- 1
- 00:00:00,000 --> 00:00:03,180
- 220断路器燃弧熄弧特性分闸时
- 2
- 00:00:03,180 --> 00:00:05,550
- 动触头和静触头是插接的
- 3
- 00:00:05,550 --> 00:00:07,866
- 动喷嘴和静喷嘴是插接的
- 4
- 00:00:07,866 --> 00:00:11,246
- 动气缸和静气缸上下端是正好对接的
- 5
- 00:00:11,246 --> 00:00:13,486
- 当动触头分离往下走时
- 6
- 00:00:13,486 --> 00:00:15,436
- 气缸随同一起往下走
- 7
- 00:00:15,440 --> 00:00:18,270
- 并压缩气缸里的六氟化硫气体
- 8
- 00:00:18,270 --> 00:00:18,920
- 使得
- 9
- 00:00:18,920 --> 00:00:20,300
- 气体压力剧增
- 10
- 00:00:20,300 --> 00:00:22,573
- 当动静触头刚好分开时
- 11
- 00:00:22,573 --> 00:00:24,563
- 动静喷嘴恰好分离
- 12
- 00:00:24,563 --> 00:00:28,233
- 这样气缸里的高压六氟化硫气体恰恰吹出
- 13
- 00:00:28,240 --> 00:00:30,140
- 将产生的电弧吹散
- 14
- 00:00:30,140 --> 00:00:32,980
- 同时六氟化硫具有高负性特性
- 15
- 00:00:32,980 --> 00:00:34,760
- 会吸引负电荷电子
- 16
- 00:00:34,760 --> 00:00:36,120
- 让负离子过高
- 17
- 00:00:36,120 --> 00:00:38,360
- 使电子迁移率大大降低
- 18
- 00:00:38,360 --> 00:00:40,560
- 进一步加速了电弧的熄灭
