00:00:00,000 --> 00:00:01,050
¿Cómo hace un motor

2
00:00:01,050 --> 00:00:02,210
de avión para darle

3
00:00:02,210 --> 00:00:03,610
luz a una planta?

4
00:00:03,610 --> 00:00:04,450
Una turbina

5
00:00:04,450 --> 00:00:05,690
aeroderivada nace de

6
00:00:05,690 --> 00:00:06,550
un motor de avión,

7
00:00:06,550 --> 00:00:07,550
pero en tierra,

8
00:00:07,550 --> 00:00:08,350
en lugar de empujar

9
00:00:08,350 --> 00:00:08,990
un avión,

10
00:00:08,990 --> 00:00:10,630
mueve un generador.

11
00:00:10,630 --> 00:00:11,590
El compresor aspira

12
00:00:11,590 --> 00:00:12,570
aire y lo aprieta

13
00:00:12,570 --> 00:00:14,110
hasta 30 veces.

14
00:00:14,110 --> 00:00:14,790
En la cámara de

15
00:00:14,790 --> 00:00:15,550
combustión,

16
00:00:15,550 --> 00:00:16,610
ese aire se mezcla

17
00:00:16,610 --> 00:00:17,730
con gas natural y

18
00:00:17,730 --> 00:00:18,450
se quema a más

19
00:00:18,450 --> 00:00:19,950
de 1,000 grados.

20
00:00:19,950 --> 00:00:20,810
Los gases calientes se

21
00:00:20,810 --> 00:00:21,590
expanden en la

22
00:00:21,590 --> 00:00:22,430
turbina:

23
00:00:22,430 --> 00:00:23,350
una parte mueve al

24
00:00:23,350 --> 00:00:24,230
compresor,

25
00:00:24,230 --> 00:00:25,310
el resto es potencia

26
00:00:25,310 --> 00:00:26,390
en la flecha.

27
00:00:26,390 --> 00:00:27,310
Y aquí entra una

28
00:00:27,310 --> 00:00:28,390
pieza clave:

29
00:00:28,390 --> 00:00:28,910
el gearbox.

30
00:00:28,910 --> 00:00:31,010
Una turbina chica gira

31
00:00:31,010 --> 00:00:31,950
a más de 14,000

32
00:00:31,950 --> 00:00:33,210
revoluciones y el

33
00:00:33,210 --> 00:00:34,090
generador necesita

34
00:00:34,090 --> 00:00:35,470
1,800.

35
00:00:35,470 --> 00:00:36,810
La caja reductora baja

36
00:00:36,810 --> 00:00:37,870
la velocidad y sube

37
00:00:37,870 --> 00:00:38,750
el par.

38
00:00:38,750 --> 00:00:39,710
Con cuatro polos,

39
00:00:39,710 --> 00:00:41,330
a 1,800 son 60

40
00:00:41,330 --> 00:00:42,590
hercios.

41
00:00:42,590 --> 00:00:43,450
Las aeroderivadas

42
00:00:43,450 --> 00:00:44,150
grandes,

43
00:00:44,150 --> 00:00:45,790
como la LM6000,

44
00:00:45,790 --> 00:00:47,050
ya giran a 3,600

45
00:00:47,050 --> 00:00:48,150
y van directo a

46
00:00:48,150 --> 00:00:48,970
un generador de dos

47
00:00:48,970 --> 00:00:49,490
polos,

48
00:00:49,490 --> 00:00:50,630
sin gearbox.

49
00:00:50,630 --> 00:00:51,550
La microturbina

50
00:00:51,550 --> 00:00:52,830
tampoco lo usa:

51
00:00:52,830 --> 00:00:53,770
su generador de imanes

52
00:00:53,770 --> 00:00:55,070
gira a 96,000

53
00:00:55,070 --> 00:00:56,410
revoluciones y la

54
00:00:56,410 --> 00:00:56,950
electrónica de

55
00:00:56,950 --> 00:00:58,110
potencia lo entrega a

56
00:00:58,110 --> 00:00:59,530
60 hercios.

57
00:00:59,530 --> 00:01:00,330
Si falla cualquier

58
00:01:00,330 --> 00:01:01,690
pieza del tren,

59
00:01:01,690 --> 00:01:02,270
no hay energía.

62
00:01:05,330 --> 00:01:06,410
reparamos y probamos

63
00:01:06,410 --> 00:01:07,110

turbina.
