00:00:16,390 --> 00:00:19,130
接通 103 和 105

9
00:00:19,130 --> 00:00:24,050
105的线通过航空插头到达真空断路器VS1的常闭点

10
00:00:24,053 --> 00:00:28,733
该常闭点用于防止断路器处于合闸状态时再次合闸

11
00:00:28,733 --> 00:00:30,383
接到合闸电磁铁

12
00:00:30,386 --> 00:00:33,096
合闸电磁铁得电吸合用于合闸

13
00:00:33,096 --> 00:00:34,946
当按动分闸按钮时

14
00:00:34,946 --> 00:00:36,106
133得电

15
00:00:36,106 --> 00:00:39,240
通过航空插头到达断路器常开触点

16
00:00:39,240 --> 00:00:43,010
该常开触点用于防止分闸状态时再次分闸

17
00:00:43,010 --> 00:00:44,720
接通分闸电磁铁

18
00:00:44,720 --> 00:00:45,620
用于分闸

19
00:00:45,626 --> 00:00:47,666
当切换到远程控制时

20
00:00:47,666 --> 00:00:49,086
13号线接通

21
00:00:49,086 --> 00:00:51,933
通过远程操作箱或者国网平台

22
00:00:51,933 --> 00:00:55,443
或者自动化PLC DCS 等控制分合闸

23
00:00:55,443 --> 00:00:56,798
合闸指示灯HG

24
00:00:56,798 --> 00:01:00,853
通过连接一个真空断路器的常开点用于指示合闸

25
00:01:00,853 --> 00:01:04,643
分闸指示灯HR连接一个真空断路器的常闭点

26
00:01:04,643 --> 00:01:05,993
用于指示分闸
