanism 16 are linked in sequence. The electric drive mechanism 11 drives the handle 14 to rotate, and the handle 14 drives the operating mechanism 16 to realize the opening and closing of the circuit.

[0039] The electric drive mechanism 11 is connected to the drive device, which is generally a motor. The motor drives the electric drive mechanism 11 to drive the circuit. The control unit is electrically connected to the drive device. The control unit can automatically control the start and stop of the drive device, and then control the electric drive mechanism 11, the handle 14 and the operating mechanism 16 to achieve automatic opening and closing of the circuit breaker.

[0040] A first micro switch 12 or a second micro switch 13, or both, are provided inside the housing 10. The first micro switch 12 cooperates with the electric drive mechanism 11 to control and detect the operation of the electric drive mechanism 11; and / or, the second micro switch 13 cooperates with the handle 14 to control and detect the operation of the handle 14. The first micro switch 12 and / or the second micro switch 13 respectively feed back electrical signals to the control unit, which uses these signals to determine the status of the circuit breaker.

[0041] And / or, the first micro switch 12 and / or the second micro switch 13 can also drive the circuit breaker to perform initialization reset in the event of an abnormal power-on state; for example, if it is detected that the circuit breaker is not closed properly, the circuit breaker can be driven to close properly.

[0042] Therefore, in the circuit breaker provided in this application embodiment, the electric drive mechanism 11, handle 14, and operating mechanism 16 within the housing 10 are sequentially linked. The electric drive mechanism 11 drives the handle 14, thereby causing the operating mechanism 16 to operate, achieving automatic opening and closing. Furthermore, a first micro switch 12 is also provided at the position of the electric drive mechanism 11, and / or a second micro switch 13 is provided at the position of the handle 14. The first micro switch 12 and / or the second micro switch 13 are used to detect and control the operating states of the electric drive mechanism 11 and the handle 14 respectively, and feed the feedback to the control unit. The control unit confirms the state of the circuit breaker based on the electrical signals from the first micro switch 12 and / or the second micro switch 13, and / or initializes and resets the circuit breaker in the event of an abnormal power-on state. This application, through the setting of the first micro switch 12 and / or the second micro switch 13, can accurately detect the state of the circuit breaker, improving the safety and reliability of the circuit breaker; and / or, in the event of an abnormal power-on state, initializes and resets the connection state of the circuit breaker, preventing malfunctions in the control circuit, which is beneficial to improving the reliability of the circuit breaker and the control circuit.

[0043] Specifically, such as Figure 3 As shown, the electric drive mechanism 11 includes at least a sector gear 110, and a handle gear 14a is provided on the handle 14. The electric drive mechanism 11 is linked with the handle 14 through the meshing of the sector gear 110 and the handle gear 14a.

[0044] The electric drive mechanism 11 drives the handle 14 to move by meshing with the sector gear 110 and the handle gear 14a on the handle 14; the handle 14 is connected to the operating mechanism 16 through the connecting rod, and then drives the operating mechanism 16 to realize the opening and closing of the circuit.

[0045] The electric drive mechanism 11 includes at least one of the following:

[0046] At least one sector gear 110, and a handle gear 14a that meshes with the sector gear 110, so that the transmission mechanism 11 is linked with the handle 14.

[0047] At least one gear, at least one sector gear 110 meshes with at least one gear.

[0048] In one embodiment, there are at least two gears that mesh with each other, with sector gear 110 meshing with an adjacent gear.

[0049] The electric transmission mechanism 11 forms a gear set, which includes multiple gears meshing in sequence. The first gear in the gear set is used to connect with the drive device, and the last gear in the gear set is used to mesh with the sector gear 110. In this way, the drive device drives multiple gears to mesh and transmit power in sequence, and then through the transmission of the sector gear 110 and the handle gear 14a, the operation of the operating mechanism 16 is finally realized.

[0050] Furthermore, the circuit breaker includes at least one of the following:

[0051] The sector gear 110 is provided with a first boss 110a that cooperates with the first micro switch 12 to detect the meshing state of the sector gear 110 and the handle gear 14a;

[0052] The handle gear 14a is provided with a second boss 14a1 that cooperates with the second micro switch 13 to detect the opening and closing status of the circuit breaker.

[0053] The circuit breaker includes at least one of the following:

[0054] The first micro switch 12 abuts against the first boss 110a to trigger the first micro switch 12 to be turned on. The on / off state of the first micro switch 12 is used to detect the meshing state of the sector gear 110 and the handle gear 14a.

[0055] The second protrusion 14a1 abuts against the second micro switch 13 to trigger the second micro switch 13 to be turned on, and the on / off state of the circuit breaker is detected by the on / off state of the second micro switch 13.

[0056] like Figure 4 As shown, when the electric drive mechanism 11 and the first micro switch 12 are engaged, the sector gear 110 is provided with a first boss 110a. The first boss 110a abuts against the first micro switch 12 to trigger the first micro switch 12 to be turned on. The on / off state of the first micro switch 12 is used to detect the meshing state of the sector gear 110 and the handle gear 14a.

