In mining operations, electrical cabinets, switchgear, and distribution boxes are core components of the power supply and distribution system. Whether located in surface beneficiation plants, hoist rooms, or within the complex environments of underground mining faces and substations, these cabinets perform critical functions. However, the harsh mining environment introduces numerous fire hazards. A fire can cause severe equipment damage, halt production, and even endanger personnel safety. Therefore, customized automatic fire suppression systems—specifically designed for electrical cabinets—have become essential for fire prevention in mining power systems.

Addressing the fire risks specific to mining electrical cabinets, the customized fire suppression system solution has been developed. This approach integrates the actual environmental conditions of the mine with advanced suppression technology and intelligent control methods to provide comprehensive and efficient protection.

1. Intelligent Detection and Alarm System

• High-Precision Sensors: High-accuracy temperature and flame detectors are installed inside the cabinet to monitor real-time fire indicators such as internal temperature and flame presence.

• Intelligent Algorithm Analysis: Data collected by the sensors is processed by intelligent algorithms. Upon detection of an anomaly, the alarm mechanism is triggered immediately.

• Diversified Alarm Methods: Alerts are communicated to operators through various means such as audible/visual alarms and remote monitoring terminals, prompting timely response measures.

2. High-Efficiency Fire Suppression Unit

• Perfluorohexane Suppressant: Perfluorohexane is selected as the extinguishing agent. It is a liquid at room temperature and vaporizes rapidly upon discharge through atomizing nozzles. It suppresses fires quickly through a combination of physical cooling and chemical interruption of the combustion chain reaction, preventing fire spread.

• Customized Nozzle Design: Nozzles are customized based on the specific internal structure and layout of the electrical cabinet to ensure the suppressant uniformly covers the entire protected volume.

• Rapid Response Mechanism: Upon detection of fire indicators, the suppression unit activates immediately, discharging the agent into the cabinet within seconds.

3. Customized System Design & Layout

• Adaptation to Different Environments: System layouts are designed according to the differences between surface and underground mining environments. For surface cabinets, standard layouts may be suitable. For underground installations, special considerations such as explosion-proof and moisture-resistant specifications are incorporated.

• Optimized Suppression Performance: System parameters and configurations are fine-tuned based on the size of the electrical cabinet and its specific fire risk level to achieve optimal performance.

• Reduced False Alarm Rate: Customized design helps minimize false alarms caused by environmental factors, enhancing overall system reliability and stability.

The path to effective fire prevention for mining electrical cabinets lies in the customized application of automatic fire suppression systems. This solution, tailored to the mine's actual environment and leveraging advanced technology and intelligent control, provides comprehensive and efficient protection for electrical cabinets. As technology continues to advance, these systems will become even more intelligent and efficient, offering a more robust guarantee for mine safety and the stable operation of power systems.
