[0002] Closed prefabricated warehouses are widely used in the fields of electricity, communications, data centers, etc. They usually contain switch cabinets, PT cabinets, metering cabinets, station transformer cabinets and their secondary monitoring, communication, protection, batteries and other equipment. They are independently closed and unattended. These devices may cause fires due to electrical failures, overheating or other reasons during operation. Due to the closed space and dense equipment of prefabricated warehouses, the risk of fire is relatively high. When a closed prefabricated warehouse catches fire, it is very likely to spread to other closed prefabricated warehouses or other equipment, causing unnecessary losses. However, there is no independent fire extinguishing system for a single closed prefabricated warehouse in the prior art.
