音速超细干粉灭火装置根据驱动方式和结构形式可分为多种类型，主要包括贮压式和非贮压式两大类。贮压悬挂式超细干粉自动灭火装置通过贮压方式驱动超细干粉灭火剂，结构包括灭火剂储瓶、感温释放组件及喷头，采用悬挂式安装，无需管道系统。火灾发生时，温度触发或电启动释放灭火剂，适用于相对封闭或敞开式空间的局部灭火。该装置使用ABC超细干粉灭火剂，覆盖固体、液体、气体（可切断气源）及电气火灾。贮压悬挂式装置还配备压力表用于监测贮压状态。
The supersonic ultra-fine dry powder fire extinguishing device can be divided into various types according to the driving mode and structural form, mainly including two categories: storage pressure and non storage pressure. The pressure storage suspended ultra-fine dry powder automatic fire extinguishing device drives the ultra-fine dry powder fire extinguishing agent through pressure storage. The structure includes a fire extinguishing agent storage bottle, a temperature sensing release component, and a nozzle. It is installed in a suspended manner and does not require a pipeline system. When a fire occurs, temperature triggers or electrically activates the release of fire extinguishing agents, suitable for local fire extinguishing in relatively enclosed or open spaces. This device uses ABC ultra-fine dry powder fire extinguishing agent to cover solid, liquid, gas (can cut off gas source) and electrical fires. The storage pressure suspension device is also equipped with a pressure gauge to monitor the storage pressure status.
非贮压式装置则通过燃气发生器等手段在火灾发生时现场产生驱动气体，推动干粉喷射。固定式燃气型超音速干粉灭火系统由探测系统、控制系统和超音速干粉灭火装置组成。控制接口接收来自控制器或手动紧急启动按钮的信号，输出序列脉冲顺次启动灭火装置，宜采用具有智能检测功能的控制接口。
Non pressure storage devices use gas generators and other means to generate driving gas at the scene during a fire, which drives the injection of dry powder. The fixed gas type supersonic dry powder fire extinguishing system consists of a detection system, a control system, and a supersonic dry powder fire extinguishing device. The control interface receives signals from the controller or manual emergency start button, and outputs sequence pulses to sequentially start the fire extinguishing device. It is recommended to use a control interface with intelligent detection function.
在适用范围方面，音速超细干粉灭火装置可扑救A类火灾（如棉、木、麻、纸、橡胶、塑料、烟草等可燃固体火灾）、B类火灾（如原油、柴油、汽油、有机溶剂等可燃液体和可熔化固体火灾）。固定式燃气型超音速干粉灭火系统还可用于灭火前可切断气源的气体火灾以及带电设备火灾。但不适用于硝化纤维、炸药等无空气仍能迅速氧化的化学物质与强氧化剂的火灾，以及钾、钠、镁、钛、锆等活泼金属及其氢化物的火灾。
In terms of applicability, the sonic ultra-fine dry powder fire extinguishing device can extinguish Class A fires (such as combustible solid fires of cotton, wood, hemp, paper, rubber, plastic, tobacco, etc.) and Class B fires (such as combustible liquid and meltable solid fires of crude oil, diesel, gasoline, organic solvents, etc.). The fixed gas type supersonic dry powder fire extinguishing system can also be used for gas fires where the gas source can be cut off before extinguishing, as well as fires involving live equipment. But it is not applicable to fires caused by chemical substances and strong oxidants that can rapidly oxidize without air, such as nitrocellulose and explosives, as well as fires caused by active metals and their hydrides such as potassium, sodium, magnesium, titanium, zirconium, etc.
典型应用场所包括配电柜、电缆沟、电子计算机房等相对封闭空间。装置可单独使用保护小型空间，或联合使用覆盖更大区域。超细干粉灭火装置还广泛应用于风力发电机舱、铁路隧道、综合管廊、变电站及城市地下综合管廊等场所。贮压式装置尤其适用于电缆隧道、配电柜等场所，非贮压式装置多用于汽车发动机舱等小空间。贮压悬挂式超细干粉自动灭火装置的全淹没保护体积可达126立方米，局部淹没保护面积可达15平方米。
Typical application locations include relatively enclosed spaces such as distribution cabinets, cable trenches, and electronic computer rooms. The device can be used alone to protect small spaces or in combination to cover larger areas. The ultra-fine dry powder fire extinguishing device is also widely used in places such as wind turbine cabins, railway tunnels, comprehensive pipe galleries, substations, and urban underground comprehensive pipe galleries. Pressure storage devices are particularly suitable for places such as cable tunnels and distribution cabinets, while non pressure storage devices are often used in small spaces such as car engine compartments. The total submerged protection volume of the pressure storage hanging ultra-fine dry powder automatic fire extinguishing device can reach 126 cubic meters, and the local submerged protection area can reach 15 square meters.
