摘　　要：随着电梯使用率越来越高,对电梯的电气安全也提出更高要求。介绍了电梯轿厢由于意外移动产生的危害并阐述了轿厢意外移动产生的原因。为防止轿厢意外移动GB7588-2003第1号修改单中要求新制造的电梯必须增设轿厢意外移动(UCMP),但符合一定条件可不装设该功能。目前轿厢意外移动(UCMP)功能由检测子系统、自监测子系统和制停子系统相互组合构成,通过检验案例分析了轿厢存在贯通门情况下在安装轿厢意外移动装置时将贯通门侧的装置遗漏的情况,提出了改进的方法。With the increasing use rate of elevators,higher requirements are put forward for the electrical safety of elevators.The hazards caused by the accidental movement of elevator car were introduced and the reasons for the accidental movement of elevator car was expounded.In order to prevent the car from moving accidentally, it is required in GB7588-2003 amendment No.1 that UCMP must be added to the newly manufactured elevator,but it can not be installed if it meets certain conditions.At present, the UCMP function is composed of detection subsystem, self-monitoring subsystem and stop subsystem. Through the case study, the situation that the device on the side of the through door was analyzed, and the improved method was put forward.
