Description

Technical Field

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

[0002] A circuit breaker is a crucial electrical device used for circuit protection. It primarily provides safety protection in power systems and low-voltage distribution systems. When a fault such as an overload, short circuit, or undervoltage occurs, the circuit breaker quickly disconnects the circuit, preventing damage to electrical equipment caused by abnormal current flow and effectively preventing accidents such as fire.

[0003] Currently, more and more circuit breakers can monitor the power usage of the circuits connected to them, and users can set the circuit breaker's operating parameters based on power usage. For example, the trip current threshold can be appropriately increased if the circuit connected to the circuit breaker is a high-power appliance that frequently trips during use. However, conventional circuit breakers are typically located high up in the room or in hard-to-reach locations to prevent children from accidentally operating them. This makes it difficult for users to view and adjust the circuit breaker settings, resulting in a poor user experience. Summary of the Invention

[0004] In view of this, the present invention provides a control method for a circuit breaker and a circuit breaker to solve the problem that it is inconvenient for users to view and set the circuit breaker, resulting in a poor user experience.

[0005] In a first aspect, the present invention provides a method for controlling a circuit breaker, wherein the circuit breaker includes an actuator and a setting mechanism, the actuator being configured to at least switch a connected circuit on and off, the setting mechanism being detachably connected to the actuator so that the circuit breaker can be used in both an integrated state and a separate state. The control method includes:

[0006] Based on the usage status change signal of the circuit breaker, controlling the on / off of the wireless communication connection between the setting mechanism and the actuator;

[0007] If the usage status change signal indicates a change from the integrated state to the separated state, the setting mechanism is controlled to perform wireless communication with the execution mechanism.

[0008] Beneficial effects: The embodiment of the present invention makes the setting mechanism and the actuator detachable. When the setting mechanism is removed from the actuator, the two are in wireless communication, which makes it convenient for users to view and set the circuit breaker and improves the user experience. Furthermore, there is no need for technicians to re-operate after installation, which can improve work efficiency to a certain extent. In addition, after the setting mechanism is removed from the actuator, the setting mechanism can be taken to a position away from the actuator, and the operating distance can be selected to avoid the strong electric environment around the circuit breaker and avoid the risk of electric shock during operation. It is convenient for maintenance personnel to maintain the setting mechanism. While ensuring the normal operation of the circuit breaker, it can also reduce the safety hazards brought to maintenance personnel by the high voltage of the actuator during live maintenance or operation.

[0009] In an optional embodiment, the control method further includes: if the usage status change signal indicates a change from the separate state to the integrated state, controlling the setting mechanism to disconnect wireless communication with the execution mechanism.

[0010] Beneficial effects: The embodiment of the present invention makes the setting mechanism and the actuator detachable. When the setting mechanism is installed on the actuator, the setting mechanism and the actuator can communicate with each other via a communication cable or a communication interface. When the setting mechanism is removed from the actuator, it is directly converted to wireless communication, so that it can flexibly switch between wired communication and wireless communication according to the connection between the setting mechanism and the actuator, without the need for manual setting by the user. This makes it convenient for users to view and set the circuit breaker, improving the user experience. Furthermore, there is no need for technicians to re-operate after installation, which can improve work efficiency to a certain extent. In addition, after the setting mechanism is removed from the actuator, the setting mechanism can be taken to a position away from the actuator, and the operating distance can be selected to avoid the strong electric environment around the circuit breaker and avoid the risk of electric shock during the operation process. It is convenient for maintenance personnel to maintain the setting mechanism. While ensuring the normal operation of the circuit breaker, it can also reduce the safety hazards posed to maintenance personnel by the high voltage of the actuator during live maintenance or operation.

[0011] In an optional embodiment, the setting mechanism includes a first control module and a first interface, the first control module and the first interface are electrically connected, the actuator includes a second control module and a second interface, the second control module and the second interface are electrically connected, when the circuit breaker is in an integrated state, the first interface and the second interface are interconnected; when the circuit breaker is in a separated state, the first interface and the second interface are disconnected from each other;

[0012] The control method further includes:

[0013] When the usage status changes, the setting mechanism and the execution mechanism are connected or disconnected by wired communication, the first interface sends the usage status change signal to the first control module, and the second interface sends the usage status change signal to the second control module.

