Background
Along with the continuous development of electric power systems in China, more and more attention is paid to the safe and stable operation of high-voltage transmission lines. Especially in high-voltage, ultrahigh-voltage and extra-high-voltage power transmission systems which are vigorously developed in recent years, whether the insulator can effectively and stably operate is an important index for determining the safe operation of the whole system. In order to ensure the safe operation of the high-voltage transmission line, the high-voltage transmission line needs to be detected after operating for a period of time, particularly the insulation capacity of an insulator, so as to prevent the occurrence of a short circuit phenomenon.
The toughened glass insulator has the advantages of small size, light weight, high strength, large creepage distance, zero value self-breaking and the like, and is widely applied to high-voltage transmission lines. The insulator in outdoor operation receives various natural environment's influence for a long time, and dirt must be piled up on its surface, and the comprehensive pollutants such as mainly have greasy dirt, salinity, carbon stain, acid-base gas, charged particle lead to its insulating resistance to descend, cause the pollution flashover accident easily, lead to transmission of electricity system trouble, consequently need regularly clean the insulator that receives dirt. At present, the traditional cleaning mode in China is that manual tower climbing cleaning or simple auxiliary cleaning machinery is arranged for cleaning, the labor intensity is high, the operation danger coefficient is high, and power failure operation is needed, so that huge economic loss is caused.
On the power transmission line, a plurality of groups of disc insulators are connected with each other to form a string structure, and the power transmission line is connected with a power transmission iron tower through the string structure. The existing auxiliary cleaning machine only comprises a cleaning mechanism, when the auxiliary cleaning machine is used, the auxiliary cleaning machine needs to be placed at an insulator through a rod or a tower, and the auxiliary cleaning machine needs to be manually moved to another insulator after one insulator is cleaned, so that the auxiliary cleaning machine is inconvenient to use.
Chinese invention patent CN109909208B (published as 2019, 10 and 29) discloses a live line insulator contamination self-cleaning device, which comprises a moving device, a driving device, a cleaning device, and an electrical device: the moving device comprises a plurality of groups of moving mechanisms, and each moving mechanism comprises a fixed plate, a first jaw, a second jaw, a synchronous belt, a synchronous wheel, a supporting rod, a supporting plate and an infrared sensor; the driving device comprises a first gear box, a second gear box, a linkage mechanism, a first driving motor, a second driving motor and a wire collecting box; the cleaning device comprises a mounting component and a cleaning component; the electric device comprises an electric box, wherein the electric box comprises a threading hole, a box door, a threading groove and a lead. The device is fixed on an insulator string through the first clamping jaw and the second clamping jaw, and walking on the insulator string is achieved. However, the insulator string is circular, and when the insulator string is used, two ends of the insulator string are respectively connected with the power transmission line and the power transmission tower, so that when the insulator string is used, the insulator string needs to be detached, and the insulator string is sleeved into the insulator string from one end of the insulator string, so that the use is inconvenient. In addition, the insulator string is hung on an insulator string by clamping the insulators, the insulators on the insulator string are connected together through a connecting hardware fitting, and a bearing cleaning device can influence the connection of the insulators and possibly cause the breakage of the insulator string; secondly, the thickness of some insulators is small, the insulators are cracked when the insulators are clamped to mount the cleaning device, and the diameter of some insulators is small, so that the insulators are difficult to clamp and difficult to stably mount; and finally, the surface of the insulator is coated with a layer of RTV hydrophobic material, and the insulator is used for fixing the cleaning device, so that the coating layer on the surface of the insulator is easy to damage, and the adverse effects of failure of the insulator, shortened service life and the like are caused.
