[0002] Circuit breakers are widely used in residential, commercial buildings, industrial power distribution systems, and new energy fields to protect circuits from damage caused by overloads, short circuits, and other faults. When the line current exceeds a set value (overload or short circuit), the internal thermomagnetic or electronic tripping mechanism activates, automatically disconnecting the circuit. Some circuit breakers also integrate residual current detection to prevent electric shock or fire risks caused by leakage current, ensuring personal and equipment safety. Utility Model Content

Detailed Implementation

[0020] Embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0021] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0022] In some conventional smart circuit breakers, to enable remote control of the circuit breaker module, an electric operating mechanism can be installed on one side of the module. This mechanism drives the circuit breaker module to perform opening or closing operations based on control signals from remote equipment. Furthermore, to monitor the circuit breaker's operating status (such as operating current, overload current, and leakage current), a separate circuit detection module is required at the circuit breaker's terminals. Conventional smart circuit breakers can only perform one function of either the electric operating mechanism or the circuit detection module, and these two are independently installed, resulting in a dispersed structure and significant space requirements. This can increase the size of the smart circuit breaker, thus affecting its installation convenience and operational flexibility.

[0023] This disclosure provides an electrically operated mechanism and a smart circuit breaker. The electrically operated mechanism includes a housing, a pusher, a drive assembly, and a first detection circuit. The housing includes a first part and a second part. The second part is connected to the first part. The first part can be arranged on one side of the circuit breaker module in a first direction. The second part can be arranged on one side of the circuit breaker module in a second direction perpendicular to the first direction. The pusher can be connected to the operating handle of the circuit breaker module. The drive assembly is at least partially disposed in the first part and connected to the pusher. The drive assembly can push the operating handle of the circuit breaker module between a closed position and an open position via the pusher. The first detection circuit is disposed in the second part. The first detection circuit can be electrically coupled to the terminals of the circuit breaker module to detect the current flowing through the terminals of the circuit breaker module. With this arrangement, the drive assembly of the electrically operated mechanism can be disposed in the first part of the housing and can be used to drive the operating handle of the circuit breaker module, thereby realizing remote control of opening and closing operations. At the same time, the first detection circuit of the electrically operated mechanism is disposed in the second part of the housing and can detect the current flowing through the terminals in real time. The electric operating mechanism integrates remote control and current detection functions, eliminating the need for separate electric operating or detection modules. This reduces size and improves ease of use with circuit breaker modules. The following will combine... Figures 1 to 4 The principles of this disclosure will be described in detail below.

[0024] In this disclosure, the first direction X, the second direction Y, and the third direction Z refer to three mutually perpendicular spatial directions, which can correspond to the three coordinate axes in a Cartesian coordinate system. For example, the first direction X is the horizontal direction, the second direction Y is the vertical direction, and the third direction Z is the vertical direction. It should be noted that these three directions are not limited to the Cartesian coordinate system and can also be applied to other types of coordinate systems. This article uses the Cartesian coordinate system as an example to explain in detail the structure and working principle of the intelligent circuit breaker.

[0025] like Figures 1 to 4As shown, the intelligent circuit breaker may include an electrically operated mechanism 100 and a circuit breaker module 600. As an example, the circuit breaker module 600 may include two circuit breakers 601. Each circuit breaker 601 includes paired terminals 610 located at opposite ends in the second direction Y. One of the two circuit breakers 601 is used to connect to the incoming and outgoing terminals of a phase line, enabling it to perform opening or closing operations on that phase line. The other of the two circuit breakers 601 is used to connect to the incoming and outgoing terminals of the neutral line. As another example, the circuit breaker module 600 may include multiple circuit breakers 601, such as three or four, arranged side-by-side in the first direction X. Each circuit breaker 601 includes paired terminals 610 located at opposite ends in the second direction Y. The paired terminals 610 of each circuit breaker 601 are respectively used to connect to the incoming and outgoing terminals of a circuit line, thereby performing opening or closing operations on the corresponding circuit line.

