技术领域Technical field

When the fire is detected, there is a long fire fermentation time from the prompt to the staff putting out the fire, which greatly increases the scope and scope of the fire. The severity also increases the risk for workers when putting out fires, and cannot reduce the damage to electrical equipment. On the other hand, the fire extinguishing effect of fire extinguishers at different temperatures is also unstable, so the fire extinguishing effect and stability of fire extinguishers cannot be guaranteed. , thus easily causing the fire to re-ignite due to insufficient fire extinguishers, further increasing property losses and safety hazards caused by fires in electrical equipment.

再次需要说明的是,灭火装置为防复燃灭火材料,防复燃灭火材料的核心原料是全氟己酮,并以固体形态应用。全氟己酮在常温常压下是液体状态,一般以浸没的方式作用在电气设备内部,使用时需要专用容器和复杂的系统设备,需要占用一定的专用空间,只有符合相应空间要求的场景才能使用,具有一定的局限。It should be noted again that the fire extinguishing device is an anti-reignition fire-extinguishing material. The core raw material of the anti-reignition fire-extinguishing material is perfluorohexanone, which is applied in solid form. Perfluorohexanone is in a liquid state at normal temperature and pressure, and generally acts inside electrical equipment by immersion. Its use requires special containers and complex system equipment, and requires a certain amount of dedicated space. It can only be used in scenarios that meet the corresponding space requirements. Use has certain limitations.

It fills the gap in unattended small space fire extinguishing means. At the same time, it also solves the problem that other fire protection products can only protect large spaces.

A2、将各测试组中的点火装置按照相同火势和相同时刻点燃各测试组中的电气设备,当各测试组中灭火装置检测到失火时,启动灭火,以启动灭火时刻作为开始采集时刻,进而按照预设时间间隔,布设各采集时间点,由此采集电气设备在各采集时间点对应的温度,并在灭火结束时自动关闭灭火,并在灭火测试结束后获取各测试组中灭火装置对应的响应速度、灭火时长、灭火材料消耗量,以此完成各测试组中电气设备的灭火测试。A2. The ignition devices in each test group ignite the electrical equipment in each test group according to the same fire intensity and the same time. When the fire extinguishing device in each test group detects a fire, fire extinguishing is started, and the fire extinguishing time is used as the starting collection time, and then Set up each collection time point according to the preset time interval, thereby collecting the temperature corresponding to the electrical equipment at each collection time point, and automatically turn off the fire extinguishing when the fire extinguishing is completed, and obtain the corresponding temperature of the fire extinguishing device in each test group after the fire extinguishing test is completed. Response speed, fire extinguishing time, and fire extinguishing material consumption are used to complete the fire extinguishing test of electrical equipment in each test group.

需要说明的是,各测试箱中安装有温度传感器,当各测试箱中温度传感器采集的温度大于设定的高温阈值时,开启各测试组中的灭火装置,同时当各测试箱中温度传感器采集的温度小于设定的低温阈值时,关闭各测试组中的灭火装置;It should be noted that a temperature sensor is installed in each test box. When the temperature collected by the temperature sensor in each test box is greater than the set high temperature threshold, the fire extinguishing device in each test group is turned on. At the same time, when the temperature sensor in each test box collects When the temperature is lower than the set low temperature threshold, turn off the fire extinguishing devices in each test group;

上述中,所述灭火信息包括响应速度、灭火材料消耗量、电气设备在各采集时间点对应的温度;Among the above, the fire extinguishing information includes response speed, fire extinguishing material consumption, and the corresponding temperature of the electrical equipment at each collection time point;

环境信息包括环境温度、烟雾浓度、噪音响度、污染性气体浓度。Environmental information includes ambient temperature, smoke concentration, noise loudness, and pollutant gas concentration.

还需要说明的是,各测试组的电气设备均安装有温度传感器,通过温度传感器采集各测试组中电气设备在各采集时间点对应的温度,在灭火测试结束后从灭火装置控制中心获取各测试组中灭火装置对应的响应速度、灭火时长、灭火材料消耗量;各测试组对应的测试箱中安装有温度传感器、烟雾传感器、噪声传感器、气体传感器,通过温度传感器、烟雾传感器、噪声传感器、气体传感器分别采集各测试组在各监测时间点对应的环境温度、烟雾浓度、噪音响度、污染性气体浓度;各测试箱的上方安装有摄像头,通过摄像头采集各测试组中电气设备的图像,作为各测试组对应的设备图像。It should also be noted that the electrical equipment in each test group is equipped with temperature sensors. The temperature corresponding to the electrical equipment in each test group at each collection time point is collected through the temperature sensor. After the fire extinguishing test is completed, each test is obtained from the fire extinguishing device control center.

再次需要说明的是,当灭火装置开启后,灭火装置瞬间释放全氟己酮,全氟己酮会与空气形成混合气体,混合气体会吸收充足的热量以破坏燃烧四面体平衡,导致燃烧区快速冷却下来,并降低到火焰熄灭的温度点,因此对各测试组中电气设备在各采集时间点的温度进行采集,清楚的展示了燃烧区域的温度变化;当电气设备复燃时,环境温度升高、烟雾浓度上升或者电气设备发出噪音、爆炸声或弧光声等异常声音,因此需要对各测试组在各监测时间点对应的环境温度、烟雾浓度、噪音响度进行采集;It should be noted again that when the fire extinguishing device is turned on, the fire extinguishing device instantly releases perfluorohexanone. Perfluorohexanone will form a mixed gas with air. The mixed gas will absorb sufficient heat to destroy the combustion tetrahedral balance, causing the combustion zone to rapidly Cool down and reduce to the temperature point where the flame goes out. Therefore, the temperature of the electrical equipment in each test group at each collection time point is collected, which clearly shows the temperature changes in the combustion area; when the electrical equipment re-ignites, the ambient temperature rises. High, smoke concentration rises, or electrical equipment emits abnormal sounds such as noise, explosion sound or arc sound. Therefore, it is necessary to collect the ambient temperature, smoke concentration, and noise loudness corresponding to each test group at each monitoring time point;

What is especially important is that it is very close to the protected area and can effectively extinguish the fire source instantly and extinguish the fire source. In the initial stage, to minimize the loss of fire, installing the fire extinguishing device inside the electrical equipment can effectively extinguish the fire source instantly and reduce the damage to the electrical equipment.
