高层民用建筑漏电火灾报警系统应用的探讨

Discussion on Current-leakage Monitoring and Fire Alarming System Applied to Tall Civil Buildings

《高层民用建筑设计防火规范》对电气防火提出了更高的要求,参考施耐德及其它公司的产品提出漏电火灾报警系统的解决方案:①漏电电流信号的检出可采用:800￣4000A Masterpact MT框架型断路器装Micrologic控制单元的数字屏LCD、配通信选件(COM)和Micrologic控制电元;在Compact NS100￣NS630断路器上装Vigi漏电模块;VigiCompact NS一体化漏电塑壳断路器配SDV辅助开关既报警又跳闸;VigiCompactNSD100、NSD160、NSD250一体化结构断路器通过SDV输出报警信号只报警不跳闸;Vigirex漏电剩余电流继电器。②漏电报警信号的采集:采用施耐德电气公司的Powerlogic配电监控系统和现场总线系统(FCS)。

Higher requirements of electric fire protection are mentioned in code for fire protection design of tall building. The paper gives a currentleakage monitoring and alarming system referenced Schneider Electric products. This approach can achieves following function： picking up current-leakage signal adopt 800-4 000A Masterpact MT moulded case circuit-breaker with Micrologic control unit, LCD, COM unit; Vigi current-leakage module mounted on Compact NS100-NS630 circuit-breaker, VigiCompact NS with SDV auxiliary contact can alarm and trip power off; but VigiCompactNSD100, NSD160, NSD250 can only alarm, not trip. Current-leakage alarming signal can be sampled by Powerlogic monitoring system and field bus system.
