自动扶梯是目前大型商场、超市、机场、地铁、宾馆等公共场合使用量较大的交通工具,以前安装的自动扶梯由于技术、资金等原因,大多采用普通的直接起动或降压起动控制方式,扶梯起动后无论是否有乘客乘坐始终保持匀速运行,存在耗电量较大、故障率高、使用成本高等弊端,综合经济效益较差,结合当今世界提倡的节能、环保、低碳生活方式以及提高自动扶梯的经济效益的现实需求,浅谈自动扶梯节能改造的几种控制方案。 Escalator is a large amount of vehicles used in public places such as large shopping malls, supermarkets, airports, subways, hotels, etc. Most of the previously installed escalators use ordinary direct-start or step-down starting control methods due to technical and financial reasons. After the escalator is started, whether or not there are passengers who ride at all times and maintain constant speed operation, there are disadvantages such as large power consumption, high failure rate, high cost of use, poor overall economic efficiency, combined with energy saving, environmental protection, low-carbon lifestyle and improvement advocated in the world today. The actual needs of the economic benefits of escalators, a brief discussion on several control schemes for energy-saving renovation of escalators.
