MATHEMATICAL MODELING OF HEATING PROCESSES IN CONDUCTORS OF INTERNAL ELECTRICAL NETWORKS IN HOUSING AND PUBLIC BUILDINGS

Abstract

The heating processes of copper conductors of electric power in residential and public buildings within the flow of currents of different sizes by mathematical modeling are investigated. The models which make possible to calculate the heating wires to fire temperature depending on the value of current and set the time of heating to acceptable lengthy and critical-temperature for insulating materials with different cross sections of the conductor are proposed. Installed results can be used in choosing the specified internal electric power protection devices.