[0014] In an optional implementation manner, the first interface and the second interface have a pre-stored communication protocol, and the control method further includes:

[0015] The first interface sends a wired communication request to the second interface based on the level change signal and the communication protocol, and the second interface agrees to the wired communication request based on the communication protocol to complete the wired communication connection between the setting mechanism and the execution mechanism;

[0016] Alternatively, the second interface sends a wired communication request to the first interface based on the level change signal and the communication protocol, and the first interface agrees to the wired communication request based on the communication protocol to complete the wired communication connection between the setting mechanism and the execution mechanism.

[0017] In an optional embodiment, the matching information is a first identification code and a second identification code; the setting mechanism pre-stores the first identification code, and the executing mechanism pre-stores the second identification code; the first identification code corresponds to the executing mechanism, and the second identification code corresponds to the setting mechanism; the step of controlling the setting mechanism to wirelessly communicate with the executing mechanism includes:

[0018] The setting mechanism is controlled to send a wireless connection request to the execution mechanism according to the first identification code, and the execution mechanism responds to the wireless connection request according to the second identification code.

[0019] In an optional embodiment, when multiple actuators are provided, the setting mechanism pre-stores identification codes of the multiple actuators; when the setting mechanism is integrated with one of the actuators, the setting mechanism is connected to the actuator via wired communication, and the setting mechanism is connected to the other actuators via wireless communication;

[0020] When the setting mechanism and all the executing mechanisms are in a separate state, the setting mechanism is connected to all the executing mechanisms through wireless communication.

[0021] Beneficial effect: Since a traditional circuit breaker works in pairs with a single setting mechanism and a single actuator, the embodiment of the present invention uses a single setting mechanism to communicate with multiple actuators at the same time, so that the entire working process can be realized only by a single setting mechanism, which can significantly reduce the number of setting mechanisms used and, to a certain extent, can reduce production costs and improve product competitiveness.

[0022] In an optional embodiment, the control method further includes:

[0025] In an optional embodiment, the control method further includes:

[0026] Acquiring a current limiting signal; the current limiting signal is used to indicate a change in a current limiting threshold of the actuator;

[0046] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0047] The following combination Figures 1 to 7 , describing embodiments of the present invention.

[0048] According to an embodiment of the present invention, on the one hand, a control method for a circuit breaker is provided, wherein the circuit breaker includes an actuator 2 and a setting mechanism 1, wherein the actuator 2 is at least used to realize the on-off of the connected circuit, and the traditional actuator 2 is usually provided with a contact system, a tripping mechanism and an electronic control unit. The contact system is responsible for connecting and disconnecting the circuit. When the circuit breaker needs to be operated, the moving contact will quickly separate from the static contact to cut off the flow of current. The tripping mechanism usually performs a tripping operation after detecting an abnormal situation to ensure that the contacts are quickly disconnected. The setting mechanism 1 is detachably connected to the actuator 2 so that the use state of the circuit breaker includes an integrated state and a split state.

[0049] Furthermore, in the embodiment of the present invention, the setting mechanism 1 is at least used to set the working parameters of the actuator 2. The setting mechanism 1 is detachably mounted on the actuator 2, so that the circuit breaker can be used in an integrated state and a split state.

[0050] The control method includes:

[0051] S1. Controlling the on / off of the wireless communication connection between the setting mechanism 1 and the actuator 2 based on a usage status change signal of the circuit breaker;

[0052] During actual operation, it is necessary to obtain usage status change signals from setting mechanism 1 and actuator 2. Regarding the acquisition method, the control module of setting mechanism 1 and the control module of actuator 2 can correspondingly obtain their respective status change signals. In embodiments of the present invention, the usage status change signal can be a level change signal or a signal that changes signal type. The level change signal can change from a low level to a high level or from a high level to a low level. The signal type change signal can be a PWM signal converted to a DC signal or a DC signal converted to a PWM signal.

[0053] Of course, this embodiment is merely an example of the type of usage status change signal, but is not intended to limit this. Those skilled in the art may make changes according to actual conditions as long as the same technical effect is achieved.

[0054] Regarding the method of obtaining the usage status change signal, for example, when the setting mechanism 1 and the actuator 2 are installed by snapping together the snap-in slot, the control module of the setting mechanism 1 and the control module of the actuator 2 can obtain whether the snap-in slot is snap-in through the electrical connection switch. One end of the electrical connection switch is set on the snap, and the other end of the electrical connection switch is set in the slot. When the snap-in slot is snap-in, the electrical connection switch is turned on, and the control modules of the two can receive the connection signal. When the snap-in slot is not snap-in, the control modules of the two cannot receive the connection signal. Similarly, when screw holes are used for connection, when all the screws are completely screwed into the screw holes, the electrical connection switch is turned on, and the control modules of the two can receive the connection signal. If one of the screws is not screwed into the screw hole, the electrical connection switch cannot be turned on.

