Study on quantification scheme of weight coefficient for electrical fire risk assessment of high-rise building

Abstract

Electrical fire is a very important fire type in high-rise building fire. Therefore, it has high research value for risk assessment of electric fire in high-rise buildings. However, it is difficult to accurately obtain the weight index coefficient of electrical fire risk assessment by single qualitative or quantitative risk assessment method, so the reliability and objectivity of electrical fire risk assessment cannot be guarantee. In order to solve this problem, a method of using numerical simulation to obtain different types of fire risk data is proposed. Then, taking fire risk influencing factors as the research object, a comprehensive fire risk evaluation system is established. Through the comprehensive evaluation system, the electrical fire risk data are evaluated to determine the electrical fire risk weight coefficient. The results show that the fire risk quantification scheme of weight coefficient proposed in this paper can eliminate the subjectivity of traditional expert ratings. The proposed evaluation standard is a comprehensive evaluation system based on the numerical simulation and analytic hierarchy process. Above mentioned method can improve the reliability and accuracy of the weight coefficient of electrical fire risk assessment, and provide a theoretical basis for the research and classification of fire risk.

Technical research on test method of the socket and switch of temperature monitoring alarm function

“…For temperature alarms of switches and sockets, it is necessary to directly heat their terminals, and to be able to control the temperature accuracy of the heating rate. None of the above four methods can satisfy the reality of direct and rapid heating of switches and sockets, and does not affect the normal operation of the product demand [8,12].…”
