Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to a current detection communication structure and an intelligent circuit breaker with a communication structure. Background Technology

[0002] In the field of circuit breaker technology, how to solve the problem of remote signal transmission and how to prevent accidental closing after a short circuit are major problems that existing intelligent circuit breakers need to solve.

[0003] For existing circuit breakers, the voltage flowing through them is typically 220V alternating voltage, resulting in a large current. Current circuit breakers use a circuit board to connect the communication structure to the circuitry. The communication structure operates with a relatively small current, and the circuit board converts this large current into a smaller one to provide signal collection and feedback to the communication structure. However, when a short circuit occurs, the instantaneous current becomes very large. Excessive current can easily burn out the circuit board, which may then become a conductor. If the circuit board cannot reduce the current, it can easily burn out the communication structure as well. Even if it doesn't burn out, the large current to small current conversion... It's also a proportional conversion. If the current flowing through the circuit board is too large, the conversion current will also increase, which can easily burn out the communication structure. This will prevent timely signal feedback and increase replacement costs. Moreover, the existing circuit breaker's control button uses springs and electromagnets for control. First, the spring, as an active component, does not have a limit function. The control button generally controls the lever. In this case, after the circuit breaker is short-circuited, it is easy to cancel the limit on the lever by pressing the button and continue to complete the closing operation. However, the circuit will definitely trip after a fault occurs. Closing the circuit under such circumstances can easily lead to electric shock or even fire risks.

[0004] Therefore, how to provide a current detection communication structure and an intelligent circuit breaker with a communication structure to solve the defects in the existing circuit breaker structure is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address this issue, the present invention provides a current detection communication structure and an intelligent circuit breaker with a communication structure, thereby solving the problems in the prior art where incomplete detection data and electric shock risks arise due to the communication structure being prone to burnout and the anti-closing structure having poor limiting effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0027] An arc-extinguishing chamber is installed in the mounting housing, which also houses an electromagnetic circuit breaker assembly. The arc-extinguishing chamber and the electromagnetic circuit breaker assembly are disposed between the bimetallic component and the drive assembly and are electrically connected through the overcurrent plate.

[0028] The gear set is installed in the mounting housing;

[0029] A gate opening and closing mechanism is installed in the mounting housing, and the gear set is meshed with one end of the gate opening and closing mechanism;

[0030] The jump-lock mechanism is installed in the mounting housing;

[0031] A pressure plate is installed above the arc-extinguishing chamber, gear set, drive assembly and electromagnetic circuit breaker assembly.

[0067] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0068] Please refer to Figures 1-5 The present invention will now describe a current detection communication structure, as follows: Figures 1-3 The device includes a driving component 1, a connecting frame 2, a connector 3, and a moving component 4. The connector 3 is installed inside the connecting frame 2. The moving component 4 is installed in the connecting frame 2 and is located to the left of the connector 3. One end of the moving component 4 is connected to the connector 3, and the other end of the moving component 4 extends out of the connecting frame 2. The driving component 1 is located outside the connecting frame 2. The connector 3 acts as a wire, used to electrically connect the moving component 4 to the communication device.

[0069] Based on the previous embodiment, such as Figure 2The driving component 1 includes a connecting post 11, a first electromagnet 12, and a wire 13. The first electromagnet 12 is mounted on the top side of the connecting post 11. The two ends of the wire 13 are connected to the pass-through plate, and the wire 13 is wound around the outside of the first electromagnet 12. The connecting post 11 is used to mount the first electromagnet 12. The middle section of the wire 13 is wound around the first electromagnet 12, and the two ends are connected to the pass-through plate, so that the first electromagnet 12 generates magnetism.

[0070] Based on the previous embodiment, such as Figures 4-5 The connector 3 includes a plug 31 and a first circuit board 32. The first circuit board 32 is installed inside the connector frame 2. One end of the first circuit board 32 is connected to several plugs 31, and the other end of the first circuit board 32 is connected to one end of the movable component 4. The plugs 31 are used to electrically connect the movable component 4 to the communication device, and the first circuit board 32 separates the inflow current from the outflow current.

