Abstract
The present invention relates to a method for improving the antifouling property of an insulator. A layer of thin and uniform treating agent is coated on the surface of an insulator of cleaning tempered glass (or porcelain), the surface of the insulator is treated by any one of electric discharge, infrared irradiation, the combined irradiation of infrared and ultraviolet and the treatment of a high-temperature oven, and finally, the treated agent attached to the surface of the insulator is cleared. A layer of ultrathin generation film with strong hydrophobicity is formed on the surface of the insulator; the generation film improves the flashover voltage of the cleaning fog of power frequency and the fouling flashover voltage of the treated insulator in vast scale without aged deterioration in the process of the operation of a power system.
Description
The invention belongs to the processing method that improves porcelain insulator and toughened glass insulator anti-pollution characteristic.
The pollution flashover of insulator usually causes long-time, large-area power outage.In order to improve the power supply reliability of electric power system, conventionally adopt regularly cleaning (cleaning), reinforced insulation and use the measures such as Hydrophobic Coatings to be used as antifouling countermeasure.Its shortcoming is, some measure workloads and labour intensity are large, and what have is economical not, and adopting Hydrophobic Coatings is mainly easy aged deterioration, effective life not to grow (3～12 months), thereby the application of above-mentioned measure is all subject to certain limitation.For this reason, all seeking simple, the significant anti-fouling method of effect both at home and abroad for a long time.From patent, the document consulted, be mostly research Living water washing, development anti-pollution type insulator (comprising semi-conducting glaze insulator) and improvement coating composition are to extend the useful life of coating.Wherein only Japan Patent JA46-10253 (1973) is in the manufacture process of glass insulator, after employing is heated under the high temperature of not melting modification degree, in the time that blowing, also blows all surfaces of glass insulator mist, in the time being cooled to 200～300 ℃, dimethylchlorosilane vapor action, in all surfaces of glass insulator, is combined into the processing method of a procedure as feature using the processing of chilling tempering and water-proofing treatment.Its shortcoming is to be only confined to manufactory glass insulator is heat-treated, and operation department can not adopt; Blow and spray dimethylchlorosilane complex process, cause inorganic agent waste; Owing to not removing inorganic agent after surface treatment, not only make insulator be in operation easy aged deterioration, crust, affect useful life, also make insulator surface stick-slip, inconvenient dismounting.
For above-mentioned shortcoming, the present invention proposes a kind of simple, processing method that insulator anti-pollution characteristic is greatly improved.
Foundation of the present invention is, supply with that certain activation energy can make siloxane bond fracture and with glassy state (the glaze layer on porcelain surface also belongs to glassy state) surface chemical reaction or chemisorbed, form the principle of hydrophobic film.Main points of the present invention are to apply at clean toughened glass (or porcelain) insulator surface the dimethicone solution-treated agent that contains 5～10% ethanol or carbon tetrachloride, then from electric discharge, infrared radiation, infrared and ultraviolet joint irradiates, high temperature oven is processed in these four kinds of techniques and chosen any one kind of them insulator is carried out to surface treatment, finally remove inorganic agent, obtain one deck produced film as thin as a wafer, that hydrophobicity is very strong at insulator surface.This produced film is through solubility, destructive chemical test, and the rapid artificial aging and natural ageing test of nearly 3 years, proves that its performance is not completely deteriorated.
It is as follows that the present invention completes the processing step of insulator surface processing method:
I, to there is no the insulator of greasy dirt, attachment is removed and is rinsed well with running water afterwards, wipe (or blow, dry) water mark; To having the insulator of greasy dirt, first removing greasy dirt with the organic solvent such as gasoline, toluene, rinse well with running water again, wipe water mark, then spray one deck at toughened glass (or porcelain) insulator surface thin and contain uniformly the dimethicone solution-treated agent of 5～10% ethanol or carbon tetrachloride; If not production in enormous quantities, the dimethicone solution-treated agent that usable oils painting brush contains 5～10% ethanol or carbon tetrachloride in insulator surface brushing.For example, in the inorganic agent of use, can contain 5% ethanol or carbon tetrachloride.The insulator that applied inorganic agent is suspended on and is processed on frame, then from four treatment process below optional one insulator is carried out to surface treatment.
A, discharge process.The upper and lower surface uniform of insulator spray water smoke from the beginning, carry out power-frequency discharge 5～30 times simultaneously, discharge voltage boosts to discharge voltage equably by zero.For example, the number of times of power-frequency discharge can be 10 times.
B, infrared radiation processing.Temperature in infrared case is raised to 158～300 ℃ gradually, keeps 0.5～1 hour, then naturally cool to room temperature.For example, can be warmed up to gradually 170 ℃, keep 1 hour or be warmed up to gradually 200 ℃, keep 0.5 hour.
C, infrared and ultraviolet joint treatment with irradiation.Than being in 1/20～1/10 treatment box, allow temperature be raised to gradually 170～300 ℃ in the wattage of uviol lamp and infrared lamp, keep 0.5～1 hour, then naturally cool to room temperature.For example, can adopt uviol lamp and the wattage ratio of infrared lamp is 1/10, is warmed up to gradually 170 ℃, keeps 1 hour.
D, high temperature oven processing.Temperature in high temperature oven is raised to 160～300 ℃ gradually, keeps 0.5～1.5 hour, then naturally cool to room temperature.For example, can be warmed up to gradually 170 ℃, keep 1 hour.
Treat that insulator surface handles, with sodium hydroxide solution or ethanol, the inorganic agent of its surface attachment is washed away.
II, spraying water smoke from the beginning to insulator surface, is qualified if the discrete globule appears in insulator surface, otherwise the overall process of iterative process step I, until qualified.Finally the insulator clean mist of power frequency of sampling is dodged to test, in the time that the clean fog lightning pressure of power frequency approaches work frequency dry flash voltage, show all to process and meet the requirements.
The present invention to the environmental condition such as air pressure, temperature without specific (special) requirements, implementing process step I and II under general work condition.
Although the insulator through processing of the present invention is identical with untreated insulator appearance, but not stick-slip of insulator surface after treatment, be convenient to dismounting, be in operation and be difficult for aged deterioration, in its mechanical performance and power frequency are dry, voltage is close with the insulator when untreated, and the clean fog lightning pressure of power frequency improves 45～69% than untreated insulator, power frequency pollution flashover voltage is than improving 50～100%.
The present invention is applicable to the surface treatment of toughened glass (or porcelain) insulator to various electric pressures.Due to treatment process variation of the present invention, and all simple, with low cost, be not only suitable for manufactory and produce in enormous quantities, be also convenient to move department's small lot and improve electrical insulation properties.If the present invention is for the manufacture of factory, discharge process can be carried out in conjunction with delivery test, is to kill two birds with one stone.If operation department adopts the present invention, can select electric discharge, infrared radiation, infrared and ultraviolet joint irradiates and high temperature oven treatment process in any one, utilize existing testing transformer or assembling treatment box by oneself.
