Essay

Object - processes of fires in electrified premises due to the formation of a dangerous source of ignition of combustible material near the site of injury possible network failures and appropriate remedies; methods - an integrated approach of research, which includes: an analysis of statistical data on fires and regulatory framework for assessing the reliability of the parameters and operation of electrical devices; systems analysis to establish causal relationships between the factors affecting the frequency of occurrence of fire protection, electrical source of ignition and ignition of combustible material; methods of probability theory; experimental research methods using standard measurements of electrical devices; novelty - the first time an analytical dependence of the probability of ignition of combustible material in the premise electrified during the year on the frequency of occurrence of dangerous electrical source and the duration of its existence, reliability, protection, and timing of their diagnosis, taking into account the frequency of occurrence and duration of stay of combustible material near the possible occurrence of an ignition source, allowing sufficient for practical calculations accurately assess and predict the level of fire danger object; the parameters of reliability and timing device diagnostics protect low-voltage supply network, as well as the time interval between checks of combustible material, which eliminates the occurrence of ignition of combustible material in electrified premises and thus ensure the safety of those people in them; depending on the experimental set intervals until melted polyvinylchloride insulation electrical wiring at different multiplicity overload currents for copper and aluminum wire and cable, as well as the dependence of the heating and cooling power contact joints with continuous electrical arcing that allows to prove the feasibility of remedies designed. Methods have been developed and designed by a regulation that allow the design stage to calculate the parameters of assessing the level of explosion and fire safety systems of power supply premises; developed a new system to prevent cases of fire of combustible material in the premises with electric and gas energy, consisting of patented devices and diagnostic method of low-voltage electrical network, which prevents fire from combustible material, dangerous electrical ignition sources; developed an experimental model of the module and secure interconnection and mutual exploitation of electricity and gas supply systems; results are used in the educational process of the SHEI "DonNTU". The results can be useful for creating new devices, providing safe exploitation of electrical equipment of apartments of the production and domestic setting.