[0055] Of course, this embodiment is only an example of the method for obtaining the current connection status, but is not limited thereto. Those skilled in the art may make changes according to actual conditions as long as the same technical effect is achieved.

[0056] Therefore, the control modules of the two can obtain the usage status change signal in real time and control the on / off of the wireless communication connection between the setting mechanism 1 and the execution mechanism 2 according to the usage status change signal. In other words, the usage status change signal corresponds to the communication connection mode one by one.

[0057] S2. If the usage state change signal indicates a change from the integrated state to the separated state, controlling the setting mechanism 1 to perform wireless communication with the execution mechanism 2;

[0058] If the integrated state changes to the separated state, it indicates that the setting mechanism 1 has been separated from the actuator 2. The distance between the setting mechanism 1 and the actuator 2 is relatively large. To ensure continuous communication between the setting mechanism 1 and the actuator 2, wireless communication can be used. The types of wireless communication can be, but are not limited to, the following: Wi-Fi, Bluetooth, NB-IoT, LoRa, ZigBee, 433, etc.

[0059] With such a configuration, the embodiment of the present invention makes the setting mechanism 1 and the actuator 2 detachable. When the setting mechanism 1 is removed from the actuator 2, the two are in wireless communication, which makes it convenient for users to view and set the circuit breaker, improving the user experience. Furthermore, there is no need for technicians to re-operate after installation, which can improve work efficiency to a certain extent. In addition, after the setting mechanism 1 is removed from the actuator 2, the setting mechanism 1 can be taken to a position away from the actuator 2, and the operating distance can be selected to avoid the strong electric environment around the circuit breaker and avoid the risk of electric shock during the operation process. It is convenient for maintenance personnel to maintain the setting mechanism 1. While ensuring the normal operation of the circuit breaker, it can also reduce the safety hazards posed to maintenance personnel by the high voltage of the actuator 2 during live maintenance or operation.

[0060] Furthermore, in an optional embodiment, if the usage status change signal indicates a change from the separate state to the integrated state, the setting mechanism 1 is controlled to disconnect the wireless communication with the execution mechanism 2.

[0061] If the current connection state is the integrated state, it means that the setting mechanism 1 has been installed on the actuator 2. At this time, a simple connection can be made via a communication line, which is short, fast and efficient. Then the wireless communication can be disconnected.

[0062] In this embodiment of the present invention, the setting mechanism 1 and the actuator 2 are detachable. When the setting mechanism 1 is installed on the actuator 2, the two mechanisms can communicate wiredly via a communication cable or communication interface. When the setting mechanism 1 is removed from the actuator 2, the communication switches directly to wireless communication. This allows for flexible switching between wired and wireless communication based on the connection between the setting mechanism 1 and the actuator 2, eliminating the need for manual user configuration. This facilitates user control and configuration of the circuit breaker, improving the user experience. Furthermore, it eliminates the need for technicians to re-operate after installation, significantly improving work efficiency. Furthermore, after the setting mechanism 1 is removed from the actuator 2, it can be moved away from the actuator 2, allowing for a flexible operating distance to avoid the high voltage environment surrounding the circuit breaker and mitigate the risk of electric shock during operation. This facilitates maintenance personnel's access to the setting mechanism 1, ensuring normal circuit breaker operation while also reducing safety hazards posed by the high voltage of the actuator 2 during live maintenance or operation.

[0063] Furthermore, in an optional embodiment, the setting mechanism 1 is provided with a first control module and a first interface 12, and the first control module is electrically connected to the first interface 12. The executing mechanism 2 is provided with a second control module and a second interface 23, and the second control module is electrically connected to the second interface 23.

[0064] When the current connection state is the integrated state, the first interface 12 and the second interface 23 are connected to each other, and the setting mechanism 1 and the actuator 2 are controlled to perform wired communication through the first interface 12 and the second interface 23. When the circuit breaker is in the separated state, the first interface 12 and the second interface 23 are disconnected from each other.

[0065] To facilitate installation of the setting mechanism 1 and the actuator 2, the communication line can be replaced with the corresponding first interface 12 and second interface 23. The interface type of the first interface 12 and second interface 23 can be a USB interface, or other male or female connectors. Of course, this embodiment is merely an example of the interface type and is not intended to be limiting. Those skilled in the art can modify it according to actual circumstances, as long as the same technical effect is achieved.

