曳引式电梯的节能改造分析

Improvement in the Energy Saving for the Traction Elevator

介绍了电梯曳引系统和控制系统的节能改造方案；分析了直流驱动系统、交流双速驱动系统和VVVF驱动系统的节能改造方式；探讨了可变速电梯技术、群控技术、超级电容技术、共直流母线技术等新技术在电梯节能方面的应用。对电梯节能改造过程中相关标准的符合性问题也作了探讨。

This paper introduces the plan of the energy saving modification of the traction system and control system, ana}yzes the ways of the energy saving modification about D.C.drive systemAC-2 drive system and VVVF drive system, and discusses the application of the variable-speed elevator technology, the group control technology, the super- capacitance technology and the D.C. bus technology to the energy saving. It also discusses the standards relating to the energy saving modification.
