Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to an intelligent control module for a circuit breaker. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Furthermore, it generally does not require replacement of components after interrupting a fault current, leading to its widespread application.

[0003] With the rapid development of the Internet of Things (IoT), especially the formation and launch of the "ubiquitous power IoT" concept, there has been a surge in demand for intelligent circuit breakers. As a result, many low-voltage electrical appliance companies have accelerated the development of intelligent circuit breakers, and various intelligent circuit breaker products are constantly emerging. However, the circuit breakers currently used in urban power grids, industrial and mining enterprises, and ordinary household power grids are still non-intelligent circuit breakers, remaining at the stage of "dumb devices."

[0004] Most intelligent circuit breakers on the market are currently designed as a single unit, meaning that the intelligent control module and the circuit opening and closing structure are integrated. When upgrading a circuit to be intelligent, the existing circuit breaker must be removed and a new intelligent circuit breaker installed. This renders the existing circuit breaker unusable, which not only prolongs the construction time of the circuit upgrade but also increases the cost of the intelligent circuit upgrade. Utility Model Content

[0005] The main objective of this application is to provide an intelligent control module for circuit breakers, which aims to improve the problem that existing circuit breakers can only be removed and cannot be used again when the circuit is upgraded to be intelligent.

[0006] To achieve the above objectives, this application proposes an intelligent control module for a circuit breaker, applied in a circuit breaker. The circuit breaker has an input terminal, an output terminal, and a triggering mechanism. The intelligent control module includes a housing assembly, a control assembly, and an operating assembly; wherein...

[0007] The housing assembly is provided with a mounting position for detachably mounting the circuit breaker;

[0008] The operating component is installed on the housing assembly and electrically connected to the control component. The operating component is also drively connected to the triggering mechanism when the circuit breaker is connected to the housing assembly.

[0009] The control component is installed on the housing assembly. When the circuit breaker is connected to the housing assembly, the control component is also electrically connected to the input terminal and the output terminal respectively to collect the electrical parameters of the circuit and control the operation of the operating component according to the electrical parameters to drive the triggering mechanism to perform a tripping operation on the circuit breaker.

[0010] In some embodiments of this application, the housing assembly includes a main body and two connecting arms. The two connecting arms are respectively connected to one side of the main body and extend in a direction perpendicular to the main body away from the main body. The two connecting arms and the main body together form the mounting position.

[0011] In some embodiments of this application, each of the connecting arms is recessed on one side facing the other connecting arm, and the guide groove extends along the length direction of the connecting arm. The guide groove is used to slide with the positioning rib of the circuit breaker.

[0012] In some embodiments of this application, each of the connecting arms has a buckle protruding at one end away from the main body, and the buckle engages with the side of the circuit breaker away from the main body when the circuit breaker is connected to the housing assembly.

[0013] In some embodiments of this application, the main body is provided with a positioning protrusion, which is used to engage with the positioning recess of the circuit breaker.

[0014] In some embodiments of this application, the intelligent control module further includes a first connector and a second connector. When the circuit breaker is connected to the housing assembly, the first connector and the second connector are electrically connected to the input terminal and the output terminal, respectively. The control component is electrically connected to the first connector and the second connector, respectively, to acquire the electrical parameters of the circuit through the first connector and the second connector.

[0015] In some embodiments of this application, the first connector is mounted to a connecting arm by a screw structure and is disposed corresponding to the input end. When the screw structure is rotated in a first direction, the first connector moves toward the input end, and when the screw structure is rotated in a second direction, it moves away from the input end.

[0016] The second connector is mounted to the other connector arm by a screw structure and is positioned corresponding to the output end. When the screw structure is rotated in the first direction, the second connector moves toward the output end, and when the screw structure is rotated in the second direction, it moves away from the output end.

[0017] In some embodiments of this application, the intelligent control module further includes a communicator for communicating with an external intelligent device to receive control commands from the external intelligent device. The control component is electrically connected to the communicator and controls the operation of the operating component according to the control commands received by the communicator to drive the triggering mechanism to perform a tripping operation on the circuit breaker.

[0018] In some embodiments of this application, the operating component includes a drive element and a lever. The drive element is fixedly mounted on the housing assembly and is drivenly connected to the triggering mechanism via the lever. The drive element is also electrically connected to the control component.

