Description
Technical field
The utility model relates to the gen-set field, especially a kind of high-voltage generator of high efficiency low wind resistance.
Background technology
Generator is converted to electric energy with mechanical energy, and portion of energy is converted into the rising that heat energy causes the generator temperature.The wind path design of existing high-voltage generator inside is unreasonable, and especially the stator core internal temperature rise is higher to cause internal temperature rise.As shown in Figure 1, the rotor core 5 of existing high-voltage generator is installed in the rotating shaft 8 of support 1, and rotor coil 7 is wound in the rotor core 5; In the periphery of rotor core 5, be fixed with stator core 3 at support 1 inner chamber, stator coil winding is in the flute profile of stator core 3; Leave air gap 4 between rotor and the stator.The mentality of designing of the inside wind path of existing high-voltage generator is that the air of cooling enters from the air-inlet window 9 of support 1 both sides, carry out air-cooled to inner heating element especially stationary part, referring to Fig. 1, the original idea of wind path design wishes to flow to II section from most of cold air of I section, and stator is cooled off; Flow out from air outlet window 10 at last.But during real work, because end, inlet side winding 2 unsealings, most of cold air of I section directly flow to III section from winding 2 spaces, end, inlet side, and flows to the rear portion by air gap 4 and pole clearance 15, can not carry out efficiently radiates heat to stator; Also can be owing to leading and pass through air that stator arrives II section, and directly flow to V section, can not carry out efficiently radiates heat to end, air side winding 6.In addition, because stator core does not arrange air duct, its radiating effect also is very limited.End, air side winding 6 is not provided with support at the place, end simultaneously, is subjected to deform easily in the situation of magnetic pull, causes winding to burn out.Therefore, because there are above-mentioned " wind short circuit " phenomenon in many places, caused radiating effect undesirable, the generator temperature rise is generally higher, especially under some hot environments, even has caused the overheated of generator to burn and equipment fault.
The utility model content
The applicant is unreasonable for the wind path design of above-mentioned existing high-voltage generator inside, the shortcoming such as cause internal temperature rise especially the stator core internal temperature rise be higher, a kind of high-voltage generator of high efficiency low wind resistance rational in infrastructure is provided, thereby the raising radiating effect guarantees the operation of generator long time stability ground.
The technical scheme that the utility model adopts is as follows:
A kind of high-voltage generator of high efficiency low wind resistance, stator core are provided with the radial ventilation ditch that radiation is dispersed; In the winding of the end, inlet side of stator core, be provided with the end filling; In the end, air side of stator core winding arranged outside deep bead and the air baffle ring of annular are arranged, air baffle ring is fixed on the inwall of support by deep bead, settles centrifugal fan at the air outlet window place.
As further improvement in the technical proposal: the groove width of described ventilation ducts is 10 ± 2mm.
The beneficial effects of the utility model are as follows:
The utility model is by arranging padding in the winding of end, inlet side, winding arranges deep bead and air baffle ring in the end of air side, and be provided with the radial ventilation ditch that radiation is dispersed in stator core, thereby formed rational wind path at generator, avoid polytopic " wind short circuit " phenomenon, to internal component, especially stationary part dispels the heat effectively.Through test relatively, stator core internal temperature rise of the present utility model is lower than design load, temperature rise to improve effect more obvious, the winding overhang temperature rise is normal, does not worry in use that temperature rise is too high to cause the motor harmful effect; In addition, the end portion supports of winding is set, can greatly reduces winding and be damaged because of the moment of torsion that magnetic circuit produces.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 3, Figure 4, stator core 3 of the present utility model is separated by partition 17, forms the radial ventilation ditch 12 that radiation is dispersed, and the groove width of ventilation ducts 12 is about 10mm.In the side of stator core 3 near air-inlet window 9, in end, air side winding 6, be provided with the end filling 11 of suitable shape felt material; In stator core 3 side near air outlet windows 10, be welded with the deep bead 13 of loop configuration at the inwall of support 1, air baffle ring 16 is fixed on the deep bead 13, is positioned at the outside of end, air side winding 6.Settle centrifugal fan 14 at air outlet window 10 places.
During real work, under the exhausting of centrifugal fan 14, cold wind enters from the anti-drive end side plate air-inlet window 9 of support 1, and air gap 4 and the pole clearance 15 of part cold wind between rotor flows to IV section from III section, owing to offered multiple tracks radial ventilation ditch 12 in the stator core 3, therefore windage is less, the part cold wind of the I section ventilation ducts 12 of flowing through, and through air gap 4 and pole clearance 15 to IV sections, therefore can dispel the heat timely to stationary part, prevent that it is overheated.I section flow to the air of II section, because stopping of deep bead 13 and air baffle ring 16 arranged, " wind short circuit " can not occur directly to be siphoned away by fan 14, can only between the slit of end, air side winding 6 by flowing to IV section, thereby can dispel the heat by force to this part, reduce better the temperature rise of end windings and parts.
According to the reality test, adopt the high-voltage generator of the utility model wind path structure, its temperature rise is lower than the about 8～10K of traditional wind path structure.Air baffle ring 16 is glass steel material; be centered around the outside of end, air side winding 6; not only can form the wind path of optimization; and end, air side winding 6 also there is good mechanical protection effect; and can prevent leakage field; reduce end leakage reactance, need not consider the over the ground creepage distance of winding overhang, and can reduce ventilation noise.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and in the situation of the utility model spirit, the utility model can be done any type of modification.
