Description
Technical Field
The utility model relates to a temperature detection fire extinguishing system for energy storage electric cabinet relates to lithium ion battery energy storage temperature detection field of putting out a fire.
Background
The energy storage system is used as an auxiliary energy system, can play roles in peak-shaving frequency modulation, emergency power supply and the like, and is more and more concerned by people in recent years. In an energy storage system, a system using a lithium ion battery as an energy storage mode gradually occupies a mainstream, and safety performance in an operation process of the system is very important. Because lithium ion batteries have poor thermal stability compared to conventional lead acid batteries, there is a risk of fire due to heat generation during operation.
In the existing lithium ion battery energy storage electric cabinet fire-fighting system, the main temperature detecting mode is that whether the temperature reaches a critical value is judged through a temperature sensor, and when the temperature reaches the critical value, the sensor sends a signal to a fire-fighting control system to give an alarm or start fire-fighting action.
The main fire extinguishing mode has two kinds, one kind is to adopt the pipeline formula fire control, arranges the fire control shower nozzle near the internal battery package of cabinet, when taking place conflagration or reporting to the police, thereby the fire control medium is from the gas cylinder via the pipeline transport, thereby plays the effect of cooling down and putting out a fire from the blowout of fire control shower nozzle. Common fire fighting media are heptafluoropropane, perfluorohexanone, and water.
Another is an aerosol-type fire suppression system, which does not require fire-fighting piping. The operating mode is that the aerosol is arranged near the battery pack, when the temperature exceeds a critical value, the aerosol fire extinguishing system receives an electric signal, and the aerosol spray with the flame retardant effect is sprayed out through internal reaction, so that the effects of cooling and extinguishing fire are achieved.
The pipeline type fire fighting and the aerosol fire fighting have the defects that the fire position cannot be accurately judged, and the timeliness of fire fighting is low. Because pipeline formula fire control and aerosol fire control mostly adopt temperature sensor as the signal source of start-up, and temperature sensor can only survey the temperature of a certain position in whole region, has the unicity. The ignition point of the lithium battery is not a certain determined position, and when the ignition point is far away from the temperature sensor, the starting speed of the fire-fighting system is low, so that the fire condition is difficult to control at the initial stage of the fire.
In addition, the nozzles for pipeline and aerosol fire protection are also single-point, and when the nozzles are far away from the fire point, the fire-fighting medium reaches the fire point slowly, which also causes the reduction of the fire-fighting speed.
Therefore, the temperature detection and fire fighting functions of the lithium ion battery energy storage system are very important.