[0071] Based on the previous embodiment, such as Figures 4-5 The movable component 4 includes a spring 41, a first magnet 42, a cable 43, a conductor 44, a displacement plate 45, and a sliding rod 46. The sliding rod 46 is disposed in the connecting frame 2 and between the first circuit board 32 and the side plate of the connecting frame 2. One end of the conductor 44 is sleeved on the outside of the sliding rod 46. The displacement plate 45 is connected to the connecting frame 2 and the conductor 44 is installed in the displacement plate 45. The other end of the conductor 44 is flush with the top wall of the displacement plate 45. The other end of the conductor 44 is connected to the cable 43, and the other end of the cable 43 is connected to the first circuit board 32. The first magnet 42 is installed on the displacement plate 45 and one end of the first magnet 42 extends out of the connecting frame 2. The springs 41 are arranged in pairs and installed between the displacement plate 45 and the first circuit board 32. Both the conductor 44 and the sliding rod 46 are made of metal. Current flows into the conductor 44 through the cable 43, passes through the sliding rod 46, and finally enters the first circuit board 32. Both the conductor 44 and the sliding rod 46 are made of conductive metal and have a certain resistance. Depending on the distance the current flows, the resistance is different, and the final current flowing out is also different. The spring 41 is set not only to reset the displacement plate 45 for the next detection, but also to keep the displacement plate 45 in a fixed position. In this way, the current flowing through it for a long time is the same, so it can be determined that the circuit is in an open circuit state. The way to keep the position unchanged is to keep the spring 41 in a compressed state, so that the displacement plate 45 is always pressed against the inner wall of the connecting frame 2.

[0072] In use, the communication device socket is connected to the connection frame 2, and the plug 31 connects to the conductor in the communication device. When current flows through the circuit breaker, the current flows through the overcurrent plate, and the wire 13 is connected in parallel to the overcurrent plate. No electrical appliance is installed on the wire 13, and its resistance is basically the same as the resistance of the current flowing through the overcurrent plate, so there will be no short circuit problem. The current flowing through the wire 13 will generate a magnetic field, which will activate the first electromagnet 12 to generate a magnetic force. The magnitude of the magnetic force depends on the magnitude of the current flowing through the wire 13. The magnetic force of the first electromagnet 12 will attract or repel the first magnet 42 to move. The movement of the first magnet 42 will cause the displacement plate 45 to move against the elastic force of the spring 41. The displacement plate 45 will simultaneously carry the conductor 44 to move. The movement of the conductor 44 along the sliding rod 46 is equivalent to the sliding rheostat changing its resistance. Through the change of resistance, the magnitude of the current flowing through the moving component 4 of the communication device is adjusted. The current will change, and the current signal in the circuit breaker will be fed back in real time through current fluctuations. The circuit breaker carries alternating current, and the direction of the current through conductor 13 will change. This will cause the magnetic direction generated by the first electromagnet 12 to also change, generating attraction and repulsion on the first magnet 42. The direction of the magnetic force will slowly decrease and increase during the change process, so the displacement plate 45 will move back and forth along the sliding rod 46. In this way, the current signal detected by the communication device changes in real time, and the detected signal is a sine wave signal. Compared with the communication device connected to the circuit board, this detection method can more clearly detect whether there is a voltage fluctuation problem. Compared with the existing electromagnetic feedback signal, it is less prone to electromagnetic interference problems, significantly improving detection accuracy. In case of short circuit or large current flow, the communication module is not directly connected to the circuit breaker, so there is no risk of damage.

[0073] Based on the same inventive concept, this invention also discloses an intelligent circuit breaker with a communication structure, such as... Figures 6-8The system includes a mounting housing 5, terminals 6, a limit assembly 7, a switching mechanism 8, a second circuit board 9, a pressure plate 10, a trip mechanism 20, an electromagnetic circuit breaker assembly 30, a gear set 40, a drive assembly 50, an arc-extinguishing chamber 60, and a bimetallic strip 70. A pair of terminals 6 are installed inside the mounting housing 5. The drive assembly 50 is installed inside the mounting housing 5, with the drive assembly 50 located inside one of the terminals 6. The bimetallic strip 70 is located inside the other terminal 6. The drive assembly 50 and the bimetallic strip 70 are connected to the terminals 6 via an overcurrent circuit board. The arc-extinguishing chamber 60 is installed inside the mounting housing 5. The mounting housing 5 also houses the electromagnetic circuit breaker assembly 30 and the arc-extinguishing chamber 60. The electromagnetic circuit breaker assembly 30 is disposed between the bimetallic component 70 and the drive assembly 50 and is electrically connected through the overcurrent plate. The gear set 40 is installed in the mounting housing 5. The opening and closing mechanism 8 is installed in the mounting housing 5. The gear set 40 is meshed with one end of the opening and closing mechanism 8. The tripping mechanism 20 is installed in the mounting housing 5. The pressure plate 10 is installed above the arc extinguishing chamber 60, the gear set 40, the drive assembly 50 and the electromagnetic circuit breaker assembly 30. A second circuit board 9 is installed above the pressure plate 10. The second circuit board 9 and the pressure plate 10 are both disposed inside the mounting housing 5. The limit assembly 7 is installed in the mounting housing 5. The limit assembly 7 and the tripping mechanism 20 are disposed on both sides of the opening and closing mechanism 8.

