Мodel for detecting and evaluating the fire hazard of spark discharges in the electrical networks of passenger cars based on the use of fiber- optic sensors

Abstract

The paper substantiates an approach to assessing the fire hazard of spark discharges in the electrical equipment elements of passenger cars of rolling stock based on the detection of optical flashes using fiber-optic sensors. The presented numerical model makes it possible to realize the possibility of detecting and evaluating optical flashes of weak spark discharges on potentially fire-hazardous electrical contacts in the electrical networks of passenger cars. To solve this problem, it seems appropriate to place sensors of electrical discharges using optical fibers to deliver to them the radiation of optical flashes of spark discharges from fire-hazardous spatially remote elements of the electrical network.
