Description
A cellular intelligent phase-switching power distribution system Technical Field
[0001] This application relates to the field of electrical equipment technology, and in particular to a cellular smart phase-switching power distribution system. Background Technology
[0002] In the field of electrical equipment technology, the development of power distribution systems is of paramount importance. With the continuous growth of electricity demand and the increasing diversification of electrical equipment, higher requirements are being placed on the stability, reliability, and safety of power distribution systems. Efficient and stable power distribution systems ensure the rational allocation and transmission of electricity, providing reliable power support for various electrical devices. They are widely used in numerous fields such as industrial production, commercial operations, and residential life, exerting a profound impact on socio-economic development and people's daily lives.
[0003] In related technologies, various methods are typically employed to achieve functions such as circuit connection control, overload protection, anti-pumping interlocking, and low-voltage detection. For circuit connection control, traditional electromagnetic relays are commonly used to control the circuit's on / off state. Electromagnetic force causes contacts to close or open, thus connecting or disconnecting the circuit. For overload protection, thermal relays are generally used. When the current in the circuit exceeds the rated value, the heating element of the thermal relay generates heat, deforming the bimetallic strip and actuating the contacts to cut off the circuit, providing protection. To prevent malfunctions or tripping, mechanical locking devices are often used to lock the switch's state, ensuring the circuit remains stable after closing or opening. For low-voltage detection, simple voltage sensors are often used. When the detected voltage is lower than a set value, an alarm signal is issued, but this often cannot directly disconnect the circuit.
[0004] Electromagnetic relays are prone to contact wear and adhesion during frequent operation, leading to reduced circuit control reliability. Thermal relays have a relatively slow response speed and may fail to react promptly to rapidly changing overload conditions, thus failing to effectively protect the circuit. Mechanical locking devices have a complex structure, are difficult to install and maintain, and are prone to loosening and malfunction during long-term use, failing to ensure correct closing or opening of the circuit breaker assembly. Simple voltage sensors can only issue alarm signals and cannot automatically disconnect the circuit; therefore, they cannot guarantee circuit safety when the closing / opening assembly malfunctions.

[0021] By adopting the above technical solution, the closing and opening switch rod has a snap-fit hole and a first pressure sensor. When the closing and opening switch rod slides to the target position, the locking block triggers the first pressure sensor, which in turn causes the drive motor to drive the drive gear to rotate and push the locking block into the snap-fit hole, effectively preventing the closing and opening switch rod from tripping during use.
[0022] Preferably, the mounting box contains a fixed box, the fixed frame is slidably mounted inside the fixed box, and a second pressure sensor is provided on the side wall of the fixed box. The second pressure sensor is electrically connected to an indicator light. When the locking block is fully engaged, the fixed frame displaces and contacts the second pressure sensor, triggering the indicator light.
[0023] By adopting the above technical solution, when the locking block is fully engaged, the fixed frame displaces and contacts the second pressure sensor, triggering the indicator light to indicate the opening and closing status, thus facilitating observation by staff.
[0024] Preferably, the drive motor is connected to the drive gear via a worm gear.

[0033] By adopting the above technical solution, the voltage comparator of the low-voltage detection component monitors the battery voltage in real time, and the trip controller forces the trip lever to trip when the voltage is lower than a predetermined threshold. During forced tripping, the rotary motor drives the rotating tube to rotate, which in turn drives the control board to slide away from the connecting rod.

This can effectively respond to the circuit control module to disconnect or connect the circuit, and solves the problems of easy wear and sticking of contacts and low reliability of traditional electromagnetic relays.
[0040] 2.

