In order to measure the water-intake rate of the dry-type power transformer high moisture wire enamel in the present invention in embodiment 1-embodiment 5, contriver first adopts identical preparation technology to produce dry-type power transformer high moisture enameled wire coat in embodiment 1-embodiment 5, take following way to measure the water-intake rate of corresponding enameled wire coat again, concrete way is as follows:
Step 1: dry-type power transformer high moisture enameled wire coat is placed in the baking oven of 200 degrees Celsius, dry 2 hours;
Step 2: again the dry-type power transformer high moisture enameled wire coat of step 1 is placed on constant temperature (25 degrees Celsius) water-bath and soaks 2 hours;
Step 3: the surface water mark of the dry-type power transformer high moisture enameled wire coat in step 2 is wiped, weighs;
Step 4: repeating step 1-step 3, amounts to 3 times, calculates the mean value of three times
After above-mentioned test way, contriver obtains as the data in table 1, simultaneously in order to the performance of dry-type power transformer high moisture wire enamel provided by the invention is described better, contriver has also measured the respective performances of polyesterimide wire enamel conventional in this area.
As shown in Table 1, the water-intake rate of the high moisture enameled wire coat water-intake rate far below polyesterimide wire enamel film conventional in this area of the dry-type power transformer in embodiment 1-embodiment 5.Dry-type power transformer in embodiment 3 with the water-intake rate of high moisture enameled wire coat also far below the water-intake rate of the high moisture of the dry-type power transformer in other embodiments enameled wire coat, reduce 57% than the water-intake rate of polyesterimide wire enamel film conventional in this area simultaneously, significantly increase humidity resistance, further increase enameled wire mechanics and electric property, finally improve the safety and reliability of the electric installations such as the transformer using dry-type power transformer high moisture wire enamel provided by the invention, tool has an unexpected effect.
Table 1
As shown in Table 1, in the present embodiment 3, provide dry-type power transformer high moisture wire enamel, comprise each component of following parts by weight: dimethyl terephthalate (DMT) 105 parts, mphenylenediamine 48 parts, trimellitic acid 1,2-anhydride 53 parts, ethylene glycol 19 parts, TDE 28 parts, mica powder 14 parts, phenol 38 parts, glycerine 76 parts, linking agent 12 parts, flow agent 4.5 parts, solvent 18 parts.Wherein, linking agent is that TriMethylolPropane(TMP), m-xylene diamine and tetra-n-butyl titanate mix by weight for 1.5:1:2.5, flow agent is that acrylic resin and polydimethylsiloxane mix by weight for 1:1, solvent benzol ethene, trieline and ethylene glycol ether are by weight when mixing for 1:2:1, its water-intake rate is far below polyesterimide wire enamel conventional in other embodiments and this area, contriver thinks the compositional selecting in this and the present embodiment, comprise bed material, linking agent, flow agent, the selection of solvent all has singularity.
Contriver thinks, owing to having ehter bond and sec.-propyl in the molecular structure, add macromole chain flexibility and free body, linking agent adopts TriMethylolPropane(TMP), m-xylene diamine and tetra-n-butyl titanate to mix by weight for 1.5:1:2.5 simultaneously, greatly strengthen intermolecular crosslinked action, and there is crosslinked action when solidifying in hydrophilic radical, make the surface energy of surface energy far below water of dry-type power transformer high moisture enameled wire coat, thus there is good hydrophobicity and moistureproofness.Contriver also finds simultaneously, if only adopt combination that is a kind of in TriMethylolPropane(TMP), m-xylene diamine, N hydroxymethyl acrylamide, tetra-n-butyl titanate or other ratios, all cannot realize the special performance boost of the present embodiment, visible only under this specific components mode and part by weight relation, dry-type power transformer high moisture wire enamel provided by the invention can produce beyond thought synergy, realizes beyond thought effect.
Flow agent is that acrylic resin and polydimethylsiloxane mix by weight for 1:1, solvent benzol ethene, trieline and ethylene glycol ether are by weight when mixing for 1:2:1, coordinate together with other raw materials with linking agent, finally prepare the dry-type power transformer high moisture wire enamel that hydrophobic performance is splendid.
Simultaneously, the present inventor finds that again dry-type power transformer high moisture wire enamel provided by the invention is under the preparation of same composition differing temps, a certain distance is there is in the dry-type power transformer high moisture wire enamel produced in hydrophobicity and moistureproofness, enameled wire coat water-intake rate as embodiment 3 is 0.72%, is starkly lower than enameled wire coat in the enforcement 2 under the preparation of same component differing temps.Analyze its reason, the present inventor thinks to only have just can make the keying action of hydrophilic radical reach best within specified temperatures, thus makes dry-type power transformer high moisture wire enamel have significant hydrophobicity and moistureproofness.
Visible, in the present invention, the selection of component and content is all non-obvious, the selection of these components and content just, to act synergistically mutually, again in conjunction with specific working method, form a complete technical system, the dry-type power transformer high moisture wire enamel prepared finally just can be made to have excellent performance, meet the demand of practice; Therefore, technical scheme of the present invention is non-obvious.
Meanwhile, those skilled in the art know, and in the present invention, linking agent is TriMethylolPropane(TMP), m-xylene diamine, N hydroxymethyl acrylamide, tetra-n-butyl titanate; But in prior art, remaining linking agent can also be suitable for the solution of the present invention, within protection scope of the present invention.
Meanwhile, those skilled in the art know, and in the present invention, flow agent is acrylic resin, polydimethylsiloxane and PSI; But in prior art, remaining flow agent can also be suitable for the solution of the present invention, within protection scope of the present invention.
Meanwhile, those skilled in the art know, and in the present invention, solvent is vinylbenzene, trieline, ethylene glycol ether; But in prior art, remaining solvent can also be suitable for the solution of the present invention, within protection scope of the present invention.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
