DETAILED DESCRIPTION

As known from the above, when the circuit breaker is applied to a circuit system, the working principle of the circuit breaker is that the intelligent sensing control module 4 real-time senses the working parameters (such as the working current, the ambient temperature and the ambient air pressure, etc.) of the conductive bridge 2, and analyzes and judges the sensed working parameters: if all the working parameters are within the preset threshold range, it is judged that the working state of the conductive bridge 2 is normal; and if one or more of the working parameters is not within the preset threshold range, it is judged that the working state of the conductive bridge 2 is abnormal. At the same time, the intelligent sensing control module 4 also controls the igniter 3 to work according to the judgment result, specifically as follows: ① when the intelligent sensing control module 4 judges that the working state of the conductive bridge 2 is normal, the intelligent sensing control module 4 controls the igniter 3 to keep disconnected with the power supply part; ② when the intelligent sensing control module 4 judges that the working state of the conductive bridge 2 is abnormal, the intelligent sensing control module 4 controls the igniter 3 to be connected to the power supply part. The igniter 3 explodes after being powered on, which realizes the breaking groove 20 to be broken (i.e. the conductive bridge 2 is cut off) within 2ms, so as to cut off the current and protect the circuit system. It can be understood that the circuit breaker provided by the embodiment not only responds timely, but also intelligently, sensitively and comprehensively senses the electrical performance / working parameters of itself, so as to greatly improve the safety and reliability of the circuit breaker and even the whole circuit system during working.

[0034] The specific structure of the multi-channel intelligent circuit breaker of the embodiment is described in detail below.

[0035] Firstly, the shell 1 and its contents.

[0037] Further, based on the connection mode between the first shell body 11 and the second shell body 12 and the structure of the conductive bridge 2 (generally, the conductive bridge 2 is a long strip plate), the conductive bridge 2 is clamped between the first shell body 11 and the second shell body 12, and the specific clamping mode is: please continue to refer to the accompanying Figure 2 As shown, if the first shell body 11 is defined as being above the second shell body 12, the first shell body 11 is concave upward on the opposite sides of the lower side of the first shell body 11, and the second shell body 12 is concave downward on the opposite sides of the upper side of the second shell body 12, and the clamping grooves 13 on the first shell body 11 and the second shell body 12 are oppositely arranged, that is, the clamping grooves 13 on the first shell body 11 and the second shell body 12 can be adjacently connected to realize the receiving and limiting of the conductive bridge 2. When assembling, the conductive bridge 2 can be placed in the clamping groove 13 on the second shell body 12, and then the first shell body 11 and the second shell body 12 are adjacently connected and fixed by screws, at which time the clamping grooves 13 on the first shell body 11 and the second shell body 12 are adjacently connected to receive and limit the conductive bridge 2.

[0038] Further, the embodiment also provides positioning structures between the conductive bridge 2 and the second shell body 12 for positioning connection and cooperation to further improve the stability of the conductive bridge 2.

[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 breaking groove 20 extends along the width direction of the conductive bridge 2 and penetrates both sides of the conductive bridge 2 width direction respectively, the breaking groove 20 is divided into a first part 201 (containing a notch) and a second part 202 (containing a groove bottom) along the groove depth direction thereof, and the cross section of the first part 201 in the groove depth direction of the breaking groove 20 is rectangular, and the cross section of the second part 202 in the groove depth direction of the breaking 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 breaking groove 20 can also be designed as a rectangle.

[0046] Further, please continue to refer to the accompanying Figure 5 As shown, the embodiment also has two deflection grooves 21 and two auxiliary grooves 22 on the conductive bridge 2, wherein two deflection grooves 21 are arranged side by side along the length direction of the conductive bridge 2, and the notches of the two deflection grooves 21 are opened on the same surface of the conductive bridge 2 (specifically, the notches of the two deflection grooves 21 are opened on the surface of the conductive bridge 2 facing the first outer shell 11), and at least two breaking grooves 20 are distributed between the two deflection grooves 21; two auxiliary grooves 22 are arranged opposite to two deflection grooves 21 one by one.

