This shows the flow of the refrigerant. The rotating electric machine is roughly divided into a rotor 1 coupled to a main shaft, which is a rotating shaft not shown, and a stator 2 installed on a foundation of a power generation facility also not shown. The rotor 1 is provided with a rotor core 4 from a main shaft via a rotor spoke 3, and a rotor winding (rotor winding) 5 is embedded on an outer peripheral side surface of the rotor core 4.

えるように構成されている。FIG. 10 is a schematic enlarged sectional view of the vicinity of the winding end of the wound rotor of FIG. On the inner peripheral side of the rotor winding end 6 at the end of the rotor core 4, there is provided a support ring supporting portion 12 arranged at intervals in the circumferential direction with respect to the rotation axis. Between the rotor winding end 6 and the support ring support portion 12, a support ring 13 is laminated and fitted in the direction of the rotation axis via a spacing piece. And it has a "U" shape,
The U-bolt 7 is formed so that both ends can be tightened by nuts. The ends of the U-bolt 7 are sequentially inserted from outside the winding end 6 so as to sandwich the rotor winding 5 and the support ring 13. An end is fixed by a nut via a saddle 14 on the inner diameter side. In this way, the rotor winding end 6 is fixed to the support ring 13 by the U bolt 7, and the inner diameter side of the support ring 13 is fixed to the support ring support 12 fixed to the end of the iron core 4 over the circumferential direction of the rotating shaft. Therefore, as a result, the rotor 1 is configured to have a resistance to the centrifugal force acting when the rotor 1 rotates.

る。In the operation state of the rotating electric machine, the rotor,
The windings provided on each of the stators are energized, and Joule heat is generated there, thereby increasing the temperature inside the machine. This is because the rotating electric machine is sealed by a cover (not shown). If the temperature inside the machine rises, it adversely affects the insulation coating of the windings and the like. Therefore, the refrigerant inside the machine is circulated, and the temperature inside the machine is lowered by passing through the cooler 15 provided inside the machine. The circulation path of such a refrigerant is shown below, including the circulation path A in FIG. That is,
The refrigerant flowing out of the cooler 15 is guided toward the center of the rotor 1 (to the left in FIG. 9) by the fan effect caused by the rotation of the rotor 1, flows into the rotor core 4, and flows into the rotor core 4. The rotor winding 5 is cooled together with the rotor core 4 and guided to an air gap 16 formed by the rotor core 4 and the stator core 9. Part of the refrigerant guided to the air gap 16 flows into the stator core 9, and the stator core 9 and the stator windings 1.
After cooling 0, it circulates in the machine on the route to the cooler 15.

The refrigerant guided to the core end exchanges heat with the rotor winding end 6 and the stator winding end 11 and then circulates in the machine on the path to the cooler 15 as shown in the ventilation path B. .

７での風損が大きくなる。However, with the rotation of the rotor 1 due to the operation of the rotating electric machine, the air gap is caused by the fan effect of a series of winding supporting structures 17 fixing the rotor winding end 6. The refrigerant guided to the core end along the portion 16 may not circulate through the ventilation path B and form a circulation path C that does not pass through the cooler 15. When the rotating electric machine is operated in a state in which the circulation path C is formed, since the refrigerant in the machine does not pass through the cooler 15, the heated refrigerant overheats the rotor winding end 6. Therefore, there is a concern that the insulating material of the rotor winding end 6 is adversely affected. In addition, since the refrigerant loops through the circulation path C, the flow rate of the refrigerant passing through the winding support structure 17 becomes relatively excessive as compared with other portions.
7, the windage increases.

If you use a bind wire instead of a bolt,
Although it takes a lot of man-hours to attach and detach the rotor winding end 6, a gap formed by combining the winding ends in a mesh shape,
The gap is closed by binding with a binding line. Therefore, the circulation path C is not formed by closing the gap.

Further, the ventilation adjusting plate 20 is provided with a ventilation adjusting plate opening 23 for guiding the refrigerant flowing out of the cooler 15 through the circulation path A to a space in which the stator winding end 11 is surrounded by the ventilation adjusting plate 20. Further, a cover plate 24 for adjusting the degree of opening and closing of the ventilation adjusting plate opening 23 is provided in the circumferential direction of the ventilation adjusting plate 20.

られることは無論である。In the rotating electric machine of the present embodiment configured as described above, when the air gap 16 is guided to the end of the iron core by passing through the rotor core 4 through the circulation path A, the ventilation The provision of the adjusting plate protrusion 21 enables adjustment and restriction of the flow path of the refrigerant formed by the rotor winding end 6 and the ventilation adjusting plate 20, so that the refrigerant does not flow into the cooler 15. The formation of the circulation path C through which the excess refrigerant circulates through the winding supporting structure 17 can be suppressed. In addition, the low-temperature refrigerant before heat exchange with the rotor is replaced with the high-temperature refrigerant guided to the cooler 15 through the ventilation path B by the blocking plate 2 serving as the flow rate adjusting means 22.
By leading to the stator winding end 11 from the ventilation adjusting plate opening 23 while adjusting at 4, the end of the stator core 9 and the stator winding end 11 can also be appropriately cooled. Therefore,
By suppressing the formation of the circulation path C, an abnormal overheating of the winding end due to the circulation of the high-temperature refrigerant through the rotor winding end 6 and the amount of air flow in the winding support structure 17 are made appropriate. Thus, windage loss in the winding support structure 17 can be suppressed. Needless to say, the same effect can be obtained even when the ventilation adjusting plate 20 and the ventilation adjusting plate protrusion 21 are integrally formed.

Both the present embodiment and the first embodiment prevent the formation of the circulation path C, but include a brush seal portion 26 provided via a ventilation adjusting plate 20 provided on the stator frame 8, This prevents the refrigerant in the machine from flowing in the direction of the rotating shaft, bypassing the rotor winding end 6 from the outer peripheral side.
