Etc. being configured, processing logic is constant.It is all that last fire extinguishing is realized by two steps.The first step before battery is not burst, works as electricity
The processing of gas fire, starts GAFES, carries out aeresols fire extinguishing.Second step, battery temperature is still after extinction using gas
Rise, then starts water filling fire extinguishing system, carry out water filling fire extinguishing.
Extinguishing device of the invention can combine carry out using, realized by multiple battery compartments, water filling fire extinguishing system according to
Obtained battery fire fire extinguishing signal judges the battery compartment that temperature exceeds normal index in turn, to control corresponding electricity
Magnet valve 2 open, to corresponding battery compartment carry out filling liquid (the liquid filling mode include but are not limited to top fluid injection,
The modes such as lower part fluid injection, spray), level detection sensor 9 is respectively arranged in each battery compartment, to avoid liquid from overflowing to influence
Other battery compartments operated normally work on, and when liquid position reaches certain value, level detection sensor 9 is made accordingly at once
Signal is passed to control system, then is issued and instructed by control system by movement, closes or adjust turning for water pump for solenoid valve 2
Speed increases liquid level in battery compartment no longer.Until inside battery energy completely consumes totally, then by staff by battery compartment
Liquid drains, and makees further maintenance processing.
Using liquid submersion fire extinguishing scheme, by filling liquid into battery compartment, until battery is totally submerged, make battery and sky
Gas (oxygen) isolation, while using the direct contact of liquid and battery, by convection circulation, the heat that battery failures are generated is fast
Speed belt is walked, and so that battery temperature is rapidly reduced to burning point and is put out open fire purpose hereinafter, reaching, and is fundamentally eliminated inside and outside battery unit
Then the burning in portion does further maintenance processing until battery cell module depleted of energy again drains liquid, so as to
Prevent second accident to cause damages to system and maintenance personnel.Using the structure of battery compartment, even if when spontaneous combustion occurs for battery unit
When, the normal operation of battery compartment where also only will affect the battery unit, without then causing large-scale fire-fighting accident, from
And the destruction of unrepairable is caused to entire energy-storage system.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