Furthermore, a flexible metal sheet 505 is fitted onto the connector 502.
[0060] Mounting box 3 is connected to fuse 506 by screws, and fuse 506 is located between two fixing posts. One fixing post is fixedly connected to a connecting copper plate 507 by screws, and one end of the connecting copper plate 507 is fixedly connected to an input head 508 by screws. The screw of the other fixing post extends towards the vacuum circuit breaker, and the extended end of the screw is connected to a flexible metal sheet 505.
[0061] Referring to Figures 4, 5, and 7, the anti-jump interlocking assembly 6 includes a bevel gear 601 sleeved around the closing / opening lever 409. A fixing box 31 is provided inside the mounting box 3. A drive gear 602 and a fixing frame 603 are slidably disposed within the fixing box 31, with a gap between the drive gear 602 and the bevel gear 601. A closing gear 604 and an opening gear 605 are rotatably connected to the fixing frame 603. The closing gear 604 and the opening gear 605 are located within the gap between the drive gear 602 and the bevel gear 601. The closing gear 604 meshes with the drive gear 602 and the bevel gear 601, and the opening gear 605 meshes with the drive gear 602 and the bevel gear 601. Both the closing gear 604 and the opening gear 605 are fixedly connected with locking blocks 606. At the same time, the closing and opening rod 409 is provided with a locking hole 32 that cooperates with the corresponding locking block 606. When closing, the closing and opening rod 409 slides down, and the locking block 606 on the closing gear 604 extends into the corresponding locking hole 32. When opening, the closing and opening rod 409 slides up, and the locking block 606 on the opening gear 605 extends into the corresponding locking hole 32.
[0062] A first pressure sensor 607 is fixedly connected to the closing / opening lever 409 at the locking hole 32. The first pressure sensor 607 is electrically connected to a drive motor 608, which is fixedly connected inside the mounting box 3. The drive motor 608 is connected to the drive gear 602 via a worm gear, thereby controlling and reducing the speed of the drive gear 602. When the closing / opening lever 409 slides to and abuts against the first pressure sensor 607, the drive motor 608 manipulates the drive gear 602 to rotate further in the closing or opening direction, causing the locking block 606 on the opening gear 605 or closing gear 604 to further insert into the locking hole 32 and engage with the locking hole 32, thereby effectively preventing the closing / opening lever 409 from tripping during use.
[0063] Referring to Figures 2, 4, and 7, second pressure sensors 610 are fixedly connected to the side walls of the fixed box 31 at the same height as the fixed frame 603. Both second pressure sensors 610 are electrically connected to the indicator light 13 and control panel 12, which are fixedly connected to the surface of the drawer panel 9. When the drive gear 602 rotates towards closing or opening, the fixed frame 603 slides along the fixed box 31. When the locking block 606 engages with the locking hole 32, the fixed frame 603 contacts the corresponding second pressure sensor 610, thereby triggering the second pressure sensor 610 and illuminating the indicator light 13 to indicate the closing or opening status. Simultaneously, the second pressure sensors 610 on different sides are triggered during closing and opening, and the pressure signals from the second pressure sensors 610 on different sides are transmitted to the control panel 12 and displayed. In addition, the control panel 12 is electrically connected to the drive motor 608. When switching the gate position, the control panel 12 controls the drive gear 602 to rotate, and causes the fixed frame 603 to separate from the triggered second pressure sensor 610. At this time, the pressure signal received by the control panel 12 returns to zero, thereby causing the locking block 606 to disengage from the closing / opening gate lever 409.
[0064] Referring to Figures 2 and 4, the low-voltage detection component 7 includes a voltage comparator 701 and a trip controller 702. The voltage comparator 701 is fixedly connected inside the mounting box 3 and is electrically connected to the battery 401 and the control panel 12 to monitor the voltage of the battery 401 in real time and transmit the detected data to the control panel 12 in real time for easy observation by the staff.

