    Abstract When selecting ATSE in electrical design, utilization category should be considered according to the load in normal operation. Transfer type and transfer time should be selected according to load characteristic as well as the location of ATSE in the whole power supply and distribution system. The short?鄄circuit characteristic of ATSE should be considered separately based on PC，CC，CB class in case of short circuit.

    摘　要　提出电气设计中选择 ATSE 时，应按正常使用时的负荷情况考虑使用类别；根据负荷特性和 ATSE 在整个供配电系统中的位置选择转换类型及转换时间；在短路时按照 PC、CC、CB 级分别考虑其短路特性。
