计算机研究的结果是利用新的分析技术确定鼠笼式感应电机的各种运行量作为不平衡电压和机械负载的函数。其他地方也报道了一项关于单相极端不平衡的类似研究。然后将各种电机保护装置的操作特性叠加在电机操作曲线上,以评估特定继电器的有效性。这项研究的结果将有助于选择和设置继电器以提供电压不平衡保护,并可能为未来保护装置的开发提供工程原理。
The results are presented of a computer study to determine various operating quantities of squirrel-cage induction motors as a function of unbalanced voltage and mechanical loading utilizing a new analytical technique. A similar study with the extreme unbalance of single phasing was reported elsewhere. The operating characteristics of various motor protective devices are then superimposed on the motor operating curves to evaluate the effectiveness of the specific relay. The results of this study will aid in selecting and setting relays to provide protection against voltage unbalance and may possibly provide an engineering rationale for the development of future protective devices.
