[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing for a specified time to carry and interrupt current under abnormal circuit conditions. Circuit breakers can be used in various circuits across multiple fields, such as selectively interrupting current flowing into or out of energy storage devices to protect electric vehicle battery packs and new energy charging stations.

[0003] Regarding circuit breakers, the most widely used type on the market is the fuse circuit breaker, which achieves power outage protection by causing the circuit breaker to melt through a control system. However, fuse circuit breakers have the following shortcomings: 1) The melting speed of fuse circuit breakers is relatively slow, resulting in insufficient response time and making them unsuitable for high-precision products. 2) After a certain period of operation, the electrical performance of the circuit breaker will inevitably change, but existing circuit breakers cannot detect their own electrical performance, thus posing a significant safety hazard.

[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Please see the appendix Figure 1 To be continued Figure 8As shown, this embodiment 1 provides a multi-channel intelligent circuit breaker, which includes a housing 1, a conductive bridge 2, an ignition device 3, and an intelligent sensing control module 4. The conductive bridge 2 passes through the housing 1, and a disconnection slot 20 is provided on the conductive bridge 2 at a preset position in the housing 1. The ignition device 3 and the intelligent sensing control module 4 are both built into the housing 1, and the ignition device 3 abuts against the disconnection slot 20. The intelligent sensing control module 4 can sense the operating parameters of the conductive bridge 2 in real time and control the ignition device 3 to disconnect or connect to the power supply accordingly. The operating parameters include at least one of the following: operating current, ambient temperature, and ambient air pressure. As described above, when the circuit breaker is applied to a circuit system, its working principle is as follows: the intelligent sensing control module 4 senses the operating parameters of the conductive bridge 2 in real time (such as the operating current, ambient temperature, and ambient air pressure mentioned above), and analyzes and judges the sensed operating parameters: if all operating parameters fall within the preset threshold range, the operating state of the conductive bridge 2 is determined to be normal; if one or more operating parameters are not within the preset threshold range, the operating state of the conductive bridge 2 is determined to be abnormal. Simultaneously, the intelligent sensing control module 4 also controls the ignition device 3 to operate accordingly based on the judgment result, specifically: ① when the intelligent sensing control module 4 determines that the operating state of the conductive bridge 2 is normal, the intelligent sensing control module 4 controls the ignition device 3 to remain disconnected from the power supply; ② when the intelligent sensing control module 4 determines that the operating state of the conductive bridge 2 is abnormal, the intelligent sensing control module 4 controls the ignition device 3 to be connected to the power supply. Upon energization, the igniter 3 explodes, rapidly disconnecting the disconnecting slot 20 within 2ms (i.e., breaking the conductive bridge 2), thus achieving the purpose of cutting off the current and protecting the circuit system. Understandably, the circuit breaker provided in this embodiment not only responds promptly but also intelligently, sensitively, and comprehensively senses its own electrical performance / operating parameters, thereby greatly improving the safety and reliability of the circuit breaker and even the entire circuit system during operation.

[0034] The following provides a detailed description of the specific structure of the multi-channel intelligent circuit breaker described in this embodiment.

[0035] First, regarding the outer shell 1 and its contents.

[0036] In this embodiment, the preferred implementation structure of the outer shell 1 is as follows: Please refer to the appendix. Figure 1 To be continued Figure 3 and appendices Figure 7As shown, the outer shell 1 includes a first outer shell 11 and a second outer shell 12, both having hollow inner cavities. The first outer shell 11 and the second outer shell 12 can be detachably connected. The first outer shell 11 has a first receiving cavity 111 for the ignition device 3 to be tightly inserted and a second receiving cavity 112 for the intelligent sensing control module 4 (that is, the inner cavity of the first outer shell 11 can be divided into at least the first receiving cavity 111 and the second receiving cavity 112). The second outer shell 12 has an arc extinguishing structure (not shown in the figure) for extinguishing the arc generated by the cut conductive bridge 2, a pressure relief cavity 5 covered by the arc extinguishing structure for depressurizing the high-pressure gas generated by the explosion of the ignition device 3, and a filter pad disposed outside the pressure relief cavity 5 for adsorbing fine particles generated by the explosion.

