摘要
根据《高层民用建筑设计防火规范》(GB50045-95,2005年版)和《建筑设计防火规范》(GB50016-2006)要求,分析了电气火灾监控系统的设计要求、监控器的设置位置、保护分级设置等问题,并就电气火灾监控系统设计中配电线路漏电报警、配电线路和设备的温度报警以及中性线断线报警的设置进行了阐述。提出电气火灾监控系统的设计应以线路漏电检测和报警为主,可根据负荷特性和运行状况,在配电设备和线路的适当部位(如变压器、电气竖井内的电缆桥架和电缆夹层等)增加温度监控器。
According to the demands of code for fire protection design of tall buildings GB 50045-95 and code of design on building fire protection and prevention GB 50016-2006, the article analyzes the requirements of the design on alarm and control system for electric fire prevention, the detector setting, and the prevention classification setting. And the article describes the leakage alarm of distribution line, the temperature alarm of distribution line equipment and the setting of neutral conductor broken alarm in the deign. The author concludes that the distribution line leakage test must be emphasized in the design of electrical fire control system. And based on the characteristic and operation status of the load, temperature detector can be added in the proper place of distribution line and equipment, such as transformer, cable tray and cable interlayer in the electric silo, etc.
