RESEARCH OF TRANSIENT HEATING OF INSULATED CONDUCTORS IN ELECTRICAL SYSTEMS OF VIHECLES AFFECTED BY INSTANT HEAT IMPULSES

Abstract

The main electrical causes of vehicle fires have been analyzed. We have got the analytic dependence of the insulated wire heating temperature change involving the instant heat impulses, caused by electrical sparks with taking the thermal and physical characteristics and geometrical dimensions of the wire into account. It shows dependences of changing the temperature of wire from its design parameters and energy of the spark discharge. The results of numerical experiments are given in the form of graphic reproduction.