[0019] In some embodiments of this application, one end of the lever is provided with a driving end, which is connected to the triggering mechanism in a transmission manner, and the other end of the lever is provided with a linkage part, which is used to connect with the lever of another operating component.

[0020] The intelligent control module for the circuit breaker provided in this application, through the aforementioned structural design, allows for the detachable installation of the intelligent control module onto an existing circuit breaker via a mounting position during intelligent circuit upgrades. When the circuit breaker is connected to the housing assembly, the control component is electrically connected to both the input and output terminals to collect electrical parameters of the circuit. Based on these parameters, the control component determines whether an abnormality has occurred. If an abnormality is detected, the control component controls the operation of the operating component to drive the trigger mechanism to trip the circuit breaker, thereby achieving intelligent circuit upgrades. As can be seen, the technical solution of this application allows the intelligent control module to be installed onto an existing circuit breaker via a mounting position, enabling intelligent upgrades of the existing circuit breaker. This allows the existing circuit breaker to continue to be used, reducing the cost of intelligent circuit upgrades and eliminating the need to disassemble the existing circuit breaker or install a new one, significantly shortening construction time.

[0033] This application provides an intelligent control module 100 for a circuit breaker 200, which is applied to the circuit breaker 200 in a circuit. The intelligent control module 100 can be directly installed on an existing circuit breaker 200 to achieve intelligent transformation of the circuit. It should be emphasized that the circuit breaker 200 has an input terminal, an output terminal, and a triggering mechanism. The input terminal and output terminal are respectively used to connect to cables to connect the circuit breaker 200 in series in the circuit. The triggering mechanism is a key component responsible for quickly disconnecting the circuit when an abnormality (such as overload or short circuit) is detected; it can also disconnect the circuit under external force.

[0034] Please refer to the reference. Figures 1 to 4 In this embodiment, the intelligent control module 100 includes a housing assembly 10, a control assembly 20, and an operation assembly 30. The housing assembly 10 has a mounting position 13 for detachably mounting the circuit breaker 200. The operation assembly 30 is mounted on the housing assembly 10 and electrically connected to the control assembly 20. When the circuit breaker 200 is connected to the housing assembly 10, the operation assembly 30 is also connected to a triggering mechanism. The control assembly 20 is mounted on the housing assembly 10. When the circuit breaker 200 is connected to the housing assembly 10, the control assembly 20 is also electrically connected to both its input and output terminals to collect electrical parameters of the circuit. Based on these electrical parameters, the control assembly 30 is used to drive the triggering mechanism to trip the circuit breaker 200.

[0035] The housing assembly 10 is typically made of plastic and usually includes multiple components. Figure 3 In the example shown, the housing assembly 10 mainly includes a bottom shell 14 and a cover plate 15. The bottom shell 14 is provided with a receiving groove, and the cover plate 15 is connected to the bottom shell 14 to cover and form a receiving cavity. This receiving cavity is used for the installation of other components of the intelligent control module 100. In this way, the housing assembly 10 can provide a stable installation environment for other components of the intelligent control module 100, and can also form a protective enclosure for other components.

[0036] It is understood that the mounting position 13 for detachable installation of circuit breaker 200 means that the housing assembly 10 can detachably install the intelligent control module 100 onto the existing circuit breaker 200 in the circuit through the mounting position 13, without the need for other structures for fixation.

[0037] The control component 20 typically integrates multiple different types of detectors to detect and analyze the collected electrical parameters to determine whether there are any abnormalities in the circuit. These abnormalities include, but are not limited to, undervoltage, overvoltage, and short circuit. It should be noted that the control component 20 can maintain normal operation by collecting electrical energy from the circuit or by using a battery built into the intelligent control module 100.

[0038] When the intelligent control module 100 is applied to the circuit breaker 200 in the circuit, if an abnormal situation occurs in the circuit where the circuit breaker 200 is located, the control component 20 can determine the abnormal situation of the circuit by collecting electrical parameters, and then control the operation component 30 to work. When the operation component 30 is working, it can drive the trigger mechanism. The trigger mechanism is subjected to the force of the operation component 30 and can quickly disconnect the circuit, that is, the circuit breaker 200 is tripped.

