Description
Technical field
The present invention relates to power external insulation technical field of coatings, a kind of anti-pollution flashover coating and preparation method thereof is particularly related to.
Background technique
Power industry is to be related to the great cause of national economy, and the safe and stable operation of electric system is happy and peace basic guarantor
Barrier.With the development of modern industry, environmental pollution is got worse, and various dirt contents gradually increase in atmosphere, and dust collects gradually
It ties in insulator surface, dust can be moistened under the adverse circumstances such as thick fog, rain, snow, frost, under keeping the insulating capacity of insulator significant
Drop, leakage current increases severely under the action of working voltage, so that arc discharge occurs, causes pollution flashover accident.
Currently, antifouling work most efficient method is to spray anti-pollution flashover coating on the insulator, wherein room temperature vulcanized silicone rubber
(RTV) silicon rubber used in anti-pollution flashover coating at room temperature can curing molding, easy to use, pollution flashover ability is strong, can extensively
Adapt to a variety of naturally filthy and industrial filthy environments.RTV is used as Anti-pollution Flashover measure, can exempt that timeliness is short, reliability
Low and heavy workload cleaning and washing work, so that saving largely maintenance manpowers and maintenance cost, effect is much better than adjustment
External insulation creep distance or other measures, and a large amount of equipment update cost can be saved, there is preferable economic benefit.
But RTV coating is coated to power equipment surface, and outdoors, RTV coating will be subjected to long-play in operational process
The effect of a variety of environmental factors such as temperature change, humidity change, ultraviolet light irradiates, wind and rain is scrubbed, ablation of discharging, acid and alkali corrosion,
Especially under special environment, such as low temperature severe cold area, it is high-strength inevitably to receive certain deterioration factor for serious haze area
Phenomena such as spending long duration of action, frequently can lead to the decline of coating hydrophobicity, hydrophobicity loss, cracking, galvanic corrosion damage, peeling, then
Cause pollution flashover accident in inclement weather.
In recent years, the quickening of process of industrialization results in frequently occurring for haze weather, and electric transmission line isolator is such
Easily there is a phenomenon where insulating capacities to reduce under weather condition, so that pollution flashover accident occur.These pollution flashover accidents are analyzed
After find, pollution flashover mostly occurs in morning in winter and mostly with intensity haze weather, and temperature is lower and the filthy concentration of environment is larger,
Environment filth concentration leads to greatly the accumulation of serious pollution layer, then will lead to silastic material hydrophobicity performance and declines, and low temperature environment
Make small molecule migration velocity relatively slow again or even migration completely does not come out, silastic material just loses antifouling work in this case
Key technology, easily generation pollution flashover, such as the North China of northeast in 2001 large area pollution flashover accident, the environmental characteristic of accident is: high
Humidity continues thick fog weather, and low visibility, temperature -3-7 degree, humidity 60%-90%, quality of air environment is poor, is electrolysed in air
Matter concentration is higher, occurs peak in the period of pollution flashover, and insulator salt density is high；In addition pollution flashover route entirely exists
Carried out cleaning respectively in November, 2000 and December, and many routes have been changed to silicon rubber compound insulator, this explanation is in short-term
In, because the influence of weather and environment still can make rapidly surface filth degree reach higher concentration.For such regional winter
Haze weather is presently the most the climate characteristic for being typically easy to cause pollution flashover, on the one hand due to being that contamination is cumulative between Winter-Spring
Phase, the wet deposition of the electrolyte in another aspect fog cause insulator surface to generate quickly pollution again, have deposited pollution and external
Pollution superposition, causes power transmission and transforming equipment that pollution flashover occurs under the humidification of lasting high humility dense fog.Therefore, how quickly to mention
The migration of hydrophobicity rate of high antifouling flash coating layer at low temperature is particularly important.
The external comparison carried out is early in terms of the exploitation of anti-pollution flashover coating, and the 1980s, the power grids such as U.S. started to develop
The anti-pollution flashover coating of organosilicon material, but state's rustproof lacquer lays particular emphasis on the hydrophobicity of material, other performances (such as mechanical property, fire-retardant
With resistance to deteriorating property) generally, do not adapt to domestic seriously polluted and complicated and changeable weather, the end of the eighties country inspired after
Start the room temperature vulcanized silicone rubber anti-pollution flashover coating of development multicomponent and one-component, and in some area applications and achieves
The problems such as effect, but generally existing poor mechanical property, adhesive force is low, and weatherability is poor and the migration of hydrophobicity service life is short.It is till now
Only, the research of the performance of coating various aspects was not also stopped, being received as Chinese patent literature CN1690147A discloses one kind
The reinforced RTV long-acting and anti-fouling flashing coating of rice, the coating by nano silica, terminal hydroxy group base dimethyl silicone polymer, crosslinking agent,
Catalyst, pigment and solvent are prepared, and have good hydrophobic performance and by addition nano material silica, enhancing
The mechanical property of coating, so that the weatherability of RTV coating enhances, antifouling work ability further strengthens.However the prior art
It is made that the migration performance of coating at low temperature is poor, is easy serious contamination under haze environment in winter and finally forfeiture insulation protection
Function.In addition, Chinese patent literature CN103131240A discloses a kind of automatically cleaning anti-pollution flashover coating, which constructs well
A kind of micro-nano composite surface of bionical class lotus leaf, so that self-cleaning effect is realized, however this automatically cleaning is in long-term outdoor
In operation, the environment extremely polluted as haze is encountered, when the filth on surface is taken away in no rainfall or strong wind, once table
Face accumulation is filthy, will cover surface class lotus leaf structure, so-called automatic cleaning action is also just difficult to play.If such feelings
In winter under haze, the filth on surface is easily soaked by wet air condition, greatly reduces the insulating capacity of equipment, is easy hair
Raw pollution flashover accident.And above two disclosed anti-pollution flashover coating technology all limits antifouling work ability and weatherability, Bu Nengman
The requirement that the increasingly severe complex environment demand of foot and growing transmission of electricity load height insulation ensure.