[0037] Furthermore, based on the connection method between the first outer shell 11 and the second outer shell 12, and the structure of the conductive bridge 2 (generally, the conductive bridge 2 is a long strip), the conductive bridge 2 is sandwiched between the first outer shell 11 and the second outer shell 12, and the specific sandwiching method is as follows: Please refer to the appendix. Figure 2 As shown, if the first outer shell 11 is defined as being above the second outer shell 12, in this embodiment, grooves 13 are respectively recessed upwards on opposite sides of the lower side of the first outer shell 11, and grooves 13 are respectively recessed downwards on opposite sides of the upper side of the second outer shell 12. The grooves 13 on the first outer shell 11 and the second outer shell 12 are arranged opposite to each other, meaning that the grooves 13 on the first outer shell 11 and the second outer shell 12 can engage to accommodate and confine the conductive bridge 2. During assembly, the conductive bridge 2 can be placed in the grooves 13 on the second outer shell 12 firstly, and then the first outer shell 11 and the second outer shell 12 can be engaged and fixed with screws. At that time, the grooves 13 on the first outer shell 11 and the second outer shell 12 will engage to accommodate and confine the conductive bridge 2.

[0038] Furthermore, this embodiment also provides a positioning structure between the conductive bridge 2 and the second housing 12 for positioning and connection, so as to further improve the stability of the conductive bridge 2. The preferred embodiment of the positioning structure is as follows: Please refer to the appendix. Figure 2 and attached Figure 5 As shown, the positioning structure includes a groove 23 integrally recessed on the edge of the conductive bridge 2 and a protrusion 120 integrally protruding on the second outer shell 12 (specifically the clamping groove 13) and positioned and inserted into the groove 23.

[0039] Furthermore, in this embodiment, the first receiving cavity 111 is connected to the second receiving cavity 112 to facilitate the connection and assembly of the ignition device 3 and the intelligent sensing control module 4; and the side of the first receiving cavity 111 facing away from the second receiving cavity 112 is open so that one end of the ignition device 3 extends out of the first receiving cavity 111 and abuts against the disconnect groove 20 on the conductive bridge 2.

[0040] Furthermore, in this embodiment, a plurality of protruding ribs 1120 are integrally provided on the inner wall of the second receiving cavity 112, so that the intelligent sensing control module 4 can be conveniently installed into the second receiving cavity 112, while also limiting the position of the intelligent sensing control module 4.

[0041] Furthermore, the arc-extinguishing structure adopts a block structure made of ceramic or insulating resin material. The arc-extinguishing structure is positioned on the inner bottom surface of the inner cavity of the second outer shell 12. In order to better extinguish the arc, this embodiment also designs the surface of the arc-extinguishing structure facing the first outer shell 11 as a concave arc surface.

[0042] The pressure relief chamber 5 is a hollow structure with openings on the top and bottom sides and opposite vertical sides, and is positioned inside the second outer shell 12; specifically, a vertical partition 50 is also fixedly installed inside the pressure relief chamber 5 (see attached drawing). Figure 7 As shown in the figure, this is to further enhance the arc extinguishing effect. The filter pad is preferably a U-shaped body made of filter cotton, which covers the lower opening side and the two opposite opening sides of the pressure relief chamber 5 to prevent fine particles generated by the explosion from flying out to the outside.

[0043] Next, regarding the conductive bridge 2.

[0044] Please continue to refer to the appendix. Figure 2 Appendix Figure 4 To be continued Figure 6 As shown, based on the elongated shape of the conductive bridge 2, this embodiment preferably has at least two disconnecting slots 20 arranged side-by-side along its length on the conductive bridge 2, with the openings of each pair of adjacent disconnecting slots 20 opening onto opposite surfaces of the conductive bridge 2. Understandably, based on the arrangement of the disconnecting slots 20, it is easier to quickly break the disconnecting slots 20 when the ignition device 3 explodes, thereby further improving the response timeliness of the circuit breaker.