[0066] Furthermore, in an optional embodiment, the control method further includes:

[0067] S3. When the usage status changes, the first interface 12 sends the usage status change signal to the first control module, and the second interface 23 sends the usage status change signal to the second control module.

[0068] In this embodiment of the present invention, the control module of the setting mechanism 1 is a first control module, and the control module of the actuator 2 is a second control module. The use status change signal can be determined based on the connection status of the first interface 12 and the second interface 23. The first interface 12 sends the use status change signal to the first control module, and the second interface 23 sends the use status change signal to the second control module.

[0069] In other words, when the first interface 12 and the second interface 23 are connected, it indicates that the setting mechanism 1 and the actuator 2 have been installed. Therefore, the first interface 12 automatically sends the usage status change signal to the first control module, and the second interface 23 automatically sends the usage status change signal to the second control module. This usage status change signal indicates an integrated state. The setting mechanism 1 and the actuator 2 automatically switch from wireless communication to wired communication.

[0070] When the first control module or the second control module detects that the first interface 12 and the second interface 23 are disconnected, indicating that the setting mechanism 1 and the actuator 2 have been separated, the first interface 12 automatically sends the usage status change signal to the first control module, and the second interface 23 sends the usage status change signal to the second control module. This usage status change signal indicates a separation state. Therefore, the setting mechanism 1 and the actuator 2 automatically switch from wired communication to wireless communication.

[0071] Furthermore, in an optional embodiment, the control method further includes:

[0072] S4. After the setting mechanism 1 and the execution mechanism 2 are connected or disconnected by wired communication, the first interface 12 sends the usage status change signal to the first control module, and the second interface 23 sends the usage status change signal to the second control module.

[0073] Furthermore, in an embodiment of the present invention, the first interface 12 of the setting mechanism 1 uses a female plug terminal, and the second interface 23 of the actuator 2 uses a male plug terminal. When the female plug terminal and the male plug terminal are connected, the first control module can use the interface circuit of the setting mechanism 1 and the corresponding interface communication protocol to identify whether the interface terminal is inserted. That is, the first interface 12 sends the usage status change signal to the first control module, and the second interface 23 sends the usage status change signal to the second control module. When it is recognized that an interface terminal is connected, wired communication is established between the setting mechanism 1 and the actuator 2, and the communication between the setting mechanism 1 and the actuator 2 is switched from wireless communication to wired communication.

[0074] Furthermore, if Figure 5 As shown, when the setting mechanism 1 and the actuator 2 are disconnected, the first control module can detect the device's disconnection status through the interface circuit and interface communication protocol of the setting mechanism 1. The first interface 12 sends the usage status change signal to the first control module, and the second interface 23 sends the usage status change signal to the second control module. The setting mechanism 1 and the actuator 2 then switch from wired communication to wireless communication, and the setting mechanism 1 and the actuator 2 communicate wirelessly.

[0075] Furthermore, in an optional embodiment, the first interface 12 and the second interface 23 are pre-stored with a communication protocol, and the control method further includes:

[0076] S5. The first interface 12 sends a wired communication request to the second interface 23 based on the level change signal and the communication protocol, and the second interface 23 agrees to the wired communication request based on the communication protocol to complete the wired communication connection between the setting mechanism 1 and the actuator 2; or, the second interface 23 sends a wired communication request to the first interface 12 based on the level change signal and the communication protocol, and the first interface 12 agrees to the wired communication request based on the communication protocol to complete the wired communication connection between the setting mechanism 1 and the actuator 2.

[0077] Specifically, when the female plug terminal is mated with the male plug terminal, the first control module can use the interface circuit of the setting mechanism 1 and the corresponding interface communication protocol to identify whether the interface terminal is inserted. Generally, when the interface terminal is inserted, the level changes from low to high, and when the interface terminal is removed, the level changes from high to low. Therefore, when the first interface 12 is plugged into the second interface 23, the first control module detects that the level change signal of the first interface 12 changes from low to high. It then controls the first interface 12 to send a wired communication request to the second interface 23 based on the communication protocol. The second interface 23 agrees to the wired communication request based on the communication protocol, thereby completing the wired communication connection between the setting mechanism 1 and the actuator 2.

