Description

Technical Field

[0001] This invention relates to the field of electrical safety protection technology, specifically to a circuit breaker with multi-node power outage protection function. Background Technology

[0002] Circuit breakers are crucial protective devices in power systems, used to quickly disconnect circuits when faults such as overload, short circuit, and leakage occur, ensuring the safety of electrical equipment and personnel. Traditional circuit breakers typically monitor and protect against faults at a single node or of a single type, such as only monitoring changes in the current of the main circuit to determine whether there is an overload or short circuit, making it difficult to cope with multi-node faults in complex circuit environments.

[0003] Existing circuit systems often contain multiple branch nodes and electrical equipment. Failure at any node can lead to safety hazards. Furthermore, there is a lack of effective split-type node connection structures. When switching circuit node connections is required, the wiring harness needs to be repeatedly disassembled and reassembled, which has limitations. When a leakage occurs at a branch node, traditional circuit breakers may not be able to detect and disconnect the branch in time, resulting in the leakage persisting. In addition, when both the main circuit and the branch circuit are overloaded at the same time, traditional circuit breakers may experience delays or malfunctions due to their simple protection logic. Moreover, the protection parameters of existing circuit breakers are usually fixed values, making it difficult to flexibly adjust them according to the electrical characteristics of different nodes, resulting in poor adaptability. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a circuit breaker with multi-node power failure protection. This effectively solves the problems of existing circuit systems, which often contain multiple branch nodes and electrical equipment. Failure at any node can lead to safety hazards, and the lack of an effective split-type node connection structure means that switching circuit node connections requires repeated disassembly and reassembly of the wiring harness, which is limiting. Furthermore, when a branch node experiences leakage, traditional circuit breakers may fail to detect and disconnect the branch in time, resulting in persistent leakage. Additionally, when both the main circuit and branch circuits experience overload simultaneously, traditional circuit breakers may experience delayed or erroneous operation due to their simple protection logic. Moreover, the protection parameters of existing circuit breakers are typically fixed values, making it difficult to flexibly adjust them according to the electrical characteristics of different nodes, resulting in poor adaptability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a circuit breaker with multi-node power failure protection function, including a housing mechanism, wherein a guide plate is fixedly connected to the outer side of the housing mechanism, wherein every two laterally adjacent guide plates form a group, and two groups of guide plates are fixedly connected to the left end face of the housing mechanism in a longitudinal array. The guide plate has a transverse groove inside, which is a guide groove. A limit hole is opened at the right end of the guide groove. A split mechanism is inserted into the inner side of the guide plate. An anti-slip protrusion is fixedly connected to the outer side of the split mechanism. A wire hole is opened at the left end of the split mechanism for passing through the wire harness. A screw hole is opened at the top end of the split mechanism. A fixing bolt is screwed into the screw hole to limit the wire harness. A spring limiting rod is inserted into the split mechanism. Two spring limiting rods matching the limit hole are installed on the front and rear sides of each split mechanism. A cylindrical top rod is fixedly connected to the right end face of the split mechanism. A metal plate for connecting the power supply is provided on the right end face of the top rod.

[0008] Furthermore, a guide slider is fixedly connected to the outer peripheral surface of the guide plate assembly. There are four guide sliders in total, and the four guide sliders are fixedly connected to the outer peripheral surface of the guide plate assembly in a circular array. The guide plate assembly is slidably connected to the inner side of the sleeve mechanism through the guide sliders. The left end face of the return spring A is fixedly connected to the right end face of the guide plate assembly. The right end face of the return spring A is fixedly connected to the inner left end face of the sleeve mechanism.

[0009] Furthermore, a contact component is fixedly connected to the center of the right end face of the guide plate assembly. The contact component passes through the sleeve mechanism to the right, and a groove is provided on the right side of the contact component. This groove is a contact slot, which is used to connect the power supply.

[0010] Furthermore, a contact mechanism is inserted inside the housing mechanism. The main body of the contact mechanism is a cylindrical structure, and there are three contact mechanisms in total. The three contact mechanisms are arranged in a longitudinal array and inserted into the right end face of the housing mechanism. The three contact mechanisms and the three sleeve mechanisms are arranged in parallel and opposite directions. A contact head is fixedly connected to the side of the contact mechanism closest to the sleeve mechanism.