[0026] In some embodiments, such as Figure 1 and Figure 4 As shown, the circuit breaker module 600 may include a miniature circuit breaker 601. In this manner, the circuit breaker module 600 can provide overload and short-circuit protection for the line. In other embodiments, the circuit breaker module 600 may include at least one of a residual current device (RCD) and a residual current operated circuit breaker 601 with overcurrent protection. Using this arrangement, the circuit breaker module 600 can provide residual current protection and automatically trip upon detection of abnormal current (including overcurrent or residual current), disconnecting the circuit to ensure personal and equipment safety.

[0027] like Figures 1 to 3 As shown, the electric operating mechanism 100 includes a housing 10, a pusher 21, a drive assembly 20, and a first detection circuit. The housing 10 is made of insulating material, which not only provides good insulation but also has a robust structure, preventing external debris and moisture from entering, thereby protecting the internal electronic components. The housing 10 includes a first portion 11 and a second portion 12 that are perpendicularly connected to each other. The second portion 12 is connected to the first portion 11. The first portion 11 has a first receiving cavity, and the second portion 12 has a second receiving cavity. In some embodiments, the first and second receiving cavities are connected. In other embodiments, the first and second receiving cavities are independent of each other, and only necessary wiring holes are provided between the two receiving cavities. The first portion 11 may be arranged on one side of the circuit breaker module 600 in the first direction X. The second portion 12 may be arranged on one side of the circuit breaker module 600 in the second direction Y, which is perpendicular to the first direction X.

[0028] In some embodiments, the circuit breaker module 600 includes a plurality of circuit breakers 601 arranged sequentially in a first direction X. For ease of description of the shape and layout of the electrically operated mechanism 100, the first direction X is taken as a horizontal direction. In this case, the first portion 11 can be arranged on the left or right side of the circuit breaker module 600, and the second portion 12 can be arranged on the top or bottom of the circuit breaker module 600. Therefore, the arrangement of the first portion 11 and the second portion 12 includes at least four possibilities: the first portion 11 is on the left and the second portion 12 is on the top; the first portion 11 is on the right and the second portion 12 is on the top; the first portion 11 is on the left and the second portion 12 is on the bottom; and the first portion 11 is on the right and the second portion 12 is on the bottom.

[0029] As an example, such as Figure 2 and Figure 3 As shown, the first part 11 may include an operation hole 111. The operation hole 111 is located on one side of the first part 11 in a third direction Z, which is perpendicular to the first direction X and the second direction Y. The second part 12 may include wiring holes 121 corresponding to the wiring terminals 610 of the circuit breaker module 600. Here, the number of wiring holes 121 is consistent with the number of wiring terminals 610. The wiring holes 121 correspond to the wiring terminals 610 of the circuit breaker module 600. The wiring holes 121 allow external cables to be inserted for electrical connection with the wiring terminals 610.

[0030] In some embodiments, the circuit breaker module 600 may include two circuit breakers 601. Each circuit breaker 601 has a terminal 610 on the side facing the second portion 12, and the second portion 12 includes two wiring holes 121. As another example, the circuit breaker module 600 may include multiple circuit breakers 601, such as three or four. Each circuit breaker 601 has a terminal 610 on the side facing the second portion 12, and the second portion 12 may include multiple wiring holes 121. The multiple wiring holes 121 correspond one-to-one with the terminal 610 of the multiple circuit breakers 601.

