Abstract

The invention discloses a lithium battery energy storage unit fire extinguishing system capable of realizing echelon early warning and multiple accurate spraying. The lithium battery energy storage unit fire extinguishing system comprises a power management system, an early warning control system and a first extinguishing device, wherein the early warning control system is connected with the powermanagement system; the fire extinguishing device is connected with the early warning control system; the fire extinguishing device is externally connected with a temperature sensing fire detection pipe, a large-flow release pipeline and a local release pipeline; and the early warning control system is externally connected with a local data summarization module and a lithium battery energy storagepack. The fire extinguishing system is set to perform cyclic detection according to a fire signal and can repeatedly send a starting signal to realize multiple starting, so that the lithium battery fire is restrained for a long time, and the after-combustion problem is solved; the fire risk can be early warned in advance, the early warning response speed is increased, and fire can be controlled in the initial stage to realize inhibition; and accurate detection and accurate fire extinguishing are achieved, and the fire extinguishing efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of fire extinguishing devices, in particular to a fire protection system for cascaded early warning and multiple times of precise discharge of lithium battery energy storage units. Background technique

[0002] In recent years, as lithium batteries have many advantages such as high energy density, high output power, and long charge and discharge life, they have been widely used in the fields of transportation power, electric energy storage, and mobile communications, and have developed into my country's energy strategic. part of the emerging industry. However, with the in-depth application of lithium batteries in engineering, the problem of fire safety has become increasingly prominent. Since lithium batteries are energetic substances, especially when they are overheated, short-circuited, squeezed, etc., they will generate a lot of heat, causing fire hazards. The chain reaction of internal electrode material...