[0078] Similarly, when the first interface 12 is unplugged from the second interface 23, the first control module detects that the level change signal of the first interface 12 changes from a high level to a low level. Since the wired communication between the first interface 12 and the second interface 23 is ended, the setting mechanism 1 and the execution mechanism 2 can automatically establish a wireless communication connection.

[0079] Furthermore, in an optional embodiment, the matching information is a first identification code and a second identification code, the setting mechanism 1 pre-stores the first identification code, and the executing mechanism 2 pre-stores the second identification code; the first identification code corresponds to the executing mechanism 2, and the second identification code corresponds to the setting mechanism 1. The setting mechanism 1 is controlled to send a wireless connection request to the executing mechanism 2 based on the first identification code, and the executing mechanism 2 responds to the wireless connection request based on the second identification code.

[0080] Specifically, in this embodiment of the present invention, the control unit of setup agency 1 pre-stores the unique identification code of each actuator 2 to facilitate verification and interaction with legitimate actuators 2. Actuators 2 also pre-store the identification code of their corresponding setup agency 1, ensuring they only respond to instructions from authorized setup agencies 1.

[0081] In actual operation, the control unit of the setting mechanism 1 determines which communication method to adopt to communicate with the control unit of the actuator 2 by monitoring the connection status of the interface module of the setting mechanism 1.

[0082] If the first interface 12 of the setting mechanism 1 and the second interface 23 of the actuator 2 are in a connected state, it means that the setting mechanism 1 and the actuator 2 can communicate directly through a physical line. At this time, the two can communicate through their respective interface modules to achieve wired communication and command control.

[0083] When it detects that the first interface 12 of setup mechanism 1 and the second interface 23 of actuator 2 are disconnected, meaning that wired communication is not possible, setup mechanism 1 and the actuator mechanism initiate a wireless connection process. Setup mechanism 1 sends a wireless connection request to the target actuator 2 based on the actuator 2's identification code. This typically involves some form of wireless communication technology, such as Bluetooth, Wi-Fi, or Zigbee. Upon receiving the connection request, actuator 2 verifies it against its internally stored setup mechanism 1 identification code and, upon confirming the validity of the requesting source, agrees to establish the wireless connection.

[0084] This method enables the circuit breaker to flexibly switch communication modes in different environments, ensuring normal operation when wired connections are unavailable, thereby enhancing the stability and reliability of the system.

[0085] Furthermore, in an optional embodiment, when multiple actuators 2 are provided, the setting mechanism 1 pre-stores identification codes for multiple actuators 2. After the setting mechanism 1 is connected to one of the actuators 2, that is, when the setting mechanism 1 and one of the actuators 2 are in an integrated state, the setting mechanism 1 establishes a wired communication connection with the actuator 2, and the setting mechanism 1 establishes a wireless communication connection with other actuators 2 that have not been fully installed. When the setting mechanism 1 is not connected to all actuators 2, that is, when the setting mechanism 1 and all actuators 2 are in a separate state, the setting mechanism 1 establishes a wireless communication connection with all actuators 2.

[0086] like Figure 6 As shown, when multiple actuators 2 are used in combination, the pairing method described above for a single actuator 2 can be used. Once the setup mechanism 1 is connected to one actuator 2, that actuator 2 becomes the master actuator 2. The setup mechanism 1 is then paired with each of the remaining actuators 2, each becoming a slave actuator 2. This completes the wireless communication connection. If the setup mechanism 1 is not yet connected to all actuators 2, direct wireless communication can be used to establish a connection.

[0087] At the same time, the setting mechanism 1 will match a number for each paired actuator 2, making it convenient to view parameters or set operations for the main actuator 2 and each sub-actuator 2 in the combination.

[0088] With such a configuration, since a traditional circuit breaker works in pairs with a single setting mechanism 1 and a single actuator 2, the embodiment of the present invention uses a single setting mechanism 1 to communicate with multiple actuators 2 at the same time, so that the entire working process can be realized only by a single setting mechanism 1, which can significantly reduce the number of setting mechanisms 1 used and, to a certain extent, can reduce production costs and improve product competitiveness.

[0089] Furthermore, in an optional embodiment, the control method further includes:

[0090] S6. Obtain a change signal;

[0091] S7 . Selecting a controlled actuator 2 in communication with the setting mechanism 1 according to the change signal.

[0092] When a technician wishes to change the corresponding setting mechanism 1, they simply input a change signal into the first control module. The first control module then controls the setting mechanism 1 to establish a communication connection with the corresponding actuator 2 based on the change signal. In other words, when a wired connection is established with one actuator 2, wireless communication with that actuator 2 and other actuators 2 can be established based on the change signal. The change signal can be obtained by inputting the change signal via a keystroke or by directly selecting the corresponding actuator code on the main control screen.

