Description

Technical Field

[0001] The present invention relates to the technical field of power system fault detection, in particular to a power system fault detection method and device. Background Art

[0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power distribution stations and power consumption. Its function is to convert primary energy from nature into electric energy through power generation devices, and then supply electric energy to each household through transmission, transformation and distribution. During the normal operation of the power system, if the transmission line fails, it will directly affect the safe and reliable operation of the line, and in serious cases, it will cause large-scale power outages. In the cold winter, the line will be covered with ice, and de-icing is required before maintenance, and then the transmission line can be inspected.

[0003] At present, the traditional de-icing method before line fault detection is to manually use a cleaning tool made of a long pole to sweep or knock back and forth under the line to achieve the purpose of de-icing. Not only is the operation efficiency low, but there are also major safety hazards. In addition, there are also de-icing operations using de-icing machines, but traditional de-icing machines mostly use metal de-icing rings to slide along the surface of the line to achieve the purpose of de-icing. During the de-icing process, ice cubes can easily get stuck in the gap between the metal de-icing ring and the line and freeze, which will reduce its de-icing effect and affect the results of subsequent line maintenance.

It can then be wiped, thus solving the problem that traditional de-icing machines do not de-ice thoroughly enough and are prone to jamming during the de-icing process, resulting in low de-icing efficiency, thereby ensuring the accuracy of subsequent line maintenance.

A driving pulley 24 is fixedly installed in the middle of the driving shaft 22. Driven pulleys 26 are symmetrically arranged on the left and right sides of the driving pulley 24. The driven pulley 26 and the driving pulley 24 are connected by an annular belt 27. The driven pulley 26 is fixedly installed in the middle of the transmission shaft 25.

[0043] During specific operation, the ice crystals at the end of the line are first knocked off manually, and then the movable rod 34 is pulled to the front and rear sides respectively. At this time, the positioning spring 33 is compressed, and the movable wheel 35 will move away from the fixed wheel 37. Then, the fault detection device of the power system is manually installed on the line so that the line is located between the movable wheel 35 and the fixed wheel 37. Then, the movable rod 34 is released. At this time, the reaction force of the positioning spring 33 will drive the movable wheel 35 to move toward the fixed wheel 37, thereby tightening the line, starting the drive motor 21, and driving the drive shaft 22 to rotate through the drive motor 21, thereby driving the drive pulley 24 to rotate. Under the action of the annular belt 27, the driven pulley 26 and the transmission shaft 25 will also rotate synchronously. Under the action of the second bevel gear 38, the fixed rod 36 and the fixed wheel 37 will rotate, thereby driving the entire fault detection device to move along the line. Example

[0044] The technical solution is basically the same as that of the first embodiment, see Figure 1 , Figure 2 as well as Figures 4 to 7 The difference is that a knocking assembly 4 is symmetrically arranged on the right side wall of the detection box 1, the left end of the knocking assembly 4 is connected with the positioning assembly 3, and a deicing assembly 5 is arranged near the right side of the lower end surface of the detection box 1.

[0045] The knocking assembly 4 includes a gear shaft 42, which is symmetrically installed on the right side wall of the box body 11. A third bevel gear 41 is fixedly arranged on the left end of the gear shaft 42, and the third bevel gear 41 and the second bevel gear 38 are meshed with each other. A knocking plate 43 is fixedly connected to the right end of the gear shaft 42, and rubber strips 44 are evenly arranged on the circumferential side walls of the knocking plate 43.

[0046] The de-icing assembly 5 includes a vertical plate 51, and the vertical plate 51 is symmetrically installed at the front and rear positions near the right side of the lower end surface of the detection box 1. The middle part of the lower end of the vertical plate 51 is semi-arc-shaped, and a mounting hole is provided at the lower end of the vertical plate 51 and above the semi-arc. The hollow conical de-icer 52 is fixedly installed on the right side wall of the vertical plate 51 by the mutual cooperation of fastening bolts and the mounting holes. A wiping unit 53 is arranged at the middle part of the driving assembly 2 near the front and rear ends, and an air blowing unit 54 is arranged on the outer side of the wiping unit 53. The right side of the air blowing unit 54 extends to the left side of the hollow conical de-icer 52.

[0047] The wiping unit 53 includes a cam 531, which is fixedly installed on the driving shaft 22 near the end. A T-shaped rod 532 is slidably installed below the cam 531, and a coil spring 533 is sleeved on the T-shaped rod 532. A sliding rod 534 is symmetrically penetrated at the lower end of the T-shaped rod 532, and a wiping liner 535 is penetrated and installed on the sliding rod 534. The wiping liner 535 is arranged in pairs and a sponge block 536 is fixedly installed on the inner wall thereof.

[0048] The air blowing unit 54 includes a heater 541, and the heater 541 is distributed in a rectangular array at the bottom of the box 11. An elastic air bag 542 is arranged on the outside of the coil spring 533. The lower end of the right side wall of the elastic air bag 542 is connected to an air guide tube 543. The lower end of the air guide tube 543 extends to the bottom of the box 11 and is fixedly installed with an arc-shaped air storage device 544. Air nozzles 545 are evenly installed on the right side wall of the arc-shaped air storage device 544.

[0049] One thing that needs to be explained is that the hollow cone de-icers 52 are arranged in pairs. During the installation of the fault detection device of the power system, the hollow cone de-icers 52 will be manually installed on the vertical plate 51. The opposite side of the lower end of the wiping lining 535 is a magnetic structure, and the upper end of the wiping lining 535 can rotate around the slide rod 534. After the installation of the hollow cone de-icer 52 is completed, the wiping lining 535 will be manually installed to the outside of the line and its lower end will be magnetically attracted, and the sponge block 536 will fit tightly against the surface of the line.

