Abstract
The invention relates to a coil water-proof treatment process for a transformer for a railway vehicle. The process comprises the following steps of: first, coating a plurality of insulating materials outside a coil; then, dipping the coil which is coated with the insulating materials in paint; then putting the coil which is dipped in the paint into a baking box and performing drying and curing treatment; and finally, keeping the coil rotating when the coil is subjected to the curing treatment in the baking box, wherein the rotating axis is parallel to the horizontal plane. In the coil water-proof treatment process for the transformer for the railway vehicle, the coil is kept rotating when dried in the baking box, and the rotating axis is parallel to the horizontal plane, so that the paint attached to the coil can be uniformly cured on the surface of the coil; therefore, the water-proof performance of the coil is ensured.
Description
?
Technical field
the present invention relates to a kind of coil water-proof treatment technology of used for rail vehicle power transformation device.
?
Background technology
transformer coil mainly comprises conductor and insulating material two parts.Conductor plays transmission current, and insulating material is each circle mutually insulated of conductor, separates conductor and other component insulations of transformer inside simultaneously, and in the used for rail vehicle transformer, insulating material also possesses the shell protection function, like waterproof etc.
tradition dipping dry-type transformer coil will adopt dipping lacquer to handle, and insulating varnish will be cured after the dipping lacquer.Conventional curing process is to put into the direct baking and curing of baking oven after coil takes out from insulating varnish; Coil static placement in baking oven during curing; Since insulating varnish when just having begun to heat viscosity diminish and run off easily; Therefore the coil top insulating varnish after conventional curing process solidifies partly runs off, can not the complete filling insulating material, and the coil behind the dipping lacquer does not possess water-proof function.Therefore water resistance is relatively poor, can not work in moist environment, especially when it moves, if there is water droplet directly to spill when splashing on the transformer coil, possibly cause the damage of transformer even more serious consequence.
?
Summary of the invention
the object of the invention provides the coil water-proof treatment technology of the good used for rail vehicle power transformation of a kind of waterproof effect device.
In order to achieve the above object, the technical scheme that the present invention adopted is: a kind of coil water-proof treatment technology of used for rail vehicle power transformation device, and it may further comprise the steps:
A, at coil outerwrap multi-layer insulation;
B, the coil that is enclosed with insulating material is carried out dipping lacquer handle;
C, the coil after dipping lacquer handled are put into baking oven and are carried out baking and curing and handle;
described stating when coil is cured processing in baking oven keeps rotation and rotating shaft and horizontal plane to parallel.
described insulating material is processed by porous fibre.
described dipping lacquer is treated to vacuum pressure impregnation.
described dipping lacquer is handled with cured step in the vacuum paint dipping dryer and is accomplished.
are owing to adopt technique scheme; The present invention has the following advantages: in drying in oven, keep rotation at the coil described in the coil water-proof treatment technology of this used for rail vehicle power transformation device; And rotating shaft parallel is in horizontal plane; So can evenly be solidificated in coil surface, guarantee the water resistance of coil attached to the lacquer on the coil.
?
Embodiment
describe in the face of the preferred specific embodiment of the present invention down.
The coil water-proof treatment technology of this used for rail vehicle power transformation device may further comprise the steps: at first at coil outerwrap multi-layer insulation; Then the coil that is enclosed with insulating material being carried out dipping lacquer handles; Coil after at last dipping lacquer being handled is put into baking oven and is carried out the baking and curing processing;
described stating when coil is cured processing in baking oven keeps rotation and rotating shaft and horizontal plane to parallel.
In the present embodiment, described insulating material is processed by porous fibre
; Described dipping lacquer is treated to vacuum pressure impregnation; Described dipping lacquer is handled with cured step in the vacuum paint dipping dryer and is accomplished.
the foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this; Can not limit protection scope of the present invention with this, all equivalences that spirit is done according to the present invention change or modification all should be encompassed within protection scope of the present invention.
