Description

Technical Field

[0001] This utility model relates to the field of power grid management technology, and in particular to an intelligent operation and maintenance management device for predicting power grid faults. Background Technology

[0002] A power grid is the entire system comprised of substations and transmission and distribution lines of various voltages within a power system. It includes three units: substation, transmission, and distribution. The power grid's task is to transmit and distribute electrical energy and change voltage. A smart operation and maintenance management device for power grid fault prediction is a hardware and software system integrating sensors, data acquisition, artificial intelligence algorithms, and communication technologies. It is mainly used to monitor the real-time operating status of power grid equipment, predict potential fault risks by analyzing historical and real-time data, and issue early warnings or diagnostic information. This guides maintenance personnel to conduct targeted preventative maintenance or rapid repairs, effectively reducing unexpected power outages, extending equipment lifespan, and lowering operation and maintenance costs.

[0003] Existing intelligent operation and maintenance management devices for power grid fault prediction typically connect copper wires directly to the device's conductive interface by welding. This welding process inside the device may damage other electronic components, and subsequent maintenance and disassembly of the welded copper wires are too cumbersome. As a result, after the power grid fault prediction system detects a line fault, the staff cannot perform efficient intervention and maintenance, thus reducing work efficiency. Utility Model Content

[0009] In a preferred embodiment, limit holders are respectively provided on the outer sides of the plurality of fixed ring seats. A plurality of rotating plates, equally spaced on the fixed ring seats, are located inside corresponding placement slots on the limit holders. The inner walls of the fault detection chamber on both sides away from the plurality of copper wires are respectively provided with equally spaced moving slots.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] The intelligent operation and maintenance management device for power grid fault prediction disclosed in this utility model is mainly applied to scenarios where existing power grid fault prediction devices directly solder copper wires to conductive interfaces. This internal soldering method is prone to damaging electronic components and makes subsequent maintenance and disassembly difficult, reducing the maintenance efficiency of staff when line faults occur.

[0020] Reference Figures 1-4An intelligent operation and maintenance management device for predicting power grid faults includes: a cabinet 1, a rotating cabinet door 5 on one side of the cabinet 1, a display screen 4 on one side of the rotating cabinet door 5, a fault detection chamber 10 fixedly connected to the inner wall of the cabinet 1, a power supply 11 on the lower inner wall of the cabinet 1, and the fault detection chamber 10 located above the power supply 11; an alarm 2 located on the upper side of the cabinet 1; multiple wire sheaths 6, divided into two groups, passing through both sides of the cabinet 1 at equal intervals and abutting against both sides of the fault detection chamber 10, each wire sheath 6 containing copper wires 16, the two groups of copper wires 16 being equally spaced inside both sides of the fault detection chamber 10; and quick-release fixing components 15, each quick-release fixing component 15 welded to the outer wall of the corresponding copper wire 16, located inside the fault detection chamber 10, and used for quick installation, fixing, and removal of the copper wires 16 for maintenance.

[0021] Reference Figures 1-5 In a preferred embodiment, the quick-release fixing assembly 15 includes: a fixing ring seat 1504, multiple fixing ring seats 1504 are respectively welded to the outer wall of the corresponding copper wire 16, the outer wall of the fixing ring seat 1504 is provided with rotating grooves at equal intervals, and fixing rods 1510 are fixedly connected inside the multiple rotating grooves; a rotating clamping plate 1501, multiple rotating clamping plates 1501 are respectively connected to the outer wall of the corresponding fixing rod 1510 through bearings, and one end of two torsion springs 1502 are fixedly connected to both sides of the multiple rotating clamping plates 1501, the other end of the two torsion springs 1502 are fixedly connected to the inner walls of the two ends of the corresponding rotating grooves, and the two torsion springs 1502 are sleeved on the outer wall of the corresponding fixing rod 1510.

