An outgoing line of the stator winding is welded with a connecting cable line, dripping impregnating insulated paint is dripped and injected inside the stator winding, a dripping impregnating insulated paint film is wholly wrapped outside the stator winding, pluralities of layers of flexible insulated belts are wound and wrapped at connection positions of the ongoing line and the connecting cable line of the stator winding, and a rubber sleeve is sleeved outside the insulated belts. A motor assembled via the stator winding is guaranteed to run safely and reliably on conducting liquid media with high temperature of 210 DEG C and high pressure of 20 MP a, and the stator winding has the advantages of simple structure, convenient operation, low manufacturing cost, strong reliability and the like.
Description
Technical field
The utility model belongs to technical field of motors, and particularly a kind of being applicable to encapsulates motor stator winding in the insulation of using in the high pressure conductive fluid medium.
Background technology
In the prior art, the shaft extension end bearing position of sealability, particularly electric machine main shaft that general motor does not bear high pressure fluid, its sealing can only prevent the immersion of dust and low discharge rainwater.And along with the modernization development of science and technology, the service environment of electric equipment products becomes increasingly complex, and the motor such as installing and using up to 200 ℃, in the conductive fluid medium of pressure 20MPa in temperature can't stop the immersion of liquid medium at all.In case the high pressure conductive fluid medium enters electric machine casing, then cause stator winding and pigtail splice position failure of insulation thereof easily, cause burning machine fault.Because by the sealing of electric machine casing realization to highly pressurised liquid, its difficulty is big especially, does not therefore at present also have to satisfy the motor technology that uses in the HTHP conductive fluid medium, is seriously restricting the development of relevant art.
The utility model content
The purpose of this utility model provides a kind of can installing and using in the conductive fluid medium of HTHP, and encapsulation motor stator winding in the insulation safe and reliable to operation.
Realize that the technical scheme that the purpose of this utility model is taked is: this stator winding has stator winding and stator core, the lead-out wire of stator winding and jump lead line are welded to connect, wherein, stator winding inner instil to have to drip soak insulating varnish, the stator winding external overall is coated to be had to drip and soaks the insulation paint film, stator winding lead-out wire and twine with the connecting portion of jump lead line and to be enclosed with the layer flexible insulating tape, the insulating tape outer cover is equipped with gum sleeve, and twines successively in the gum sleeve outside and to be enclosed with flexible insulation band and glass strap.
Described thickness that soaks the insulation paint film is 1～3mm.
Described flexible insulation band adopts many rubber powders mica tape, and thermal endurance class is more than the C level.
Described is soaked insulating varnish employing solvent-free dripping impregnating varnish, and thermal endurance class is more than the C level.
Described gum sleeve adopts fluorine rubber-pipe or silicone rubber tube.
Encapsulate motor stator winding in the insulation according to the such scheme making, by the multilayer parcel that dripping of stator winding and lead-out wire and jump lead line soaked insulation and insulating tape, can guarantee motor safe and reliable operation in 210 ℃ of high temperature and 20MPa high pressure conductive fluid medium, and have simple in structure, easy to operate, cheap, advantages such as good reliability.

Fig. 2 is the local enlarged diagram of A-A among Fig. 1;
Fig. 3 is the structural representation of stator winding lead-out wire and jump lead line connecting portion.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the encapsulation motor stator winding has stator winding 3 and stator core 4 in the insulation of the present utility model, and the label 1 among the figure is the leading-out terminal of stator winding 3, and label 2 is the end of incoming cables of stator winding 3, and label 5 is the stator winding end coil.In order to prevent after the high pressure conducting liquid enters motor field frame, stator winding coil 5 failure of insulation take place and cause short trouble, in the gap of stator winding 3 inner each electromagnetic wire 6, instillation is filled with solvent-free dripping impregnating varnish 7, electromagnetic wire 6 is carried out insulating protection, the thermal endurance class of this dripping impregnating varnish is more than the C level, and heat resisting temperature is more than 210 ℃.The solvent-free dripping impregnating varnish that instils is the insulation paint film 8 of 1～3mm at stator winding 3 outside its thickness that form integrated cladding also, stator winding lead-out wire 9 and twine with the connecting portion of jump lead line 14 and to be enclosed with layer flexible insulating tape 10,12,17, this flexible insulation band adopts is to have insulation, softness, many rubber powders mica tape of characteristic such as wear out, its thermal endurance class is more than the C level, and heat resisting temperature is more than 210 ℃.The mode of concrete insulation is: be enclosed with gum sleeve 11 of suit on the stator winding lead-out wire 9 of flexible insulation band, this gum sleeve 11 can adopt fluorine rubber-pipe or the silicone rubber tube with good heat resistance and anti-aging characteristic.Then with stator winding lead-out wire 9 and jump lead line 14 corresponding being welded to connect, carrying out pretension with the insulation rubber tube 15 of 16 pairs of jump lead lines 14 of iron wire again ties up, and at least 1 layer of flexible insulation band 17 of welding position parcel, mobile then gum sleeve 11 overlaps with the insulation rubber tube 15 of jump lead line 14, again at gum sleeve 11 outer wrap one deck flexible insulation band 12 and one deck glass straps 13.By the winding parcel of butted line position layer flexible insulating tape 10,17 and the Apparatus for strapping packages of gum sleeve 11 outside flexible insulation bands 12 and glass strap 13, stator winding lead-out wire 9 is closely engaged with the insulation rubber tube 15 of jump lead line 14 be one, and with insulation rubber tube 15 breathing of jump lead line 14, thereby prevent the immersion of high pressure conductive fluid medium effectively, and guaranteed the insulation effect at this position.In addition, by being dripped, the globality of stator winding 3 soaks insulation-encapsulated, can make the electromagnetic wire 6 isolated fully and insulation in the stator winding 3 with high hydraulic pressure conductive fluid medium, and the motor that uses this stator winding to assemble, its insulated enclosure performance can reach the result of use of safe and reliable operation in the high pressure conductive fluid medium of 210 ℃ of high temperature and 20Mpa fully.
