Fire-fighting device of container energy storage system and control method of fire-fighting device

Abstract

The invention discloses a fire-fighting device of a container energy storage system. The container energy storage system comprises a plurality of battery clusters, wherein the fire-fighting device comprises a gas fire extinguishing module, a liquid fire extinguishing module, a detection module and a control module; the detection module obtains smoke signals, temperature signals and / or gas signalsof the energy storage system; the liquid fire extinguishing module comprises a plurality of liquid fire extinguishing units corresponding to the battery clusters in a one-to-one manner; the liquid fire extinguishing units are arranged in the corresponding battery clusters; and the control module sequentially controls the gas fire extinguishing module and the liquid fire extinguishing units of theliquid fire extinguishing module to run according to the smoke signals, the temperature signals and / or the gas signals. The invention further discloses a control method of the fire-fighting device of the container energy storage system. By means of the fire-fighting device combining early-stage gas fire extinguishing and later-stage liquid fire extinguishing, the control level of the energy storage system during a fire disaster is improved, losses of the energy storage system after the fire disaster are reduced to the minimum, and losses of users are reduced.

Description

technical field [0001] The invention relates to the technical field of energy storage equipment, in particular to a fire fighting device for a container energy storage system and a control method thereof. Background technique [0002] Electrochemical energy storage is a reasonable solution to solve new energy consumption, enhance power grid stability, and improve the utilization efficiency of power distribution systems. It can play an important role in the entire power value chain, involving power generation, transmission, distribution, and consumption. link. In recent years, there have been fires and explosions in individual energy storage power stations at home and abroad. A battery cluster is a component containing energetic material and is by its nature hazardous. When the energy storage system is applied, a supporting fire protection system must be configured to improve the safety of the energy storage system and the surrounding environment. [0003] At present, most...

AI Technical Summary

Problems solved by technology

[0003] At present, most energy storage systems are equipped with heptafluoropropane fire extinguishing system, and a small part are equipped with heptafluoropropane water fire extinguishing system. Heptafluoropropane is mainly used in the initial stage of electrical fires. If it fails, it will lead to the expansion of fire accidents.

Although the water fire extinguishing system is highly reliable, the battery will be damaged after water fire extinguishing, resulting in the scrapping of the entire energy storage system and replacement as a whole