[0022] In this solution, the quick-release fixing assembly 15 further includes: a connecting tube 1509, which is fixedly connected to one side of the fixing ring seat 1504. The connecting tube 1509 is sleeved on the outer wall of the copper wire 16. A sliding ring seat 1506 is fixedly connected to the side of the connecting tube 1509 away from the fixing ring seat 1504. The sliding ring seat 1506 is sleeved on the outer wall of the copper wire 16. A locking ratchet plate 1507 is slidably connected at equal intervals to the sliding holes opened at equal intervals on both sides of the sliding ring seat 1506. Racket blocks are provided at equal intervals on the upper side of the locking ratchet plate 1507. One end of a plurality of compression springs 1505 is fixedly connected at equal intervals on the lower side of the locking ratchet plate 1507. The other end of the plurality of compression springs 1505 is fixedly connected to the inner wall of the sliding ring seat 1506.

[0023] In this solution, the quick-release fixing assembly 15 further includes: a rotating ratchet ring 1503, which is slidably connected to the sliding groove opened in the outer wall of the sliding groove ring seat 1506, and ratchet blocks are equally spaced on the inner wall of the rotating ratchet ring 1503, which engage with ratchet blocks on multiple locking ratchet plates 1507; and support plates 1508, one end of multiple support plates 1508 is equally spaced and fixedly connected to the side of the rotating ratchet ring 1503 near the fixing ring seat 1504, and the other end of multiple support plates 1508 abuts against one side of the corresponding rotating locking plate 1501.

[0024] During the installation of the copper wire 16, the multiple rotating plates 1501 rotate against the torsion spring 1502 under the action of the limiting bracket 14 until both sides of the multiple rotating plates 1501 abut against the corresponding slots of the limiting bracket 14 and one side of the multiple support plates 1508. At the same time, under the action of the conductive plate 18 and the telescopic spring 17, the quick-release fixing assembly 15, along with the copper wire 16, is tightly fixed to the limiting bracket 14, realizing the quick installation of the copper wire 16. Under the action of the telescopic spring 17, the conductive plate 18 always keeps the conductive interface 22 tightly abutting against the front end of the copper wire 16, thereby ensuring normal power supply and fault detection. The welding process is carried out outside the device, and the copper wire 16 is not directly welded to the device to avoid damage to other electronic components caused by welding inside the device. By rotating the ratchet ring 1503, the multiple support plates 1508 and the corresponding rotating plates 1501 fixed to it are no longer on the same horizontal line, thereby canceling the support limit on the rotating plates 1501. Then, the wire is pulled directly, and the multiple rotating plates 1501, under the action of the limit plate seat 14, overcome the force of the torsion spring 1502 and rotate towards the sliding ring seat 1506. Thus, the operator can easily pull the wire out of the cabinet 1, improving work efficiency.

[0025] Reference Figures 1-6In a preferred embodiment, limiting slots 14 are respectively provided on the outer sides of multiple fixed ring seats 1504. Multiple rotating plates 1501, equally spaced on the fixed ring seats 1504, are located inside the corresponding placement slots opened on the limiting slots 14. The inner walls of the fault detection chamber 10 away from the multiple copper wires 16 are respectively provided with moving slots at equal intervals. Conductive plates 18 are slidably connected inside the two sets of opposite moving slots on the same horizontal line. A conductive interface 22 is provided on the side of the multiple conductive plates 18 near the corresponding copper wire 16. One end of the multiple copper wires 16 abuts and connects with the corresponding conductive interface 22. The same conductive rod 20 is slidably connected inside each pair of opposite conductive plates 18. A heat insulation cylinder 21 is provided on the outer wall of the multiple conductive rods 20. The part of the heat insulation cylinder 21 that contacts the conductive rod 20 is made of rubber. The two ends of the multiple conductive plates 18 are respectively... A rubber shell 19 is fixedly connected to the fault detection chamber 10. Multiple fixing blocks 13 are fixedly connected at equal intervals to the inner walls of the two sides away from the multiple copper wires 16. The multiple fixing blocks 13 are fixedly connected to the corresponding rubber shells 19 by extension springs 17. Temperature detectors 12 are set at equal intervals on the side of the fault detection chamber 10 away from the multiple copper wires 16. The probe ends of the multiple temperature detectors 12 pass through the outer wall of the corresponding heat insulation cylinder 21 and contact the outer wall of the corresponding conductive rod 20. A heat insulation plate 7 is fixedly connected to the inner wall of the cabinet 1. The heat insulation plate 7 is located on the upper side of the fault detection chamber 10. A data acquisition unit 8, a data transmission unit 9, and a remote control unit 3 are respectively set on the upper side of the heat insulation plate 7. The data transmission unit 9 is located between the data acquisition unit 8 and the remote control unit 3. The signal end of the remote control unit 3 passes through the cabinet 1 and is located outside the cabinet 1.