[0011] Furthermore, the contact head matches the contact groove, and when the contact head is inserted into the contact groove, the circuit is in a connected state. A toothed assembly is fixedly connected to the rear side of the outer peripheral surface of the contact mechanism, and a baffle assembly is fixedly connected to the side of the contact mechanism away from the housing mechanism. A return spring B is fixedly connected to the left side of the baffle assembly, and the left side of the return spring B is fixedly connected to the right end face of the housing mechanism.

[0012] Furthermore, a connecting component is fixedly connected to the side of the baffle assembly away from the contact mechanism. The connecting component has a screw hole inside, and a positioning bolt is screwed into the screw hole. The connecting component and the positioning bolt together form a connection structure for the wire. A guide rod mechanism is inserted into the rear side of the housing mechanism.

[0013] Furthermore, the main body of the guide rod mechanism is a cylindrical structure, and there are three guide rod mechanisms in total. The three guide rod mechanisms are longitudinally arrayed and inserted into the inner side of the housing mechanism. Limiting baffles A and B are fixedly connected in a linear array on the outer circumferential surface of the guide rod mechanism. A reset spring C connected to the inner front face of the housing mechanism is fixedly connected to the rear end face of the limiting baffle A. The limiting baffle A is located inside the housing mechanism, and the limiting baffle B is located at the rear side of the housing mechanism.

[0014] Furthermore, a connecting frame is fixedly connected to the front end face of the guide rod mechanism, a servo motor is installed at the top of the connecting frame, and a drive gear is installed on the bottom output shaft of the servo motor. The drive gear meshes with the gear rack assembly for transmission. A limit support is fixedly connected to the rear end face of the housing mechanism. An electromagnet is fixedly connected inside the limit support, and a return spring D is fixedly connected to the same side of the limit support. A moving guide block and a slider assembly are fixedly connected to the side of the return spring D away from the limit support. A limit stop plate for limiting the limit baffle B is fixedly connected to the far end of the moving guide block. The electromagnet is in a state of instantaneous high current passing through it, and the electromagnet is in a state of generating magnetism when energized and attracting the moving guide block.

[0015] The technical solution provided by this invention has the following advantages compared with the prior art: This invention utilizes a plug-in connection structure between a split mechanism and a guide plate, employing the rapid engagement and disengagement of a spring-loaded limit rod and a limit socket to facilitate convenient switching of circuit node connections. This eliminates the need for repeated disassembly and assembly of the wiring harness, overcoming the limitations of cumbersome operation when switching nodes in existing circuit breakers. Simultaneously, the use of a fixing bolt to stably limit the wiring harness ensures the reliability of the node connection. Through three independent sleeve mechanisms, contact mechanisms, and corresponding temperature sensing components, a multi-node independent monitoring and protection unit is formed. When a branch node experiences abnormal temperature or other faults, the temperature sensing component triggers the protection mechanism. An electromagnet drives a moving guide block, which in turn releases the limit plate from the guide rod mechanism. The guide rod mechanism, via a servo motor... The meshing transmission of the drive gear and gear rack assembly pushes the contact mechanism and contact assembly to separate, realizing rapid power disconnection of a single fault node and preventing the fault from spreading to other nodes. This solves the problem that traditional circuit breakers can only protect a single node or a single type of fault. Moreover, the protection structure of each node operates independently, and with the elastic reset action of the reset springs A, B, C, and D, it can quickly respond to cut off the circuit during a fault and stably restore the connection after the fault is cleared. At the same time, the protection logic can be flexibly adjusted according to the power consumption characteristics of different nodes, overcoming the defects of fixed protection parameters and poor adaptability of traditional circuit breakers. It effectively copes with multi-node faults in complex circuit environments and improves the comprehensiveness and reliability of circuit protection. Attached Figure Description

[0024] A guide slider 4011 is fixedly connected to the outer peripheral surface of the guide plate assembly 401. There are four guide sliders 4011 in total. The four guide sliders 4011 are fixedly connected to the outer peripheral surface of the guide plate assembly 401 in a circular array.

