Abstract
Antifouling flashover coating applied to insulators is prepared by silica rubber and conducting filler silicon carbide with mass percentage of 15%-30%, wherein the molecular weight of the silica rubber is larger than or equal to 5000 and lower than or equal to 20000. The using method of the antifouling flashover coating is that: coating the coating on the lower surface of an insulating member of an insulator, wherein the thickness of the coating is within 0.3-0.4mm. The antifouling flashover coating applied to insulators maintains hydrophobicity, simultaneously can even distribution of the electric field of the insulator, fastens the surface drying process of the insulator under the wet and dirt conditions of the insulators, simultaneously evens the distribution of the electric field of the insulator when affected with damp and improves fouling voltages of insulator strings. Further, the antifouling flashover coating has the advantages of being simple in processing processes, few in using amount of single insulators and low in cost.
Description
Technical field
The present invention relates to a kind of coating, especially relate to a kind of lip-deep antifouling flush paint of electric transmission line isolator that is coated in.The invention still further relates to the method for use of said antifouling flush paint.
Background technology
Along with China's rapid development of economy, the scale and the capacity of electrical network are increasing, and extra-high voltage, ultra-high voltage large vol project of transmitting and converting electricity occur in succession, and be also increasingly high to the reliability requirement of operation of power networks.Pollution flashover accident is a great problem that present electric power netting safe running faces, and pollution flashover not only can cause the loss of a large amount of electric energy, the more important thing is to cause large-area power failure, causes serious social influence.Yet since transmitting line is born, just constantly be accompanied by the generation of pollution flashover accident.Therefore, electric power operation department is also in the anti-pollution flashover ability that constantly takes various measures to promote external insulation equipment.Along with being on the rise of topsoil, the pollution flashover problem of power transmission and transforming equipment is just causing increasing attention.
On transmitting line; Application of insulator is very extensive; The external belt electroconductive of the bus of overhead transmission line, power station and electric substation and various electricinstallations must be used the insulator support, and makes it and the earth (or ground connection thing) or other have the conductor insulation of potential difference.Mainly forming of general insulator by chapeau de fer, insulating part such as toughened glass or pottery etc. and steel pin, and clamp with cementing agent gummed or machinery and to form.
The coating on the insulating part surface of traditional insulator (directly address is insulator surface traditionally) is PRTV, RTV etc.; Apply the insulator of above-mentioned coating; In operational process, have good hydrophobic nature, can reduce the probability that the contaminated insulator pollution flashover takes place to a great extent.But there is data to show, in recent years also relevant for the accident of the insulator chain generation pollution flashover that has applied traditional antifouling flush paint.According to research, because the characteristic of above-mentioned coating itself, after being coated on the insulator chain surface, the deterioration situation appears in insulator chain surface field on the contrary, has reduced the pollution flashover voltage of insulator chain.Therefore, the distribution that new coating how just can also uniform insulation substring surface field when guaranteeing traditional antifouling flush paint hydrophobic nature, important just seems for insulator dirt-proof.
Summary of the invention
Technical problem to be solved by this invention; Just provide a kind of antifouling flush paint that is applied to insulator; After it is coated in insulator surface; Can make insulator under wet dirty condition, keep in the good hydrophobic nature can also the uniform insulation substring surface field distribute, thereby improve the pollution flashover voltage of insulator chain, help ensureing the safe operation of power system.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of antifouling flush paint that is applied to insulator is characterized in that: the component of described antifouling flush paint is: Zylox and massfraction are 15% ~ 30% conductive filler material silit.
Described Zylox molecular weight more than or equal to 5000, be less than or equal to 20000.
The described method of use that is applied to the antifouling flush paint of insulator: be coated on the insulating part lower surface of said insulator, coat-thickness is in the scope of 0.3 ~ 0.4mm.
The present invention has following beneficial effect: the base material of antifouling flush paint is a silastic material, and the coating after the curing has hydrophobic nature, and the hydrophobic angle is 100 ~ 120 °, in coating making processes, adds conductive filler material silit, can not damage the hydrophobic nature of coating; Said antifouling flush paint is coated on the lower surface of insulator dielectric spare, and when fine weather, the insulator surface leakage current maintains than fractional value, approaches 0; When insulator under wet dirty condition during charging operation; The leakage current values of insulator surface is about 1 ~ 20mA; The antifouling flash coating layer of insulator surface generates heat under the effect of leakage current, has improved the surface temperature of insulator, has accelerated the drying course of insulator surface; In addition,, thereby improve the pollution flashover voltage of insulator chain, help ensureing the safe operation of power system because the existence of conductive filler material in the coating can be played the effect that uniform insulation substring surface field distributes.
