The invention provides a method for determining an electrical fire risk evaluation weight index coefficient. The method comprises the steps: building different types of electrical fault models, carrying out the electrothermal coupling according to the fault characteristics, analyzing the thermal effect of an electrical fault, and obtaining an electrical fire simulation parameter; establishing a basic building scene model, and performing electrical fire simulation in the established basic building scene model to obtain electrical fire risk data; establishing an electrical fire risk evaluation comprehensive evaluation system by using an analytic hierarchy process; and comparing and scoring the electrical fire risk data according to the established electrical fire risk evaluation comprehensive evaluation system to obtain comprehensive scores of the residential building electrical fire and the public building electrical fire, and obtaining an electrical fire risk evaluation weight coefficient. According to the method, the electrical fire risk comprehensive evaluation system is established by innovatively applying the simulation analysis and analytic hierarchy process, and the reliability and accuracy of the electrical fire risk evaluation weight index coefficient can be improved.
Description
technical field [0001] The invention relates to the field of risk assessment of electrical fires, in particular to a method for determining weight index coefficients of electrical fire risk assessments. Background technique [0002] According to statistics, electrical fires accounted for 31% of the total number of fires from 2012 to 2020, and there is a tendency to continue to rise, especially the proportion of large fires and major fires. A large number of fire statistics show that electrical fires have been at the top of all types of fire statistics for many years, both in terms of fire causes and direct economic losses. The fire risk of different types of electrical faults is different, so it is particularly important to analyze the electrical fire risk according to the type of electrical fault. [0003] At present, the determination of the weight coefficient of electrical fire risk assessment is mainly based on past experience and expert analysis. error. Therefore, it...
