According to different Disaster Grades, it is divided into level-one early warning, second level warning and three-level warning；
As VOC, CO, H2Etc. gas concentrations be more than a certain concentration when or 110 displays temperature of temperature monitoring module be more than a certain threshold
When value, the level-one early warning of energy storage shelter will be triggered；
When flame detector 101 detects the fire that electrical equipment causes, the second level that will trigger energy storage shelter is alerted；
As VOC, CO, H2Etc. gas concentrations be more than a certain concentration, and 110 displays temperature of temperature monitoring module be more than a certain threshold value
When, also the second level for triggering energy storage shelter is alerted；
Thermal runaway occurs for many places battery core inside energy storage shelter, and after extinguishing chemical release terminates, fire is not still had
Effect containment, the three-level for the system that triggers is alerted；
The level-one early warning of energy storage shelter, second level warning and three-level warning will all be uploaded to the pipe of user and supplier by network
Platform.
It can be detected in energy storage shelter by gas-monitoring module 106 in air-cooled pipeline 107 or flame detector 101
Portion whether there is security risk, after determining that fire or battery generation thermal runaway occur for electrical equipment, pass through temperature monitoring mould
Block 110 can quickly position the electrical equipment or battery module that the condition of a disaster occurs.
According to different early warning or warning level, implement different fire-fighting Disposal Strategies；
When level-one early warning is triggered, by according to different trigger sources, different methods is taken: if it is VOC, CO, H2Equal gas
When bulk concentration is more than a certain concentration, then the outer circulation mode that will start immediately complete hot heat-exchanger 103, realizes breath
Renew with air；If it is 110 displays temperature of temperature monitoring module be more than a certain threshold value, then will by indoor sound and light signal,
Signal of communication informs administrator, reinforces monitoring, and machine replaces corresponding battery module in due course, eliminates danger；
When the warning of system second level is triggered, starts the pump working in fire-fighting host 108 immediately, open simultaneously generation thermal runaway
Battery module where battery cluster bottom pipe electromagnetic valve 109, discharge pipeline 104 by spraying by extinguishing chemical to entire battery cluster
In battery module carry out firing-fighting medium atomizing crawl release.In order to comprehensively inhibit thermal runaway diffusion as far as possible, also will
It recycles and opens the extinguishing chemical spray release pipeline 102 for being located at cabin top, immersion fire smothering is carried out to energy storage shelter inside,
When the steam of firing-fighting medium is in volume fraction 4%-6%, that is, it can reach good extinguishing effect.It recycles crawl for several times, releases every time
If putting the firing-fighting medium of dry capacity.By recycling crawl, the long-acting inhibition of temperature in battery module can be realized, prevent re-ignition.
The high temperature firing-fighting medium steam generated in battery module, via the outer circulation mode of air-cooled pipeline 107, discharge is out of my cabin；
When the warning of system three-level is triggered, the extinguishing chemical for opening whole firing-fighting mediums discharges pipeline 104 and extinguishing chemical spray by spraying
Remaining liq in the liquid reserve tank of fire-fighting host 108 is all discharged, forms the submergence of firing-fighting medium steam by leaching release pipeline 102.Such as
Without residue in the liquid reserve tank of fruit fire-fighting host 108, then turn on automatically external secondary water fire-fighting connecting pipe or fire cistern etc.
Secondary water fire-fighting connecting pipe 401 discharges pipeline 104 and extinguishing chemical by the extinguishing chemical of the firing-fighting medium in energy storage shelter by spraying
Spray release pipeline 102 to carried out in energy storage shelter continue fire extinguishing or immersion dispose.
It should be strongly noted that in the application by air-cooled pipeline 107, refrigeration machine 111, complete hot heat-exchanger 103,
Gas-monitoring module 106, extinguishing chemical discharge pipeline 104, extinguishing chemical spray release pipeline 102, extinguishing chemical conveyance conduit by spraying
112, the cooperation of the components such as fire-fighting host 108, flame detector 101, temperature monitoring module 110, realizes the heat of energy storage shelter
The whole design of management system and fire-fighting system, fundamentally improves the essential safety of energy storage shelter, and heat management system guarantees
The uniform and temperature in temperature field；Fire-fighting system can not only deal with the fire by electrically causing, but also can deal with lithium from
Sub- battery is in charge and discharge process due to the fire explosion of various unexpected factors initiation.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.No
It should treat any reference in the claims as limiting the claims involved.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
