[0002] Ninety percent of fault information in a power distribution network exists in the form of high-frequency traveling waves, but because the sampling accuracy of traditional monitoring equipment is insufficient (usually less than 10 kHz), these data have been in a "invisible" state for a long time, and therefore need to be broken through by using a power distribution network traveling wave fault early warning and positioning device. With the continuous development of power systems, the scale and complexity of power distribution networks are increasing, and fault early warning and positioning have become an important link to ensure the stable operation of power systems. The power distribution network traveling wave fault early warning and positioning device, as a newly emerging technical means in recent years, plays an increasingly important role in operation and inspection work. The traveling wave fault early warning and positioning device is mainly used for real-time monitoring of fault traveling wave signals in power lines, and realizes early warning and positioning of faults through analysis of the traveling wave signals. The device has the characteristics of real-time, accuracy and reliability, and can effectively improve the efficiency of power system fault diagnosis.

[0004] Although the above application and the prior art can ensure that the traveling wave sensor is more closely connected with the cable and reduce the hysteresis existing in the manual maintenance process, when the above application and the prior art are used for fault prediction and positioning of the cable, when the cable is in an inclined state and encounters rainy weather, rainwater will flow along the cable to the inside of the device, and the rainwater forms a conductive water film, which affects the use effect of the traveling wave sensor, and when the conductive water film is removed, because there is grease on the surface of the cable, when the rainwater contacts the grease, an emulsion layer is formed, so when the conductive water film is removed, the emulsion layer becomes more serious, thereby affecting the use of the traveling wave sensor, and after the conductive water film is removed, the rainwater remains on the surface of the removal object, when the rainwater is removed, the rainwater still remains on the surface of the cable, and then flows to the contact surface of the cable and the traveling wave sensor, thereby causing the traveling wave sensor to issue an incorrect alarm and positioning, therefore the application provides a distribution network traveling wave fault early warning and positioning device based on an intelligent power distribution system.

[0058] Specific embodiment four, please refer to Figures 1-2 , according to the power distribution network traveling wave fault early warning and positioning device based on the intelligent power distribution system provided in specific embodiment three, the further technical solutions are provided in the embodiment:

[0059] The anti-disability component 4 includes an L-shaped rack 41 fixedly connected to the top and bottom of the drive box 22 and a rotating rod 42 rotatably connected to the lower shell 1 and the upper shell 13. The surface of the rotating rod 42 is fixedly connected to a driving gear 421 and a storage wheel 422. The driving gear 421 is meshed with the L-shaped rack 41 for transmission. A pull rope 423 is provided on the surface of the storage wheel 422. The anti-disability component 4 also includes an iron plate 44 slidably connected to the inside of the fixed cylinder 221 and two guide rods 43 rotatably connected to the inside of the upper shell 13 and the lower shell 1. One end of the iron plate 44 is fixedly connected to the inside of the fixed cylinder 221 with a first spring 441, and the end of the iron plate 44 close to the first spring 441 is away from the storage wheel 4 with the pull rope 423. 22 is fixedly connected, one end of the iron disk 44 is away from the first spring 441 and is magnetically attracted with a magnetic disk 442, one end of the magnetic disk 442 away from the iron disk 44 is fixedly connected to one end of the extension rod 222, and one end of the magnetic disk 442 away from the iron disk 44 is fixedly connected to the inside of the fixed cylinder 221 with a second spring 443, the anti-disability component 4 also includes two extrusion frames 45 arranged inside the upper shell 13 and the lower shell 1, the ends of the two extrusion frames 45 away from the drive box 22 are fixedly connected to the support rod, the support rod is fixedly connected to one end of the inner wall of the upper shell 13 and the lower shell 1, the interiors of the two extrusion frames 45 are fixedly connected with an extrusion ring 451, and a moving groove for the extrusion frame 45 to move is provided on one side of the drive box 22;

[0060] It should be noted that the surface of the extrusion frame 45 is fixedly connected to a water outlet pipe, and the bottom of the lower shell 1 is provided with a flow hole;

