The Transformation of Automatic Escalators and the Application of Frequency Conversion Energy-saving Technology
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 no-load 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-δ conversion 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.
