1
00:00:00,000 --> 00:00:02,930
KYN28柜属于中置式开关柜

2
00:00:02,930 --> 00:00:05,400
该型开关柜主要用于10kV

3
00:00:05,400 --> 00:00:08,360
6kV等电力系统的电能分配与控制

4
00:00:08,360 --> 00:00:10,245
通过金属板材拼接

5
00:00:10,245 --> 00:00:11,350
将低压室

6
00:00:11,350 --> 00:00:12,415
断路器式

7
00:00:12,415 --> 00:00:13,345
母线室

8
00:00:13,345 --> 00:00:14,775
电缆式等隔离

9
00:00:14,775 --> 00:00:15,893
模块化设计

10
00:00:15,893 --> 00:00:18,333
确保了各功能区互不干扰

11
00:00:18,334 --> 00:00:21,609
操作系统和智能组合电气可灵活搭配

12
00:00:21,609 --> 00:00:22,734
实现操控

13
00:00:22,734 --> 00:00:23,514
检测

14
00:00:23,514 --> 00:00:24,600
保护等功能

15
00:00:24,600 --> 00:00:28,560
通过高压断路器实现电路的接通、分断及保护

16
00:00:28,561 --> 00:00:30,516
并且派生出了计量柜

17
00:00:30,516 --> 00:00:31,386
PT柜

18
00:00:31,386 --> 00:00:32,431
进线柜等

19
00:00:32,431 --> 00:00:35,614
组合后让其成为整套高压柜的不二之选

20
00:00:35,614 --> 00:00:37,624
相较于固定式开关柜

21
00:00:37,624 --> 00:00:39,789
采用小车式断路器结构

22
00:00:39,789 --> 00:00:41,667
便于设备的维护与更换

23
00:00:41,667 --> 00:00:44,472
提升了操作灵活性和检修效率

24
00:00:44,472 --> 00:00:46,662
五防连锁机构的可靠设计

25
00:00:46,662 --> 00:00:48,552
也保证了设备和人员的安全

26
00:00:49,095 --> 00:00:51,268
现在模拟一下他的操控

27
00:00:51,268 --> 00:00:53,441
检修位置到试验位置

28
00:00:53,441 --> 00:00:56,335
首先将断路器放到移动手车上

29
00:00:56,335 --> 00:00:59,095
然后将手车调整到合适高度

30
00:00:59,095 --> 00:01:01,761
将手车插到连接控并锁死

31
00:01:01,762 --> 00:01:03,842
双手向里推动拉杆

32
00:01:03,842 --> 00:01:06,028
听到咔哒声后往里推

33
00:01:06,028 --> 00:01:07,962
缓慢将手车推入

34
00:01:07,962 --> 00:01:11,215
松开双手让手柄自复位卡进锁孔

35
00:01:11,215 --> 00:01:12,908
插上航空插头

36
00:01:12,908 --> 00:01:16,068
用手车摇把向里推动并缓慢摇动

37
00:01:16,069 --> 00:01:17,815
听到机械咔哒声

38
00:01:17,815 --> 00:01:19,535
并观察指示面板

39
00:01:19,535 --> 00:01:21,589
看到面板指示灯亮起

40
00:01:21,589 --> 00:01:23,469
说明到达实验位置

41
00:01:23,469 --> 00:01:25,802
实验位置到达工作位置

42
00:01:25,802 --> 00:01:28,269
首先需观查两个先决条件

43
00:01:28,269 --> 00:01:31,069
指示面板接地刀闸是否在合位

44
00:01:31,069 --> 00:01:33,389
如果合位需先分开刀闸

45
00:01:33,389 --> 00:01:35,669
观查断路器是否在分位

46
00:01:35,669 --> 00:01:37,069
如果在合位

47
00:01:37,069 --> 00:01:38,762
需先手动分闸

48
00:01:38,762 --> 00:01:40,215
满足条件后

49
00:01:40,216 --> 00:01:42,096
可以继续摇动摇把

50
00:01:42,096 --> 00:01:43,936
随着断路器往里进

51
00:01:43,936 --> 00:01:46,309
活门在底部杠杆下打开

52
00:01:46,310 --> 00:01:47,910
梅花插头进入

53
00:01:47,910 --> 00:01:49,656
直到一声咔哒声

54
00:01:49,656 --> 00:01:51,256
摇把明显卡顿

55
00:01:51,256 --> 00:01:52,110
摇不动

56
00:01:52,110 --> 00:01:54,683
指示面板显示进入工作位置

57
00:01:54,683 --> 00:01:56,256
说明到达位置

58
00:01:56,256 --> 00:01:58,163
摇动时如果摇不动

59
00:01:58,164 --> 00:01:59,444
则需停止

60
00:01:59,444 --> 00:02:01,804
检查机械结构是否卡顿

61
00:02:01,804 --> 00:02:04,417
然后再进行分合闸操作即可
