- 1
- 00:00:00,000 --> 00:00:05,590
- VS1真空断路器因其灭弧介质和灭弧后触头间隙的绝缘介质
- 2
- 00:00:05,590 --> 00:00:07,160
- 都是真空而得名
- 3
- 00:00:07,160 --> 00:00:10,480
- 适用于频繁操作、灭弧不用检修
- 4
- 00:00:10,480 --> 00:00:12,455
- 当断路器断开瞬间
- 5
- 00:00:12,455 --> 00:00:14,065
- 静动触头分离
- 6
- 00:00:14,065 --> 00:00:15,330
- 形成电弧
- 7
- 00:00:15,330 --> 00:00:18,066
- 高真空环境有效抑制电子游离
- 8
- 00:00:18,066 --> 00:00:21,281
- 触头锤头式加接触面波浪纹设计
- 9
- 00:00:21,281 --> 00:00:23,706
- 让电弧成多个爆炸式发散
- 10
- 00:00:23,706 --> 00:00:25,201
- 在电场的干扰下
- 11
- 00:00:25,213 --> 00:00:29,163
- 让金属快速横向向外层金属屏蔽层运动
- 12
- 00:00:29,163 --> 00:00:31,383
- 在屏蔽层快速凝结
- 13
- 00:00:31,383 --> 00:00:34,958
- 高真空环境下气体分子平均自由程变大
- 14
- 00:00:34,960 --> 00:00:36,835
- 碰撞游离概率低
- 15
- 00:00:36,835 --> 00:00:40,030
- 绝缘强度比常规气体高数十倍
- 16
- 00:00:40,030 --> 00:00:42,200
- 使介电强度迅速回复
- 17
- 00:00:42,200 --> 00:00:44,360
- 以及随着距离的增大
- 18
- 00:00:44,360 --> 00:00:46,405
- 从而让电流过零时
- 19
- 00:00:46,405 --> 00:00:48,035
- 迅速切断电弧
- 20
- 00:00:48,035 --> 00:00:49,773
- 且不会再次击穿
