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