[0026] During fault detection, the conductive plate 18 keeps the conductive interface 22 tightly pressed against the front end of the copper wire 16 under the action of the extension spring 17, thus ensuring normal power supply and fault detection. In addition, the heat insulation plate 7 prevents the high temperature of the fault detection chamber 10 from affecting the normal operation of the electronic components on it.

[0027] Working principle: The operator first cuts both ends of the wire. After cutting, a portion of the insulation 6 on the cut ends of the two wires is removed to expose the copper wire 16 inside. Then, two quick-release fixing components 15 are fitted onto the outer wall of the corresponding copper wire 16. The fixing ring 1504 inside the quick-release fixing component 15 is then welded to the outer wall of the corresponding copper wire 16. After welding, the wire is inserted into the opening on one side of the cabinet 1. Then, the copper wire 16 with the quick-release fixing component 15 welded on it is passed through the limiting hole opened on the fault detection compartment 10. Under normal circumstances, the rotating plates 1501, which are evenly spaced on the fixing ring 1504, rotate away from the corresponding torsion spring 1502. One end of the sliding ring seat 1506 allows the copper wire 16 to smoothly enter the interior of the fault detection chamber 10 during this process. Simultaneously, the front end of the copper wire 16 contacts the interior of the conductive interface 22, and as the copper wire 16 enters, the conductive plate 18 overcomes the action of the telescopic spring 17 and slides along the moving groove. Once the copper wire 16 is fully inside the fault detection chamber 10 and the multiple rotating plates 1501 have exceeded the limit seat 14, the wire is slowly pulled backward. Under the action of the limit seat 14, the multiple rotating plates 1501 overcome the action of the torsion spring 1502 and rotate until both sides of the multiple rotating plates 1501 abut against the corresponding slots of the limit seat 14 and one side of the multiple support plates 1508. At the same time, the conductive plate 18 slides along the moving groove against the action of the telescopic spring 17. Under the action of the conductive plate 18 and the telescopic spring 17, the quick-release fixing assembly 15, along with the copper wire, is tightly fixed to the limiting bracket 14, enabling the rapid installation of the copper wire 16. Furthermore, under the action of the telescopic spring 17, the conductive plate 18 always keeps the conductive interface 22 tightly abutting against the front end of the copper wire 16, thus ensuring normal power supply and fault detection. Simultaneously, all welding work is performed outside the device, and the copper wire 16 is not directly welded to the device to avoid potential damage to other electronic components from welding inside the device. After this wire is installed, the previous work is repeated, connecting the remaining wires to the other holes in the device. After all wires are connected and connected, the operator opens all the equipment inside the cabinet 1, and the power supply 11 is activated. Power is supplied. At this time, the temperature detector 12 detects the surface temperature of the part of the conductive rod 20 located inside the heat insulation cylinder 21 in real time through its probe. The detected data is collected by the data acquisition unit 8 and transmitted to the display screen 4 through the data transmission unit 9. The staff can see the temperature changes of each temperature detector 12 displayed on the display screen 4. If the temperature detector 12 detects that the temperature of the conductive rod 20 exceeds the normal set temperature, it will then transmit the data to the data acquisition unit 8, and then the data acquisition unit 8 will transmit it to the remote control unit 3 through the data transmission unit 9. The remote control unit 3 will then send the data to the terminal and immediately activate the alarm 2 to notify the staff to come and check.When removing the copper wire 16, the worker only needs to rotate the ratchet ring 1503 to disengage the multiple support plates 1508 and the corresponding rotating clamping plates 1501 fixedly connected to it from the same horizontal line, thereby canceling the support limit on the rotating clamping plates 1501. Then, by directly pulling the wire, the multiple rotating clamping plates 1501, under the action of the limiting clamping seat 14, overcome the force of the torsion spring 1502 and rotate towards the sliding ring seat 1506. Thus, the worker can easily pull the wire out of the cabinet 1, improving work efficiency.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
