摘要
针对安全设施电源系统供电设计过程中存在的一味迎合规范字面意思,未能将电源、馈电导体、电缆管理系统等统筹考虑的情况,参照国内外标准,从安全设施电源供电持续时间、线路敷设及其安装构件的耐火性能等方面,对安全设施电源供电设计中的问题进行分析。
Seeing that electrical source for safety services power system blindly caters to the literal meaning in regulations and fails to take into full account power supply, feed-through and cable management system, this paper, in accordance with domestic and foreign standards, analyzes problems in electrical source design for safety services from the perspective of safety services electrical source, line laying and fire resistance of components.
