Description

Technical Field

[0002] The number of ring network boxes used is increasing year by year. The power supply cabinet power supply line adopts three-phase four-wire power cable. A transformer needs to be installed for each phase of the cable to measure the voltage and current. The working principle of this type of sensor is usually based on the Hall effect or electromagnetic induction principle. By measuring the change of the magnetic field, they can indirectly measure the current or voltage in the cable. Specifically, the Hall effect sensor uses the interaction between the magnetic field and the current to generate a voltage proportional to the sensed current, and then this voltage is amplified and converted into an analog signal output. The electromagnetic induction sensor uses the change of the magnetic field generated when the current passes through the wire to sense the voltage signal, thereby indirectly measuring the current.

[0003] In the existing published technical literature, the Chinese patent publication number CN114527312A discloses a current and voltage sensor and a self-powered combined device, which outputs AC power through a second capacitor and a conversion module on a circuit board. The device is suitable for outdoor overhead transmission lines and can be used in conjunction with pole switches, feeder terminals, high-voltage meters and other equipment.

[0038] The method of using the intelligent voltage and current transmission sensor of the present invention is as follows:

[0039] Step 1: When transmitting voltage and current sensing, squeeze the silicone sleeve 13 onto the outer wall of the cable 14, and connect the external power supply line through the junction box 15. In this way, the current sensor 12 and the voltage sensor 1 can sense the voltage and current values ​​of the cable 14 after being energized. The sensed voltage and current values ​​are remotely transmitted to the background management computer through the wireless controller 23 and displayed on the background management computer. Once the voltage and current values ​​are abnormal, the maintenance personnel will be notified through the background to arrive at the site where the cable 14 is used.

[0040] Step 2, when the position change reminder is given, the wireless controller 23 is powered by the backup battery 21, and the wireless controller 23 starts the drive motor 6. The drive motor 6 drives the screw 5 to rotate forward, and the screw 5 rotates inside the slide frame 4. At the same time, the screw 5 carries the threaded sleeve block 7 to move to the left under the action of the thread transmission force, and the threaded sleeve block 7 slides to the left along the inner wall of the slide frame 4. The threaded sleeve block 7 carries the two linkage shafts 8 to move left synchronously, and the two linkage shafts 8 carry the two sleeve rods 9 to move respectively, and the sleeve rod 9 carries the hinge shaft 10 to move, and the hinge shaft 10 carries the sliding column 11 to slide inside the arc frame 3, and the distance between the two sliding columns 11 becomes larger. At the same time, the warning light 17 on the sliding column 11 is turned on to flash an alarm, and the buzzer 18 emits an abnormal alarm sound.

[0041] Restart the drive motor 6 to drive the screw 5 to rotate in the opposite direction. The screw 5 carries the threaded sleeve 7 to move right under the action of the thread transmission force. The threaded sleeve 7 carries the two linkage shafts 8 to move right. The two sleeve rods 9 respectively drive the two hinge shafts 10 to move right. The two hinge shafts 10 drive the two sliding columns 11 to slide right. The distance between the two sliding columns 11 becomes smaller, and the sliding column 11 carries the two slip rings 19 to slide on the arc frame 3. The two warning lights 17 and the two buzzers 18 can be displaced and moved to prevent other lines from blocking the warning lights 17 and the buzzers 18.

[0042] Step 3: When checking in time, the maintenance personnel presses the switch 24 with their finger after arriving at the scene, and recognizes the face through the face recognition camera 22. When the recognized value is the same as the value stored in the wireless controller 23, the drive shaft 39 is started through the transmission motor 40. The drive shaft 39 drives the driving gear ring 38 to rotate, and the driving gear ring 38 drives the driven gear ring 37 to rotate. The driven gear ring 37 drives the rotating shaft 34 to rotate. The rotating shaft 34 rotates inside the shaft ring 35. At the same time, the reinforcement block 36 provides support for the shaft ring 35. The rotating shaft 34 drives the switching shaft 31 to rotate, and the switching shaft 31 drives the arrival barcode 32 to rotate and dock to the barcode recognition sensor. 25 sensing position, after the barcode recognition sensor 25 recognizes the on-site barcode 32, the wireless controller 23 can send the barcode value of the maintenance personnel arriving at the site to the background computer to record the on-site time, and can timely check the maintenance personnel information and know in time when the maintenance personnel arrive at the site, and the switching shaft 31 carries the sensing shaft 28 to rotate inside the collar 27, and provides support force to the angle sensor 29 through the support block 30. When the angle sensor 29 senses one hundred and twenty degrees, the transmission motor 40 is turned off through the wireless controller 23, so that the warning light 17 and the buzzer 18 continue to alarm, prompting the maintenance personnel to deal with abnormal voltage and current values ​​in time.

[0043] Step 4: When eliminating the sensor, after the maintenance personnel have finished processing the abnormal voltage and current values, the maintenance personnel continue to press the switch 24 with their fingers, and at the same time, the face recognition camera 22 collects the face. After the wireless controller 23 recognizes the face correctly, the wireless controller 23 starts the transmission motor 40 to drive the drive shaft 39 to drive the drive gear ring 38 to rotate, the drive gear ring 38 drives the driven gear ring 37 to rotate, the driven gear ring 37 drives the rotating shaft 34 to rotate, the rotating shaft 34 drives the switching shaft 31 to rotate downward, and the switching shaft 31 carries the recovery barcode 33 to rotate to the barcode recognition sensor. The sensor 25 senses the position. After the barcode recognition sensor 25 recognizes the recovery barcode 33, the wireless controller 23 can send the barcode value eliminated by the maintenance personnel to the background computer, and record the time of eliminating the abnormal voltage and current values. When the voltage sensor 1 and the current sensor 12 sense the cable 14, the voltage and current values ​​are the same as the values ​​set by the wireless controller 23, the warning light 17 and the buzzer 18 can be turned off through the current sensor 12, so as to promptly urge the maintenance personnel to eliminate the abnormal fault of the cable 14 and eliminate the abnormal voltage and current sensing values ​​in time.
