摘要
节能,是当今社会的一大主题。电梯作为办公楼内的-耗能大户,其节能研究具有极大的意义。本文根据电梯的运行特性,结合变频器的结构,提出一种用于电梯的节能电路。该电路可以吸收电机反馈到变频器的再生电能;并且在电机需要能量时,可将之前存储的能量供给电梯使用,提高了电梯的能效性能。原理分析和仿真实验均验证了该电路的可行性。
Energy-saving is the main topic of nowadays. The power elevator consuming is one of the top power consumers of buildings. The paper proposes an energy-saving circuit used for elevator： The circuit can absorb the energy, which is feedback to the inverter by the elevator, and it can feed the deposited energy back to the elevator when the elevator needs energy. By this, it can increase the elevator energy performance. Principle analysis and simulation both verify the circuit feasibility.