[0031] like Figures 1 to 3As shown, the pusher 21 can be disposed at the operating hole 111. The pusher 21 can extend along the first direction X. The pusher 21 can be connected to the operating handle 640 of the circuit breaker module 600. As an example, a limit groove can be provided on the side of the pusher 21 facing the operating handle 640. The operating handle 640 can be inserted into the limit groove. When the pusher 21 moves, it can push the operating handle 640 to switch between the closed position and the open position. As another example, a connecting part, such as a connecting hole, can be provided on the operating handle 640 of the circuit breaker module 600. The pusher 21 can be a linkage. The linkage can be inserted into the connecting holes of one or more operating handles 640, thereby enabling one or more circuit breakers 601 to perform opening and closing operations simultaneously. It should be understood that the movement of the operating handle 640 is rotational, therefore a rotational connection must also be maintained between the pusher 21 and the operating handle 640.

[0032] like Figures 1 to 3 As shown, the drive assembly 20 is at least partially disposed within the first portion 11 and connected to the pusher 21. As an example, the drive assembly 20 may include a drive motor, a gear assembly, and a swing arm. The gear assembly is connected to the drive motor and the swing arm. When the drive motor rotates, it drives the swing arm to move. The drive motor and gear assembly may be disposed within the first portion 11. The swing arm may be disposed at the operating hole 111 and connected to the pusher 21. When the drive motor receives a control signal, it can rotate clockwise or counterclockwise, thereby driving the pusher 21 to move. With this arrangement, the drive assembly 20 can push the operating handle 640 of the circuit breaker module 600 between the closed and open positions via the pusher 21.

[0033] like Figure 2 As shown, the first detection circuit is disposed within the second part 12 and can be electrically coupled to the terminal 610 of the circuit breaker module 600. The first detection circuit can detect the current flowing through the terminal 610 of the circuit breaker module 600. As an example, the first detection circuit can be a circuit board. The required detection lines and detection elements can be arranged on the circuit board.

[0034] With this arrangement, the drive assembly 20 of the electric operating mechanism 100 is located in the first part 11 of the housing 10, and can be used to drive the operating handle 640 of the circuit breaker module 600 to achieve remote opening and closing. The first detection circuit of the electric operating mechanism 100 is located in the second part 12 of the housing 10, and can detect the current flowing through the terminal 610 in real time. The electric operating mechanism 100 can integrate remote control function and current detection function, eliminating the need for additional independent operation or detection modules, reducing size, and thus improving convenience when used with the circuit breaker module 600.

[0035] In some embodiments, such as Figure 2 As shown, the electric operating mechanism 100 also includes an electrical connection piece 30. The electrical connection piece 30 can be disposed within the wiring hole 121. The electrical connection piece 30 is electrically connected to the first detection circuit and can also be electrically connected to the wiring terminal 610 of the circuit breaker module 600. In this way, the first detection circuit can detect the current flowing through the wiring terminal 610 of the circuit breaker module 600 in a contact manner via the electrical connection piece 30. As an example, the number of electrical connection pieces 30 is consistent with the number of wiring holes 121.

[0036] In some embodiments, the first detection circuit further includes other types of detection components. These detection components can also be used to detect the current flowing through the terminals 610 of the circuit breaker module 600. As examples, the detection components may include current transformers, Rogowski coils, or printed coils, etc., and this disclosure is not intended to limit them. In some embodiments, the detection components may be based on the principle of electromagnetic induction, sensing the magnetic field generated by the alternating current in the conductor, thereby outputting a signal proportional to the primary current in the secondary coil, thereby achieving non-contact monitoring of the circuit current. In other embodiments, high-frequency noise, irregular pulses, and other arc characteristics in the current waveform can also be captured for identifying dangerous arc faults.

[0037] In some embodiments, such as Figures 1 to 3 As shown, the electric operating mechanism 100 also includes a connector 40. The connector 40 is connected to the housing 10 and is adapted to be detachably connected to the circuit breaker module 600. In this way, the electric operating mechanism 100 can be quickly installed and removed from the circuit breaker module 600, which helps to improve the convenience of use.

