(图1) 连锁继电器手柄在跳闸位置时(回路没有异常)。 FC接点和LR接点都处在断开状态。 (图2) 用手动把手柄旋转到复位的位置时(正常位置,回路没有异常)。 开关被机械方式锁定,不能用手动让其跳闸。 此时LR接点接通,FC接点继续断开。 (图3) 当回路发生异常情况即FC接点接通时,如果通过LR接点供给线圈瞬间电压,手柄将自动回到剧} 位置,LR接点断开。 因线圈上没有持续电压的施加,所以防止线圈的过热现象,此时如果把手柄旋转到复位位置, 么由于通过FC和LR接点给线圈施加电压,因此放开手柄手柄就自动回到跳闸位置,即因外部回 异常而闭合的接点FC不断开的情况下手柄不可能回到复位的位置,如果排除回路故障Fc}妾点断 手柄就可回到图1的状态。 (Fig.1)When the handle of Lockout Relay is in the "TRIP" position(circuit is normal), both "FC" contact and "LR" contact are separated. (Fig. 2)Since switch stops mechanicallyf handle is manual operated turned"RESETI position(circuit is normal), cannot “TRIP" manually. 1n this case, "LR" contact sticks, "FC" contact is continually separated. (Fig.3) When circuit is abnormal state, that is when "FC" contact sticks,if moment voltage is supplied fo coil through "LR" contact, handle becomes "TRIP'I position automatically and "LR" contact is separated. Accordingly, because continuous voltage supply fO coil is not occurred overheating Of coil is avoided. Here,if handle Of switch is turned to "RESET" position manually, since voltage is supplied lO coil through "FC”&”LR" contacts, handle again returns lO"TRIP" position when hand released. That js,unless contact "FC" is separated by abnormal state of external circuit, handle can't return fo “RESET" position.Jf abnormal circuit is corrected, contact "FC" is separated and returns fo(Fig.l) state again.
