第一节临时施工用电
一、设计依据
设计依据主要包括以下规程规范及资料:
(1)《建筑工程施工现场供用电安全规范》GB50194—93;
(2)《施工现场临时用电安全技术规范》JGJ46—2005;
(3)《低压配电设计规范》GB50054—95;
(4)《供配电系统设计规范》GB50052—95;
(5)《通用用电设备配电设计规范》GB50055—93;
(6)甲方提供的现场电源资料;
(7)现场临时用电设备负荷和配置资料;
二、概况
本工程现场临时用电系统,根据JGJ46-88临时用电规范而设计。根据表内临时用电设备负荷统计,,计算容量256KVA。(将视在负荷换算到有功负荷,,。)甲方宜提供320千瓦,方可满足施工用电要求;另自备120KW柴油发电机一台;为确保施工用电可靠,合理节约能源。在供电结构上合理安排。加强管理。
