摘　　要：针对民用建筑供配电系统分级负荷的配电方式,重点分析研究低压母联自投功能与负荷卸载之间的配合关系,对传统卸载方式进行比较,提出"先投母联,再根据电流卸载"的优化解决方案,利用智能型空气断路器的电流卸载与恢复功能,根据变压器过负荷电流进行卸载,充分利用变压器的带载能力,改善非重要负荷的供电连续性。According to the distribution mode of grading load in power supply and distribution system of civil buildings, this paper focus on the analysis and research on the relations between low-voltage bus coupler automatic transfer and load shedding compared with traditional methods, proposing an optimized solution of ＂bus couple automatic transfer, then shedding load based on current＂. Meanwhile, the load shedding and reconnection of intelligent air circuit breakers can be used to shed load based on overload current of transformers. In addition, the load bearing capacity of transformers must be fully utilized to improve the continued power supply of non-critical load.
