本発明は回転電機の通風装置に係り、特に、リムダクト
通風方式を採用している回転電機の通風装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a ventilation system for a rotating electrical machine, and particularly to a ventilation system for a rotating electrical machine that employs a rim duct ventilation system.

あった。The conventional rim duct ventilation system is used in low-speed rotating electric machines, and is widely used because it can reduce ventilation loss compared to rotating electric machines equipped with self-fans. However, since it does not have its own fan, it has the disadvantage that the temperature distribution in the axial direction of the stator winding, especially the temperature at the winding end portion away from the stator core, becomes high. Conventionally, this problem has been solved by arranging the rim duct, but once the rotor rim is assembled, it is almost impossible to make adjustments. Furthermore, when the amount of ventilation becomes larger than the planned amount, the loss of ventilation increases, and there is a drawback that there is no countermeasure for this.
本発明の目的は、リムダクト通風方式に通風量可変機能

調整できるようにした通風装置を提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a ventilation device in which a rim duct ventilation system is provided with a ventilation volume variable function, and the ventilation can be easily adjusted while checking the actually measured ventilation volume and ventilation distribution.

を得ることができる。In most cases, the factor that determines the amount and distribution of ventilation in a rotating electric machine that uses a rim duct ventilation system is the area of the rim duct at the inner diameter of the rotor rim. That is, this is because the pressure loss consumed in this portion accounts for a predominant proportion of the entire ventilation path. Therefore, if the area of this portion can be changed arbitrarily, the amount of ventilation and ventilation distribution can be adjusted. In order to achieve this, the present invention extends the conventional rim duct spacer shown in the figure to the inner diameter side of the rotor rim, and prepares bolt holes in advance on this inner diameter side. On the other hand, prepare a strip-shaped ventilation adjustment plate to adjust the rim duct area, and adjust the ventilation adjustment plate to the desired ventilation by tightening the bolts to the bolt holes on the inner diameter side of the duct spacer according to the actual ventilation amount. You can get the amount.

。On the other hand, a rectangular ventilation adjustment plate 6 for adjusting the area of the rim duct 2 as shown in FIG. 3 is attached to the rim duct 2 using the bolt holes of the duct spacer 5, as shown in FIG. This rectangular ventilation adjustment plate 6 is subjected to centrifugal force due to its own weight due to rotation, but this is supported by the inner diameter of the rotor rim 1 and the duct spacer 5.
There is no mechanical problem due to the attachment of the ventilation adjustment plate 6.

Since the axial temperature distribution of the stator winding is made uniform and an optimum amount of ventilation is ensured, it is also possible to reduce ventilation loss.
