Abstract
The invention discloses a porcelain insulating surface processing method for an electric transmission line. The porcelain insulating surface processing method for the electric transmission line comprises the following steps of: spraying one layer of polytetrafluoroethylene material on the porcelain surface of a porcelain insulator; solidifying the porcelain insulator at the high temperature of 200DEG C for 5 minutes; carrying out high-temperature solidification processing on polytetrafluoroethylene coating. According to the porcelain insulating surface processing method for the electric transmission line, which is disclosed by the invention, one layer of polytetrafluoroethylene material is evenly sprayed on the porcelain surface of the porcelain insulator, so that water or dirt is difficult to adhere onto the surface of the polytetrafluoroethylene material, and the problems of dirt accumulation and ice coating can be effectively solved; the insulator combined with the polytetrafluoroethylene has low surface energy, the dirt is difficult to adhere to the insulator, and the porcelain insulating surface hydrophobicity is improved; the breakdown voltage of the polytetrafluoroethylene material is extremely high, the insulation performance is excellent, and the service life of the polytetrafluoroethylene material is equivalent to that of the porcelain insulator. The processing method disclosed by the invention is simple, the power outage re-coating problem of the RTV (room temperature vulcanization) technology is avoided, the ice and dirt prevention performance of the power grid can be greatly improved, the maintenance cost is reduced, and the long-term safe operation of a power grid is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of transmission line maintenance in electric power systems, and in particular relates to a method for treating the porcelain insulation surface of a transmission line. Background technique [0002] At present, most transmission lines use porcelain insulators as the insulation medium, but porcelain insulators are prone to accumulate pollution, the pollution flashover voltage is very low, and they are easy to be covered with ice in rainy and snowy weather. The existing RTV (room temperature curing silicone rubber) technology can only solve the problem of pollution flashover , At the same time, the operating life of RTV is much lower than that of porcelain insulators, and it needs to be recoated regularly. [0003] There is currently no effective solution to the problems of fouling and icing. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a porcelain ...
