Cooperative Fire Extinguishing Technology of Battery Energy Storage Device in Cluster

摘要

The electrochemical energy storage device is equipped with an independent fire extinguishing device and distributed independently. In this paper, a connection pipeline and a bypass solenoid valve are arranged on the fire extinguishing equipment of the electrochemical energy storage device distributed in a distributed manner to connect the fire extinguishing devices into a network. Through the standardized graph theory path selection technology, the automatic detection and control of the fire-extinguishing medium cooling of the fire-extinguishing equipment in each electrochemical energy storage device is realized, which is controlled by the solenoid valve from far to near according to the distance of the connection path. The distributed electrochemical energy storage device does not need to reserve a large margin of gas cylinders, and the distributed cooling device realizes standby mutual benefit and collaborative cooling through this technology, which improves the reliability of the fire-extinguishing device and reduces the cost of fire-extinguishing equipment of the electrochemical energy storage device.