[0038] As an example, such as Figures 1 to 3 As shown, the first portion 11 also includes a first through hole 113 extending along a first direction X. The connector 40 includes a first connector 41. The first connector 41 passes through the first through hole 113 and is adapted to engage with the circuit breaker module 600. For example, two first through holes 113 are provided on the first portion 11. The two first connectors 41 are respectively inserted into the corresponding first through holes 113. The length of the first connector 41 is greater than the thickness of the first portion 11 in the first direction X. The circuit breaker module 600 may also include two insertion holes. The two insertion holes correspond to the corresponding first through holes 113 in the two first through holes 113. Therefore, after passing through the first through hole 113, the first connector 41 can also engage with the insertion holes of the circuit breaker module 600. As an example, the first connector 41 can be a rivet. The length of the rivet can be set as needed. When the circuit breaker module 600 includes multiple circuit breakers 601, the rivet can also be connected to multiple circuit breakers 601.

[0039] It should be noted that the figures, values, etc., mentioned above and elsewhere in this disclosure are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable figures or values ​​are possible.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, connector 40 also includes a second connector 42. The second connector 42 is disposed on the side of the second portion 12 facing the circuit breaker module 600 and is adapted to engage with the circuit breaker module 600 via a snap-fit. As an example, the second connector 42 can be a snap-fit. A slot can be provided on the circuit breaker module 600 corresponding to the position of the snap-fit. When the circuit breaker module 600 abuts against the first portion 11 and the second portion 12, the snap-fit ​​can be inserted into the slot, thereby limiting the circuit breaker module 600 and the electric operating mechanism 100.

[0041] In some embodiments, such as Figure 2 and Figure 4 As shown, the first part 11 also includes a second through hole 114. The second through hole 114 is disposed on the side of the first part 11 facing the circuit breaker module 600. The electric operating mechanism 100 also includes signal lines and control circuitry. The circuit breaker module 600 includes a third through hole 630. The third through hole 630 is disposed on the side of the circuit breaker module 600 facing the first part 11. A second detection circuit is disposed within the circuit breaker module 600. As an example, when the circuit breaker module 600 includes multiple circuit breakers 601, a second detection circuit can be disposed within each circuit breaker 601.

[0042] As an example, the second detection circuit can be a leakage current detection circuit. The second detection circuit can generate a leakage current signal upon detecting a leakage current in a circuit electrically connected to the circuit breaker module 600. A signal line passes through the second through-hole 114 and the third through-hole 630. For example, the signal line can be a flexible circuit board or other type of flexible wiring. The signal line can be electrically connected to the second detection circuit of the circuit breaker module 600. A control circuit is disposed within the first part 11. The control circuit is electrically connected to the signal line. The control circuit can trip the circuit breaker module 600 based on the leakage current signal from the second detection circuit.

[0043] With this arrangement, when a leakage current occurs in the circuit electrically connected to the circuit breaker module 600, the second detection circuit within the circuit breaker module 600 can send the detected leakage current signal to the control circuit. Upon receiving the corresponding leakage current signal, the control circuit sends a control signal to the second detection circuit to trip the circuit breaker module 600. Upon receiving this control signal, the second detection circuit unlocks the magnetic tripping mechanism or other type of tripping mechanism.

[0044] In some embodiments, when a short circuit or overload is detected in the circuit, the magnetic tripping mechanism and the thermal tripping mechanism in the circuit breaker module 600 can be directly unlocked.

[0045] In some embodiments, such as Figure 1 and Figure 3 As shown, the electric operating mechanism 100 also includes a communication unit 50. As an example, the communication unit 50 may be a network communication interface. The network communication interface may be mounted on the housing 10. The communication unit 50 is electrically connected to the control circuit and the first detection circuit, and is adapted to communicate with external devices. With this arrangement, the electric operating mechanism 100 can receive indication signals from external devices, thereby enabling the circuit breaker module 600 to perform opening and closing operations. Furthermore, the electric operating mechanism 100 can also send detected operating current, overload current, leakage current, arc monitoring, and other information to external devices via the communication unit 50.