[0061] When it is necessary to prevent the squeezed-out water from contacting the cable again, after the absorbent sponge 224 absorbs the conductive water film on the surface of the cable, the drive motor 21 is used to control the drive screw 211 to reverse, so that the drive screw 211 drives the drive box 22 to move toward one end of the drive motor 21 through the drive screw block 212. When the drive box 22 moves to the middle of the lower shell 1, the pull rope 423 is in a straight state. When the drive box 22 continues to move toward one end of the drive motor 21, the drive box 22 drives the drive gear 421 to rotate through the L-shaped rack 41, so that the rotating rod 42 recycles the pull rope 423 through the storage wheel 422. When the pull rope 423 is recycled, the pull rope 423 drives the pull rope 423 to retract through the iron The disk 44 and the magnetic disk 442 drive the extension rod 222 to retract, thereby causing the fixed plate 223 to drive the water-absorbing sponge 224 to retract, and then when the extrusion frame 45 enters the interior of the drive box 22, the water-absorbing sponge 224 is not in contact with the extrusion ring 451. When the pull rope 423 squeezes the first spring 441 to the limit through the iron disk 44, the iron disk 44 and the magnetic disk 442 are separated from each other, thereby causing the second spring 443 to drive the extension rod 222 to retract quickly through the magnetic disk 442, so that the extension rod 222 drives the water-absorbing sponge 224 to contact and squeeze the extrusion ring 451 through the fixed plate 223, so that the water inside the water-absorbing sponge 224 is quickly squeezed out, and then the squeezed water no longer contacts the cable.

[0062] Working principle: in use, the lower shell 1 and the upper shell 13 are installed at the specified position, and the traveling wave sensor 11 is in contact with the cable. When the fault information of the cable needs to be warned and located, the traveling wave sensor 11 is in contact with the high-frequency traveling wave, and the position of the fault is signaled and warned through the traveling wave sensor 11. Through the background display, the fault can be quickly located and processed. When the conductive water film formed on the surface of the cable needs to be removed, the driving motor 21 is started after the rain sensor senses that the lower shell 1 is filled with water. The driving motor 21 drives the driving screw 211 to move the driving screw block 212, which drives the fixed cylinder 221 to move through the driving box 22. Since the water-absorbing cotton 224 is in contact with the cable, when the fixed cylinder 221 moves, the fixed cylinder 221 drives the fixed plate 223 to move through the extension rod 222, so that the fixed plate 223 drives the water-absorbing cotton 224 to move on the surface of the cable, and then the water-absorbing cotton 224 absorbs the conductive water film on the surface of the cable, so that the surface of the cable no longer exists. The conductive water film, so it does not affect the use of the traveling wave sensor 11. When the emulsified layer needs to be prevented from being intensified to affect the use of the traveling wave sensor 11, when the driving screw block 212 moves, the driving screw block 212 drives the push rod 31 to move, and the push rod 31 drives the extrusion plate 311 to move in the emulsion removal tank 32, so that the emulsion removal agent in the emulsion removal tank 32 enters the annular disc 33 through the flow guide pipe 322. When the annular disc 33 is filled with emulsion removal agent, the emulsion removal agent sprays the emulsion layer on the surface of the cable through the nozzle 331, and then processes the emulsion layer. At the same time, the driving box 22 drives the annular disc 33 to move through the support block 330 when it moves, so that the annular disc 33 drives the scraping ring 334 to move through the extension cylinder 332 and the support plate 333. The scraping ring 334 scrapes the processed emulsion layer when it moves, so that the emulsion layer no longer adheres to the surface of the cable. Therefore, when the water-absorbing cotton 224 absorbs the conductive water film, the water-absorbing cotton 224 will not rub the emulsion layer, thereby preventing the emulsion layer from being intensified. When the squeezed water needs to be prevented from contacting the cable again, after the water-absorbing cotton 224 absorbs the conductive water film on the surface of the cable, the driving motor 21 controls the driving screw 211 to reverse, so that the driving screw 211 drives the driving box 22 to move towards one end of the driving motor 21 through the driving screw block 212. When the driving box 22 moves to the middle of the lower shell 1, the pull rope 423 is in a straight state. When the driving box 22 continues to move towards one end of the driving motor 21, the driving box 22 drives the driving gear 421 to rotate through the L-shaped rack 41, so that the rotating rod 42 recovers the pull rope 423 through the storage wheel 422. When the pull rope 423 is recovered, the pull rope 423 drives the extension rod 222 to retract through the iron disc 44 and the magnetic disc 442, so that the fixed plate 223 drives the water-absorbing cotton 224 to retract, and then when the extrusion frame 45 enters the driving box 22,The water-absorbing cotton 224 is not in contact with the pressing ring 451. When the pull rope 423 presses the first spring 441 to the limit through the iron disc 44, the iron disc 44 and the magnetic disc 442 are separated from each other, so that the second spring 443 drives the extension rod 222 to retract quickly through the magnetic disc 442, and the extension rod 222 drives the water-absorbing cotton 224 to contact and press the pressing ring 451 through the fixed plate 223, so that the water in the water-absorbing cotton 224 is quickly pressed out, and then the pressed-out water no longer contacts the cable, thereby not affecting subsequent use.
