Abstract
The invention is a process for dip-painting a semi-enveloped 10KV-level high voltage coil and comprising the steps of: taking off the cover of a dip-painting tank, stably and vertically lifting the qualified coil into a lining tank, and putting on and fastening the cover; vacuumizing to 100 Pa below; transporting the dipping paint from a storage tank into the dip-painting tank; as vacuumizing to 600 Pa, closing the vacuumizing button; as pressurizing to 0.55 MPa, closing the pressurizing button; closing the vacuumizing button; as pressurizing to 0.55 MPa, closing the pressurizing button; closing the vacuumizing button; as pressurizing to 0.55 MPa, closing the pressurizing button; depressurizing to 0.2 MPa; opening and closing the paint transporting value; pushing the coil into an oven and waiting until curing. The advantages: it can fill solvent-free insulating dipping paint in the SCRB10 semi- enveloped high voltage coil, so as to achieve the effect of low local discharge, even no local discharge.
Description
Technical field
What the present invention relates to is a kind of solvent-free insulated impregnating varnish to be full of the half-packaging high-voltage coil internal voids, reduce coil inside office high-volume to reach, even reach no office and put the SGRB10 of requirement (a kind of national standard model of transformer) and partly seal the extraordinary paint-dipping process of 10KV level high-tension coil, belong to the high pressure multi-layer cylinder formula coil paint-dipping process technology neighborhood of transformer.
Background technology
At present, the high pressure disc coil of SG10 dry-type transformer all adopts vacuum pressure impregnation technology, and concrete processing step is specific as follows:
1, opens the dipping lacquer cover, qualified coil is steadily vertically hung in the lining jar.Cover and fastening dipping lacquer cover; 2, opening vacuum pump vacuumizes impregnating vessel; 3, close vacuum pump during for 600pa when vacuum degree, and kept this state about 30 minutes; 4, open defeated lacquer valve, the solvent-free paint in the storage paint can is transported in the impregnating vessel,, close defeated lacquer valve when the solvent-free paint height exceeds coil 50mm～100mm; 5, opening vacuum pump vacuumizes impregnating vessel; 6, close vacuum pump during for 600pa when vacuum degree, and kept this state 30 minutes; 7, impregnating vessel is pressurizeed (dry compressed air), when being forced into 0.5Mpa, close vacuum pump, and kept this state 30 minutes; 8, impregnating vessel is carried out the pressure release first time, when making the pressure of impregnating vessel reduce to 0.2Mpa, stop pressure release,, the solvent-free paint in the impregnating vessel is got back in the storage paint can by the pressure of 0.2Mpa; 9, in the lining jar of impregnating vessel coil is dripped lacquer, the time is 30 minutes; 10, impregnating vessel is carried out complete pressure release, open the dipping lacquer cover, will soak the pallet that good coil hung out and gently put into coil vertically, stably, wait for and solidifying.The high pressure disc coil of SGB10 dry-type transformer is a cake formula structure, and the sensible solvent-free insulated impregnating varnish of above process implementing is easy to infiltrate through coil inside, the coil inside space is filled up, thereby reduced partial discharge, even reach no office and put requirement.Yet because SGRB10 partly seals 10KV level high-tension coil structure is the multi-layer cylinder formula, the number of plies of coil is more, and use filling insulating material between layer and the layer, cause interlayer comparatively closely and with less air gap, if the paint-dipping process of SGRB10 half-packaging high-voltage coil is pressed the vacuum pressure impregnation technology of SGB10 dry-type transformer and is carried out, will cause solvent-free insulated impregnating varnish can not fill up the air gap of SGRB10 half-packaging high-voltage coil inside (by test, impregnating varnish fill up approximately coil 1/3), make the office of transformer put increase (be about national standard hundreds of times).
Summary of the invention
The objective of the invention is to defective at above-mentioned existence, propose a kind of SGRB10 and partly seal the extraordinary paint-dipping process of 10KV level high-tension coil, can make solvent-free insulated impregnating varnish be full of SGRB10 half-packaging high-voltage coil inside, put even do not have the effect that office puts to reach low innings.
Technical solution of the present invention: SGRB10 partly seals the extraordinary paint-dipping process of 10KV level high-tension coil, vacuum pouring technology and open type SG10 transformer vacuum pressure impregnation technology in conjunction with epoxy SC transformer coil, vacuumize and pressurized treatments by circulation, make solvent-free insulated impregnating varnish be full of SGRB10 and partly seal 10KV level high-tension coil, its processing step branch
