Description
Technical field
The present invention relates to transformer production field more particularly to a kind of production methods of oil-immersed type transformer.
Background technique
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is coil and iron core.
Coil there are two or more than two windings, wherein connecing the winding of power supply primary coil, remaining winding is secondary coil.It
Alternating voltage, electric current and impedance can be converted.The iron core and cover that simplest iron-core transformer is made by a soft magnetic materials
Equal coil is not constituted two the number of turns on iron core.
Oil-immersed type transformer is that iron core winding is put into insulating oil, using oil as transformer primary insulation means, and is relied on
Oil makees cooling medium, such as oil, oil, oil immersed water cool and forced oil-circulation etc..The main component of transformer has iron
Core, winding, fuel tank etc..Oil-immersed type transformer silicon steel sheet interlayer, due to immersing transformer for a long time, oil can penetrate into wherein, and transformation
Device oil is flexible to be worked as a buffer, therefore oil-immersed type transformer noise is small；Since it is with lot of advantages, it is widely used.
The coil windings of existing oil-immersed type transformer are to be put into mailbox after winding, the resistance to deformation intensity of coil windings compared with
It is small, in turnover assembling and transport installation process, it is easy to happen phenomenon of colliding with, causes coils press deformation even damaged, causes
Coil windings short circuit or damage.
Summary of the invention
Present invention aim to address above-mentioned deficiencies, provide a kind of production method of oil-immersed type transformer.
A kind of production method of oil-immersed type transformer provided by the invention, it is characterised in that the following steps are included:

Step 2, the coil windings of the oil-immersed type transformer of one end mopping after drying are inverted, are applied in the other end of coil windings
The epoxy resin paint of brush allotment, end mopping dosage press end area 2.5-3 kilograms per square meter；End brushed after in coil
The epoxy resin paint of the outer wall brushing allotment of winding, outer wall mopping dosage press 0.5-0.8 kilograms every square of outer wall cylinder area
Rice, standing and drying 6 hours after having brushed；Subsequent processing assembling is carried out after drying.
Further, Epoxy Resin Oil enamel-cover described in step 1 and step 2 contains following parts by weight component: unsaturation tree
