建筑电气防火设计中电线电缆的应用技术

The Application Technology of Wire and Cable in Building Electrical Fire Protection Design

依据中国消防网统计数据,2016年,全国共接报火灾31.2万起,伤1 065人,亡1 582人,直接财产损失达37.2亿元,其中,违反电气安装使用规定引起的火灾占总量的30.4%,电气火灾已成为主要的火灾形式。建立电气系统的关键与基础是做好电气防火设计,电线电缆又在电气防火设计中占据着主要地位,完善处理电线电缆有助于提高整体建筑的电气防火性能。因此,阐述电线电缆的选用原则,分析电缆的铺设对策以及在建筑电气防火设计中电线电缆涉及的主要应用技术,力求提升供配电系统的可靠性与安全性,完成全方位的电气防火设计,避免火灾的出现。

According to the statistical study of China fire network,312 thousand fires were reported in China,1 065 people were injured,1 582 people were killed ,and 3 billion 720 million yuan was lost in the direct property in 2016.During this data,Because of the 30.4% of the total amount of fire caused by the violation of the regulations of electrical installation and use,so the electric fire was the main factor causing the fire.The key and foundation of the building electrical system is the fire protection design. Wire and cable occupy the main position in the fire protection design,so the accurate use of wire and cable helps to improve the electrical fireproof performance of the whole building.The article mainly analyzes and expounds the selection of wire and cable,the countermeasures of laying cable and the application technology of wire and cable in the design of building electrical fire protection.The purpose is to improve the reliability and safety of the power supply and distribution system,to achieve a full range of electrical fire protection design,and to avoid the occurrence of fire.
