摘 要: | 介绍了一种电梯轿厢意外移动检测及控制回路,它利用再平层位置传感器的输出判断轿厢的运动。当检测到意外移动时,通过激活分励脱扣器的方式断开曳引电动机侧断路器,同时切断安全回路,曳引机的制动器抱闸,轿厢急停。若电梯再次运行需手动闭合断路器。

Abstract: | This paper introduces an elevator UCM detecting & control circuit, which uses the outputs from releveling position sensors, When UCM is found, the shunt release is activated and the breaker near the traction motor is tripped immediately. The safety circuit is cut off simultaneously. The brakes take action to stop the car. It needs to close the breaker manually the return to service of the elevator. |
