Description

Technical Field

[0001] This disclosure relates to the field of electrical equipment technology, and in particular to an intelligent distribution box with arc fault detection. Background Technology

[0002] With the development of power electronics technology, various electrical devices are increasing. As a core component of power distribution and control, the operational safety of distribution boxes directly affects the stability of the entire power system. Traditional distribution boxes mainly rely on air switches for overload and short-circuit protection, but lack the specialized detection capability for arc faults. Arc faults (such as abnormal arcs caused by aging lines or poor contact) can easily generate high temperatures, potentially igniting surrounding insulation materials and causing fires. Traditional distribution boxes cannot identify such hazards in a timely manner. Existing distribution box fault detection largely relies on manual inspections. When a fault occurs, staff must check each item one by one, which cannot be done quickly and effectively, leading to prolonged fault handling time and further increasing electrical safety risks. Furthermore, the positions of wires and detection components in some distribution boxes are fixed. When the number of air switches or the wire layout in the distribution box are adjusted, the detection components cannot be flexibly adapted, resulting in limited detection applicability. Summary of the Invention

[0015] The technical solutions provided by the present disclosure may include the following beneficial effects: In this invention, through the threaded cooperation of the screw rod and the displacement plate driven by the first and second servo motors, two-dimensional precise positioning of the arc fault detector body is achieved, reducing detection omissions caused by position deviations of traditional fixed detection components; at the same time, after the detection is completed, the next wire can be detected without resetting the indicating block, shortening the overall detection cycle and improving the detection efficiency, especially suitable for the distribution box scenario with multiple wires. In this invention, through the structure in which the electric telescopic cylinder and the first spring in the contact component cooperate to drive the detection inductor to open and close, it can be automatically opened and sleeved on the wire; and the sliding adjustment of the X-displacement plate and the Y-displacement plate can adapt to the scenarios of increasing or decreasing the number of air switches and adjusting the wire layout in the distribution box, without disassembling or replacing the detection component, improving the adaptability of the distribution box to different power usage environments. In this invention, the indicating block in the jacked-up state can long-term mark the position of the faulty wire. Workers do not need to rely on real-time alarm signals and only need to observe the state of the indicating block to quickly lock all the fault points, avoiding the one-by-one detection process during the traditional distribution box fault troubleshooting, shortening the fault handling time; at the same time, the combination of the sound and light alarm and the physical indication double-reminds the workers, reducing the risk of fault omission.

[0019] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] like Figure 1-11 As shown in the figure, this disclosure proposes an intelligent distribution box with arc fault detection, including a distribution box body 1. Multiple air switches 2 are detachably installed inside the distribution box body 1, and wires 3 are fixedly connected to the load terminals of the multiple air switches 2. A frame 4 is fixedly connected to the four inner walls of the distribution box body 1. X-displacement plates 5 and Y-displacement plates 6 are slidably fitted between the longitudinal and transverse sides of the frame 4, respectively. The X-displacement plates 5 and Y-displacement plates 6 are intersecting and staggered. An arc fault detector body 7 is disposed at the intersection of the X-displacement plates 5 and Y-displacement plates 6. An alarm 10 is fixedly connected to the top of the outer side of the distribution box body 1. First travel grooves 11 are formed outwards on the inner walls of the two transverse sides of the frame 4. A first servo motor 12 is fixedly installed on the inner wall of one of the first travel grooves 11, and the output shaft of the first servo motor 12 is fixed... A first screw 13 is connected to the Y-displacement plate 6, which has a first threaded hole 17 on its end side inside one of the first stroke grooves 11. The two ends of the Y-displacement plate 6 are slidably fitted onto the inner walls of the first stroke grooves 11 on both sides of the frame 4, and the first screw 13 is threaded into the first threaded hole 17. The inner walls of both sides of the frame 4 have second stroke grooves 14 extending outwards. A second servo motor 15 is fixedly installed on the inner wall of one of the second stroke grooves 14, and the output shaft of the second servo motor 15 is fixedly connected to a second screw 16. A second threaded hole 18 is opened on the end side of the X-displacement plate 5 inside one of the second stroke grooves 14. The two ends of the X-displacement plate 5 are slidably fitted onto the inner walls of the second stroke grooves 14 on both sides of the frame 4, and the second screw 16 is threaded into the second threaded hole 18.