[0047] And regarding the functions of the deflection groove 21 and the auxiliary groove 22, the explanation is as follows: ①If the part between each deflection groove 21 and its adjacent breaking groove 20 is called a deflection segment 24 (see the accompanying Figure 5 As shown), after the igniter 3 explodes and breaks the breaking groove 20, the two deflection segments 24 will respectively take the two deflection grooves 21 as the rotation part (understandable as the rotation fulcrum) and deflect towards the inner cavity of the second outer shell 12, that is, the two opposite ends of the two deflection segments 24 will deflect under the action of the shock wave and enter the inner cavity of the second outer shell 12, and also continue to rotate in the direction away from each other; At that time, the electric arc generated between the two 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, which will cut the electric arc and achieve the purpose of arc extinguishing. ②By configuring the auxiliary groove 22, the two deflection segments 24 are more easily deflected around the deflection groove 21.

[0048] Next, regarding the igniter 3 and the intelligent induction control module 4.

[0049] In the present embodiment, according to the product design requirement, the igniter 3 preferably adopts a cartridge-type igniter, i.e., the igniter 3 is filled with gunpowder (explosive). As for the specific implementation structure of the cartridge-type igniter, the structure of the cartridge-type igniter provided in Chinese patent ZL202320960565.9 can be preferably adopted, of course, other preferred implementation structures can also be adopted, and the present embodiment does not make too many limitations here.

[0050] In the present embodiment, the implementation structure of the intelligent induction control module 4 is preferably as follows: please continue to refer to the attached Figure 4 and Figure 8 As shown in the drawings, the intelligent induction control module 4 is provided with a control chip 40, a sensor assembly 41 for sensing the working parameters of the conductive bridge 2 and at the same time electrically connected with the control chip 40, and a power input interface 42 for connecting with an external power supply 70, the power input interface 42 is respectively electrically connected with the control chip 40 and the sensor assembly 41 to provide electrical energy to the control chip 40 and the sensor assembly 41, and the power input interface 42 is also electrically connected with the igniter 3 through a first switch branch, and the control chip 40 can control the on-off of the first switch branch. It can be understood that in the intelligent induction control module 4, the power input interface 42 is used to access the external power supply 70, the sensor assembly 41 is used to sense the working parameters of the conductive bridge 2 and transmit them to the control chip 40, and the control chip 40 analyzes and judges the working parameters of the conductive bridge 2 (the specific analysis and judgment method is described above), and controls the on-off of the first switch branch accordingly, thereby realizing the corresponding control of the igniter 3 to be disconnected or connected to the power input interface 42 / external power supply 70.

It can be understood that, in the application process of the circuit breaker, ① the external control system 71 can generate various instructions (such as emergency instructions) for the operation of the igniter 3 according to the actual working condition, 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 igniter 3 according to the instructions, and 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, and the external control system 71 controls the operation of other circuit breakers, devices and the like in the circuit system according to the feedback signal. ② When an unexpected power failure occurs, that is, the power input interface 42 is disconnected from the external power source 70, the control chip 40 can control the power supply of the igniter 3 by the energy storage component 49, which further improves the safety and reliability of the operation of the circuit breaker. It is specified that when the power input interface 42 is connected with the external power source 70, the priority of the control chip 40 for controlling the power supply of the igniter 3 by the external power source 70 is higher than that by the energy storage component 49, that is, the energy storage component 49 is mainly used for handling emergency situations. In addition, the intelligent induction control module 4 and the conductive electric bridge 2 are powered by two different power sources, that is, when the unexpected situation of the power input interface 42 being disconnected from the external power source 70 occurs, the conductive electric bridge 2 can still remain in a powered state.

[0053] Further, the second switch branch also includes a micro relay 46.
