In recent years, as the advantages of perfluorohexanone automatic fire extinguishing device for rapid fire extinguishing and environmental protection have been recognized by the public, it has gradually been widely used in power distribution cabinets, electrical rooms and other equipment. This paper will introduce the application and working principle of perfluorohexanone automatic fire extinguishing device in the fire control of power distribution cabinets, and verify its fire extinguishing effect through experiments.
1. Introduction of perfluorohexanone automatic fire extinguishing device.
Perfluorohexanone automatic fire extinguishing device is an efficient and environmentally friendly fire extinguishing equipment, its working principle is mainly through the rapid vaporization of liquid perfluorohexanone at room temperature, absorbing a large amount of heat, reducing the temperature of the fire, and at the same time perfluorohexanone decomposes into inert gas at high temperature, thereby inhibiting flame combustion. The device has the advantages of fast fire extinguishing speed, no damage to the equipment, and a wide range of use, so it is of great significance in the fire protection of equipment such as power distribution cabinets.
Second, the working principle of perfluorohexanone automatic fire extinguishing device.
The working principle of perfluorohexanone automatic fire extinguishing device mainly includes three links: induction, alarm and fire extinguishing. First of all, the sensors in the device can monitor the temperature in the protective space such as the distribution cabinet in real time, and activate the alarm system as soon as an abnormal situation is detected. Secondly, the alarm system will send out an audible and visual alarm signal to prompt the staff to take measures in time. Finally, when the fire cannot be controlled, the device will automatically start the fire extinguishing program, and spray the perfluorohexanone liquid evenly inside the distribution cabinet through the nozzle, quickly reducing the fire temperature and inhibiting the flame combustion, so as to achieve the effect of rapid fire extinguishing.
3. Experimental verification of perfluorohexanone automatic fire extinguishing device.
In order to verify the extinguishing effect of the perfluorohexanone automatic fire extinguishing device, we conducted a set of experiments. In the experiment, we installed the device on the distribution cabinet and placed a certain amount of combustibles in the cabinet to simulate the fire scene inside the distribution cabinet. When the ignition source ignites the combustible, the perfluorohexanone automatic fire extinguishing device is quickly activated, and the fire is controlled within 3 seconds, effectively avoiding the expansion and spread of the fire. The experimental results show that the perfluorohexanone automatic fire extinguishing device has good fire extinguishing effect and practicability.
IV. Conclusions. In this paper, the application and working principle of perfluorohexanone automatic fire extinguishing device in the fire control of distribution cabinet are introduced, and its fire extinguishing effect is verified by experiments. The results show that the perfluorohexanone automatic fire extinguishing device has the advantages of rapid fire extinguishing, environmental protection and wide range of use, and is of great significance for the fire protection of distribution cabinets and other equipment. Therefore, in practical application, the use of perfluorohexanone automatic fire extinguishing device should be widely promoted to improve the safety and reliability of the equipment.