[0093] Furthermore, in an optional embodiment, the control method further includes:

[0094] S8, obtaining a current limiting signal; the current limiting signal is used to indicate a change in the current limiting threshold of the actuator 2;

[0095] S9 . Control the setting mechanism 1 to adjust the current limiting threshold of the controlled actuator 2 according to the current limiting signal.

[0096] In this embodiment of the present invention, technicians can adjust the current-limiting threshold based on actual conditions to adjust the tripping current of the circuit breaker. Because the first or second control modules are communicatively connected, technicians can directly change the current-limiting threshold of actuator 2 through the first or second control modules. The change signal can be obtained through key input or by directly selecting the code for the corresponding actuator structure on the main control panel.

[0097] Furthermore, in an optional embodiment, the control method further includes:

[0098] S10, obtaining an opening / closing signal; the opening / closing signal is used to indicate a change in the opening / closing state of the actuator 2;

[0099] S11 . According to the opening / closing signal, control the setting mechanism 1 to perform opening / closing operations on the controlled actuator 2 .

[0100] In this embodiment of the present invention, technicians can adjust the operating state of the circuit breaker based on actual conditions, allowing for flexible adjustment of the circuit breaker's open / close state. Technicians can directly change the open / close state of the actuator 2 through the first or second control module. The change signal can be obtained through key input or by directly selecting the code for the corresponding actuator structure on the main control panel.

[0101] In a second aspect, the present invention further provides a circuit breaker, which applies the circuit breaker control method described in any one of the above embodiments; the circuit breaker includes an actuator 2 and a setting mechanism 1.

[0102] Specifically, in this embodiment of the present invention, actuator 2 is at least used to enable or disable a circuit; actuator 2 is provided with a second communication module 22. A setting mechanism 1 is detachably mounted on actuator 2 and provided with a first communication module. Setting mechanism 1 is at least used to set operating parameters of actuator 2. Wireless communication types may include, but are not limited to, Wi-Fi, Bluetooth, NB-IoT, LoRa, ZigBee, and 433. This embodiment merely illustrates wireless communication types and does not limit them. Those skilled in the art may modify these types based on practical circumstances, as long as they achieve the same technical effect.

[0103] Furthermore, the setting mechanism 1 has an integrated state in which it is mounted on the actuator 2, and a separate state in which it is separated from the actuator 2. When the setting mechanism 1 is in the integrated state, the second communication module 22 is not connected to the first communication module, and the setting mechanism 1 and the actuator 2 communicate with each other by wire. When the setting mechanism 1 is in the separate state, the second communication module 22 is wirelessly connected to the first communication module, and the setting mechanism 1 and the actuator 2 communicate with each other by wireless.

[0104] With such a configuration, the embodiment of the present invention makes the setting mechanism 1 and the actuator 2 detachable. When the setting mechanism 1 is installed on the actuator 2, the setting mechanism 1 and the actuator 2 communicate by wire. When the setting mechanism 1 is removed from the actuator 2, it is directly converted to wireless communication. The technician can thus continue to view the operating parameters of the circuit breaker and set the working conditions of the circuit breaker from the setting mechanism 1. This eliminates the need for the technician to re-operate after installation, thereby improving work efficiency to a certain extent. In addition, after the setting mechanism 1 is removed from the actuator 2, the setting mechanism 1 can be taken to a position away from the actuator 2, and the operating distance can be selected to avoid the strong electric environment around the circuit breaker and avoid the risk of electric shock during the operation process. This makes it convenient for maintenance personnel to maintain the setting mechanism 1. While ensuring the normal operation of the circuit breaker, it can also reduce the safety hazards posed to maintenance personnel by the high voltage of the actuator 2 during live maintenance or operation.

[0105] Furthermore, in an optional embodiment, the setting mechanism 1 is provided with a first interface 12, and the executing mechanism 2 is provided with a second interface 23. If the current connection state is the integrated state, the first interface 12 is connected to the second interface 23, and the setting mechanism 1 and the executing mechanism 2 are controlled to perform wired communication via the first interface 12 and the second interface 23. For details, please refer to the method section and will not be repeated here.

