1
00:00:00,000 --> 00:00:00,990
La punta de estas

2
00:00:00,990 --> 00:00:01,790
aspas va a más

3
00:00:01,790 --> 00:00:03,330
de 300 km por

4
00:00:03,330 --> 00:00:03,910
hora,

5
00:00:03,910 --> 00:00:04,870
pero el rotor gira

6
00:00:04,870 --> 00:00:06,130
apenas 15 vueltas por

7
00:00:06,130 --> 00:00:06,870
minuto.

8
00:00:06,870 --> 00:00:07,830
¿Cómo sale electricidad

9
00:00:07,830 --> 00:00:09,260
de algo tan lento?

10
00:00:09,510 --> 00:00:10,730
El viento empuja 3

11
00:00:10,730 --> 00:00:11,430
aspas de más de

12
00:00:11,430 --> 00:00:12,550
50 metros,

13
00:00:12,550 --> 00:00:13,190
y cada una gira

14
00:00:13,190 --> 00:00:14,050
sobre su eje para

15
00:00:14,050 --> 00:00:14,870
tomar sólo el viento

16
00:00:14,870 --> 00:00:15,820
que necesita.

17
00:00:16,070 --> 00:00:17,230
Dentro de la góndola,

18
00:00:17,230 --> 00:00:18,310
la flecha lenta entra

19
00:00:18,310 --> 00:00:19,950
a una caja multiplicadora.

20
00:00:19,950 --> 00:00:21,050
Aquí el gearbox hace

21
00:00:21,050 --> 00:00:21,850
lo contrario que en

22
00:00:21,850 --> 00:00:22,950
una turbina de gas.

23
00:00:22,950 --> 00:00:23,870
Multiplica la velocidad

24
00:00:23,870 --> 00:00:25,230
más de 100 veces,

25
00:00:25,230 --> 00:00:26,230
de 15 a unas

26
00:00:26,230 --> 00:00:28,180
1,700 revoluciones.

27
00:00:28,310 --> 00:00:29,350
Ahí trabaja un generador

28
00:00:29,350 --> 00:00:30,810
doblemente alimentado.

29
00:00:30,810 --> 00:00:31,730
Su estator va directo

30
00:00:31,730 --> 00:00:32,490
a la red,

31
00:00:32,490 --> 00:00:33,190
y su rotor,

32
00:00:33,190 --> 00:00:33,930
a través de anillos

33
00:00:33,930 --> 00:00:34,690
rozantes,

34
00:00:34,690 --> 00:00:35,470
se conecta a un

35
00:00:35,470 --> 00:00:36,470
convertidor que maneja

36
00:00:36,470 --> 00:00:37,410
cerca de un tercio

37
00:00:37,410 --> 00:00:38,540
de la potencia.

38
00:00:38,670 --> 00:00:40,030
Así entrega 60 hercios,

39
00:00:40,030 --> 00:00:41,340
aunque el viento cambie.

40
00:00:41,470 --> 00:00:42,410
Otros diseños se eliminan

41
00:00:42,410 --> 00:00:43,170
la caja.

42
00:00:43,170 --> 00:00:44,030
Un generador de imanes

43
00:00:44,030 --> 00:00:44,810
permanentes,

44
00:00:44,810 --> 00:00:45,730
enorme y con muchos

45
00:00:45,730 --> 00:00:46,450
polos,

46
00:00:46,450 --> 00:00:47,350
gira tan lento como

47
00:00:47,350 --> 00:00:48,130
las aspas.

48
00:00:48,130 --> 00:00:49,190
Y un convertidor completo

49
00:00:49,190 --> 00:00:50,840
ajusta la frecuencia.

50
00:00:50,910 --> 00:00:52,790
El generador entrega 690

51
00:00:52,790 --> 00:00:53,450
volts,

52
00:00:53,450 --> 00:00:54,430
y un transformador eleva

53
00:00:54,430 --> 00:00:55,460
la tensión.

54
00:00:55,750 --> 00:00:57,510
Cada ráfaga castiga devanados,

55
00:00:57,510 --> 00:00:59,180
anillos y rodamientos.

56
00:00:59,470 --> 00:01:00,310
