摘要
提出了一种非反馈式的电梯节能方法:利用电梯系统自带的备用电池来吸收制动时产生的再生电能;吸收下来的电能用来实现断电自动平层,同时也可供风机、门机等设备使用。实验结果表明,在充电电流限定为8 A的情况下,该方法对再生电能的吸收率可达78%。
A non-feedback method for elevator energy saving was proposed.The regenerated power was absorbed using a battery set,and the battery set could be used for self levering when there was a sudden power failure.Experiments were carried out and results showed that about 80% of the regenerated power can be absorbed and the distance of self levering can be over 13 meters with the voltage of the battery decreased about 12 V.