[0106] Furthermore, in an optional embodiment, the actuator 2 is detachably connected to the setting mechanism 1 via a magnetic assembly. The magnetic assembly includes a first magnetic member 11 and a second magnetic member 21. The first magnetic member 11 is disposed in the setting mechanism 1, and the second magnetic member 21 is disposed on the actuator 2, with the second magnetic member 21 being disposed corresponding to the first magnetic member 11.

[0107] Furthermore, in an optional embodiment, the setting mechanism 1 is provided with an operation button 14 , and one or more of the change signal, the current limiting signal and the opening and closing signal are input through the operation button 14 .

[0108] Furthermore, in an optional embodiment, the setting mechanism 1 includes a first control module, a display module, a battery module and a battery management module.

[0109] Specifically, in an embodiment of the present invention, the first control module can be communicatively connected to the operation button 14, and the first control module is simultaneously communicatively connected to the first interface 12 and the first communication module. The display module is communicatively connected to the first control module. The first control module is responsible for transmitting each parameter to the display module for display, and transmitting the parameters set by the operation button 14 to the actuator 2 through the first interface 12. When the setting mechanism 1 is installed on the actuator 2, wired communication and charging are achieved through the first interface 12 and the second interface 23. When separated from the actuator 2, the first control module communicates with the actuator 2 wirelessly.

[0110] In an embodiment of the present invention, the display module includes a display screen 15, which is used at least to view real-time data on electricity consumption, view parameter information, and modify parameters in conjunction with the operation button 14. The battery module is electrically connected to the first control module, and the battery module supplies power to the first control module, which in turn supplies power to the display module and the first communication module. The battery management module is communicatively connected to the battery module. The battery management module has the function of intelligently managing the charge and discharge of the battery module and various protection functions such as short circuit, overcurrent, and overheating of the battery module, which can effectively prevent overcharging, over-discharging, passivation, and damage to the battery module. When direct current from the outside is detected, it can switch to direct current power supply, or automatically switch to battery module power supply after detecting that the external direct current is disconnected.

[0111] In an embodiment of the present invention, the first interface 12 of the setting mechanism 1 uses a female plug terminal, and the second interface 23 of the actuator 2 uses a male plug terminal. When the female plug terminal and the male plug terminal are connected, the first control module can use the interface circuit of the setting mechanism 1 and the corresponding interface communication protocol to identify whether the interface terminal is inserted. When the interface terminal is detected, wired communication is established between the setting mechanism 1 and the actuator 2, and the communication between the setting mechanism 1 and the actuator 2 is switched from wireless communication to wired communication. In addition, the actuator 2 can also provide power to the setting mechanism 1. The setting mechanism 1 is powered by the battery module and then supplied by the direct current provided by the actuator 2. At the same time, the power provided by the actuator 2 also charges the battery.

[0112] Furthermore, if Figure 5 As shown, when the setting mechanism 1 and the actuator 2 are separated, the first control module can detect the device's unplugged state through the interface circuit and interface communication protocol of the setting mechanism 1. Then, the setting mechanism 1 and the actuator 2 switch from wired communication to wireless communication. The setting mechanism 1 and the actuator 2 communicate wirelessly, and the setting mechanism 1 is powered by the battery module instead of the DC power supplied by the actuator 2. When the setting mechanism 1 is used alone, it can be charged using a mobile phone charger. As long as the charging plug is matched with the male plug of the interface of the setting mechanism 1, it can be plugged in for charging.

[0113] Furthermore, the setting mechanism 1 is also provided with an indicator light 13. The indicator light 13 is a multi-color light, which uses different colors and flashing frequencies to indicate the various working states of the setting mechanism 1, such as the pairing state with the actuator 2, with blue slow flashing, fast flashing and constant light indicating unpaired, pairing and paired respectively. For example, red is used to indicate a fault state. When the intelligent circuit breaker needs to interact with an external device through wireless communication, it is achieved through the wireless communication module of the setting mechanism 1. First, the setting mechanism 1 is allowed to perform network configuration operation with the external device, and then enter the external wireless network. The network configuration operation can be performed by selecting the external network configuration combination key through the operation button 14 of the setting mechanism 1. The indicator light 13 of the setting mechanism 1 flashes blue quickly. When the matching is successful, the indicator light 13 of the setting mechanism 1 is displayed in blue and constant light.

