METHOD OF EXPERIMENTAL STUDIES OF FLAME SPREAD AND THE TEMPERATURE INFLUENCE OF FIRE IN THE ROOM OF A MOBILE COMMUNICATION BASE STATION

Abstract

A problem was identified regarding the economic feasibility of equipping the premises of a mobile communications base station with automatic fire extinguishing systems from the point of view of equipment protection. A lack of consistency between the requirements of DBN V.2.5-56:2014 and NAPB V.01.053-2016/520 was established. The most fire-hazardous elements of the premises of a mobile communications base station were determined. Criteria for assessing the fire hazard of a mobile communications base station were developed, and a list of equipment necessary for conducting experimental studies was also formed. A thermocouple layout scheme was proposed that most accurately reflects the location of fire-hazardous elements, allows for real-time temperature control and to detect the possibility of ignition of one element due to the burning of another, and to establish the possibility of fire spreading beyond the premises of the mobile communications base station. A methodology is presented that makes it possible to verify the proposed criteria in order to study the spread of flame through the telecommunications and electrical equipment of a mobile communications base station and the temperature effect of a fire in the base station premises on the temperature of its external walls.