[0021] Understandably, when it is necessary to test the wire 3 at the load end of a specific air switch 2 within the distribution box body 1, the displacement adjustment system is activated: the first servo motor 12 within the first horizontal stroke groove 11 of the frame 4 drives the first screw 13 to rotate, utilizing the threaded engagement between the first screw 13 and the first threaded hole 17 at the end of the Y displacement plate 6, causing the Y displacement plate 6 to slide laterally along the first stroke groove 11; simultaneously, the second servo motor 15 within the second vertical stroke groove 14 of the frame 4 drives the second screw 16 to rotate, utilizing the threaded engagement between the second screw 16 and the second threaded hole 18 at the end of the X displacement plate 5, causing the X displacement plate 5 to slide longitudinally along the second stroke groove 14. Since the X displacement plate 5 and the Y displacement plate 6 are arranged in an intersecting and staggered configuration, the arc fault detector body 7 at their intersection moves precisely in a two-dimensional plane along with the sliding of the two displacement plates until it aligns with the position of the wire 3 to be tested, laying the positional foundation for subsequent contact testing.

[0022] In some embodiments, a contact assembly 8 is disposed on the side of the arc fault detector body 7 facing the interior of the distribution box body 1. The contact assembly 8 includes two sets of connecting blocks 801 fixedly connected to the back of the arc fault detector body 7. A connecting post 802 is fixedly connected to the rear side of each set of connecting blocks 801. A detection sensor 807 electrically connected to the arc fault detector body 7 is disposed at the rear end of each set of connecting posts 802. The detection sensor 807 cooperates with the wire 3. A first guide groove 19 is provided through one side of the X displacement plate 5. The connecting block 801 slides against the inner wall of the first guide groove 19. A first guide groove 19 is provided through one side of the Y displacement plate 6. A second guide groove 20 is provided, and the connecting post 802 slides against the inner wall of the second guide groove 20. Both sets of connecting posts 802 have fixed stops 803 at their rear ends. The connecting blocks 801 and connecting posts 802 are positioned front and rear, respectively, corresponding to the X-displacement plate 5 and Y-displacement plate 6. The arc fault detector body 7 is located in front of the X-displacement plate 5, and the stop 803 is located behind the Y-displacement plate 6. The X-displacement plate 5 and Y-displacement plate 6 are limited between the front of the stop 803 and the rear of the arc fault detector body 7. Both sets of stop 803 have fixed electric telescopic cylinders 804 at their rear ends. The two sets of electric telescopic cylinders 804 extend... A telescopic rod 805 is fixedly connected to the end of the telescopic shaft. A fixed frame 806 is fixedly connected to the ends of two sets of telescopic rods 805. A detection sensor 807 is disposed on the side of the fixed frame 806 near the wire 3. Each set of detection sensors 807 consists of two sensors, which are slidably fitted onto both sides of the inner wall of the fixed frame 806. Contacts 808 with circuit closing function are fixedly connected to opposite sides of the two detection sensors 807. After the contacts 808 of the two detection sensors 807 are connected, a space is left in the middle that fits around the wire 3. A first spring 809 is fixedly connected between one side of the detection sensor 807 and the inner wall of the fixed frame 806. The inner wall of the telescopic rod 805 is provided with a movable groove 810 that communicates with the inner wall of the fixed frame 806. Each pair of two detection sensors 807 is fixedly connected to one side with an L-shaped displacement frame 811 located in the movable groove 810. The inner walls of the opposite sides of the movable groove 810 are provided with through grooves 812 extending outward. The two L-shaped displacement frames 811 in each pair are staggered vertically, and the L-shaped displacement frame 811 slides in the through groove 812 with the transverse side of the telescopic rod 805. The end of the transverse side of the L-shaped displacement frame 811 that extends to the outside of the movable groove 810 is provided with a beveled block 813. The beveled side of the beveled block 813 abuts against the inner wall of the electric telescopic cylinder 804.During testing, the telescopic rod 805 retracts to the inner wall of the electric telescopic cylinder 804, and the inclined block 813 abuts and retracts into the movable groove 810. The L-shaped displacement frame 811 drives the two detection sensors 807 in the fixed frame 806 to open and compress the first spring 809. The electric telescopic cylinder 804 drives the telescopic rod 805 so that each set of two detection sensors 807 are located on both sides of the conductor 3. When the two detection sensors 807 are located on both sides of the conductor 3, the inclined block 813 disengages from the inner wall of the electric telescopic cylinder 804. The force of the first spring 809 causes the two detection sensors 807 to be clamped on the periphery of the conductor 3, and the contacts 808 of the two detection sensors 807 are connected to form a closed circuit, which can detect the current value of the conductor 3 and transmit it to the arc fault detector body 7 for display.

