Charge cabinet fire extinguishing system and charge cabinet

Abstract

The invention discloses a charge cabinet fire extinguishing system and a charge cabinet. The charge cabinet fire extinguishing system comprises a charge cabinet body, charge cabinet battery compartments, a water tank, a single floating ball valve, a water pump, an emergency power supply, a water tank water adding unit, a fire extinguishing water inlet pipeline, a fire extinguishing water returningpipeline, a fire extinguishing nozzle and a smoke alarm, wherein the smoke alarm is triggered in case of fire in some charge cabinet battery compartment, devices in the charge cabinet body is immediately powered off, the emergency power supply 6 is started, then a water pump in the water tank is electrified, and finally a fire sprinkler in the charge cabinet battery compartment subjected to firesprinkles water. According to the charge cabinet fire extinguishing system, a main circuit of the charge cabinet can be immediately powered off when the fire in the charge cabinet is detected by the smoke alarm; the water pump is driven to pump through the emergency power supply, and the fire sprinkler is automatically started after being heated; the water can be recovered into a water tank againthrough the fire extinguishing water returning pipeline after fire extinguishing, so that the water is recycled, and the resource is saved; and the whole fire extinguishing system is independent fromthe main circuit, and mutual interference is avoided, so that the devices can run safely.

Description

technical field [0001] The invention relates to the technical field of charging cabinets, in particular to a charging cabinet fire protection system and a charging cabinet. Background technique [0002] For the emerging industry of charging cabinets and power exchange cabinets, inert gas or dry powder fire extinguishers are generally used as the main means of fire extinguishing. The advantage of this method is that it takes up less space and is not affected by external climate factors. The disadvantage is that As far as lithium batteries are concerned, if the temperature of the battery core cannot be reduced physically after a fire occurs, it will become very difficult to control the fire. Because the battery core will release oxygen by itself when it catches fire, which means that the battery core can spontaneously ignite without the help of oxygen in the external space, so the effect of inert gas and dry powder fire extinguishers will be greatly weakened. [0003] The spr...
