TOTAL SATURATION SYSTEM IN ELECTRIC TRAIN CARS Russian patent published in 2016 - IPC A62C13/22 

FIELD: fire safety.

SUBSTANCE: invention relates to stationary controlled systems of detection and suppression of fires in electric train cars. Total saturation system in electric train cars comprises fire and smoke signalling devices and extinguishing aerosol generators distributed in protected volumes. Electric ignitors of pyrotechnic cartridges of fire extinguishing aerosol generators are connected with an autonomous source of electric current by means of a button of the switch of manual switching external unit. Self-contained electric current source is a battery from pyrotechnic flat electrodes with an igniter capsule. Igniter capsule interacts with the switch, which is made in the form of a percussion mechanism, its spring-loaded sting is fixed on the button of manual switching and kinematically closed with the bearing holder by means of a pin, wherein the independent switches in the communication lines with electric igniters of backup fire extinguishing aerosol generators are directly connected with pyrotechnical battery of electric current.

EFFECT: proposed engineering solution ensures simple design of the fire extinguishing system in different modes of action.