Furthermore, a mating groove 34 is provided on the bottom surface of the rotating tube 7022, and a second threaded groove 36 matching the first threaded groove 33 is provided on the inner wall of the mating groove 34.
[0066] Referring to Figures 2, 4, and 7, a rotary motor 704 electrically connected to a voltage comparator 701 is fixedly connected inside the mounting box 3, and the output shaft of the rotary motor 704 is connected to the surface of the rotating tube 7022 via a belt.
[0067] Referring to Figures 6, 7, and 8, the drive groove 26 has a second limiting groove 35, which is located below the first limiting groove 28. Meanwhile, the locking hole 32 near the closing gear 604 is open and faces upwards. When forced to open, the rotary motor 704 drives the rotating tube 7022 to rotate and drives the control plate 7023 to slide away from the connecting rod 415. The control plate 7023 pushes the drive rod 7021 into the mating groove 34 through preload, causing the first threaded groove 33 to mate with the second threaded groove 36. At this time, the drive rod 7021 drives the closing / opening rod 409 to slide downwards, causing the sliding protrusion 408 on the surface of the second permanent magnet 407 to deform and extend into the second limiting groove 35. Furthermore, the locking block 606 on the closing gear 604 disengages from the closing / opening rod 409 from the opening of the corresponding locking hole 32.
[0068] The implementation principle of this application embodiment is as follows: The cellular intelligent phase-commutation power distribution system of this application embodiment monitors the grid status (such as phase imbalance, load changes, etc.) in real time through the circuit control module 1, and intelligently generates phase-commutation commands according to a preset strategy. The cellular drive group responds to the commands, driving multiple drive modules 2 to work together to realize dynamic phase-commutation power distribution.
[0069] When the circuit control module 1 detects a need to switch the circuit connection mode (such as optimizing phase allocation), it sends a command to the target drive module 2. The closing / opening assembly 4 responds to the command: the auxiliary switch 402 closes, the battery 401 supplies power to the coil 404, enhancing the magnetic force of the first permanent magnet 406 (neodymium iron boron permanent magnet), attracting the second permanent magnet 407 to drive the closing / opening lever 409 to slide linearly (opening upwards or closing downwards), achieving rapid circuit disconnection or connection. The polyimide enameled copper wire coil 404 withstands high temperatures (>180℃), ensuring stability under frequent operation.
[0070] When the closing / opening lever 409 slides, the bevel gear 601 drives the closing gear 604 and the opening gear 605 to rotate, and the locking block 606 rotates with the gears. When the closing / opening lever 409 slides to the target position (such as the closing end point), the first pressure sensor 607 in the locking hole 32 is triggered by the locking block 606. The drive motor 608 drives the drive gear 602 to rotate slightly through the worm gear, pushing the locking block 606 to fully engage with the locking hole 32, mechanically locking the position.
[0071] The fixed bracket 603 synchronously displaces and contacts the second pressure sensor 610 on the side wall of the fixed box 31, triggering the indicator light 13 to illuminate (e.g., green light for closing, red light for opening), and the status is displayed on the control panel 12. When switching positions, the control panel 12 controls the drive motor 608 to reverse, causing the locking block 606 to disengage and the pressure signal to return to zero. This design completely avoids malfunctions or jumps during opening and closing, ensuring stable operation.
[0072] The overload protection component 5 (fuse 506, vacuum interrupter 503) monitors the current in real time. When the current is overloaded, the fuse 506 blows or the vacuum interrupter 503 activates, disconnecting the connection between the connector 502 and the output terminal 504, cutting off the circuit and preventing equipment damage.
[0073] The voltage comparator 701 of the low-voltage detection component 7 continuously monitors the voltage of the battery 401. If the voltage is lower than the threshold (e.g., undervoltage condition), the rotary motor 704 starts, driving the rotary tube 7022 to rotate, and the control plate 7023 slides along the thread in a direction away from the connecting rod 415. The preload of the anti-slip ring 7024 pushes the drive rod 7021 to extend into the docking groove 34.
[0074] The first threaded groove 33 of the drive rod 7021 mates with the second threaded groove 36, forcibly pulling the connecting rod 415 and the closing / opening lever 409 to perform the opening action (sliding downwards). Simultaneously, the sliding protrusion 408 of the second permanent magnet 407 slides into the second limit groove 35, ensuring the opening is complete. This process does not rely on the normal power supply of the closing / opening assembly 4, ensuring safe disconnection of the system in case of a fault.
[0075] In summary, the system achieves efficient commutation through a cellular modular design, while integrating overload protection, anti-pumping interlocking, and low-voltage detection functions. Specifically, the overload protection component 5 directly cuts off the overload current, with a response speed faster than traditional thermal relays; the anti-pumping interlocking component 6 uses a gear wedge mechanical locking mechanism, solving the problem of easy loosening of mechanical latches; and the low-voltage detection component 7 automatically forces tripping, overcoming the deficiency of traditional sensors that only alarm but do not act. Overall, this improves the stability, reliability, and safety of the power distribution system, making it suitable for high-demand electrical environments.
