Description
Technical Field
The invention relates to the technical field of pollution flashover prevention and control of transformer substations, in particular to a moss-preventing pollution flashover-preventing coating for a transformer substation insulator.
Background
Along with the increasing atmospheric environment pollution, the pollution flashover accident is more and more likely to happen to the power grid equipment under the influence of the pollution flashover accident, so that large-area power failure is caused, and the safe and stable operation of the power grid is influenced. The main factor causing pollution flashover of power grid equipment is that the surface of the insulator is polluted, such as smoke dust, sand particles, salt particles, seawater, rainwater and the like, a large area of moss grows in a humid place, and the pollutants can adsorb moisture and inorganic salt in the air under the humid air, so that a conductive layer is formed on the surface of the insulator, and flashover is easy to occur under the action of an electric field.
The ceramic insulator in the transformer substation in a humid place is easy to grow the moss which is a low-grade plant formed by symbiosis of chlorella and some fungi and has strong adaptability to the environment. Under the conditions of warm and moist and insufficient illumination, the propagation on the surface of the power transmission and transformation equipment is easy to occur in large quantities. The moss has little influence on the electrical performance of equipment, and mainly absorbs moisture inorganic salt in air to form a conductive layer on the surface of the insulator, so that pollution flashover is very easy to occur under the action of an electric field, thereby causing power failure accidents and influencing the safe operation of a power grid. At present, no better method is available for inhibiting the growth of moss on the insulator, and the moss can only be manually removed when the equipment is overhauled due to power failure, which is labor-consuming and low in efficiency. The problem can be effectively solved by the moss adhesion preventing coating for the insulator of the transformer substation, the coating is sprayed on the surface of the insulator, the antifouling flashover performance is good, metal ions such as Zn2+, Cu2+ and the like with a sterilization effect can be slowly released by an inorganic mildew-proof antibacterial agent contained in the coating in a humid environment, the effectiveness is more than 5 years, moss adhesion and growth on the surface of the coating can be finally inhibited, the occurrence of a pollution flashover accident is avoided, the moss adhesion preventing coating has great popularization value, and the moss adhesion preventing coating has important significance for building a strong intelligent power grid.
At present, the most effective method for preventing pollution flashover is to spray an antifouling coating with hydrophobic property on an insulator, in the prior art, the antifouling coating has a certain antifouling flashover effect in a dry environment, but for a transformer substation paved in a humid environment and a region, a large amount of moss is very easy to grow on the surface of the insulator due to the humid air, and the moss can adsorb moisture and inorganic salt in the air under the humid air, so that a conductive layer is formed on the surface of the insulator, and flashover is very easy to occur under the action of an electric field. Therefore, the antifouling flashover paint is also easy to have a flashover accident because the antifouling paint does not have the function of preventing moss in a humid environment. Therefore, there is a strong need for a coating having both anti-smudge and anti-moss properties. In the case of insulators, the formation of moss is caused by the contact of microorganisms in a humid environment with the outer surface of the insulator, so that the outer surface of the insulating material must contain a greater concentration of the moss-preventing component to achieve the moss-preventing effect. According to the prior art, the anti-pollution flashover material is generally coated outside the insulator, and then the anti-moss material is coated, however, the method needs to coat the surface of the insulator twice, the construction process is complex, and the method is particularly not favorable for large-area spraying construction on site.

the base material is room temperature vulcanized silicone rubber, and consists of 70 percent of basic silicone resin, 0.3 percent of cross-linking agent and 0.5 percent of catalyst in percentage by weight;
the auxiliary materials comprise 5 percent of reinforcing agent, 2.5 percent of mildew-proof antibacterial agent, 5 percent to 10 percent of pigment and 11.7 percent to 16.7 percent of solvent by weight percentage.
Further, the base silicone resin is composed of 60% by weight of vinyl polydimethyl silane silicon and 10% by weight of hydroxy silicone oil.

Further, the cross-linking agent component is dibutyltin dilaurate.
Further, the catalyst component is chloroplatinic acid.
Selection of the base material of the invention:
on the basis of a large number of experiments and data consultation in the previous period, the moss-preventing anti-pollution flashover coating adopts room temperature vulcanized silicone rubber which has high electrical insulation performance and can be cured at normal temperature as a base material. By researching and selecting vinyl polydimethylsilane silicon and hydroxyl silicone oil as basic silicone resin and dibutyltin dilaurate as a matched cross-linking agent and chloroplatinic acid catalyst, the raw rubber with good insulativity, short curing time and high curing degree is prepared.
The selection of the auxiliary materials of the invention:
the raw rubber has poor mechanical strength and thermal conductivity, and must be modified by adopting a filler. White carbon black and barium titanate prepared by a gas phase screening method and a precipitation method are used as proper reinforcing fillers, and heat-conducting fillers such as nano aluminum oxide and silicon nitride, temperature-resistant fillers and the like are selected to modify the prepared raw rubber so as to improve the mechanical property and the heat-conducting property of the raw rubber.
By adding inorganic anti-mildew antibacterial agents such as inorganic molecular sieve loaded copper oxide and zinc oxide particles, the moss-preventing anti-pollution flashover coating has the functions of preventing mildew and resisting moss growth. Compared with organic mildew-proof antibacterial agents, the inorganic mildew-proof antibacterial agents have the advantages of long lasting effect, difficult failure and the like.
By adding pigments with different colors such as iron red, phthalocyanine blue, chrome yellow and the like, the moss-preventing anti-pollution flashover coating has three colors of red, yellow and green, and can realize phase color representation. And the stability and the environmental protection property of the coating are ensured by selecting a proper diluent.
The above description is for the purpose of illustrating embodiments of the invention and is not intended to limit the invention, and it will be apparent to those skilled in the art that any modification, equivalent replacement, or improvement made without departing from the spirit and principle of the invention shall fall within the protection scope of the invention.