[0045] Furthermore, considering factors such as the connectivity of the conductive bridge 2 during normal operation, its fragility upon breakage, and ease of production and processing, this embodiment further optimizes the structure / shape of the disconnecting groove 20 as follows: Please refer to the appendix. Figure 6 As shown, the disconnecting groove 20 extends along the width direction of the conductive bridge 2 and passes through both sides of the conductive bridge 2 in the width direction. The disconnecting groove 20 is divided into a first part 201 (including the groove opening) and a second part 202 (including the groove bottom) along its groove depth direction. The cross-section of the first part 201 in the groove depth direction of the disconnecting groove 20 is rectangular, and the cross-section of the second part 202 in the groove depth direction of the disconnecting groove 20 is a right trapezoid. Of course, according to design requirements, the cross-section of the second part 202 in the groove depth direction of the disconnecting groove 20 can also be designed as rectangular.

[0046] For further details, please refer to the appendix. Figure 5 As shown, this embodiment also provides two deflection slots 21 and two auxiliary slots 22 on the conductive bridge 2. The two deflection slots 21 are arranged side by side along the length direction of the conductive bridge 2, and the openings of the two deflection slots 21 open on the same surface of the conductive bridge 2 (specifically, the openings of the two deflection slots 21 are both open on the surface of the conductive bridge 2 facing the first outer casing 11). At least two disconnection slots 20 are distributed between the two deflection slots 21. The two auxiliary slots 22 are arranged back to back with the two deflection slots 21.

[0047] Regarding the functions of the deflection slot 21 and the auxiliary slot 22, the explanation is as follows: ① If the portion between each deflection slot 21 and its adjacent disconnection slot 20 is referred to as the deflection segment 24 (see Appendix) Figure 5 As shown), when the ignition device 3 explodes and breaks the disconnect groove 20, the two deflection segments 24 will deflect towards the inner cavity of the second outer shell 12, with the two deflection grooves 21 as rotating parts (which can be understood as rotation fulcrums). That is, the two opposite ends of the two deflection segments 24 will deflect under the action of the shock wave, enter the inner cavity of the second outer shell 12, and continue to rotate in a direction away from each other. At that time, the electric arc generated between the opposite ends of the two deflection segments 24 will be stretched and blown into an arc shape under the action of the shock wave, and blown to the arc extinguishing structure. The arc extinguishing structure will cut the electric arc to achieve the purpose of extinguishing the arc. ② By configuring the auxiliary groove 22, the two deflection segments 24 can more easily deflect around the deflection groove 21.

[0048] Next, regarding the ignition device 3 and the intelligent sensing control module 4.

[0049] In this embodiment, according to product design requirements, the ignition device 3 is preferably a gunpowder cup type ignition device, that is, the ignition device 3 contains gunpowder (explosive). As for the specific implementation structure of the gunpowder cup type ignition device, the gunpowder cup type ignition device structure provided in Chinese Patent ZL202320960565.9 is preferred. Of course, other preferred implementation structures can also be used, and this embodiment does not impose too many restrictions here.

[0050] In this embodiment, the preferred implementation structure of the intelligent sensing control module 4 is as follows: Please refer to the appendix. Figure 4 and attached Figure 8 As shown, the intelligent sensing control module 4 includes a control chip 40, a sensor assembly 41 for sensing the operating parameters of the conductive bridge 2 and electrically connected to the control chip 40, and a power input interface 42 for connecting to an external power supply 70. The power input interface 42 is electrically connected to the control chip 40 and the sensor assembly 41 respectively to provide power to the control chip 40 and the sensor assembly 41. The power input interface 42 is also electrically connected to the ignition device 3 through a first switch branch. The control chip 40 can control the on / off state of the first switch branch. Understandably, in the intelligent sensing control module 4, the power input interface 42 is used to connect to an external power supply 70, the sensor component 41 is used to sense the operating parameters of the conductive bridge 2 and transmit them to the control chip 40. After the control chip 40 analyzes and determines the operating parameters of the conductive bridge 2 (the specific analysis and determination method is described above), it controls the opening and closing of the first switch branch accordingly, thereby realizing the corresponding control of the ignition device 3 to disconnect or connect to the power input interface 42 / external power supply 70.

