Description
Technical field
The utility model is related to technical field of hydraulic generators, the ventilation and heat of specifically a kind of vertical hydropower generator
System.
Background technology
In the process of running, the winding and iron core of nail will generate a large amount of heat to turbine-generator units, in order to make around
Group and the temperature of iron core are unlikely to excessively high and winding insulation are caused to damage, and turbine-generator units must be provided with ventilation cooling device.
Since turbine-generator units are to closed structure, it is therefore desirable to carry out forced heat radiation, it is common practice in generator casing
Or aerial cooler is arranged in the outside of stator, is exchanged heat to cooling water by aerial cooler, achievees the purpose that cooling.But with
The power of turbine-generator units is increasing, and the radiating rate of existing aerial cooler is difficult to continue to meet radiating requirements, needs
Aeration radiation system is improved.
Utility model content
The purpose of the utility model is to overcome the deficiency in above-mentioned background technology, a kind of vertical hydropower generator is provided
Aeration radiation system has simple in structure, lower-cost feature.
What the technical purpose of the utility model was realized in：
A kind of aeration radiation system of vertical hydropower generator, including shell, the rotor with yoke and magnetic pole, have
Several aerial coolers of the stator and installation of iron core and winding on the shell, it is characterised in that：Further include being uniformly arranged on
Two groups of main fans at yoke lower edges and both sides up and down are set in the middle part of yoke and arrange two groups of auxiliary fans of lopping, institute
State offered in yoke the air-flow conducive to auxiliary fan by cooling vent, offer conducive to main fan and auxiliary fan on stator
Air-flow by cooling vent.
The cooling vent is along the radial direction of stator or the radial arrangement of yoke.
The yoke be I-shaped yoke, in the middle part of top and bottom have it is upper and lower two enclose groove, auxiliary fan is along recessed
Cell wall on the inside of slot arranges lopping, and the covering of the fan of auxiliary fan is along the radial arrangement of yoke.
Cooling vent in the yoke penetrates into always the peripheral outer wall of yoke from the cell wall on the outside of groove.
The utility model has an advantageous effect in that：The utility model is additionally arranged on the basis of existing aerial cooler
Main fan and auxiliary fan and several cooling vents, can speed up the flowing of air-flow, to reduce the temperature of stator, it is ensured that set
Standby safe operation, overall structure is simple and practical, and cost is relatively low.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model.
Specific implementation mode
With reference to the accompanying drawings of the specification, the utility model is described in further detail.
As Fig. 1 arrive shown in a kind of aeration radiation system of vertical hydropower generator, including shell 1, have 4 and of yoke
The rotor of magnetic pole 9, several aerial coolers 2 of the stator 8 with iron core and winding and installation on the shell.Further include uniform
Two at yoke lower edges groups of main fans 3 are set and both sides up and down are set in the middle part of yoke and arrange two groups of lopping it is auxiliary
Fan 5, offer in the yoke air-flow conducive to auxiliary fan by cooling vent 7, offer conducive to main wind on stator
Fan and auxiliary fan air-flow by cooling vent 7.
The cooling vent of the stator along stator radial arrangement, the cooling vent of yoke along yoke radial direction
Arrangement.The yoke be I-shaped yoke, in the middle part of top and bottom have it is upper and lower two enclose groove 6, auxiliary fan is along groove
The evenly distributed lopping of cell wall of inside, and the covering of the fan of auxiliary fan is along the radial arrangement of yoke.Usually, main fan also along
The radial arrangement of yoke.
Cooling vent in the yoke penetrates into always the peripheral outer wall of yoke from the cell wall on the outside of groove, and upper and lower two
It encloses on the outside cell wall of groove and is respectively provided with a circle cooling vent.Stator is arranged in array in cooling vent, i.e., in stator
Circumferential lopping arrangement, in the circumferential arrayed in columns of stator.
When the rotor is turning, main fan and auxiliary fan are taken offence stream, and air-flow passes through stator from cooling vent, by stator
Heat be carried away to the outside of stator, then coordinate aerial cooler, realize cooling
The above is only the preferred embodiment of the present invention, and for those skilled in the art, this practicality is new
Type can have various modifications and variations.Within the spirit and principle of the utility model, any modification made by is equally replaced
It changes, improve, should be included within the scope of protection of this utility model.
