Система попередження вибухопожежонебезпечних ситуацій в об’єктах, пов’язаних із життєдіяльністю людини

Abstract

The article analyzes the situation with fires and explosions in the objects associated with human activity. Identified the most critical factors that reduce the overall level of explosion and fire risk at the object of mutual exploitation of electricity and gas. Made a critical analysis of existing developments which are formed on the basis of system requirements prevent explosions and fires in objects. Provides a method and scheme of the system with the description of the algorithm operation. The system prevents explosive situations works as follows. In each room near gas devices a sensor of natural gas leakage is housed with the possibility of signal transmitting via radio, in addition, each room has its own section of the wiring, which consists of electrical boxes 4 (Wiring box for residential electric power is used [6], which include a monitoring scheme for terminal blocks state), 5 lighting, electrical outlets 6 (socket is applied [7], which contain circuit contact state monitoring scheme and protection against overloads, short circuits and electrical arcing and sparking), lighting switches 7 (is applied switching device [8], which implements intrinsically safe switching scheme and contains remote control) and power wires, that are shown by lines 13. All site wiring are connected to a single system of internal power supply via intrinsically safe switching devices 2 [8] that are able to receive the signal via radio and are arranged in Low voltage device kit 3 (is applied Low voltage device kit [9] which contains an automatic fire risk dust removal system). Fire and explosion hazard prevention system in the objects associated with human activity is proposed, making it possible to increase their safety to the normal level, according to [5], by reducing the probability of explosion and fire hazard for electrical systems operating in potentially flammable atmospheres appearance and an ignition sources appearance. In addition, the human factor is excluded in the housing sector through patented technical solutions using. The involvement of employees of gas and fire emergency services who will come for the alarm is important, they will enable the lighting in the room with dangerous levels of natural gas only after the removal of emergency leaks, which will help to avoid possible electrical ignition sources in the form of switching sparks of light switches and other electrical equipment.
