- 1
- 00:00:00,000 --> 00:00:02,680
- 真空断路器机械联动特性
- 2
- 00:00:02,680 --> 00:00:08,133
- 储能机械:外部直流屏电源直流+220V经柜顶小母线
- 3
- 00:00:08,134 --> 00:00:12,094
- 到达低压室QF2 开关下因到端子排
- 4
- 00:00:12,094 --> 00:00:15,174
- 端子排到达转换开关航空插头
- 5
- 00:00:15,174 --> 00:00:18,174
- 到储能开关限位开关常闭点
- 6
- 00:00:18,174 --> 00:00:20,840
- 到直流储能电机+端子
- 7
- 00:00:20,841 --> 00:00:25,271
- 后经直流电机负端子到达储能限位开关常闭点后
- 8
- 00:00:25,271 --> 00:00:27,311
- 经航空插头出回到端子排
- 9
- 00:00:27,868 --> 00:00:30,534
- 后回到开关到柜顶小母线
- 10
- 00:00:30,534 --> 00:00:34,374
- 这样可手动或自动接通未储能电机让其转动
- 11
- 00:00:34,374 --> 00:00:36,384
- 经链条带动曲轴旋转
- 12
- 00:00:36,388 --> 00:00:39,241
- 带动合闸储能弹簧拉伸储能
- 13
- 00:00:39,242 --> 00:00:43,602
- 合闸机械 按动合闸按钮让合闸电磁铁吸合
- 14
- 00:00:43,602 --> 00:00:47,575
- 铁芯推动卡簧 或者手动按动合闸按钮
- 15
- 00:00:47,576 --> 00:00:50,949
- 推动卡簧 让合闸储能弹簧释放
- 16
- 00:00:50,949 --> 00:00:52,669
- 带动主轴旋转
- 17
- 00:00:52,669 --> 00:00:56,849
- 主轴后面有杠杆推动真空断路器动触头向上运动
- 18
- 00:00:56,849 --> 00:00:57,989
- 动静触头结合
- 19
- 00:00:58,550 --> 00:00:59,600
- 分闸机械
- 20
- 00:00:59,600 --> 00:01:00,650
- 在合闸时
- 21
- 00:01:00,650 --> 00:01:03,640
- 主轴运动带动三个分闸储能弹簧拉伸
- 22
- 00:01:04,190 --> 00:01:09,590
- 分闸弹簧已经储能 让按动分闸按钮让分闸电磁铁吸合
- 23
- 00:01:09,590 --> 00:01:13,630
- 铁芯推动卡簧释放 在分闸弹簧的能量下
- 24
- 00:01:13,630 --> 00:01:15,970
- 主轴旋转拉伸后面的连杆