[0074] In this embodiment, the mounting housing 5, terminal block 6, opening and closing mechanism 8, second circuit board 9, pressure plate 10, trip mechanism 20, electromagnetic circuit breaker assembly 30, gear set 40, drive assembly 50, arc extinguishing chamber 60, and bimetallic component 70 are all common structures in circuit breakers. The limit assembly 7 solves the problem of accidental closing.

[0075] Based on the previous embodiment, such as Figures 9-10 A set of capacitor plates 91 are connected to the second circuit board 9. One end of a wire 92 is connected to each of the two capacitor plates 91. The middle section of the wire 92 is wound around the limiting component 7. The capacitor plates 91 serve as the energy source to drive the movement of the limiting component 7, and the wires 92 are used to generate magnetic force for the second electromagnet 78.

[0076] Based on the previous embodiment, such as Figure 11The opening and closing mechanism 8 includes a semi-circular insertion hole 81, a toggle block 82, a semi-circular block 83, an extension block 84, and a rotating rod 85. The rotating rod 85 is rotatably connected in the mounting housing 5. A semi-circular block 83 covers a part of the outer wall of the rotating rod 85, and an extension block 84 is installed on the other part of the outer wall of the rotating rod 85. A semi-circular insertion hole 81 is opened on the outer wall of the semi-circular block 83, and a number of gear teeth and grooves are provided at the other end of the extension block 84. The toggle block 82 is installed on the outside of the semi-circular block 83. The entire opening and closing mechanism 8 is rotated by the rotating rod 85. The semi-circular socket 81 is used to limit the opening and closing mechanism 8. The capacitor board 91 can only be used as a power source after the circuit is completely disconnected. During the circuit breaking process, a portion of the current actually flows through the second circuit board 9. Therefore, the limit component 7 can only lock the opening and closing mechanism 8 after the circuit breaking is completed. However, the circuit breaking is a very fast process, which will be completed in about 1-2 seconds. Therefore, the locking after the short circuit can also be completed quickly, which can effectively prevent the problem of accidental closing.

[0077] Based on the previous embodiment, such as Figures 12-13The limiting assembly 7 includes an electronic control button 71, a drive magnet 72, a drive plate 73, an arc-shaped block 74, a drive rack 75, an extension plate 76, a mounting plate 77, a second electromagnet 78, a limiting magnet 79, a second magnet 710, a first magnet 711, an extension block 712, a moving plate 713, and a drive gear 714. The electronic control button 71 is driven and connected to the mounting housing 5. Several drive magnets 72 are installed inside the electronic control button 71. The mounting plate 77 is installed in the mounting housing 5. A pair of second electromagnets 78 are installed on the side wall of the mounting plate 77. Wires 92 are wound around the two second electromagnets 78. The drive plate 73 is driven and connected to the mounting housing 5. One end of the drive plate 73 is connected to the arc-shaped block 74. The moving plate 713... The transmission connection is on the side wall of the mounting housing 5. Several first magnets 711 and second magnets 710 are installed in the movable plate 713. The first magnets 711 and second magnets 710 are arranged side by side. The first magnet 711 or the second magnet 710 is directly opposite the driving magnet 72. A rectangular hole is opened on the movable plate 713. An extension block 712 is installed in the rectangular hole. An extension plate 76 is installed at one end of the movable plate 713. A pair of limiting magnets 79 are installed on the extension plate 76. The limiting magnets 79 are directly opposite the second electromagnet 78. A round rod is installed on the inner side of the mounting plate 77. A driving gear 714 is installed on the round rod. A driving rack 75 is installed on the surfaces of the movable plate 713 and the driving plate 73 respectively. The driving rack 75 is meshed with the driving gear 714.For the movement of the limiting component 7, the unidirectional current generated by the capacitor plate 91 is typically supplied to the wire 92. The wire 92 generates a magnetic force on the second electromagnet 78. The second electromagnet 78 and the limiting magnet 79 are mutually repulsive magnets. When the second electromagnet 78 generates an electromagnetic force, it drives the limiting magnet 79 away, thereby driving the moving plate 713 to move outward. The first magnet 711 and the driving magnet 72 are opposite magnets, while the second magnet 710 and the driving magnet 72 are like magnets. Therefore, when the moving plate 713 moves outward, the second magnet 711... When the second magnet 710 is directly opposite the driving magnet 72, the like magnets repel each other, causing the electronic control button 71 to move outward. Simultaneously, the magnetic force of the driving magnet 72 is applied in the opposite direction to the second magnet 710, causing a slight offset of the moving plate 713, thus limiting its movement. At the same time, the movement of the moving plate 713 drives the driving gear 714 to rotate via the driving rack 75. The rotation of the driving gear 714 then drives the driving plate 73 to move, pressing the arc-shaped block 74 against the semi-arc-shaped socket 81, thus limiting the opening and closing mechanism 8. The driving force of an electromagnet is generally greater than the magnetic force of a permanent magnet. This lateral thrust will also drive the two permanent magnets to separate. Furthermore, before the capacitor plate 91 is completely depleted, it cannot drive the moving plate 713 to move, and therefore cannot drive the electronic control button 71 to move. Consequently, the restriction of the arc block 74 on the opening and closing mechanism 8 will not be lifted, effectively preventing accidental closing. Only after the electromagnetic force of the second electromagnet 78 disappears can the electronic control button 71 be pushed inward. However, due to the magnetic force of the permanent magnet, it is still difficult to reset. At this point, the main... The drive plate 73 moves inward with the same driving force as the electromagnet, which allows the two permanent magnets to be separated. After the drive plate 73 moves, the arc block 74 is released from its limiting position. At the same time, the first magnet 711 attracts the drive magnet 72, and the irregular magnets attract each other. In this case, the two magnets attract each other and can limit the drive plate 73 to a certain extent, so as to facilitate the next circuit breaker accidental closing operation. Using this magnet method, firstly, it has a certain limiting ability and is more durable than a spring, which can better prevent the accidental closing problem.

