00:00:06,350 --> 00:00:07,280
电压电器

4
00:00:07,280 --> 00:00:09,440
在110千伏线路中

5
00:00:09,440 --> 00:00:11,270
它往往配合断路器

6
00:00:11,270 --> 00:00:13,210
用于分合和隔离线路

7
00:00:13,210 --> 00:00:15,090
以及对线路可靠接地

8
00:00:15,093 --> 00:00:18,483
保证了倒闸操作的严谨性和安全性

9
00:00:18,483 --> 00:00:20,203
上端触头为进线

10
00:00:20,203 --> 00:00:21,483
中间为出线

11
00:00:21,483 --> 00:00:24,633
折叠运动和夹紧运动复合协同设计

12
00:00:24,640 --> 00:00:27,746
兼顾了操作效率与电气稳定性

13
00:00:27,747 --> 00:00:31,127
它由隔离刀闸系统和接地系统组成

00:00:31,127 --> 00:00:33,397
隔离刀闸用于分合线路

15
00:00:33,397 --> 00:00:36,133
接地系统用于给线路做可靠接地

16
00:00:36,133 --> 00:00:39,563
隔离刀闸又分为操作机构和执行机构

17
00:00:39,563 --> 00:00:42,800
他俩之间通过机械的紧密配合去实现

18
00:00:42,800 --> 00:00:47,627
操作机构是将电能 通过电机旋转转换成机械能

19
00:00:47,627 --> 00:00:50,447
电机运转带动涡轮减速机运转

20
00:00:50,447 --> 00:00:54,107
减速后经齿盘带动竖轴及旋转瓷瓶旋转

21
00:00:54,107 --> 00:00:57,587
联动水平横杆和其他俩旋转瓷瓶运动

22
00:00:57,587 --> 00:00:59,797
迫使大臂向上做切线运动

23
00:00:59,800 --> 00:01:02,070
并压缩内部的弹簧储能

24
00:01:02,070 --> 00:01:05,020
经齿盘带动二臂同样向上伸展

25
00:01:05,020 --> 00:01:07,040
夹头碰到上端线路后

26
00:01:07,040 --> 00:01:09,780
大臂指尖压缩二臂里面的触杆

27
00:01:09,780 --> 00:01:11,940
从而让夹头夹紧线路

28
00:01:11,940 --> 00:01:13,907
并压缩内部弹簧储能

29
00:01:13,907 --> 00:01:15,747
从而完成合闸

30
00:01:15,747 --> 00:01:16,817
分闸时

31
00:01:16,817 --> 00:01:18,657
电机会反方向运转

32
00:01:18,657 --> 00:01:21,747
在机械能和里面储能弹簧的能量下

33
00:01:21,747 --> 00:01:23,187
夹紧触头分开

34
00:01:23,187 --> 00:01:24,887
展臂向下收缩

35
00:01:24,887 --> 00:01:28,287
通过齿轮箱驱动上导电管做复合运动

36
00:01:28,287 --> 00:01:32,007
连杆系统改变力的方向并带动下导电管转动

37
00:01:32,013 --> 00:01:34,827
形成有明显垂直断口的分闸

38
00:01:34,827 --> 00:01:36,657
当线路需要检修时

39
00:01:36,657 --> 00:01:39,367
我们可将接地刀闸做可靠接地

40
00:01:39,367 --> 00:01:41,173
通过操作机构的电机

41
00:01:41,173 --> 00:01:44,223
将电能转换成执行机构的机械能

42
00:01:44,223 --> 00:01:47,640

00:01:57,381 --> 00:01:59,731
更为我们的安全保驾护航

48
00:01:59,731 --> 00:02:01,694
它三相一体式设计方案

49
00:02:01,694 --> 00:02:05,294
可以确保在电力系统中进行开关操作时

50
00:02:05,294 --> 00:02:08,094
三个相位的开关状态始终保持一

51
00:02:08,094 --> 00:02:09,814
提高了操作效率

52
00:02:09,814 --> 00:02:11,634
增强了系统稳定性

53
00:02:11,634 --> 00:02:14,161
