With the continuous development of new energy technology, energy storage containers are more and more widely used in the energy field. However, because the energy storage container is a high-energy battery pack, the consequences of a fire can be unimaginable. Therefore, the design of the fire protection system of the energy storage container is particularly important.
The fire protection system design of energy storage containers needs to consider many aspects, including detection, isolation, suppression, alarm and fire extinguishing. Here are some key design considerations:
Detection: Fire detectors are installed inside the container to detect smoke and heat in the event of a fire. Choose the type of detector that is appropriate for the environment inside the container, such as photoelectric smoke detectors or thermal line detectors, and ensure that the detector coverage is able to fully monitor the inside of the container.
Isolation: Set up fire separation around each battery cell or battery module of the container to limit the spread of fire. Fire barriers can use refractory materials such as fireproof board or fireproof coatings to ensure that the spread of fire can be delayed or stopped in the event of a fire.
Inhibition: Installation of fire extinguishing agent spraying devices inside the container to extinguish fires. Depending on the type of battery and the choice of extinguishing agent, dry powder, gas or foam extinguishing agent can be used. Before spraying the extinguishing agent, it is necessary to ensure that the fire is under control to avoid injury to personnel and equipment.
Alarm: A fire alarm is installed inside the container to sound a fire alarm and indicate the location of the fire source. The alarm should have sufficient volume and visual cues to ensure that personnel can receive the alarm in time and take appropriate action.
Fire extinguishing: In addition to the fire extinguishing device inside the container, external fire extinguishing equipment such as portable fire extinguishers and fire hoses should be equipped. In the event of a fire, personnel can quickly use these devices for fire extinguishing operations.
To sum up, the design of the fire protection system of energy storage containers needs to comprehensively consider multiple aspects such as detection, isolation, suppression, alarm and fire extinguishing. Select appropriate equipment and solutions according to the actual situation, and carry out regular maintenance and inspection to ensure the reliability and effectiveness of the fire protection system.
The fire protection system adopts fire alarm control device for energy storage power station. A composite detector is set up in the battery compartment, and a temperature detector, smoke detector and alarm bell are set up in the electrical compartmentSet up a gas release indicator light and an audible and visual alarm outside the exit of the protection areaSet an emergency start-stop button outside the exit of the protection zone. A cabinet-type heptafluoropropane gas fire extinguishing device is set up in the protection area, including a fire extinguishing agent storage container, a container valve, a fire extinguishing agent, an electromagnet starting device, a nozzle, a pressure display, a pressure signal feedback device, etc.
