Description

Technical Field

[0001] The utility model relates to the field of energy storage power stations, and in particular to a safety monitoring and early warning device for energy storage power stations. Background Art

[0002] As a new energy battery, lithium-ion batteries are not only more environmentally friendly but also have better performance. They are widely used in energy storage power stations. However, during the storage process, lithium-ion batteries may experience thermal runaway due to the accumulation of heat from their own chemical reactions or the influence of external heat sources, which seriously affects the safety performance of energy storage power stations. At present, the early warning and fire protection of energy storage power stations are mainly achieved through the following methods: multiple different types of fire detectors (temperature sensing, smoke sensing or smoke-temperature integrated type) are set on the top of the energy storage power station to monitor the operation of the energy storage power station, and gas fire extinguishing devices and fire extinguishing agent delivery pipelines are installed. When a fire occurs, inert gas is used to extinguish the fire.

[0003] In the prior art, the overall monitoring of the energy storage power station is not accurate enough. When a battery in a single energy storage cabinet experiences thermal runaway, it may not be detected or detected slowly. When a fire is detected, the fire extinguishing agent is sprayed in the entire energy storage station space, which cannot accurately extinguish the energy storage cabinet where the fire occurred. The fire extinguishing effect on the energy storage cabinet is not good enough, and the fire source cannot be extinguished quickly, effectively, and safely. Therefore, those skilled in the art provide a safety monitoring and early warning device for an energy storage power station to solve the problems raised in the above background technology.
