1
00:00:00,000 --> 00:00:01,386
当分闸时

2
00:00:01,386 --> 00:00:03,160
静动触头分离

3
00:00:03,160 --> 00:00:04,733
会形成电弧

4
00:00:04,733 --> 00:00:09,880
高真空环境有效抑制电子游离 触头特殊圆锤头设计

5
00:00:09,880 --> 00:00:11,140
让电弧发散

6
00:00:11,140 --> 00:00:11,790
喷射

7
00:00:11,790 --> 00:00:14,280
金属屏蔽罩凝结金属粒子

8
00:00:14,280 --> 00:00:16,160
让电弧很快熄灭
