- 1
- 00:00:00,000 --> 00:00:05,640
- 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
- 00:00:05,640 --> 00:00:07,253
- 都是真空而得名
- 3
- 00:00:07,253 --> 00:00:11,080
- 适用于频繁操作、灭弧不用检修的优点
- 4
- 00:00:11,080 --> 00:00:13,085
- 当断路器断开瞬间
- 5
- 00:00:13,085 --> 00:00:14,715
- 静动触头分离
- 6
- 00:00:14,715 --> 00:00:16,000
- 形成电弧
- 7
- 00:00:16,000 --> 00:00:18,773
- 高真空环境有效抑制电子游离
- 8
- 00:00:18,773 --> 00:00:22,048
- 触头锤头式加接触面波浪纹设计
- 9
- 00:00:22,048 --> 00:00:24,543
- 让电弧成多个爆炸式发散
- 10
- 00:00:24,543 --> 00:00:28,343
- 让金属快速横向向外层金属屏蔽层运动
- 11
- 00:00:28,346 --> 00:00:30,636
- 在屏蔽层快速凝结
- 12
- 00:00:30,636 --> 00:00:34,516
- 高真空环境下气体分子平均自由程变大
- 13
- 00:00:34,516 --> 00:00:36,236
- 碰撞游离概率低
- 14
- 00:00:36,240 --> 00:00:39,530
- 绝缘强度比常规气体高数十倍
- 15
- 00:00:39,530 --> 00:00:41,880
- 使介电强度迅速回复
- 16
- 00:00:41,880 --> 00:00:43,800
- 以及随着距离的增大
- 17
- 00:00:43,800 --> 00:00:49,386
- 从而让电流过零时 迅速切断电弧 且不会再次击穿