[0039] It should be emphasized that both the input and output terminals typically have live wire and neutral wire interfaces, and the control component 20 is usually electrically connected to the live wire and neutral wire interfaces of the input terminal and the live wire and neutral wire interfaces of the output terminal, respectively.

[0040] The intelligent control module 100 of the circuit breaker 200 provided in this application embodiment, through the above-described structural configuration, allows for the intelligent transformation of the circuit. The intelligent control module 100 can be detachably installed on the existing circuit breaker 200 via the mounting position 13. When the circuit breaker 200 is connected to the housing assembly 10, the control component 20 is electrically connected to both the input and output terminals to collect electrical parameters of the circuit. Based on these parameters, it determines whether an abnormality has occurred in the circuit. If an abnormality occurs, the control component 20 controls the operation of the operation component 30 to drive the triggering mechanism to trip the circuit breaker 200, thereby achieving intelligent transformation of the circuit. As can be seen, the technical solution of this application allows the intelligent control module 100 to be installed on the existing circuit breaker 200 in the circuit through the installation position 13, and the intelligent transformation of the existing circuit breaker 200 can be realized through the control component 20. In this way, the existing circuit breaker 200 can still be used, reducing the cost of intelligent transformation of the circuit, and does not involve the disassembly of the existing circuit breaker 200 and the installation of a new circuit breaker 200, which greatly shortens the construction time.

[0041] In some examples, such as Figure 1 and Figure 2As shown, the housing assembly 10 includes a main body 11 and two connecting arms 12. The two connecting arms 12 are respectively connected to one side of the main body 11 and extend in a direction perpendicular to the main body 11 toward a direction away from the main body 11. The two connecting arms 12 and the main body 11 together form a mounting position 13.

[0042] This configuration aims to secure the intelligent control module 100 to the existing circuit breaker 200 by tightly holding the main body 11 and the two connecting arms 12 around the periphery of the existing circuit breaker 200, thereby improving the stability of the intelligent circuit breaker 200.

[0043] It should be noted that most circuit breakers 200 currently on the market and in use are equipped with positioning ribs 201.

[0044] In some examples, such as Figure 1 and Figure 2 As shown, each connecting arm 12 has a guide groove 121 recessed on one side facing the other connecting arm 12, and the guide groove 121 extends along the length direction of the connecting arm 12. The guide groove 121 is used to slide with the positioning rib 201 of the circuit breaker 200.

[0045] With this configuration, the intelligent control module 100 can be installed or removed from the existing circuit breaker 200 by plugging it in. The guide groove 121 slides with the positioning rib 201 of the circuit breaker 200, which can play a guiding role during installation or removal, so as to facilitate the installation or removal of the intelligent control module 100.

[0046] In some examples, such as Figure 1 and Figure 2 As shown, each connecting arm 12 has a protruding latch 122 at the end away from the main body 11. When the circuit breaker 200 is connected to the housing assembly 10, the latch 122 engages with the side of the circuit breaker 200 away from the main body 11. With this configuration, when the intelligent control module 100 is installed in place, the engagement of the latch 122 with the circuit breaker 200 can prevent the circuit breaker 200 from disengaging, improve the reliability of the intelligent control module 100, and also serve as a tactile indication that the intelligent control module 100 is installed in place.

[0047] It should be noted that most circuit breakers 200 currently on the market and in use have a positioning recess.

[0048] In some examples, such as Figure 1 and Figure 2 As shown, the main body 11 has a positioning protrusion 111, which is used to engage with the positioning recess of the circuit breaker 200. This design aims to further improve the reliability of the intelligent control module 100.

[0049] In some examples, each connecting arm 12 has a receiving portion protruding on one side facing the other connecting arm 12. This receiving portion is adapted to fit the outer contour of the circuit breaker 200 so that the connecting arm 12 is in close contact with the outer surface of the circuit breaker 200, thereby improving the reliability of the intelligent control module 100.

[0050] In some examples, such as Figures 1 to 3 As shown, the intelligent control module 100 also includes a first connector 40 and a second connector 50. When the circuit breaker 200 is connected to the housing assembly 10, the first connector 40 and the second connector 50 are electrically connected to the input terminal and the output terminal, respectively. The control assembly 20 is electrically connected to the first connector 40 and the second connector 50, respectively, so as to collect the electrical parameters of the circuit through the first connector 40 and the second connector 50.

