In mining operations, electrical cabinets, switch cabinets, distribution boxes and other electrical equipment are the core devices that ensure power supply and distribution. Whether it is surface beneficiation plants, lifting machine rooms, or mining workfaces and substations in complex underground environments, electrical cabinets shoulder important missions. However, the complexity of the mining environment poses many fire hazards to electrical cabinets. Once a fire occurs, it can not only cause serious equipment damage, interrupt production, but may even endanger personnel safety. Therefore, customized automatic fire extinguishing systems - electrical cabinet automatic fire extinguishing devices have become the key to fire prevention in mining power system equipment.

In response to the fire risk of mining electrical cabinets, customized solutions for automatic fire extinguishing systems for electrical cabinets have emerged. This plan combines the actual environmental characteristics of the mine, adopts advanced fire extinguishing technology and intelligent control methods, and provides comprehensive and efficient fire protection for electrical cabinets.

1. Intelligent detection and warning system

1) High precision sensors: Install high-precision temperature and flame detectors inside the electrical cabinet to monitor real-time fire signals such as temperature and flame inside the cabinet.

2) Intelligent algorithm analysis: By analyzing and processing the data collected by sensors through intelligent algorithms, once abnormal situations are detected, the warning mechanism is immediately triggered.

3) Diversified warning methods: using various methods such as sound and light alarms, remote monitoring terminals, etc. to issue alerts to operators and remind them to take timely response measures.

2. Efficient fire extinguishing device

1) Perfluorohexane fire extinguishing agent: Perfluorohexane is selected as the fire extinguishing agent, which is liquid at room temperature and quickly vaporizes after being sprayed by an atomizing nozzle. Through the dual effects of physical cooling and chemical inhibition of chain reactions, the fire is quickly controlled and prevented from spreading.

2) Customized nozzle design: Customize nozzle design based on the specific structure and layout of the electrical cabinet to ensure that the fire extinguishing agent can evenly cover the entire fire area.

3) Quick response mechanism: Once signs of fire are detected, the fire extinguishing device will immediately activate and quickly release the fire extinguishing agent into the electrical cabinet, achieving a second level response.

3. Customized system layout

1) Flexible adaptation to different environments: Design different system layout schemes based on the differences between surface and underground environments in mines. For surface electrical cabinets, an open layout can be adopted; For underground electrical cabinets, special requirements such as explosion-proof and moisture-proof should be considered.

2) Optimize fire extinguishing effect: Adjust the parameters and configuration of the fire extinguishing system according to different sizes of electrical cabinets and fire risk levels to achieve the best fire extinguishing effect.

3) Reduce false alarm rate: Through customized design, reduce false alarms caused by environmental factors, and improve the reliability and stability of the system.

The way to prevent fire in surface/underground electrical cabinets in mines lies in the customized solution of using an automatic fire extinguishing system for electrical cabinets. This plan combines the actual environmental characteristics of the mine, adopts advanced fire extinguishing technology and intelligent control methods, and provides comprehensive and efficient fire protection for electrical cabinets. With the continuous development of technology, the automatic fire extinguishing system of electrical cabinets will become more intelligent and efficient, providing a more solid guarantee for the safe production of mines and the stable operation of power systems.