The right end face of the return spring A4012 is fixedly connected to the inner left end face of the sleeve mechanism 4.

[0025] A contact component 4013 is fixedly connected to the center of the right end face of the guide plate assembly 401. The contact component 4013 passes through the sleeve mechanism 4 to the right, and a groove is provided on the right side of the contact component 4013. The groove is a contact groove 4014, which is used to connect the power supply. A controller 1012 is fixedly connected to the top surface inside the housing mechanism 1, and a door assembly 1013 is also hinged to the front opening of the housing mechanism 1.

[0026] The housing mechanism 1 is internally connected to a contact mechanism 5. The main body of the contact mechanism 5 is a cylindrical structure, and there are three contact mechanisms 5. The three contact mechanisms 5 are arranged in a longitudinal array and inserted into the right end face of the housing mechanism 1. The three contact mechanisms 5 and the three sleeve mechanisms 4 are arranged in parallel and opposite to each other. A contact head 501 is fixedly connected to the side of the contact mechanism 5 closest to the sleeve mechanism 4.

[0027] The contact head 501 is matched with the contact groove 4014. When the contact head 501 is inserted into the contact groove 4014, the circuit is connected. The toothed assembly 5011 is fixedly connected to the rear side of the outer peripheral surface of the contact mechanism 5. The baffle assembly 5012 is fixedly connected to the side of the contact mechanism 5 away from the housing mechanism 1. The return spring B5013 is fixedly connected to the left side of the baffle assembly 5012. The left side of the return spring B5013 is fixedly connected to the right end face of the housing mechanism 1.

[0028] A connecting component 5014 is fixedly connected to the side of the baffle assembly 5012 away from the contact mechanism 5. The connecting component 5014 has a screw hole inside, and a positioning bolt 5015 is screwed into the screw hole. The connecting component 5014 and the positioning bolt 5015 together form a connection structure for the wire. A guide rod mechanism 6 is inserted into the rear side of the housing mechanism 1.

[0029] The main body of the guide rod mechanism 6 is a cylindrical structure, and there are three guide rod mechanisms 6 in total. The three guide rod mechanisms 6 are longitudinally arrayed and inserted into the inner side of the housing mechanism 1. The outer circumferential surface of the guide rod mechanism 6 is fixedly connected to the limiting baffle A601 and the limiting baffle B6012 in a linear array. The rear end face of the limiting baffle A601 is fixedly connected to the return spring C6011, which is connected to the front end face of the inner side of the housing mechanism 1. The limiting baffle A601 is located inside the housing mechanism 1, and the limiting baffle B6012 is located at the rear side of the housing mechanism 1.

[0030] A connecting frame 6013 is fixedly connected to the front end face of the guide rod mechanism 6. A servo motor 6014 is installed at the top of the connecting frame 6013. A drive gear 6015 is installed on the bottom output shaft of the servo motor 6014. The drive gear 6015 meshes with the gear rack assembly 5011 for transmission. A limit support 7 is fixedly connected to the rear end face of the housing mechanism 1. An electromagnet 701 is fixedly connected inside the limit support 7. A return spring D7011 is also fixedly connected to the same side of the limit support 7. A moving guide block 7012 and a slider assembly 7013 are fixedly connected to the side of the return spring D7011 away from the limit support 7. A limit stop plate 7014 for limiting the limit stop plate B6012 is fixedly connected to the far end of the moving guide block 7012. When the electromagnet 701 is in a state of instantaneous high current passing through it, the electromagnet 701 is in a state of generating magnetism when energized and attracting the moving guide block 7012.

