9) drying at room temperature：Transformer is placed into the static air dry operation that 30-50min is carried out in room temperature environment；
10) secondary japanning drying：Individually repeat step 6) once, application process terminates.
Wherein, the gap in the step 2) includes the gap at screw interface, the gap at transformer case docking.
Wherein, the temperature of compacting tool set inner cavity is 15 DEG C -30 DEG C after preheating in the step 3).
Further, the shape of the inner cavity of the compacting tool set and the shape of transformer are corresponding.
Wherein, the grinding device in the step 4) is that steel is frustrated.
Wherein, the grinding depth in the step 4) is 0.05 ㎜ -0.1 ㎜.
Wherein, the transformer shell in the step 6) includes six faces, and six faces carry out japanning drying one by one.
Further, the thickness painted when transformer shell painting on surface in the step 6) is 0.15-1.5 ㎜.
Further, the surface of transformer needs the state being in horizontal direction when japanning is dried.
Wherein, the drying temperature in the step 6) when drying is 90 DEG C -95 DEG C, drying time period 2.5-3h.
Wherein, the formula of the paint used when transformer shell painting on surface in the step 6) includes following components：Epoxy
It is resin, rosin resin, polytetrafluoroethylene (PTFE), poly (propylene carbonate), polyvinyl butyral, aluminum nitride powder, asbestos, nano oxidized
Zirconium, cement, fire-proof additive, zeolite powder and Mineral spirits.
Further, the parts by weight of each component are in the formula of the paint：Epoxy resin 50-60, rosin resin 25-45,
Polytetrafluoroethylene (PTFE) 18-25, poly (propylene carbonate) 12-15, polyvinyl butyral 8-10, aluminum nitride powder 10-12, asbestos 8-12,
Nano zircite 6-8, cement 12-15, fire-proof additive 10-15, zeolite powder 8-12, dormant oil 12-18.
Further, the fire-proof additive includes noninflammability film forming matter, sodium chloride, ammonium phosphate, ammonium borate and stone
Ying Fen.
Further, the parts by weight of each component are noninflammability film forming matter 35-45, sodium chloride in the fire-proof additive
30-40, ammonium phosphate 20-30, ammonium borate 20-30, silica flour 28-34.
Compared with prior art, the beneficial effects of the invention are as follows：The step of transformer application process, is reasonable, and function is real
With the transformer smeared using the transformer application process is with good anti-corrosion and waterproof, sun-proof, cold-resistant and fireproof
Performance moreover can effectively ensure the service life of transformer, while can effectively obstruct some transformers
The noise generated when work.
Specific implementation mode
With reference to embodiments, invention is further elaborated.It should be appreciated that specific implementation described herein
Example only to explain invention, is not used to limit invention.
A kind of transformer application process, including steps are as follows：
1) transformer is assembled；
2) it fills：Filling with sealant in gap on transformer shell, gap include gap at screw interface, transformation
Gap at device shell docking can effectively avoid the gap at screw interface and the gap at transformer case docking from entering
Steam to make moist in transformer, also can effectively avoid screw and be led because generation redox reaction of making moist for a long time is got rusty
The service life of screw is caused to be affected；
3) it suppresses：Compacting tool set is preheated, after the completion of preheating using compacting tool set to the surface of transformer shell into
Row compacting, cooling and demolding is carried out after the completion of compacting to transformer, and the fluid sealant generated when filling can be effectively avoided after compacting
Irregular phenomenon is filled, fluid sealant quilt is avoided；
4) it polishes：It is polished on the transformer shell surface suppressed using grinding device, enhances transformer shell body surface
The degree of roughness in face, the contact area of paint and transformer shell surface when expanding japanning；
5) it clears up：Transformer shell surface is cleared up using dust exhaust apparatus, obtains the clean transformer of surface of shell,
It avoids the dust on transformer shell surface from being mixed into paint, influences the bonding strength between paint and transformer shell surface, ensure to become
The service life of depressor surface of shell paint；
6) japanning is dried：It is dried after transformer shell painting on surface, japanning；
7) secondary polishing：Slight polishing is carried out to transformer shell surface using sand paper, the depth of polishing is 0.02-
0.04 ㎜, avoid polishing excessively cause step 6) on paint beaten；
8) drying is cleaned：Transformer shell surface is cleaned using wet cloth, is placed into transformer after scrubbing
1.5-2h is dried in 45-50 DEG C of environment；
9) drying at room temperature：Transformer is placed into the static air dry operation for carrying out 30-50min in room temperature environment, avoids becoming
The phenomenon that getting damp is generated when depressor surface of shell is returned in room temperature environment, influences the japanning effect of step 10)；
10) secondary japanning drying：Individually repeat step 6) once, application process terminates.
Wherein, the temperature of compacting tool set inner cavity is 15 DEG C -30 DEG C after preheating in the step 3), by preheating so that compacting
Mold can make the sealing gum softening of the filling on transformer shell surface when being suppressed, and be convenient for compression moulding.
As a preference of the present invention, the shape of the inner cavity of the compacting tool set is corresponding with the shape of transformer.
Wherein, the grinding device in the step 4) is that steel is frustrated, and gently frustrates and transformer shell surface may make to become coarse,
And the state that can be preferably applicable in transformer shell surface irregularity is frustrated using steel.
Wherein, the grinding depth in the step 4) is 0.05 ㎜ -0.1 ㎜, can be become ensureing transformer shell surface
The phenomenon for effectively avoiding transformer shell caused by excessively polishing impaired while coarse.
Wherein, the transformer shell in the step 6) includes six faces, and six faces carry out japanning drying, and japanning one by one
The surface of transformer needs the state being in horizontal direction when drying, can effectively avoid at transformer painting on surface rear surface
In plumbness, paint is slid downwards by the weight effect of its own, leads to the non-uniform phenomenon of transformer painting on surface.
As a preference of the present invention, the thickness painted when transformer shell painting on surface in the step 6) is 0.5-1.5 ㎜,
