摘　　要：结合某建设项目,介绍防烟、排烟风机控制系统设计与安装。防烟、排烟风机控制方式分就近控制、消防联动控制、多线直接启停及风阀互锁。接近控制主要是依靠配电箱内KB0控制,控制与保护开关基本配置包含开关本体、电子过载脱扣器、短路报警触头、过载报警触头及辅助触头,其主回路和二次回路可实现消防风机就近控制;消防联动控制方式,应由同一报警区域内两只及以上独立的感烟火灾探测器或一只感烟探测器与一只手动火灾报警按钮的报警信号,作为加压送风口、排烟口开启和加压风机、排烟风机启动的联动触发信号,并应由消防联动控制器联动控制防烟、排烟风机的启动;防烟、排烟风机还应在消防控制室设置手动直接控制装置;排烟风机入口处的总管上设置的280℃排烟防火阀在关闭后应直接联动控制风机停止,排烟防火阀及风机的动作信号应反馈至消防联动控制器。Combined with a construction project,the design and installation of smoke prevention and exhaust fan control system are introduced.The control methods for smoke prevention and exhaust fans are divided into nearby control,fire linkage control,multi line direct start stop,and air valve interlocking.Proximity control mainly relies on KB0 control inside the distribution box.The basic configuration of the control and protection switch includes the switch body,electronic overload release,short circuit alarm contact,overload alarm contact,and auxiliary contact.Its main circuit and secondary circuit can achieve nearby control of the fire fan.The fire linkage control method should use the alarm signals of two or more independent smoke detectors or one smoke detector and one manual fire alarm button in the same alarm area as the linkage trigger signals for the opening of the pressurized air supply outlet and smoke exhaust outlet,as well as the start of the pressurized fan and smoke exhaust fan.The fire linkage controller also control the start of the smoke control and smoke exhaust fan through linkage.Smoke prevention and exhaust fans also are equipped with manual direct control devices in the fire control room.The 280℃smoke exhaust fire damper set on the main pipe at the entrance of the smoke exhaust fan are directly linked to control the fan to stop after being closed.The action signals of the smoke exhaust fire damper and fan are fed back to the fire linkage controller.
