摘要
民用建筑中电气火灾大多是由于电气线路的原因引起的。指出根据配变电系统、配电方式、用电负荷的等级和环境特征,采取一些措施以保证电气线路运行安全、可靠。应正确地选择电缆、电线、母线槽及电缆桥架,做好配电线路敷设的防火蔓延,处理好层间及防火分区耐火墙贯通部分的防火隔离密封,选择适当的配电线路的电气防火保护。
The electrical fires are mostly caused by the electrical wiring. Based on distribution substation system, distribution way, power load level and environmental features, this paper took some measures to ensure the safe and reliable operation. The cable wire, bus duct and cable bridge were correctly choosed. The fire spread laying of distribution line was completed. The fire isolation seal, of the layers and fire-resistant wall cut-through pars in fire compartment, were handled. The electrical fire protection of distribution line was selected correctly.
