摘　　要：分析了某甲级体育馆负荷特点,设计了一种满足要求的供配电系统;针对场地照明的特点,设计了一种含备用电源的照明配电系统。对体育馆低压配电系统中的典型配电回路,计算了线路电压损失,验算了场地照明灯具的设备端电压偏差,满足规范要求;分析了配电线路各处短路电流,校核保护开关的分断能力、灵敏性和上下级选择性。By analyzing the electric load characteristics,the power supply and distribution system that meets the requirements of a Class A stadium was designed.According to the feature of field lighting,a lighting distribution system with backup power supply was designed.For the typical distribution circuit in the distribution system of the stadium,the voltage loss was calculated,and the voltage deviation of the equipment terminal of the field lighting was checked,which meets standard requirement.Meanwhile,the short-circuit currents in the distribution lines were analyzed,and the breaking capacity,sensitivity and upper-lower selectivity of the circuit breaker were checked.