[0023] Understandably, after the arc fault detector body 7 is positioned, the contact assembly 8 enters the detection state: First, the connecting post 802 on the rear side of the connecting block 801 on the back of the arc fault detector body 7 synchronously drives the stop block 803 and the rear electric telescopic cylinder 804 to move near the conductor 3; then the electric telescopic cylinder 804 drives the telescopic rod 805 to retract, and the telescopic rod 805 drives the fixed frame 806 at the end to move closer to the electric telescopic cylinder 804. During this process, the inclined block 813 at the end of the L-shaped displacement frame 811 connected to the detection sensor 807 in the fixed frame 806 contacts and is pressed against the inner wall of the electric telescopic cylinder 804, and retracts along the through groove 812 into the movable groove 810, thereby... The L-shaped displacement frame 811 pulls the two detection sensors 807 apart (while compressing the first spring 809), forming an opening that can accommodate the wire 3. When the fixed frame 806 moves to both sides of the wire 3, the electric telescopic cylinder 804 drives the telescopic rod 805 to extend, the inclined block 813 is released from the constraint of the inner wall of the electric telescopic cylinder 804, the first spring 809 recovers its deformation, and pushes the two detection sensors 807 closer to each other until the inner contacts 808 are connected to form a closed circuit, and the wire 3 is sleeved in the space between the two detection sensors 807. At this time, the detection sensors 807 collect the current data of the wire 3 in real time and transmit the data to the arc fault detector body 7 for analysis.

[0024] In some embodiments, a display component 9 is disposed on the upper and lower sides of an X-displacement plate 5. The display component 9 includes circuit boards 901 disposed on both the upper and lower sides of the X-displacement plate 5. Multiple touch buttons 905 are fixedly connected to the side of each circuit board 901 facing the X-displacement plate 5. The touch buttons 905 are electrically connected to an alarm 10. Multiple indicator blocks 907 corresponding to the touch buttons 905 are disposed on both the upper and lower sides of the X-displacement plate 5. Limit frames 902 are fixedly connected to both sides of the upper and lower sides of the X-displacement plate 5. Two circuit boards 901 are fixedly connected to... A limiting block 903 slides on the inner wall of the limiting frame 902. A second spring 904 is fixedly connected between one side of the limiting block 903 and the inner wall of the limiting frame 902. Multiple sets of Chinese character-shaped grooves 906 are opened through the upper and lower sides of the X-displacement plate 5. Each set of Chinese character-shaped grooves 906 consists of two grooves, corresponding to two sets of connecting blocks 801. A first guide groove 19 is opened through the middle of the X-displacement plate 5, dividing it into upper and lower parts. The Chinese character-shaped grooves 906 are respectively opened in the upper and lower parts of the X-displacement plate 5. One side of the upper and lower parts of the X-displacement plate 5 has an inward opening corresponding to the Chinese character-shaped groove 906. A series of six interconnected displacement grooves 908 are provided. Multiple displacement blocks 909 are slidably fitted onto the inner wall of each displacement block 908. A third spring 910 is fixedly connected between one side of each displacement block 909 and the inner wall of the displacement groove 908. Each displacement block 909 corresponds to an indicator block 907. A positioning disk 911 is fixedly connected to the bottom of each indicator block 907. The positioning disk 911 slidably fits onto the inner wall of the larger groove of the T-shaped groove 906. The indicator block 907 slidably fits onto the inner wall of the smaller groove of the T-shaped groove 906. The side of each displacement block 909 facing the indicator block 907 is an arc-shaped block. 912; wherein, the arc edge of the arc block 912 abuts against the periphery of the positioning disk 911, and the upper and lower sides of the two sets of connecting blocks 801 are provided with mounting grooves 913, and the bottom walls of the two mounting grooves 913 are fixedly connected with electric push rods 914 electrically connected to the arc fault detector body 7, and one end of the telescopic shaft of the electric push rod 914 is fixedly connected with a push block 915; wherein, the mounting grooves 913 of the two sets of connecting blocks 801 correspond to each set of two T-shaped grooves 906 and are on the same central axis, and the push block 915 is located in the T-shaped groove 906 and abuts against the end face of the positioning disk 911.