[0031] Working principle: First, the wire harness is passed through the wire hole 3011 of the split mechanism 3. Tightening the fixing bolt 3012 can squeeze and limit the wire harness to prevent it from loosening. The anti-slip protrusion 301 pushes the split mechanism 3 to be inserted into the guide groove 201 of the guide support plate 2. At this time, the spring limiting rods 3013 on the front and rear sides of the split mechanism 3 are squeezed and contracted by the inner wall of the guide groove 201. When the split mechanism 3 is fully inserted to the right end of the guide groove 201, the spring limiting rod 3013 aligns with the limiting insertion hole 2011 and pops out to engage, thus fixing the split mechanism 3 to the guide support plate 2. At the same time, the metal piece on the right end of the split mechanism 3 contacts the guide plate assembly 401, laying the foundation for circuit connection. The right end of the return spring A4012 is fixed to the left end face inside the sleeve mechanism 4, and the left end is connected to the guide plate assembly 401. Its elastic force keeps the guide plate assembly 401 in the initial left position inside the sleeve mechanism 4 via the guide slider 4011. At this time, the contact groove 4014 of the contact assembly 4013 is in the waiting-to-connect state. The left end of the return spring B5013 is fixed to the right end face of the housing mechanism 1, and the right end is connected to the baffle assembly 5012. Its elastic force pushes the contact mechanism 5 to the right to maintain the initial position, so that the contact head 501 and the contact... When the contact groove 4014 separates, the rear end of the return spring C6011 is fixed to the front end face inside the housing mechanism 1, and the front end is connected to the limiting baffle A601. Its elastic force pushes the guide rod mechanism 6 backward to maintain the initial position. At this time, the limiting baffle B6012 is blocked by the limiting stop plate 7014. One end of the return spring D7011 is fixed to the limiting support 7, and the other end is connected to the moving guide block 7012. Its elastic force pushes the moving guide block 7012 to drive the limiting stop plate 7014 to maintain the blocking state of the limiting baffle B6012. When it is necessary to connect a certain node circuit, the servo motor 6014 starts and drives the drive gear 6015 to rotate. The drive gear 6015 meshes with the gear assembly 5011 of the contact mechanism 5, pushing the contact mechanism 5 to move towards the sleeve mechanism 4 against the elastic force of the return spring B5013. The contact mechanism 5 drives the contact head 501 to move to the left and inserts the contact head 501 into the contact groove 4014 of the contact assembly 4013. At the same time, the contact assembly 4013 is pushed by the contact head 501, which drives the guide plate assembly 401 to slide to the right along the guide slider 4011 in the sleeve mechanism 4 against the elastic force of the return spring A4012. At this time, the circuit is connected. The connecting assembly 5014 fixes the external wires through the positioning bolt 5015 to form a complete circuit. The heat dissipation groove 101 at the bottom of the housing mechanism 1 dissipates internal heat through air circulation, preventing components from failing due to high temperature. The three temperature measuring components 1011 at the rear end of the housing mechanism 1 perform non-contact temperature monitoring on the corresponding node areas, capturing the temperature changes of each node in real time and providing trigger signals for fault protection. When the temperature measuring component 1011 of a certain node detects an abnormal temperature, the electromagnet 701 is instantly energized and generates magnetism, attracting the moving guide block 7012 to overcome the elastic force of the return spring D7011 and move towards the limit support 7, causing the limit plate 7014 to disengage from the limit baffle B6012. At this time, the return spring C6011 pushes the guide rod mechanism 6 to move backward, and the connecting frame 6013 drives the servo motor 6014 and the drive gear 6015 to move backward synchronously. The drive gear 6015 disengages from the gear assembly 5011. At this time, the contact mechanism 5 moves to the right under the pulling action of the return spring B5013, so that the contact component 4013 is completely separated from the contact head 501, and the circuit of the fault node is disconnected. After troubleshooting, electromagnet 701 is de-energized and loses its magnetism. Moving guide block 7012 is reset under the elastic force of reset spring D7011. At this time, the limit stop plate 7014 needs to be manually pulled beforehand, and the guide rod mechanism 6 is pushed forward to reset, so that the limit stop plate 7014 blocks the limit baffle B6012 again, and the drive gear 6015 re-engages with the gear assembly 5011. At this time, the servo motor 6014 rotates in the forward direction, and the drive gear 6015 pushes the contact mechanism 5 to overcome the elastic force of reset spring B5013 and move towards the sleeve mechanism 4 through meshing transmission. The contact head 501 is reinserted into the contact groove 4014, and the circuit is restored.
