00:00:00,000 --> 00:00:03,660
1:该二次线路具备手动本地分合闸功能

2
00:00:03,660 --> 00:00:04,910
用于本地操作

3
00:00:04,910 --> 00:00:06,080
远程分合闸

4
00:00:06,080 --> 00:00:10,960
用于远程自动化或者国网平台或者远控箱分合闸功能

5
00:00:10,960 --> 00:00:14,250
当分合闸旋钮kk打到本地控制时

6
00:00:14,250 --> 00:00:15,910
可旋至手动合闸

7
00:00:15,910 --> 00:00:17,706
让KK1   2接通

8
00:00:17,706 --> 00:00:21,120
使合闸线圈HQ吸合 用于合闸

9
00:00:21,120 --> 00:00:27,480
当旋钮钮到分闸时 11   12端子接通 使分闸线圈TQ跳闸

10
00:00:27,480 --> 00:00:32,440
当选至远程时5      6端子接通 7      8端子接通

00:00:38,140 --> 00:00:40,093
去分合闸断路器

15
00:00:40,094 -->00:00:40,095
 

16
00:00:40,095 --> 00:00:43,664
2:该线路可通过接入微机综合保护器

17
00:00:43,664 --> 00:00:46,724
让其具备两套独立的二次重合闸功能

18
00:00:46,724 --> 00:00:49,534
和两套独立的远程跳闸功能

19
00:00:49,534 --> 00:00:54,944
来自两套独立的微机保护器的重合闸常开点HJ1和HJ2

20
00:00:54,944 --> 00:00:56,494
可使意外跳闸时

21
00:00:56,494 --> 00:00:59,507
根据微保设置 来一次重合闸

22
00:00:59,508 --> 00:01:01,368
当不想利用该功能时

23
00:01:01,368 --> 00:01:02,598
或者检修时

24
00:01:02,598 --> 00:01:04,298
可挑其保护连片

25
00:01:04,298 --> 00:01:06,528
远程跳闸TJ1和TJ2

26
00:01:06,528 --> 00:01:10,321
保护跳闸入口可接入两套独立的微机保护

27
00:01:10,322 --> 00:01:12,282
或者其他保护继电器

28
00:01:12,282 --> 00:01:15,292
有的也会接入两套独立的跳闸线圈

29
00:01:15,292 --> 00:01:17,175
用于需要跳闸时的跳闸

30
00:01:17,175 --> 00:01:20,842
其中微机保护中的设置保护参数需一致

31
00:01:20,842 --> 00:01:20,843


32
00:01:20,843 --> 00:01:23,482
3:该线路具备防跳跃功能

33
00:01:23,482 --> 00:01:26,668
TBJV继电器在断路器分闸时吸合

34
00:01:26,668 --> 00:01:29,598
通过它的辅助触点串入合闸回路

35
00:01:29,598 --> 00:01:33,642
防止在跳闸过程中又有合闸命令而损坏机构

36
00:01:33,642 --> 00:01:33,643


37
00:01:33,643 --> 00:01:37,752
4:KKJ是合后继电器也称磁保持继电器

38
00:01:37,752 --> 00:01:38,612
通过D1、

39
00:01:38,612 --> 00:01:42,932
D2两个二极管的单相导通性能来保证只有手动合闸

40
00:01:42,932 --> 00:01:44,162
才能让其动作

41
00:01:44,162 --> 00:01:46,072
动作后不自动返回

42
00:01:46,072 --> 00:01:49,632
手动跳闸或者自动合闸后才能让其复归

43
00:01:49,642 --> 00:01:52,055
其接点可以用于重合闸

44
00:01:52,056 --> 00:01:52,057


45
00:01:52,057 --> 00:01:56,366
5:HYI与TYJ是合闸和跳闸压力继电器

46
00:01:56,366 --> 00:01:58,696
接入断路器机构的气压接点

47
00:01:58,696 --> 00:02:02,116
在以六氟化硫为灭弧绝缘介质的开关中

48
00:02:02,116 --> 00:02:04,429
如果六氟化硫气体有泄露

49
00:02:04,429 --> 00:02:09,189
则当气体压力降至危及灭弧时该接点T1和T2导通

50
00:02:09,189 --> 00:02:10,849
将操作回路断开

51
00:02:10,856 --> 00:02:12,176
禁止操作

52
00:02:12,176 --> 00:02:12,177


53
00:02:12,177 --> 00:02:14,316
6:位置继电器HWJ

54
00:02:14,316 --> 00:02:16,706
TWT的作用有两个

55
00:02:16,706 --> 00:02:18,789
一是显示当前开关位置

56
00:02:18,789 --> 00:02:21,736
二是监视跳、合线圈是否完好

57
00:02:21,736 --> 00:02:21,737


58
00:02:21,737 --> 00:02:24,526
7:控制电源采双电源系统

59
00:02:24,526 --> 00:02:26,166
利用JJ继电器

60
00:02:26,166 --> 00:02:28,562
当一号直流屏电源KM1

61
00:02:28,562 --> 00:02:32,176
失电后 自动切换到备用电源KM2
