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
The invention belongs to the Maintenance of Electric Transmission Line technical field of electric power system, relate in particular to a kind of porcelain insulating surface treatment method of transmission line.
Background technology
The more employing porcelain insulator of current power transmission circuit is as dielectric, but porcelain insulator easily accumulates filth, pollution flashover voltage is very low, at the easy icing of sleety weather, existing RTV(room curing silicon rubber) technology can only solve the pollution flashover problem, the service life of RTV will, far below the useful life of porcelain insulator, need regular overcoating simultaneously.
Contamination and icing problem also do not have effective solution at present.
Summary of the invention
The purpose of the embodiment of the present invention is to provide a kind of porcelain insulating surface treatment method of transmission line, and being intended to solve the contamination and the icing problem that have transmission line now does not also have the problem of effective solution at present.
The embodiment of the present invention is achieved in that a kind of porcelain insulating surface treatment method of transmission line, and the porcelain insulating surface treatment method of this transmission line comprises the following steps:
Step 1, at porcelain insulator porcelain piece surface spraying one deck polytetrafluoroethylmaterial material;
Step 2, by porcelain insulator 200 degrees centigrade of lower hot settings 5 minutes;
Step 3, process the teflon coating hot setting.
Further, in step 1, polytetrafluoroethylene is to have used fluorine to replace the artificial synthesized polymer material of all hydrogen atoms in polyethylene, and molecular structure is as follows:
Further, in step 3, the thickness of the teflon coating after solidifying is greater than 0.1mm.
The porcelain insulating surface treatment method of transmission line provided by the invention, by the spraying one deck polytetrafluoroethylmaterial material at porcelain insulator porcelain piece surface uniform, water or the filthy surface that is difficult to be attached to polytetrafluoroethylmaterial material, solved contamination and icing problem effectively; Because the insulator surface in conjunction with polytetrafluoroethylene can be very low, filth can't be adhered to, and has improved the hydrophobicity on porcelain insulating surface; The puncture voltage of polytetrafluoroethylmaterial material is high, excellent insulation performance, and useful life and porcelain insulator are suitable.Processing method of the present invention is simple, has avoided the power failure overcoating problem of the RTV technology of current employing, has greatly improved that electrical network is anti-icing, antifouling property, has reduced maintenance cost, has guaranteed the long-term safety operation of electrical network.
The accompanying drawing explanation
Fig. 1 is the flow chart of the porcelain insulating surface treatment method of the transmission line that provides of the embodiment of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
As shown in Figure 1, the porcelain insulating surface treatment method of the transmission line of the embodiment of the present invention comprises the following steps:
S101: at spraying one deck polytetrafluoroethylmaterial material of porcelain insulator porcelain piece surface uniform;
Spraying equipment mainly comprises appendix three parts of spray gun, air compressor and connection air compressor and spray gun, and the joint assembling between three parts should be solid and reliable, guarantees air pressure.Air compressor pressure is controlled at 0.8 ± 0.1Mpa, starts air compressor and can be sprayed after pressure stability.The spray-hole of spray gun, spray gun cavity and material-storage jar should clean free from admixture.Insulator surface 300 ± 50mm that the nozzle distance of spray gun is sprayed, the spray gun translational speed should be slowly even, the air-flow axial line with should be kept substantially vertical by sprayed surface.
S102: by porcelain insulator 200 degrees centigrade of lower hot settings 5 minutes;
S103: the porcelain insulator surface after hot setting should be smooth, smooth, do not lack spot, and the thickness of the teflon coating after solidifying is not less than 0.1mm and gets final product;
Teflon coating can just can be bonded to insulator surface through simple process in the insulator production process.
Increase the spraying process of a step teflon coating in the production line of insulator: after the insulator porcelain piece is manufactured, before steel cap and iron pin are installed, by the whole surface spraying teflon coating of insulator porcelain piece, then pass through high-temperature cabinet 200 degrees centigrade of lower hot settings 5 minutes; After solidifying, insulator porcelain piece surface has just formed polytetrafluorethylecoatings coatings.Again this porcelain piece is carried out to the conventional operation that next step installs steel cap and iron pin.The tissue order that the adding of spraying process can not affect other operation, and spraying and curing time very short, can not produce considerable influence to the production cycle of insulator.
Processing method of the present invention is simple, has avoided the power failure overcoating problem of the RTV technology of current employing, has greatly improved that electrical network is anti-icing, antifouling property, has reduced maintenance cost, has guaranteed the long-term safety operation of electrical network.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
