Abstract

The invention discloses a lithium battery energy storage system cabinet automatic fire extinguishment device and system. The fire extinguishment device comprises an aerosol fire extinguishment system, a water injection fire extinguishment system, an electrical fire detection device, a battery fire detection device and a control system. The electrical fire detection device and the battery fire detection device are both arranged in an energy storage system cabinet. The aerosol fire extinguishment system, the water injection fire extinguishment system, the electrical fire detection device and the battery fire detection device are all connected with the control system. The fire extinguishment system comprises a control system, an aerosol fire extinguishment system, multiple water injection fire extinguishment systems, multiple battery fire detection devices, a water inlet mother pipe, a water outlet mother pipe and multiple battery bins. The liquid immersion type fire extinguishment scheme is adopted, batteries are isolated from air by injecting liquid till the batteries are completely immersed, heat generated by battery faults is rapidly brought away through convective circulation at the same time, combustion inside and outside battery units is fundamentally eliminated, and harm caused by secondary accidents to the system and maintenance personnel is eradicated.

Description

technical field [0001] The invention belongs to the field of fire extinguishing devices, and relates to an automatic fire extinguishing device and system for a lithium battery energy storage system cabinet. Background technique [0002] Electric energy is an indispensable and important resource in contemporary society. In recent years, with the development and use of a large number of portable devices, uninterruptible power supply systems and electric vehicles, the use of batteries is increasing. Rechargeable batteries, especially lithium batteries, rely on their long cycle life. , stable performance, no memory function and other outstanding features are widely used in all walks of life. However, in the application of energy storage systems, due to factors such as weather reasons, heat dissipation problems of energy storage cabinets, battery cell aging and overcharging that may occur in the working environment, spontaneous combustion accidents of battery cells are very likel...
