电动机按钮联锁正反转控制电路的安装ppt课件

正反正反转控制控制线路路正反转控制线路按钮连锁的正反转控制线路利用按钮实现联锁控制，从而使两个接触器线圈不能同时得电，防止了主电路的短路事故请自行设计利用按钮互锁实现的正反转控制电路按钮连锁的正反转控制线路利用按钮实现联锁控制，从而使两个接触按钮联锁的正反转控制线路M3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮联锁正反转制线路图按钮联锁的正反转控制线路M3KM1KM2KM1KM1FRSM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图按下正转按钮SB2SB2常闭点断开M3KM1KM2KM1KM1FRSB1SB2L2L1L3QM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图KM1线圈得电M3KM1KM2KM1KM1FRSB1SB2L2L1L3QM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图KM1主触点闭合KM1常开辅助触点闭合自锁电机正转M3KM1KM2KM1KM1FRSB1SB2L2L1L3QM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图松开正转按钮SB2电机依然正传试想：若此时按下反转按钮SB3主电路会短路吗？为什么？试想：若此时按下反转按钮SB3能够直接实现反转吗？M3KM1KM2KM1KM1FRSB1SB2L2L1L3QM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图按下反转按钮SB3M3KM1KM2KM1KM1FRSB1SB2L2L1L3QM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图KM2线圈得电KM1自锁触点打开KM1主触点打开M3KM1KM2KM1KM1FRSB1SB2L2L1L3QM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图KM2线圈得电M3KM1KM2KM1KM1FRSB1SB2L2L1L3QM3KM1KM2KM1KM1FRSB1SB2L2L1L3QFFU1FU2SB3KM2KM2按钮连锁的正反转控制线路按钮联锁正反转制线路图电机反转KM2主触点闭合KM2常开辅助触点闭合自锁M3KM1KM2KM1KM1FRSB1SB2L2L1L3Q12按钮联锁正反转控制线路原理分析12按钮联锁正反转控制线路原理分析13正反转主电路接线图QSFU1KM1KM2FR13正反转主电路接线图QSFU1KM1KM2FR14按钮联锁正反转控制电路接线图FR10245672465714按钮联锁正反转控制电路接线图FR102456724657
