Abstract：In this paper,considering the different protection requirements for distribution lines supplying power to important sites including the ICU and non‑important sites including the general consulting room in medical buildings and based on product manufacturing standards,the requirements for selective coordination of circuit breakers subject to different product manufacturing standards for protecting lines in medical buildings in different application scenarios are analyzed.

Key words：medical building;ICU;general consulting room;protection of distribution line;circuit breaker;tripping characteristics;selective coordination;short‑circuit instantaneous protection

摘　要：针对医疗建筑中ICU等重要场所和普通诊室等非重要场所供电的配电线路保护要求的不同，结合产品制造标准，分析在满足不同产品制造标准断路器应用场景下对医疗建筑线路保护的选择性要求。

关键词：医疗建筑；ICU；普通诊室；配电线路保护；断路器；脱扣特性；选择性配合；短路瞬动保护
