As a new type of vehicle that is driven by electricity and powered by batteries, electric vehicles for open-pit mining often catch fire due to local high temperatures, internal short circuits, external collisions, etc., resulting in fire accidents. However, the new energy industry has non-traditional fire safety risks that are different from those in the past, and it is necessary to implement the tactical principle of "control first, then eliminate". Once a fire breaks out, the fire develops rapidly, and fire extinguishing requires a strong initiative. Effective fire control is carried out in the early stages of fire formation, and early fire hazards are eliminated in a timely manner, so as to achieve the principle of extinguishing small, early, and early stages.
Faced with the characteristics of new energy electric vehicle fires: "rapid development, high heat dissipation, and difficult rescue", the new energy electric automatic fire prevention and extinguishing system explores new concepts and tactics for emergency rescue, and formulates effective fire detection and extinguishing performance by strengthening fire detection and fire extinguishing performance. Targeted fire extinguishing solutions integrate independent fire detection, alarm and fire extinguishing, effectively prevent and extinguish vehicle fires, and improve the fire emergency response level of mining electric vehicles.
The new energy power automatic fire prevention and extinguishing system uses perfluorohexanone as the fire extinguishing agent, which mainly focuses on physical cooling and chemical suppression. It is especially suitable for relatively closed places such as new energy battery cabins, photovoltaic boost stations, wind power stations, and computer rooms. Solve the problem of fire extinguishing in small spaces. Compared with other fire extinguishing devices, it is low in price, has strong fire extinguishing ability, and can extinguish fires without blind spots. It is the best choice in the field of fire extinguishing of power systems.
Secondly, the new energy power system fire prevention and extinguishing system adopts mechanical linear detection and single pipeline structure, which has a high degree of integration, small occupation volume, simple on-site installation and construction, and no need to lay any pipe network, effectively reducing construction costs and difficulties. At the same time, it can physically degrade on its own after fire extinguishing and will not cause damage to vehicles and equipment. It can achieve safe fire extinguishing while fully ensuring the safety of electrical equipment. It is one of the commonly used fire extinguishing products in power systems.
