Description
Technical field
The invention belongs to electric power electric field of engineering technology, particularly a kind of novel solid insulation surface science and engineeringSkill.
Background technology
Insulating part kind in high-tension distribution equipment is numerous, and according to concrete function needs, the processing on insulating part surface alsoDifferent. In recent years, along with State Grid Corporation of China is more and more higher to the requirement of electrical equipment performance, to the environmental adaptation of productThe requirement of property and shelf depreciation is also more and more stricter, in insulating part surface spraying ground plane technology just in order to meet national gridThe new demand of company to electrical equipment and a kind of innovative technology of proposing, the consolidating for distribution engineering of especially current new releaseBody insulation ring main unit, domestic conventional technology is at present that insulating part outer surface is sprayed to ground plane completely, this technique can be fineGuarantee product be not subject to the impact of external environment condition, and can effectively eliminate the impact of surface induction voltage, solve product shelf depreciationProblem. The technique of this spraying ground plane implementation is traditionally: after solid insulation has been produced, use sandblastMachine destroys the sandblast artificial bright and clean outer surface of insulating part layer, then with alcohol, the dust on insulating part surface is totally clean,Then conduction or the semiconductive sprayed on material realized after allotment are coated on insulating part surface to warp by compressed air or brushVolatilization after a while and air-dry after, finally the insulating part that is coated with ground plane is put into and in baking oven, is carried out hot setting, straightTo surface earthing layer curing sticking on insulating part surface completely. Although above-mentioned this traditional spraying coating process can be realized in insulationThe designing requirement of ground plane is set up on part surface, but also has the following disadvantages:
1. because the bright and clean layer to insulating part surface carries out sandblast destruction, so the protection against the tide of insulating part, dustproof texts are tightHeavily decline;
2. by the mode of manually utilizing compressed air or brushing, conductive material is coated to insulating part surface, not only makes to connectThe uniformity on stratum and fineness can not get controlling, and ground plane material is through compressed-air actuated extruding, easily forms a large amount ofFinely ground particles be suspended in air, human body and environment are impacted;
3. because production complete after ability ground plane is coated to insulating part surface, with insulating part can not be one-body molded,Ground plane
Degree of adhesion undesirable, product surface is coarse, the protection against the tide of ground plane and dust-proof effect are not good, more seriously connectStratum is very easily subject to the destruction of external force, careless slightlyly just may make ground plane forfeiture effect.
In order to overcome the deficiency on above-mentioned insulating part process of surface treatment, a kind of novel solid insulation surface is proposedScience and engineering skill is very necessary.
Summary of the invention
The object of the invention is to the deficiency in order to overcome current insulating part process of surface treatment, a kind of technique letter is providedSingle, product is attractive in appearance but also performance is splendid, adaptive capacity to environment is strong solid insulation process of surface treatment not only.

C, solid insulation process segment: the inserts heating is in advance installed in mould and matched moulds, and inserts is enteredRow heats again, after mould and inserts temperature stabilization, enters the material feeding stage, and preprepared insulating materials is injected into mouldIn, carry out heat-insulation pressure keeping curing molding by the mould of elevated-temperature seal;
D, the solid insulation demoulding, cleaning: after products solidifying moulding, carry out product stripping, after taking-up product, product is enteredRow cleaning, removes the matched moulds limit of product, and some defects is repaired;
Cure stage after E, high temperature: the solid insulation of being made up of thermosets is carried out solidifying after high temperature, to solidInsulating part is completely curing;
F, inspection, warehouse-in: after solid insulation is naturally cooling, the parameters such as its dielectric strength, ground plane resistance are examinedSurvey, qualified product is put in storage; So far, complete the production of a solid insulation.
Further, in described step B, mold heated temperature is 120 DEG C-150 DEG C, time 0-3min.
Further, in described step B, conductive material is the conductive material of carbon containing bronze, and the proportioning of conductive material is semiconductorPaint: retarder thinner=1.5:1, the thickness of conductive material layer is 0.1-0.5mm; The coating thickness of bond layer is for being less than 0.1mm.
Further, in described step C, the heating-up temperature of inserts is 150 DEG C-180 DEG C; The curing time of heat-insulation pressure keeping is looked productProduct size and determining, be 30-120min hardening time.
Further, in described step e, after high temperature, solidification temperature is 110 DEG C-150 DEG C, and the time is 6-12h.
Further, described solid insulation is during without the need for conductive earthing layer, the spraying conductive material in cancellation step BWith two processes of spraying and adhesive bonding agent.
The present invention has the following advantages: the present invention adopts the technique of hot setting, by the specially treated to mould, coordinatesCorresponding production technology, can not only increase for solid insulation is surperficial the conductive earthing that one deck and insulating materials combine togetherLayer, the outward appearance that can also beautify insulating part; Technique of the present invention is simple, and prepared product good insulation preformance, dust and moisture effect are good,Reliable, can strengthen the creep distance of solid insulation, improve the environmental suitability of product.
