Description

Fire spread prevention device in ESS electric room and fire extinguishing system using it

The present invention relates to a fire spread prevention device in an ESS electrical room and a fire extinguishing system using the same. It relates to a fire extinguishing system using the same.

In the existing ESS (Energy Storage System) electrical room, most of the electrical room is burned down during day and night when a fire occurs. In particular, in the ESS electrical room, the battery racks are densely arranged, so in the event of a fire, the fire spreads to the surrounding battery racks and is burned down. situation.

Until recently, there was no legal regulation on the internal structure of the ESS electrical room, so as many battery racks were placed as much as possible in the space provided inside the electrical room, it was inevitable to further increase the damage caused by fire.

In view of these problems, in recent years, regulations regulating the interval between battery racks have been made in the ESS electric room, and the interval between the battery racks is spaced apart from each other to be installed.

However, even if the ESS electric room forms a safe distance between battery racks, there is still a problem that when a fire occurs, it cannot prevent the fire from spreading to the surroundings and increasing damage because the battery cell generates high temperature and high heat due to the nature of the battery cell.
