Description
Technical Field
The utility model relates to the field of battery energy storage cabinets, in particular to a lithium battery energy storage cabinet with fire isolation protection and accurate fire protection functions.
Background
The energy storage system is an important ring of source network charge storage, can play roles in peak regulation, frequency modulation, peak clipping, valley filling, emergency power backup and the like, and is attracting attention in recent years. At present, lithium ion batteries have become a mainstream energy storage mode, and the safety of the lithium battery energy storage cabinet in the operation process is one of important factors for restricting the development of the lithium battery energy storage cabinet.
In the existing lithium ion battery energy storage cabinet, a detector adopts a mode of installing temperature sense and smoke sense on the top of the cabinet to judge whether the temperature or smoke reaches a set threshold, and when the temperature or smoke reaches the set threshold, the detector sends a signal to a fire control system to alarm or start a fire extinguishing device. The fire extinguishing mode mainly adopts cabinet level fire extinguishing, and when the fire extinguishing device is started to spray the fire extinguishing agent, the fire extinguishing agent sprays the whole cabinet from the spray head at the top of the cabinet. Common fire extinguishing media are heptafluoropropane and perfluorohexanone. The disadvantage of cabinet level detection and injection is that the fire position cannot be accurately judged, when the fire position is far away from the detector on the cabinet top, the starting speed of the fire protection system is very delayed, the fire extinguishing timeliness is low, and the fire is difficult to control in the initial stage of the fire. In addition, between each battery pack in the battery cabinet, each battery column is not isolated from fire prevention, so that fire spread cannot be effectively prevented, and the fire is controlled to be in a minimum range. The main connection circuit lines and the fire-fighting pipelines do not take fireproof and flame-retardant measures, and the fire-fighting system can be disabled after fire.
Disclosure of utility model
The utility model aims to overcome the defects of the technology and provide the lithium battery energy storage cabinet with the functions of fire isolation protection and accurate fire protection.
In order to solve the technical problems, the technical scheme provided by the utility model is that the lithium battery energy storage cabinet with the functions of fire isolation protection and accurate fire protection is as follows: the lithium battery energy storage cabinet comprises a cabinet body, a battery pack, an air conditioner and a BMS, wherein the battery pack is provided with a plurality of batteries and is arranged in two rows; the battery pack is characterized in that a fireproof isolation plate is arranged in the middle of each battery pack, fire protection pipelines and control circuits in the battery packs, air conditioners and cabinet control circuits are wrapped with fireproof belts, temperature sensing early warning fireproof coatings are coated on the surfaces of connecting ends of the battery packs, fireproof plugging plates are arranged in through holes in the bottom of each cabinet body, the fire protection pipelines are arranged in the cabinet body and extend to each battery pack, each battery pack is provided with a hole and is provided with a fine water mist and gas combined spray head, the combined spray heads are connected with the fire protection pipelines, fire detection pipes are connected to ends of the combined spray heads, and the fire detection pipes are wound through air release valves of each battery cell in a U-shaped mode in the battery packs.
Compared with the prior art, the utility model has the advantages that: 1. fire disaster can be controlled to be in a minimum range by arranging fireproof isolation among the battery packs, so that the fire disaster is prevented from spreading; the fire protection package is arranged on the surfaces of the fire protection pipeline and each control wire harness, so that control and fire protection failure caused by fire can be avoided; the temperature-sensing fireproof coating is arranged on the cabinet bottom and the wiring terminal, so that the cabinet can prevent fire and moisture, sense temperature and play a role in fireproof early warning; the whole cabinet-level fire-fighting injection can be avoided through the package-level fire-fighting design, and the fire extinguishing agent is saved, so that more effective fire extinguishing can be realized; the temperature detection pipe which is wound to each electric core through the U-shaped structure in the battery pack can detect the temperature close to the electric core, is more accurate and more timely than a temperature-sensitive detector arranged on the top of the cabinet, and can accurately spray and extinguish the fire of the electric core after the electric core is out of control.