[0114] With this arrangement, the embodiment of the present invention can simultaneously realize the functions of communication and charging through the second interface 23 by providing a battery module, so that the first interface 12 and the second interface 23 can provide power and charging while providing communication, integrating different functions, thereby improving the functionality of the first interface 12 and the second interface 23, and facilitating use by technicians. Moreover, during maintenance, that is, when the setting mechanism 1 is separated from the actuator 2, the battery module can ensure the normal operation of the setting mechanism 1. Moreover, since the setting mechanism 1 can achieve wireless communication with the actuator 2, it can be moved over a large range without being limited by the distance of the power cord, thereby facilitating operation by technicians.

[0115] In an optional embodiment, the actuator 2 includes a second control module, an opening and closing module, a sampling module and a metering module.

[0116] Furthermore, in an embodiment of the present invention, the second control module is simultaneously communicatively connected with the second interface 23 and the second communication module 22. The second control module is responsible for the control operation of the entire actuator 2, and obtains various parameters calculated by the metering module for various judgments and controls. For example, according to the analysis of the metering results, fault phenomena such as short circuit, overload, leakage or overtemperature are obtained, and then the opening and closing module is driven to perform disconnection protection. The second control module encapsulates the circuit parameter data information corresponding to the real-time status, fault phenomena and other working conditions into various data packets, and outputs the data packets to the remote terminal device through the second communication module, and also transmits various status information data packets to the setting mechanism 1 through wired or wireless communication, and also receives instructions from the terminal device and the setting mechanism 1 through the communication module. The power supply module is used to connect the input end of the actuator 2, the input end is connected to the AC power line, and the output end of the actuator 2 is used to connect the load.

[0117] Furthermore, in an embodiment of the present invention, the opening and closing module is communicatively connected to the second control module; the opening and closing module is configured to perform opening and closing operations. The opening and closing module includes a trip unit and an electric operation unit. The trip unit is configured to receive instructions from the microcontroller unit to perform circuit breaker opening when the second control module determines that the collected data reaches a protection threshold. The electric operation unit is configured to implement remote control of circuit breaker opening and closing operations.

[0118] Furthermore, in an embodiment of the present invention, a sampling module is communicatively connected to the second control module; the sampling module is at least configured to collect operating parameters of the circuit breaker during operation; the operating parameters include at least current parameters, voltage parameters, leakage parameters, and temperature parameters. The sampling module includes a collection circuit module, a current transformer, a voltage divider, a leakage transformer, and a temperature sensor; the current transformer is configured to detect and collect current data from the circuit breaker; the voltage divider is configured to detect and collect voltage data from the circuit breaker; the leakage transformer is configured to collect leakage data; and the temperature sensor is configured to collect line temperature data. The sampling module converts the various collected data and transmits them to the metering module for processing.

[0119] Furthermore, in an embodiment of the present invention, a metering module is communicatively connected to the sampling module and the second control module; the metering module is configured to transmit the operating parameters to the second control module. The metering module analyzes and calculates the data transmitted by the sampling module to obtain various values, such as voltage, current, leakage current, temperature, and power, and then transmits these values ​​to the second control module for fault diagnosis and processing, such as short circuit, overload, leakage, or overtemperature.

[0120] Furthermore, in an optional embodiment, the actuator 2 further includes a status light 25 and an execution button 24 .

[0121] Specifically, the status light 25 is communicatively connected to the second control module and is used to indicate the operating status of the actuator 2. The status light 25 is multi-colored, using different colors and flashing frequencies to indicate various operating states of the setting mechanism 1. For example, the pairing status with the actuator 2 is indicated by slow flashing blue, fast flashing blue, and a constant light blue indicating unpaired, pairing in progress, and paired, respectively. Alternatively, red indicates a fault state.

[0122] Furthermore, in this embodiment of the present invention, an execution button 24 is communicatively connected to the second control module; the execution button 24 is used to control the operating state of the actuator 2. The execution button 24 adopts a one-button multiplexing mode, where a long press is used to pair with the setting mechanism 1, and a short press is used to manually open or close the circuit breaker.

[0123] Furthermore, in the embodiment of the present invention, the setting mechanism 1 and the execution mechanism 2 execute the working process of the button 24 and the status light 25 during the pairing process.

[0124] When the actuator 2 is powered on, long press the execution button 24, and the status light 25 flashes blue quickly. At this time, operate the operation button 14 of the setting mechanism 1 to select the pairing combination key for pairing, and the setting mechanism 1 indicator light 13 flashes blue quickly. When the pairing is successful, the actuator 2 status light 25 and the setting mechanism 1 indicator light 13 are always blue, and then the setting mechanism 1 and the actuator 2 can exchange data and information through wireless communication.