[0051] This configuration is intended to facilitate the electrical connection of the control component 20 to the input and output terminals via the first connector 40 and the second connector 50 when the circuit breaker 200 is connected to the housing assembly 10, thereby improving the installation efficiency of the intelligent control module 100.

[0052] In some examples, the control component 20 can also obtain electrical energy from the circuit through the first connector 40 and the second connector 50 to maintain the normal operation of the intelligent control module 100.

[0053] In some examples, such as Figures 1 to 3 As shown, the first connector 40 is mounted to a connecting arm 12 via a screw structure and is positioned corresponding to the input end. When the screw structure is rotated in a first direction, the first connector 40 moves closer to the input end; when the screw structure is rotated in a second direction, it moves away from the input end. The second connector 50 is mounted to another connecting arm 12 via a screw structure and is positioned corresponding to the output end. When the screw structure is rotated in a first direction, the second connector 50 moves closer to the output end; when the screw structure is rotated in a second direction, it moves away from the output end.

[0054] It is understandable that when the first direction is counterclockwise, the second direction is clockwise, and when the first direction is clockwise, the second direction is counterclockwise; that is, the first and second directions are opposite to each other.

[0055] This configuration is designed to facilitate the adjustment of the first connector 40, enabling it to quickly establish a stable and reliable electrical connection with the input terminal, and to facilitate the adjustment of the second connector 50, enabling it to quickly establish a stable and reliable electrical connection with the output terminal.

[0056] Considering that, in some examples, such as Figure 5As shown, the connecting arm 12 equipped with the first connector 40 needs to be equipped with the current detection coil 21 of the control component 20 so that the live wire passes through the current detection coil 21 of the control component 20 and is connected to the live wire interface of the output end. For this purpose, the first connector 40 is preferably a split two-electrode plate, and the electrode plate is provided with a clearance part to avoid the current detection coil, so that the two connecting arms are similar in size.

[0057] In some examples, both connecting arms 12 are fixedly provided with mounting bases 123 for mounting the first connecting member 40 and the second connecting member 50, respectively.

[0058] In some examples, such as Figure 3 As shown, the intelligent control module 100 also includes a communicator for communicating with external intelligent devices to receive control commands from the external intelligent devices. The control component 20 is electrically connected to the communicator and controls the operation component 30 according to the control commands received by the communicator to drive the triggering mechanism to perform a tripping operation on the circuit breaker 200.

[0059] This setup is designed to allow staff to use external smart devices to control the smart control module 100, thereby remotely controlling the circuit breaker 200 and further enhancing the intelligence of the circuit breaker 200.

[0060] In some examples, the communicator can also transmit various parameters of the intelligent control module 100 to external intelligent devices so that staff can monitor the circuit breaker 200 using the external intelligent devices.

[0061] In some examples, such as Figures 1 to 4 As shown, the operating component 30 includes a drive element 31 and a lever 32. The drive element 31 is fixedly mounted on the housing component 10 and is connected to the triggering mechanism via the lever 32. The drive element 31 is also electrically connected to the control component 20. The drive element 31 includes, but is not limited to, a solenoid driver.

[0062] This configuration is designed to enable the drive unit 31 to quickly respond to the control of the control component 20, allowing the drive unit 31 to quickly drive the lever 32 to act on the triggering mechanism, thereby quickly opening the circuit breaker.

[0063] It should be noted that in electrical equipment, devices such as shunt trip units and residual current devices (RCDs) are equipped with operating components 30. In some examples, such as... Figure 4 As shown, one end of the lever 32 is provided with a drive end 321, which is connected to the triggering mechanism for transmission. The other end of the lever 32 is provided with a linkage part 322, which is used to connect with the lever 32 of another operating component 30.

[0064] With this configuration, power devices such as shunt trip units and residual current devices can also be installed on the side of the intelligent control module 100 away from the circuit breaker 200. When the shunt trip unit receives a shunt trip signal, the operating component 30 will drive the triggering mechanism to perform a tripping operation on the circuit breaker 200. When the residual current device receives a leakage current signal, the operating component 30 will drive the triggering mechanism to perform a tripping operation on the circuit breaker 200.

[0065] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