[0078] Based on the previous embodiment, such as Figures 14-15 Inside the mounting housing 5, there is a pair of clamping blocks 52. One end of the drive plate 73 is positioned between the two clamping blocks 52. Inside the mounting housing 5, there is a pair of U-shaped plates 51. The two ends of the movable plate 713 are locked in the U-shaped plates 51. The clamping blocks 52 prevent the drive plate 73 from moving out of position, while the U-shaped plates 51 ensure the smooth movement of the movable plate 713. To prevent the movable plate 713 from moving excessively, a groove can be made on the side wall of the mounting housing 5, and a rectangular block can be installed on the movable plate 713, allowing the rectangular block to move within the groove and limiting the amount of movement of the movable plate 713.

[0079] Based on the previous embodiment, such as Figure 16The trip mechanism 20 has a display panel 201 installed on its outer end, and a linkage rod 202 inserted into its top. The linkage rod 202 is inserted into the opening and closing mechanism 8. The dual-color display panel 201 indicates whether the circuit breaker is in a closed or open state, while the linkage rod 202 is a standard feature of the circuit breaker and is used to assist in opening and closing the circuit.

[0080] When in use, this invention has the same effect as a conventional circuit breaker when energized. When the opening and closing mechanism 8 rotates and is in the closed state, one end of the trip mechanism 20 is connected to the overcurrent plate on the side of the arc-extinguishing chamber 60. At this time, the current flows from one of the terminals 6, through the overcurrent plate in the circuit breaker, through the trip mechanism 20 and the bimetallic piece 70, and finally out through the other terminal 6, completing the circuit flow. Before the circuit is connected, the drive assembly 50 is energized. The drive assembly 50 and the gear set 40 use a worm gear engagement, so only by energizing the drive assembly 50 can the gear set 40 be triggered to rotate. This structure is designed for remote reset.

[0081] During the circuit breaking process, whether it's active or passive, the drive assembly 50 drives the gear set 40 to rotate. The gear set 40 then drives the opening and closing mechanism 8 to rotate, which in turn drives the tripping mechanism 20 to rotate. This causes one end of the tripping mechanism 20 to move away from the overcurrent plate on the side of the arc-extinguishing chamber 60, completing the circuit breaking operation. In the passive circuit breaking process, due to the short circuit, a large current will occur. This current will drive the drive rod in the electromagnetic circuit breaking assembly 30 to extend. The extended drive rod will push the tripping mechanism 20 to rotate, completing the circuit breaking. Furthermore, the bimetallic component 70 will also bend due to the high temperature caused by the large current, thus disconnecting the circuit. When the circuit is open, the alternating current supplies power to the second circuit board 9, which converts the current into direct current. The direct current charges the capacitor board 91. When a short circuit occurs, the electrical energy in the second circuit board 9 disappears, and the capacitor plate 91 begins to discharge, turning into a battery. The current generated by the capacitor plate 91 flows through the wire 92, causing the second electromagnet 78 to become magnetic. The magnetic force of the second electromagnet 78 drives the moving plate 713 to move outward. After moving, the second magnet 710 faces the driving magnet 72. The driving magnet 72 and the second magnet 710 have opposite magnetic properties, and the repulsive force drives the electronic control button 71 to move outward. Meanwhile, the driving magnet 72 applies a reverse magnetic force to the moving plate 713, causing the moving plate 713 to deflect invisibly. At this time, a certain limit is applied to the moving plate 713 to prevent it from slipping. Before the charge in the capacitor plate 91 is completely discharged, the limit component 7 still limits the opening and closing mechanism 8 to prevent accidental closing and electric shock risk for a period of time.

Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
