MODEL OF FIRE PROTECTION OF ELECTRICAL NETWORKS AT THE PLACES OF CONTACT CONNECTIONS

Abstract

This model of the fire protection element belongs to the field of electrical engineering, namely switching devices in electrical networks with automatic shutdown, which directly react to exceeding the nominal temperature. We have researched the field of forming a model of fire protection of electrical networks. The proposed approach of forming a model of an element of fire protection of electrical networks in places of excessive consumer capacities, which allows to take into account and subsequently prevent an emergency situation due to overheating of electrical networks in places of excessive consumer capacities. Also, in order to ensure the unequivocal operation of the fire protection element, it is suggested to check the functionality of the device connected to the electrical network and the network itself. After conducting a number of experiments, the problems of fire protection of electrical networks in places of excessive consumer power were substantiated and solved, and elements were developed based on the socket module with the function of opening the electrical circuit in the event of overheating of the plug-socket connection with the presence of an indication of operability or tripping of the thermal fuse. On the basis of the results obtained, a model of fire protection of electric networks in connection points during excessive local heating was developed, as well as a change in the operating mode of the light indicator, which will allow the user to conclude that the thermal fuse has tripped, which will indicate the need for appropriate qualified replacement or restoration work sockets and plugs of the appliance
