Description

Technical Field

[0001] The utility model relates to the technical field of energy storage container equipment, in particular to a pressure relief port for a gas fire extinguishing system of an energy storage container. Background Art

[0002] Energy storage containers are mobile devices that integrate battery energy storage systems. They are usually designed and manufactured in the form of containers. They are mainly used to store and release electrical energy to meet temporary or emergency power needs. Energy storage containers can be charged in various ways, such as renewable energy equipment such as solar photovoltaic panels and wind turbines, or they can be powered by the grid. When it is necessary to release electrical energy, energy storage containers can directly output electrical energy to the grid, or provide independent power supply to areas far away from the grid.

[0003] The gas fire extinguishing system of the energy storage container is a system that automatically releases fire extinguishing agents to extinguish the fire in an emergency to prevent fires in batteries or other electrical equipment. Fluoride-free gas fire extinguishing agents are usually used. When a fire is detected, the system automatically triggers the release of the fire extinguishing agent and sprays the fire extinguishing agent into the energy storage container to suppress the fire source and extinguish the fire. This process will cause the pressure in the protected area to increase rapidly. If the high-pressure gas is not discharged in time, it may cause damage to the normal working equipment in the protected area, and may even cause damage to the closed protected area itself, and cause the fire to continue to spread, resulting in serious consequences.
