摘要

本次设计的主要内容：照度计算、光源的初步选择、灯具选择和方案布置、供配电方案的确定、负荷计算、电气设备选型、电缆和导线的选择校验、变电所的初步设计、防雷与接地设计等。

照明设计采用利用系数法进行照度计算，确定光源数量、灯具选型以及布置，照明光源采用T5型荧光灯，并按照功率密度限值进行校验。高压侧由一路10KV市电埋地引入，低压侧采用380V/220V电源供电，采用混合式供电方式。需要系数法对建筑进行负荷计算，设置两台容量为125kVA的变压器，型号为SCB10，分别承担负荷为125.3kw、148.9kw。高低压侧均采用单母线不分段的接线方式，高压柜采用KZN1-12型开关柜，出线线缆采用JYV22线缆；低压柜采用GCK抽屉式开关柜，一般照明进线线缆采用YJV，应急照明进线线缆采用BTTZ。配电箱选用PZ30型号，切换箱选用XL21型号，配电箱断路器采用CM3塑壳断路器，照明回路断路器型号选择ch1小型断路器，插座回路断路器选择带漏电保护的ch1小型断路器。建筑按第三类防雷建筑标准进行防雷接地以及等电位方面的设计。
