    AbstractATSE is the key equipment to ensure the continuous power supply and reliable operation of important loads in power supply system of emergency power supply and standby power supply. Its breakdown or conversion failure will directly cause power failure of the loadresulting in personal injury or property loss and other serious consequences. When PC-level ATSE is installed in the power supply position it is necessary to focus on the matching degree of expected shortcircuit current and shortcircuit performance parameters and carefully analyze the coordination relationship between shortcircuit performance parameters and superior protection appliances of ATSE. Based on the analysis on shortcircuit connection and short time tolerance of PC - level ATSE installed at the power supply positionin this paperthe selection method and suggestions on shortcircuit performance parameters for PC - level ATSE are put forwardwhich has certain guiding significance for designers to correctly select powerlevel ATSE.

   摘 要:ATSE是应急电源、备用电源供电系统中确保重要负荷连续供电、可靠运行的关键设备,一旦损坏或转换失败将直接造成负载断电,导致人身伤害或财产损失等严重后果。当PCATSE安装在电源位置时,需要重点考虑预期短路电流与其短路性能参数的匹配程度,并仔细分析ATSE的短路性能参数和其上级保护电器的配合关系。针对设于电源位置的PCATSE的短路接通及短时耐受能力进行分析,提出针对PCATSE的短路性能参数的选择方法和建议,对设计师正确选用电源级ATSE有一定的指导意义。