[0025] It should be noted that if the arc fault detector body 7 detects an anomaly in the current data analysis (consistent with the current fluctuation characteristics of an arc fault), an alarm mechanism is immediately triggered: On one hand, the electric push rod 914, which is electrically connected to the arc fault detector body 7 in the mounting slot 913 of the connecting block 801, is activated, pushing the push block 915 to move along the U-shaped slot 906 of the X displacement plate 5. The push block 915 presses against the positioning disk 911, causing the indicator block 907 on the top of the positioning disk 911 to move towards the circuit board 901 until the indicator block 907 touches the corresponding touch button 905 on the circuit board 901. When the touch button 905 is triggered, the alarm 10 on the top of the outer side of the distribution box body 1, which is electrically connected to it, emits an audible and visual alarm signal. On the other hand, during the process of the indicator block 907 being lifted, the positioning disk 911 contacts the arc edge of the arc block 912 of the displacement block 909 in the displacement groove 808, pushing the displacement block 909 to move outward from the displacement groove 808. After the positioning disk 911 moves above the displacement block 909, the displacement block 909 is reset under the action of the third spring 910, forming a limit on the positioning disk 911, keeping the indicator block 907 in the lifted state, and accurately marking the position of the faulty wire 3.

[0026] Working principle: When using the device, if arc fault detection is required on the conductor 3 at the load end of a specific air switch 2 within the distribution box body 1, the detection component is first precisely positioned by displacement adjustment. The first servo motor 12 in the first horizontal stroke groove 11 of the frame 4 drives the first screw 13 to rotate. With the first screw 13 threadedly engaging with the first threaded hole 17 of the Y displacement plate 6, the Y displacement plate 6 slides laterally along the first stroke groove 11. Simultaneously, the second servo motor 15 in the second vertical stroke groove 14 of the frame 4 drives the second screw 16 to rotate. With the second screw 16 threadedly engaging with the second threaded hole 18 of the X displacement plate 5, the X displacement plate 5 slides longitudinally along the second stroke groove 14. Because the X displacement plate 5 and the Y displacement plate 6 intersect and are staggered, the arc fault detector body 7 at the intersection moves to the corresponding position of the conductor 3 to be detected with the two-dimensional sliding. Then, the contact component 8 is activated to complete the conductor current detection and arc fault identification. The connection block 801 on the back of the arc fault detector body 7 connects to the corresponding position of the conductor 3 to be detected. The connecting column 802 drives the stop block 803 and the rear electric telescopic cylinder 804 to move synchronously. The electric telescopic cylinder 804 first drives the telescopic rod 805 to retract, causing the telescopic rod 805 to move the fixed frame 806 closer to the electric telescopic cylinder 804. At this time, the inclined block 813 at the end of the L-shaped displacement frame 811 abuts against the inner wall of the electric telescopic cylinder 804. The inclined block 813 is pressed and retracts along the through groove 812 into the movable groove 810. The L-shaped displacement frame 811 pulls the two detection sensors 8 in the fixed frame 806. 07. The first spring 809 is opened and compressed. After the fixed frame 806 moves to both sides of the wire 3, the electric telescopic cylinder 804 drives the telescopic rod 805 to extend. The inclined block 813 is separated from the inner wall of the electric telescopic cylinder 804. The first spring 809 returns to its deformation and pushes the two detection sensors 807 to approach each other until the inner contact 808 is connected to form a closed circuit and the wire 3 is sleeved in the middle space. The detection sensor 807 collects the current data of the wire 3 in real time and transmits it to the arc fault detector body 7.If an abnormal current is detected (consistent with arc fault characteristics), the arc fault detector body 7 triggers an alarm signal. At this time, the electric push rod 914, which is electrically connected to the arc fault detector body 7 in the mounting slot 913 of the connecting block 801, is activated, pushing the push block 915 to move along the U-shaped slot 906 of the X displacement plate 5. The push block 915 presses against the positioning plate 911, causing the indicator block 907 to move towards the circuit board 901 until the indicator block 907 touches the corresponding touch button 905 on the circuit board 901. After the touch button 905 is triggered, the alarm 10 on the top of the outer side of the distribution box body 1, which is electrically connected to it, emits an alarm signal, and the indicator block 907... Position 07 precisely corresponds to the location of the faulty wire 3. The positioning disk 911 below the lifted indicator block 907 abuts against the arc edge of the arc block 912 on the displacement block 909, pushing it outward so that the positioning disk 911 is above the displacement block 909. At the same time, the displacement block 909 is reset by the third spring 910. At this time, the wire 3 corresponding to the arc fault on the indicator block 907 is in the lifted state. The arc fault detector body 7 can continue to detect the subsequent wires 3 until all wires 3 have been detected. The operator can clearly identify the wire 3 with the arc fault through the lifted indicator block 907 on the X displacement plate 5.
