In the utility model, the said mechanism of keeping out the wind comprises:
Wind deflector, it is connected with said deep bead, extends to the upper end of stator winding end;
Be arranged on the up and down chock in the slit of stator winding end;
Be arranged on the filling dividing plate between the adjacent winding of stator winding end;
Be arranged on the interior air guide ring of stator winding end lower end.
Said wind deflector is supported by an end and the fixing support bar of stator; The upper end contact position filling of wind deflector and deep bead and stator winding end has silica gel, to increase air-tightness.
In the utility model, said rotor interior wing extends to interior air guide ring lower end, and rotor interior wing top edge and the direct gap of interior air guide ring lower limb are less than 10mm, and preferable mode is that rotor interior wing top edge and the direct gap of interior air guide ring lower limb are 5-8mm.
In the utility model, stator and rotor are provided with corresponding radial ventilation ditch.
The mesohigh induction machine of the utility model; The project organization that separates with the end hot-fluid through line part; Cooling descends the equilibrium temperature point of heat fast, thereby reduces whole temperature rise, promotes electric efficiency; Solve the heat dissipation problem of high-voltage motor winding overhang and whole motor, reached the purpose of motor miniaturization simultaneously.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the keep out the wind enlarged diagram of mechanism of the utility model.
Embodiment
For the technological means, the creation characteristic that make the utility model, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the mesohigh induction machine that the utility model runners separates comprises framework 1, and the air inlet 2 of framework 1 is arranged on the both sides of framework 1, forms the both sides air intake; The middle part of framework 1 is provided with out one's intention as revealed in what one says 3, air outlet 3, and the utility model is isolated air inlet in the framework 12 and air outlet 3, between air inlet 2 and air outlet 3, is provided with deep bead 4, and an end of deep bead 4 and the inner surface of framework 1 are fixed.
Even also can influence air-tightness because of the gap between the stator winding 5 because deep bead 4 extends to the upper end of stator winding 5 ends, stator winding end 5 also is provided with the mechanism of keeping out the wind, and is as shown in Figure 2; The mechanism of keeping out the wind comprises wind deflector 61; One end of wind deflector 61 is connected with deep bead 4, and its other end extends to the upper end of stator winding 5 ends, in order to strengthen the constant intensity of wind deflector 61; Wind deflector 61 is supported by an end and the fixing support bar 62 of stator; Simultaneously, in order further to strengthen air-tightness, wind deflector 61 has silica gel 63 with the upper end contact position filling of deep bead 4 and stator winding 5 ends; Be arranged on 5 at the stator winding end chock 64 in the slit up and down; Be arranged on the filling dividing plate 65 between the adjacent winding in stator winding 5 ends; And the interior air guide ring 66 that is arranged on lower end, stator winding 5 end.
The end of the utility model rotor is provided with rotor interior wing 7; Rotor interior wing 7 extends to interior air guide ring 66 lower ends; Rotor interior wing 7 top edges and the direct gap of interior air guide ring 66 lower limbs are less than 10mm, and preferable mode is that rotor interior wing 7 top edges and the direct gap of interior air guide ring 66 lower limbs are 5-8mm; In addition, also be provided with corresponding radial ventilation ditch 8 on rotor and the stator.
The mesohigh induction machine of the utility model, motor is when operation, through the rotation of rotor interior wing 7; Form negative pressuren zone in the rotor both sides; This negative pressure is the outside cold wind of motor, or through the interior gas that subcooler cool off, passes through framework 1 two ends air inlet 2 inspiration motor ends.Part cold wind gets into the rotor core septa area by the rotor radial ventilation ducts; After taking away heat through air gap entering stator core septa area again; Blow to the outside or cooler of motor; Need in the stator winding between air guide ring 66 and the rotor interior wing 7 keep a less clearance, also are to come back to negative pressuren zone for fear of cold wind through this gap to form sinuous flow, can have a strong impact on cooling effect as forming sinuous flow.
Another part cold wind access path is for pass through side clearance in stator winding 5 ends through rotor interior wing 7 again; After taking away the heat of winding overhang; Blow to the outside or cooler of motor; Like this, cooling air quantity gets into separated into two parts path, back in the motor body, reaches the purpose of quick cooling motor integral body and stator winding end.
