有对重提升系统设备容量的修正计算

Revised Capacity Calculation of Elevating System with Balancing Weight

首先对有对重的提升系统进行了力学分析,得出了加速阶段由于惯性的作用电动机必须提供的附加力矩。然后讨论了加速阶段电动机的力矩、功率、转速的变化规律,在此基础上提出了上述电力拖动系统电气设备容量计算的修正方案。

Based on mechanics analysis of elevating system with balancing weight, the additional driving moment that the motor have to supply for accelerating a inertia load is obtained. Then the feature of moment, power, rotational speed according to the acceleration are discussed as the system is accelerated. And a scheme of revised calculation concerning the capacity of electrical installations for the elevating system is given.
