摘　　要：自动扶梯在酒店、商场、地铁、火车站、机场、写字楼、会馆等公共场所得到广泛使用,但由于其使用场所的特殊性,部分扶梯经常处于空载或高速运行状态,不仅浪费大量电能,还使扶梯部件产生不必要的磨损和疲劳损伤。针对这一问题,本文深入探讨自动手扶梯的节能降耗改造方法。首先分析传统自动手扶梯存在的问题,随后提出包括自动感应运行、Y—Δ转换运行和变频运行在内的三种节能改造方案,并详细阐述各方案的原理与特点。通过综合比较,最终选定变频运行模式作为前期改造试验方案。改造后的自动手扶梯不仅实现了显著的节能降耗效果,减少机械磨损,延长使用寿命,还提高了乘坐舒适性和安全性。因此,采用变频节能技术对自动手扶梯进行改造具有广阔的应用前景和社会效益。Escalators have been widely used in public places such as hotels,shopping malls,subways,railway stations,airports,office buildings,and halls,but due to the particularity of their use places,some escalators are often in a noload or high-speed running state,which not only wastes a lot of electrical energy,but also causes unnecessary wear and fatigue damage to the escalator components.In order to solve this problem,this paper deeply discusses the energy-saving and consumption-reducing transformation methods of escalators.This paper first analyzes the problems existing in the traditional escalator,and then proposes three energy-saving transformation schemes,including automatic induction operation,Y-δconversion operation and frequency conversion operation,and elaborates the principles and characteristics of each scheme.Through comprehensive comparison,the frequency conversion operation mode was finally selected as the preliminary transformation test plan.The transformed escalator not only achieves significant energy saving and consumption reduction,but also reduces mechanical wear,extends service life,and improves ride comfort and safety.Therefore,the use of frequency conversion energy-saving technology to transform the escalator has broad application prospects and social benefits.
