1
00:00:00,000 --> 00:00:02,045
10千伏高压柜灭弧

2
00:00:02,045 --> 00:00:05,330
断路器从工作位置到检修位置时

3
00:00:05,330 --> 00:00:08,173
当梅花触头和静触头分开瞬间

4
00:00:08,173 --> 00:00:10,233
高电压会击穿空气

5
00:00:10,233 --> 00:00:12,973
产生放电现象并形成电弧

6
00:00:12,973 --> 00:00:16,026
由于梅花触头采用多点触碰式设计

7
00:00:16,026 --> 00:00:17,961
同时断开多个回路

8
00:00:17,961 --> 00:00:20,981
电弧的能量被均摊到各个触点上

9
00:00:20,981 --> 00:00:23,786
从而每个触点上的电弧能量减小

10
00:00:23,800 --> 00:00:27,386
使得断路器的灭弧能力得到显著提高

11
00:00:27,387 --> 00:00:29,907
且动触头采用弧形设计

12
00:00:29,907 --> 00:00:32,657
让电场行成向外扩张的电场

13
00:00:32,657 --> 00:00:33,920
增加了横向力

14
00:00:33,920 --> 00:00:36,405
加上随着距离的越来越大

15
00:00:36,405 --> 00:00:39,915
使电弧在电压低于阈值时自行熄灭

16
00:00:39,915 --> 00:00:42,160
无需额外配置灭弧装置