[0057] A first protrusion 110a is formed on the sector gear 110. The first protrusion 110a is used to trigger the first micro switch 12 to turn on. When the first protrusion 110a abuts against the first micro switch 12, the first micro switch 12 is turned on. When the first protrusion 110a disengages from the first micro switch 12, the first micro switch 12 is turned off. When the handle gear 14a and the sector gear 110 are just meshed, the first protrusion 110a triggers the first micro switch 12 to close and turn on. When the first micro switch 12 is always in the closed state, it indicates that the handle gear 14a and the sector gear 110 are in the meshed state. When the first micro switch 12 is in the open state, it indicates that the handle gear 14a and the sector gear 110 are in the disengaged state.

[0058] Similarly, as Figure 5As shown, a second boss 14a1 is provided on the handle gear 14a. The second boss 14a1 abuts against the second micro switch 13 to trigger the second micro switch 13 to be turned on. The on / off state of the second micro switch 13 is used to detect the opening and closing state of the circuit breaker.

[0059] The second protrusion 14a1 formed on the handle gear 14a is used to trigger the second micro switch 13 to be turned on. When the second protrusion 14a1 abuts against the second micro switch 13, the second micro switch 13 is turned on. When the second protrusion 14a1 disengages from the second micro switch 13, the second micro switch 13 is turned off. When the operating mechanism 16 is closed, the second protrusion 14a1 triggers the second micro switch 13 to close and turn on the circuit breaker. When the second micro switch 13 is in the open state, the circuit breaker is in the open state.

[0060] The detection status of a circuit breaker generally includes normal status, abnormal power-on status, and fault status. When the circuit breaker is in normal status, if the first microswitch 12 is open and / or the second microswitch 13 is open, the circuit breaker is in normal tripping status and can execute electric or manual closing commands. If the first microswitch 12 is open and / or the second microswitch 13 is closed, the circuit breaker is in normal closing status and can execute electric or manual tripping commands.

[0061] When the circuit breaker is in an abnormal power-on state, if the first micro switch 12 is closed and / or the second micro switch 13 is open, it indicates that the circuit breaker is in a state where it cannot be closed. At this time, the control unit sends a command to the drive device to continue to execute the automatic closing command. Through the sequential linkage of the automatic transmission mechanism 11, the handle 14 and the operating mechanism 16, the circuit breaker is driven to continue to close, so that the connection state of the circuit breaker is initialized and reset.

[0062] When the first micro switch 12 is closed and / or the second micro switch 13 is closed, the circuit breaker is in the closed state. The control unit sends a command to the drive device to continue executing the automatic closing command. At this time, the first micro switch 12 is driven to open, so that the handle gear 14a and the sector gear 110 are separated and the circuit breaker is initialized and reset.

[0063] It should be noted that when the second microswitch 13 is closed, it indicates that the circuit breaker is in the closed state. After the circuit breaker is closed, the handle gear 14a and the sector gear 110 need to be disengaged so that the circuit breaker can be operated to open or perform other actions via the handle 14. If the handle gear 14a and the sector gear 110 are always engaged, the handle 14 cannot be operated. Therefore, once the second microswitch 13 is closed and the circuit breaker is closed, the first microswitch 12 needs to be disconnected to disengage the handle gear 14a and the sector gear 110.

[0064] It should also be emphasized that the first micro switch 12 is opened only after the second micro switch 13 is closed, to ensure that the circuit breaker is closed and the handle gear 14a and the sector gear 110 are separated at this time.

[0065] When the circuit breaker is in a fault state, during the automatic closing process, when the first micro switch 12 and / or the second micro switch 13 are respectively opened-closed-open, it indicates that the circuit breaker is faulty, and a fault alarm will be triggered, displaying that the circuit breaker closing has failed.

[0066] When a circuit breaker malfunctions, it can be connected to the control unit via an alarm device. The alarm device is used to report the fault; there are various alarm methods, such as audible alarm or flashing red light, and there is no limitation on them.

[0067] On the other hand, an operation button 15 is also provided on the housing 10. The operation button 15 is connected to the handle 14 through a connecting rod. The operation button 15 can drive the handle 14 to rotate, thereby driving the operating mechanism 16 to realize manual opening and closing of the circuit breaker.

[0068] This application also provides an electrical device equipped with the aforementioned circuit breaker. The electrical device can be configured with at least one of the following: a distribution box, cable, distribution cabinet, motor, switch socket, lamp, air conditioner, electric water heater, electricity meter, camera, telephone, computer, etc. These electrical devices can utilize the circuit breaker-related structures of this application to achieve intelligent management, but are not limited to the intelligent management of the aforementioned electrical devices; they can also be applied to non-intelligent electrical devices in traditional industries.

[0069] This application also provides an electrical device in which the aforementioned circuit breaker is applied. The electrical device can be used in whole-house intelligence and applied in the smart home and Internet of Things industries to achieve whole-house intelligent management.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
