1、 Introduction

High voltage switchgear is a crucial equipment in the power system, which contains a large number of electrical connections, circuit breakers, and other key components inside. These components generate heat during operation and pose a risk of fire due to insulation aging, overload, or short circuit. Therefore, fire prevention and control of high-voltage switchgear is particularly important. The perfluorohexane automatic fire extinguishing system, as a new type of fire extinguishing technology, has shown great potential in fire prevention and control of high-voltage switchgear. This article will evaluate the fire control capability of the perfluorohexane automatic fire extinguishing system.

2、 Overview of Perfluorohexane Automatic Fire Extinguishing System

The Jiutong Changsheng Perfluorohexane Automatic Fire Extinguishing System has the functions of automatic fire detection, warning, and extinguishing, which is a new way of fire prevention and control for electrical equipment. The linear fire detector used in this system has strong flexibility and can be reasonably laid according to the internal structure of the high-voltage switchgear, achieving all-round and all-weather fire monitoring of the equipment. When the detector detects a fire, the fire extinguishing center analyzes the fire status data and automatically starts extinguishing when the preset conditions are met. Perfluorohexane fire extinguishing agent rapidly suppresses fires through three mechanisms: cooling, oxygen isolation, and blocking combustion reactions.

3、 Evaluation of Fire Control Capability of Perfluorohexane Automatic Fire Extinguishing System

Efficient fire extinguishing performance

Perfluorohexane fire extinguishing agent has demonstrated excellent performance in electrical fire extinguishing due to its high efficiency, cleanliness, and safety. It can quickly vaporize and absorb a large amount of heat in a very short period of time, effectively reducing the temperature of the fire scene, while isolating oxygen, achieving rapid fire extinguishing without leaving any residue. This is crucial for protecting precision electrical equipment from secondary damage.

Electrical insulation performance

Perfluorohexane has excellent electrical insulation properties and does not pose a risk of electric shock when extinguishing electrical fires, ensuring the safety of personnel and equipment during the firefighting process. This characteristic makes the perfluorohexane automatic fire extinguishing system particularly suitable for use in electrical equipment such as high-voltage switchgear.

Environmental characteristics

Perfluorohexane does not damage the atmospheric ozone layer, has a small impact on global greenhouse effect, and is an environmentally friendly fire extinguishing agent. The characteristic of no residue after use avoids secondary damage to the equipment and also conforms to modern environmental protection concepts.

intelligent control

The perfluorohexane automatic fire extinguishing system integrates advanced fire detection technology and intelligent control system. Capable of real-time monitoring of temperature, smoke and other parameters inside the distribution cabinet, and immediately initiating fire extinguishing procedures once abnormal situations are detected. This unmanned and intelligent management method not only improves fire extinguishing efficiency, but also reduces personnel safety risks.

Strong adaptability

The perfluorohexane automatic fire extinguishing system occupies a small space and is not limited by protective space. Using wear-resistant and flame-retardant materials to improve stability and enhance adaptability. In addition, the system can conduct detailed fire risk assessments based on actual needs, determine appropriate amounts of fire extinguishing agents and spraying methods.

4、 Testing process and results

In the high-voltage cabinet fire extinguishing test, we simulated various fire scenarios, including fires caused by insulation aging, overload, or short circuits. The test results show that the perfluorohexane automatic fire extinguishing system can detect fires and initiate fire extinguishing procedures in a very short period of time. The fire extinguishing agent quickly vaporizes and covers the entire fire scene, quickly suppressing the fire through three mechanisms: cooling, isolating oxygen, and blocking combustion reactions. During the testing process, the system did not experience any malfunctions or false alarms, demonstrating extremely high reliability and stability.

5、 Conclusion

The perfluorohexane automatic fire extinguishing system has demonstrated excellent fire control capabilities in the fire prevention and control of high-voltage switchgear. Its efficient fire extinguishing performance, electrical insulation performance, environmental protection characteristics, and intelligent control make this system an ideal choice for fire prevention and control of electrical equipment. Through this test, we further verified the reliability and stability of the perfluorohexane automatic fire extinguishing system independently developed by Shandong Zhongdao Fire Protection, providing strong guarantees for the safe and stable operation of the power system.
