    Abstract:The classification, characteristics and load level in the school,and the operating characteristics of the electric equipment,such as air conditioning equipment,air source heat pump water heater and electric water boiler are analyzed,and the key points of distribution design are put forward;the load shall be calculated according to the school schedule;the selection of transformer capacity shall give consideration to both of the normal load and peak load;some suggestions on the indexes of transformer capacity in the school are provided according to the engineering experience;the measure to reduce the transformer capacity is put forward;it is recommended to investigate the building energy consumption and the indexes of transformer capacity in the school with the energy consumption monitoring system and big data.
    Key words:electric load;load classification;power distribution system;air conditioning unit;air source heat pump water heater;electric water boiler;indexes of transformer capacity;energy consumption monitoring system
 
    摘 要:分析学校用电负荷分类、特点、负荷等级;对空调设备、空气源热泵热水机组、电开水器等用电设备的运行特点进行分析,提出配电设计要点。提出按学校作息时间进行负荷计算;变压器容量选择要兼顾平时负荷和尖峰负荷,根据工程经验对学校变压器容量指标给出建议;提出减小变压器容量的措施,呼吁采用能耗监测系统、大数据对学校建筑能耗和变压器容量指标开展调查研究。
