What kind of fire protection requirements for batteries?

Battery fire protection requirements: The battery pack should be installed in a dedicated room, and the windows facing the sun should be ground glass or white-painted ordinary glass. Acid-resistant paint is painted everywhere in the room, and an explosion-proof door should be installed at the entrance of the battery room to prevent direct collusion with other rooms. The battery is mounted on the plate rack. Separate the battery and the plate frame, between the plate frame and the ground with isolation pads. But the battery plate racks below 48V can be installed without isolation pads. The distance between the battery and the wall shall not be less than 150mm. The aisle width of the battery compartment shall not be less than 1m when arranged on both sides; the one-sided arrangement shall not be less than 0.8m. A special acid conditioning room shall be set near the large battery room to store sulfuric acid and Prepare electrolyte. The storage battery room should be equipped with ventilation devices. The hydrogen, oxygen, and sulfuric acid gas released during charging should be discharged from all electrical appliances in the secondary battery room to meet explosion-proof requirements, and acid-resistant wires should be used for the lighting circuit. The room should be kept clean and there should be no undue combustibles to prevent heat and burning when it comes in contact with sulfuric acid. Meaning: The electrode is mainly made of lead and its oxide, and the electrolyte is a kind of storage battery with sulfuric acid solution. English: Lead-acidbattery. In the discharged state, the important component of the positive electrode is lead dioxide, and the important component of the negative electrode is lead; in the charged state, the important components of the positive and negative electrodes are lead sulfate. Divided into exhaust-type batteries and maintenance-free lead-acid batteries. The battery is mainly composed of tubular positive plate, negative plate, electrolyte, separator, battery tank, battery cover, pole, and liquid injection cover. The electrodes of the vented battery are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Important advantages are stable voltage and low price; disadvantages are low specific energy (that is, electric energy stored per kilogram of battery), short service life and frequent routine maintenance. Old-fashioned ordinary batteries generally have a life span of about 2 years, and it is necessary to regularly check the height of the electrolyte and add distilled water. However, with the development of technology, the life of lead-acid batteries has become longer and maintenance has become easier. The most obvious feature of lead-acid batteries is the unscrewed plastic sealing cover on the top and the vent hole on the top. These filling caps are used for filling pure water, checking electrolyte and exhaust gas. In theory, lead-acid batteries should be checked for the density and liquid level of the electrolyte during each maintenance. If there is a shortage, distilled water should be added. However, with the upgrading of battery manufacturing technology, lead-acid batteries have developed into lead-acid maintenance-free batteries and colloidal maintenance-free batteries. There is no need to add electrolyte or distilled water in the use of lead-acid batteries. The important thing is that the oxygen generated in the positive electrode can be absorbed in the negative electrode to reach the oxygen cycle, which can prevent the reduction of moisture. Lead-acid water batteries are mostly used in tractors, tricycles, car starting, etc., while maintenance-free lead-acid batteries have a wider range of applications, including uninterruptible power supplies, electric vehicle power, electric bicycle batteries, and so on. Lead-acid batteries are divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as car start batteries) according to their applications. When discharging progresses, the concentration of the sulfuric acid solution will continue to decrease. When the density of the solution drops to 1.18g/ml, stop using it for charging: 2PbSO?+2H?Ou003dPbO?+Pb+2H?SO?
