MATHEMATICAL MODEL OF FIRE PROTECTION OF ELECTRICAL NETWORKS IN SWITCHING PLACES DURING EXCESSIVE LOCAL HEATING

The field of the mathematical model fire protection electrical networks in places switching excessive consumer capacities is within limits determined by operating temperature element system, which, turn, between maximum permissible plug-socket contact connection and destruction structural elements system protection, specified on one hand self-ignition materials other that are with or near system. at points a two analytical dependencies. first describes dependence main parameters capacities. second allows you to determine effective depending options for solving individual problems formation has been studied. purpose study develop during local heating. Reasoned solutions problem determining transient processes short circuit calculating jets time operation fuse have solved. On basis obtained results, heating was developed. Keywords: model, networks, places.