[0046] It should be understood that in other embodiments, the communication unit 50 may also be a wireless communication module, such as Bluetooth, WiFi, etc. The communication unit 50 may be disposed within the first part 11 or the second part 12 of the housing 10. The communication unit 50 may communicate wirelessly with external devices. Those skilled in the art can make the selection as needed, and this disclosure is not intended to limit this.

[0047] As an example, the first detection circuit and the control circuit can be integrated together. As another example, the first detection circuit and the control circuit can be separate circuits, which can be connected by a circuit.

[0048] This disclosure also provides an intelligent circuit breaker. For example... Figure 1 As shown, the intelligent circuit breaker includes any of the above-described electric operating mechanisms 100 and a circuit breaker module 600. The circuit breaker module 600 is disposed on one side of the first part 11 in the first direction X, and abuts against the first part 11 and the second part 12.

[0049] like Figure 1 As shown, the pusher 21 of the electric operating mechanism 100 can be connected to the operating handle 640 of the circuit breaker module 600. When the pusher 21 moves, it can push the operating handle 640 to switch between the closed and open positions. The drive motor of the electric operating mechanism 100 can rotate clockwise or counterclockwise when it receives a control signal, thereby driving the pusher 21 to move. The drive assembly 20 can push the operating handle 640 of the circuit breaker module 600 to switch between the closed and open positions via the pusher 21. The first detection circuit of the electric operating mechanism 100 can detect the current flowing through the terminals 610 of the circuit breaker module 600.

[0050] With this arrangement, the drive assembly 20 of the electric operating mechanism 100 can be located at the first part 11 of the housing 10, and can be used to drive the operating handle 640 of the circuit breaker module 600 to achieve remote opening and closing. The first detection circuit of the electric operating mechanism 100 is located at the second part 12 of the housing 10, and can detect the current flowing through the terminal 610 in real time. When the circuit breaker module 600 is against the first part 11 and the second part 12 of the electric operating mechanism 100, the electric operating mechanism 100 can realize remote control function and current detection function. The intelligent circuit breaker does not require an additional independent operating module or detection module, which can reduce its size.

[0051] In some embodiments, such as Figures 1 to 4 As shown, the circuit breaker module 600 includes a plurality of circuit breakers 601. Each circuit breaker 601 includes a sub-terminal 611 facing the second portion 12. The second portion 12 includes a plurality of sub-wiring holes 1211. The plurality of sub-wiring holes 1211 correspond one-to-one with the sub-terminals 611 of the plurality of circuit breakers 601. As an example, the circuit breaker module 600 may include two circuit breakers 601. If each circuit breaker 601 has a sub-terminal 611 on the side facing the second portion 12, then the second portion 12 includes two sub-wiring holes 1211. As another example, the circuit breaker module 600 includes a plurality of circuit breakers 601, such as three or four, etc. If each circuit breaker 601 has a sub-terminal 611 on the side facing the second portion 12, then the second portion 12 includes a plurality of sub-wiring holes 1211. The plurality of wiring holes 121 correspond to the sub-terminals 611 of the respective circuit breaker 601.

[0052] In some embodiments, such as Figure 2 and Figure 4 As shown, the circuit breaker module 600 includes a positioning portion 620 facing the first portion 11. The first portion 11 also includes a mating portion 112 facing the circuit breaker module 600. The positioning portion 620 is connected to the mating portion 112 and can limit the circuit breaker module 600 and the first portion 11. As an example, the positioning portion 620 can be a groove, and the mating portion 112 can be a protrusion. As another example, the positioning portion 620 can be a protrusion, and the mating portion 112 can be a groove. When the circuit breaker module 600 abuts against the first portion 11 and the second portion 12, the protrusion can be inserted into the groove, thereby limiting the circuit breaker module 600 and the electric operating mechanism 100, which helps to improve the structural stability of the smart circuit breaker.

[0053] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