[0050] During specific operation, the second bevel gear 38 will also drive the third bevel gear 41 to rotate during the rotation process, thereby driving the gear shaft 42, the knocking plate 43 and the rubber strip 44 to rotate. The rubber strip 44 will continuously knock the line during the rotation process, thereby preliminarily breaking the ice crystals that have already formed on the line, which is convenient for subsequent deicing operations. Subsequently, the hollow truncated cone deicer 52 will shovel off the ice crystals that were preliminarily broken in the previous step during the movement process.

[0051] The driving shaft 22 will also drive the cam 531 to rotate during the rotation process, thereby driving the T-shaped rod 532 to move downward, and the elastic airbag 542 will also be compressed, and the air inside the elastic airbag 542 will enter the arc-shaped air storage tank 544 through the air guide pipe 543, and finally blow to the inside of the hollow truncated cone de-icer 52 through the air nozzle 545, so as to blow out the solid ice in the gap between the hollow truncated cone de-icer 52 and the line, and prevent the hollow truncated cone de-icer 52 from getting stuck. The outgoing air flow has a certain temperature, thereby further improving the efficiency of blowing out the solid ice; when the T-shaped rod 532 moves downward, the coil spring 533 is compressed, and the sliding rod 534, the wiping liner 535 and the sponge block 536 are driven to move downward through the T-shaped rod 532. When the T-shaped rod 532 moves upward, the reaction force of the coil spring 533 will drive the sliding rod 534, the wiping liner 535 and the sponge block 536 to move upward, and so on and so forth, thereby wiping the surface of the line that has been de-iced, and further improving the accuracy of subsequent detection results.

[0052] Embodiment three:

[0053] The technical solution is basically the same as that of the first embodiment, see Figure 1 and Figure 4 The difference is that a fault detection component 6 is arranged on the left side inside the detection box 1.

[0054] The fault detection component 6 includes a battery 61, which is fixedly installed in the middle of the upper end surface of the left side of the box body 11, and an image processor 64 is arranged above the battery 61. A detection frame 62 is symmetrically installed on the lower end surface of the left side of the box body 11, and a plurality of detection probes 63 are arranged on the detection frame 62. The detection probes 63 are connected to the battery 61 through wires, and the detection probes 63 and the image processor 64 are connected through electrical signals. The image processor 64 is connected to the terminal through electrical signals.

[0055] During specific operation, when the fault detection device of the power system is moved, the detection probe 63 can automatically and continuously take video of the line and transmit it to the terminal through the image processor 64. At this time, the terminal staff can determine whether this section of the line is faulty based on the video information.

[0056] In addition, the present invention also provides a method for using the above-mentioned fault detection device of the power system, comprising the following steps:

[0057] S1. First, knock off the ice crystals at the end of the line manually, and then pull the movable rod 34 to the front and rear sides respectively. At this time, the positioning spring 33 is compressed, and the movable wheel 35 will move away from the fixed wheel 37. Then, the fault detection device of the power system is manually installed on the line so that the line is located between the movable wheel 35 and the fixed wheel 37. Then, the movable rod 34 is released. At this time, the reaction force of the positioning spring 33 will drive the movable wheel 35 to move toward the fixed wheel 37, thereby tightening the line, starting the drive motor 21, and driving the drive shaft 22 to rotate through the drive motor 21, thereby driving the drive pulley 24 to rotate. Under the action of the annular belt 27, the driven pulley 26 and the transmission shaft 25 will also rotate synchronously. Under the action of the second bevel gear 38, the fixed rod 36 and the fixed wheel 37 will rotate, thereby driving the entire fault detection device to move along the line;

[0058] S2, during the process of the above step 1, the second bevel gear 38 will also drive the third bevel gear 41 to rotate during the rotation process, thereby driving the gear shaft 42, the knocking plate 43 and the rubber strip 44 to rotate. The rubber strip 44 will continuously knock the line during the rotation process, thereby preliminarily breaking the ice crystals that have been formed on the line, which is convenient for the subsequent deicing operation. Subsequently, the hollow frustum deicer 52 will shovel off the ice crystals that were preliminarily broken in the previous step during the movement process;

[0059] During the rotation process, the driving shaft 22 will also drive the cam 531 to rotate, thereby driving the T-shaped rod 532 to move downward, and the elastic airbag 542 will also be compressed, and the air inside the elastic airbag 542 will enter the arc-shaped air storage tank 544 through the air guide tube 543, and finally blow to the inside of the hollow truncated cone de-icer 52 through the air nozzle 545, so as to blow out the solid ice in the gap between the hollow truncated cone de-icer 52 and the line, and prevent the hollow truncated cone de-icer 52 from getting stuck. Due to the setting of the heater 541, the airflow blown out by the air nozzle 545 has a certain temperature, thereby further improving the efficiency of blowing out the solid ice;

[0060] When the T-shaped rod 532 moves downward, the coil spring 533 is compressed, and the sliding rod 534, the wiping liner 535 and the sponge block 536 are driven to move downward through the T-shaped rod 532. When the T-shaped rod 532 moves upward, the reaction force of the coil spring 533 drives the sliding rod 534, the wiping liner 535 and the sponge block 536 to move upward, and so on, so as to wipe the surface of the line that has been de-iced, and further improve the accuracy of the subsequent detection results;

[0061] S3. Finally, during the movement of the fault detection device of the power system, the detection probe 63 can automatically and continuously take video of the line and transmit it to the terminal through the image processor 64. At this time, the terminal staff can determine whether this section of the line is faulty based on the video information.
