Description
Technical field:
The present invention relates to a kind of VPI stator bar.
Background technology
The manufacturing process of existing a kind of stator bar of turbo generator, it is 1) after wire is hot-forming, the mind-set two ends pare off insulating barrier from the conductor leptoprosopy, expose naked copper, stator bar is comprised of top bar and lower bar, top bar A repaiies one and reveals the copper point to the B point 88mm of being separated by, and top bar C repaiies a dew copper point to the D point 176mm of being separated by; Lower bar E repaiies one and reveals the copper point to the F point 102.7mm of being separated by, and lower bar G repaiies one and reveals the copper point to the H 205.4mm of being separated by, and equipotential layer length is 9210mm, even brushing one deck conductive paint in this scope, and then and around one deck low-resistance corona-prevention belt, the equipotential layer is namely finished; 2) the conductive line surfaces half-lap paulownia horse epoxy glass mica paper tape layer after process through equipotential layer on the edge is as main insulating layer; 3) after online excellent wire has held main insulating layer, determine to hinder anticorona coating in straight line low-resistance corona-prevention layer and the end, high resistant anticorona coating positions at different levels and line hold anticorona layer; 4) at straight line low-resistance corona-prevention layer place half-lap one deck low-resistance corona-prevention belt, line rod low-resistance corona-prevention layer end arrives distance A=350mm unshakable in one's determination vertically; Then resistance corona-prevention belt in the level half-lap hinders the anticorona coating wrapping and is of a size of 50mm in the excellent surface along the line; The wrapping of resistance anticorona coating is of a size of 120mm in the high resistance corona-prevention belt excellent surface along the line; The excellent surperficial high resistant anticorona coating wrapping along the line of high resistance corona-prevention belt is of a size of 160mm, and the anticorona coating overlap distance is 20mm; The corona-prevention belt initiating terminal 20mm that makes progress begins from half-lap, the terminal 20mm place downwards of paramount resistance corona-prevention belt only half-lap one deck mica tape as supplementary insulation; On supplementary insulation, the high resistance corona-prevention belt of half-lap one deck, starting point is from 15mm beginning before the supplementary insulation head end to finishing apart from lead-in wire 210mm place.Its level is many, each bed thickness, and whole thick, cost is high.
Summary of the invention
In order to overcome defects, the purpose of this invention is to provide a kind of VPI stator bar.
To achieve these goals, the present invention adopts following technical scheme:
A kind of VPI stator bar, it is comprised of straight line portion and two ends, straight line portion comprises wire guide plate, transposition spacer, transposition is filled, bar insulation, interior equalizing press layer, insulation against ground, anti-corona processing, supplementary insulation, electromagnetic wire, bar insulation coated wire plate, transposition spacer is installed the bar insulation two side ends, electromagnetic wire coats bar insulation and transposition spacer, transposition is filled and is fixed on two side ends, interior equalizing press layer, insulation against ground, anti-corona processing, supplementary insulation coats said structure successively, the end comprises conductive plate, bar insulation, interior equalizing press layer, insulation against ground, anti-corona processing, supplementary insulation, electromagnetic wire, bar insulation coated with conductive plate, electromagnetic wire is two wide ends of bar insulation fixedly, interior equalizing press layer, insulation against ground, anti-corona processing, supplementary insulation coats said structure, transposition spacer is the polyester fiber non-woven fabric polyester film compound material, and it is that the thermoset epoxy semiconductor is filled the putty plate that transposition is filled, bar insulation is many glue of epoxy glass prepreg felt, interior equalizing press layer is the low resistance epoxy glue, insulation against ground is epoxy little-glue glass dust mica tape, anti-corona processing is low resistance semiconductor glass tape and high ohmic semiconductor glass tape, supplementary insulation is XT0502-2, electromagnetic wire is double glass fiber bag sintering line.
The thickness of polyester fiber non-woven fabric polyester film compound material is 0.25 meter, the thickness of many glue of epoxy glass prepreg felt is 0.30 meter, the thickness of the few glue glass dust mica tape of oxygen is 0.14 meter, the thickness of low resistance semiconductor glass tape is 0.09 meter, the thickness of high ohmic semiconductor glass tape is 0.13 meter, and supplementary insulation is that the thickness of XT0502-2 is 0.20 meter.
The main feature of VPI stator bar of the present invention: (1) few glue insulation mica content is higher, increased the insulation electrical life, few glue insulation mica tape material mostly is single-side reinforced, and supporting material content generally about 8.5%, adopts the above mica paper of quantitative 160g/m2, mica content is 80%, after the VPI PROCESS FOR TREATMENT, impregnating resin enters insulating barrier, the glue content increase, but mica content still can reach more than 65%, and the glue insulation is high a lot of than manying.Because therefore the irreplaceable corona resistance that mica has is lacked glue insulated electro aging life-span and will be grown.(2) VPI technique is used in few glue insulation.When vacuumizing, the low molecular weight volatile thing in the insulating barrier air gap is easily eliminated, and is in vacuum state.When pressure impregnation, resin easily enters, and insulating barrier is well filled.Even have some very small spaces to fill not exclusively, also be in vacuum state.Reduce in the insulating barrier space, and pressure decreased will inevitably improve the inner free field intensity of insulation, thereby increase electrical life.(3) labor productivity of few glue VPI insulating process is more much higher than the glue of manying insulating process.Level of the present invention is few, and each layer is thin, and is whole thin.
