建筑消防电气线路设计浅析
一、摘要:火灾事故的发生,不仅威胁人们的人身和财产安全,而且造成极大的经济损失;随着近年国内经济的发展、第三产业的兴起、智能建筑的增多以及装修工程的普及,火灾隐患也随之增多。据统计,在诸多引起火灾的因素中,以电气线路引起火灾的比例为最高。建筑内电气火灾的起因可能是用电设备出现故障,而大多数则是电线因短路或绝缘受损或老化。
为了能够尽早地发现火灾,有效地扑救,保证人员能顺利地疏散,就必须保证消防系统在火灾发生时能够正常供电,要求消防系统的线路要十分可靠。
本文简要分析了一般电力线路和消防设备配电线路的选型、敷设、防火设计与性能要求。

Abstract: The fire accident, not only threatens the safety of people's life and property, but also cause great economic loss; in recent years with the development of domestic economy, the tertiary industry, the emergence of intelligent building and decoration increasing popularity, fire hazards are increasing. According to statistics, factors causing fire in many, the electrical circuit caused the fire was most. The cause of electrical fire in buildings may be the use of electrical equipment failure, and most are wire for short circuit or insulation is damaged or aging.
In order to early detection of fires, effectively saves, assurance personnel can essfully evacuated, it must ensure that fire system can normal power supply in case of fire, fire system line to be very reliable.
This paper analyzes the general requirements of power lines and fire fighting equipment type selection of distribution line, laying, fire protection design and performance.
Key words: construction; lines; fire protection design
