A distributed fire-fighting system for a battery energy storage cabinet comprises a plurality of cabinets which are orderly arranged from top to bottom and from left to right. The surface of the cabinet is provided with a fire-fighting system triggering/detecting device; the composite detection effect of the sensor is more accurate. The fire-fighting system triggering/detecting devices of all the cabinets are connected in parallel; the fire extinguishing devices on the single cabinet can be controlled by the fire control module, and the fire extinguishing devices are connected in parallel, so that the fire in one cabinet can be guaranteed, and the normal detection and judgment of other cabinets can not be influenced. The fire-fighting system triggering/detecting device comprises a particle concentration detecting circuit and a temperature detecting circuit which are respectively connected with the fire-fighting control module; whether fire hazard exists in the cabinet can be judged by comparing the temperature with the particle concentration and the limiting value, a fire signal can be directly transmitted to the fire control module through connection between the fire control system triggering/detecting devices, and the fire signal is transmitted to the background main control system through a wireless network. A high-precision smoke and gas composite detector is adopted to effectively detect smoke particles emitted by fire.
The whole fire fighting system is powered by the fire fighting control module.
A puncture valve 1 is arranged on the surface of each cabinet; when the puncture valve 1 is not punctured, the interior of the machine cabinet is kept in a normal closed state, a spray head 2 is arranged between the puncture valves 1 of two adjacent machine cabinets side by side, the spray head 2 is connected with a fire-fighting gas bottle 3 arranged on the outer side of the machine cabinet, and fire-fighting gas can be directly provided through the fire-fighting gas bottle 3. The distributed hair spray design can be arranged according to requirements. Meanwhile, the distributed type eruption design can be flexibly arranged. And the spray head 2 is connected with the fire control module and is controlled by the fire control module. The fire-fighting gas cylinder 3, the spray head 2 and the puncture valve 1 are connected in sequence. The fire-fighting gas cylinder 3, the nozzle 2 and the puncture valve 1 are connected by adopting a flame-retardant gas pipe; the pipelines are connected with the spray heads 2 from the top of the cabinet downwards in sequence. The fire-retardant trachea can effectively prevent the damage of conflagration to pipeline itself, guarantees that when the conflagration takes place, extinguishing device can be effective and direct put out a fire to the inside of rack from puncture valve 1. The fire extinguishing materials such as heptafluoropropane and perfluorohexanone can be used compatibly, so that the fire can be effectively extinguished without damaging equipment. The heptafluoropropane and the perfluorohexanone and other fire extinguishing materials can be compatible for use, so that the fire can be effectively extinguished without damaging equipment. The fire extinguishing material is more suitable for battery application scenes.
Early warning and fixed point eruption are carried out through highly integrated system, reduce the influence of foam to whole rack group when putting out a fire, and can in time be accurate eliminate the ignition source, can in time feed back higher level management system with fault information simultaneously.
When the device works, the spray head 2 and the sensor are arranged according to the requirements of the cabinet; the nozzle 2 is connected with the fire-fighting gas cylinder 3 by a flame-retardant gas pipe; when the concentration or the temperature of the combustion particles is detected to reach an alarm limit value, alarming is carried out, information is transmitted to a system to be controlled, the system is required to stop working, and overhauling is carried out; when the concentration or the temperature of the burning particles is detected to reach a eruption value, the position of the fire extinguishing device is detected to perform fire extinguishing gas eruption operation and continuously give an alarm.
When fire is needed to be extinguished, the puncture valve 1 is opened, and the adjacent spray heads 2 spray extinguishing materials to the position of the puncture valve 1 through pipelines so as to extinguish fire at fixed points. And this action can not influence the normal use of other cabinets, and can directly put out a fire to inside fire hidden danger point through outside gas cylinder, and fire control effect is better than the outside fire control cabinet of putting out a fire, and compares traditional single cabinet inside and sets up the redundant fire extinguishing position, and this fire extinguishing system has reduced the inside redundant setting of cabinet, has increased the integrated level of cabinet.
