在GB 7588—2003《电梯制造与安装安全规范》中.对电气安全回路的控制功能要求为直接作用在控制电梯驱动主机供电的设备上。任一个电气安全装置的动作应防止电梯驱动主机启动,或使其立即停止运转。但是在某些电梯设计中,存在着违反安全规范的设计。2007年12月,在整机验收某单位的l台载货电梯时,在检验中发现空载电梯正常运行。此时打开层门,电梯轿厢滑行至少350mm。
In GB 7588-2003 “Elevator manufacturing and installation of safety norms.” The control function of the electrical safety circuit requirements for the direct role in the control of the elevator drive host power supply equipment. The operation of any electrical safety device shall prevent the elevator-driven main engine from starting or stopping it immediately. However, in some elevator designs, there is a design that violates safety regulations. December 2007, the unit acceptance of a unit l lifts, the inspection found no-load elevator normal operation.
