摘要
在建筑施工现场,施工升降机操作频繁,且工作环境恶劣。分析了一些建筑施工现场所用的电气控制线路的安全性能,并对电气控制线路的设计进行了改进,在限位、短路、过载、断相及错相保护等方面增加了对设备的保护措施,提高了设备运行的安全可靠性和使用效率。
In construction site, the construction elevator was operated frequently and the working conditions were poor. The safety of some practical electricity circuits was analyzed concretely. By improving design of the electrical circuits, safety measures for equipment were added in position limitation, overload, short-circuit, phase failure and phase stagger, so that the safety and reliability of equipment are enhanced and the efficiency is increased.
