firstly spraying water for inhibition, and then spraying aerosol for extinguishment: after the batteries in the battery box are out of control due to heat, a large amount of combustible gas is firstly emitted, at the moment, fire is probably not generated, at the moment, water is continuously sprayed for temperature reduction and inhibition, and the probability of out of control due to heat conduction of other batteries and even the probability of out of control due to heat of the batteries in all cabins is reduced; if open fire still produces in the water spraying process, because there is the dead angle in the water system injection, open fire probably can't be put out, need start aerosol at this moment and put out a fire, and the water system lasts the work during, carries out the cooling and suppresses whole cupboard always.
Spraying sol for fire extinguishing, and spraying water for inhibition: after a battery in the battery box is in thermal runaway fire, if the battery is not extinguished in the first time, the temperature of flame can cause the thermal runaway of other batteries to increase the fire risk, so that the open fire can be extinguished by spraying aerosol in the first time after the open fire is started; the aerosol volume that the cabinet body can install is limited, therefore the medicament dosage is also limited, and the time of restraineing is also limited. Therefore, after the aerosol extinguishes the open fire, the temperature reduction and inhibition are carried out by continuously spraying water.
The water system and the aerosol are sprayed simultaneously to inhibit and extinguish fire: in order to guarantee the success rate of putting out a fire, the water system and the aerosol start simultaneously can be very big improvement the success rate of putting out a fire, and just the very first time after putting out a fire is cooled down the suppression processing to the battery box that the heat is out of control, reduces because of the heat-conduction leads to the risk of other battery heat out of control.
The fire extinguishing module is mainly used for detecting fire conditions, extinguishing fire and sending feedback signals, the fire control board generates control signals according to the received feedback signals, and the water cooling inhibition module is controlled to act to spray water for cooling in the cabinet.
The cabinet of changing electricity in the above-mentioned embodiment can in time detect and implement effective measures such as putting out a fire, cooling suppression when taking place the condition of a fire, adopts extinguishing device and water suppression dual protection, has greatly improved the security performance of the cabinet of changing electricity.