[0051] Furthermore, the sensor assembly 41 includes a temperature sensor 410 for sensing the temperature of the conductive bridge 2, a current sensor 411 for sensing the current flowing through the conductive bridge 2, and a pressure sensor (not shown) for sensing the air pressure in the first housing 11. The first switch branch includes a miniature relay 46; of course, in addition to relays, other types of electronic switches may also be used in the first switch branch.

[0052] Furthermore, in this embodiment, the intelligent sensing control module 4 is also provided with a signal input interface 43, a signal output interface 44, an energy storage device 49, and a PCB substrate 45. The signal input interface 43 and the signal output interface 44 are respectively used to electrically connect the control chip 40 to the external control system 71. The energy storage device 49 is electrically connected to the power input interface 42 and is also electrically connected to the ignition device 3 through a second switch branch. The control chip 40 can also control the on / off state of the second switch branch. The PCB substrate 45 is used to support the control chip 40, the sensor assembly 41, the power input interface 42, the signal input interface 43, the signal output interface 44, and the energy storage device 49. That is, the PCB substrate 45 is used as the mounting substrate of the intelligent sensing control module 4. Understandably, during the application of the circuit breaker, ① the external control system 71 generates various instructions (such as emergency instructions) for the operation of the ignition device 3 according to the actual working conditions, and the generated instructions are transmitted to the control chip 40 through the signal input interface 43. The control chip 40 controls the operation of the ignition device 3 accordingly according to the instructions. At the same time, the control chip 40 also generates a feedback signal and transmits it to the external control system 71 through the signal output interface 44. The external control system 71 controls the operation of other circuit breakers and equipment in the circuit system accordingly based on the feedback signal. ② When an unexpected power outage occurs, that is, when the power input interface 42 is disconnected from the external power supply 70, the control chip 40 can control the energy storage device 49 to supply power to the ignition device 3, thus further improving the safety and reliability of the circuit breaker during operation. Note: When the power input interface 42 is connected to the external power supply 70, the control chip 40 prioritizes supplying power to the ignition device 3 from the external power supply 70 over supplying power to the ignition device 3 from the energy storage device 49. That is, the energy storage device 49 is primarily used for handling emergency situations. Furthermore, the intelligent sensing control module 4 and the conductive bridge 2 are powered by two different power sources. This means that even if the power input interface 42 is unexpectedly disconnected from the external power supply 70, the conductive bridge 2 may still remain energized.

[0053] Furthermore, the second switch branch also includes a miniature relay 46. The energy storage device 49 includes an energy storage battery 47 and an energy storage capacitor 48 connected in series and parallel according to design requirements. Generally, the energy storage battery 47 and the energy storage capacitor 48 are designed to be connected in parallel, which allows the overall energy storage capacity of the energy storage device 49 to be large.

[0054] The PCB substrate 45 is shaped to match the second receiving cavity 112, and the periphery of the PCB substrate 45 is recessed with a pit 450 (see attached drawing). Figure 4As shown, the recess 450 can be slidably connected to the rib 1120 on the inner wall of the second receiving cavity 112.

[0055] Finally, the prefixes "first," "second," etc., in the component names in this patent specification (such as first housing, second housing, etc.) are only for clarity of description and are not intended to limit the scope of implementation of this patent.

[0056] In summary, the multi-channel intelligent circuit breaker of this invention has a simple and reasonable structure. It not only responds promptly but also intelligently, sensitively, and comprehensively senses its own electrical performance and operating parameters, greatly improving the safety and reliability of the circuit breaker and even the entire circuit system. Furthermore, in practical applications, the multi-channel intelligent circuit breaker of this invention can be composed of three sets of circuit breakers to form a three-phase circuit breaker group. This three-phase circuit breaker group can be a separate unit or an integrated unit, depending on the specific application.

[0057] Many specific details have been set forth in the foregoing description to provide a thorough understanding of the present invention. However, the above description is merely a preferred embodiment of the present invention, and the present invention can be implemented in many other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed above. Furthermore, any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, using the methods and techniques disclosed above, without departing from the scope of the present invention.
