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
