Integrated lithium battery power supply cabinet

Abstract

The invention provides an integrated lithium battery power supply cabinet, which comprises a cabinet body, and a plurality of battery modules are arranged in the cabinet body, are connected in series and are managed and controlled through a battery management system. An independent safety assembly is arranged in each battery module and the cabinet body, the safety assemblies serve as a fire safety mechanism and are used for ensuring the overall stability and the electrical safety of the cabinet body, and when the safety assemblies detect that continuous sudden temperature rise, smoking or fire breaks out in the battery modules, mechanical triggering is achieved, and the safety of the cabinet body is ensured. After being triggered, the fire extinguishing agent is communicated with a tank body filled with a fire extinguishing agent, so that the fire extinguishing agent enters the battery module through a pipeline, is uniformly dispersed into the battery module from the top of the battery module, is quickly gasified and absorbs heat after entering the battery module, extrudes internal excess air, prevents a fire point from being in contact with the air, and realizes quick and effective fire extinguishing and fire point spreading prevention; the safety coefficient is high. The integrated lithium battery power supply cabinet is stable and reliable to use, has a mechanical active fire extinguishing mechanism, and is high in safety.

Description

technical field [0001] The invention relates to a power supply cabinet, in particular to an integrated lithium battery power supply cabinet. Background technique [0002] UPS is an uninterruptible power supply, which is an uninterruptible power supply with an energy storage device. It is mainly used to provide uninterrupted power supply to some devices that require high power stability. Uninterruptible power supply is a system equipment that connects the battery with the host, and converts DC power into commercial power through the host inverter and other module circuits. It is used to provide stable and uninterrupted power supply to rail transit, public security system computer room, data center, etc. [0003] Traditionally, lead-acid or colloidal batteries are used for power supply, which are large in size, short in life, high in building load-bearing requirements, and more harmful to the environment.

AI Technical Summary

Problems solved by technology

[0003] Traditionally, lead-acid or colloidal batteries are used for power supply, which are large in size, short in life, high in load-bearing requirements for buildings, and relatively harmful to the environment. Moreover, battery parameters are not easy to monitor and require regular inspections. Therefore, they have gradually been replaced by lithium batteries.

[0004] Due to its structural characteristics and the high energy density materials used, lithium batteries have the danger of explosion and fire during use, and the fire of lithium batteries is the release of internal energy.

When the lithium battery is thermally out of control, it will emit a mixture of high-temperature gas and particles. These gases are flammable and are prone to fire. The high-temperature ejection and the flame generated by the combustion of the ejection will heat the surrounding batteries and easily ignite the surrounding Batteries and even the entire electrical cabinet, traditional fire protection technology is difficult to effectively avoid the occurrence of lithium battery fires, most of the current safety problems are caused by the thermal runaway spread of lithium batteries, lithium battery fire protection technology has become a bottleneck restricting the development of the industry
