1
00:00:00,000 --> 00:00:01,965
10千伏高压柜灭弧

2
00:00:01,965 --> 00:00:04,940
断路器从工作位置到检修位置

3
00:00:04,940 --> 00:00:06,866
当梅花触头分开瞬间

4
00:00:06,866 --> 00:00:08,271
会形成电弧

5
00:00:08,271 --> 00:00:11,186
梅花触头采用多点触碰式设计

6
00:00:11,186 --> 00:00:13,996
使得断路器的电弧能力得到显著提高

7
00:00:14,467 --> 00:00:16,552
在开关断路器的过程中

8
00:00:16,552 --> 00:00:18,967
触点间会产生放电现象

9
00:00:18,967 --> 00:00:21,653
由于梅花动触头的多点触碰式设计

10
00:00:21,653 --> 00:00:23,518
同时断开多个回路

11
00:00:23,518 --> 00:00:26,403
电弧的能量被分摊到各个触点上

12
00:00:26,403 --> 00:00:28,947
使得每个触点上的电弧能量减小

13
00:00:28,947 --> 00:00:31,212
动触头采用弧形设计

14
00:00:31,212 --> 00:00:33,877
让电场行成向外扩张的电场

15
00:00:33,877 --> 00:00:35,057
增加了横向力

16
00:00:35,067 --> 00:00:37,472
加上随着距离的越来越大

17
00:00:37,472 --> 00:00:40,867
使电弧在电压低于阈值时自行熄灭

18
00:00:40,867 --> 00:00:42,973
无需额外配置灭弧装置
