Abstract
Given the rapid development of urban rail transit across the country and the differences in fire power supply design among different regions,a complete urban rail transit fire fighting power supply design benchmark scheme is provided as a reference.The complete fire fighting power distribution chain of urban rail transit stations starts from the low-voltage switchgear,and through the laid cables,electrical energy is transmitted to the fire fighting equipment.Focusing on the three elements of power supply,circuit,and fire load,through the study of a large number of specifications,standards,and literature,the continuous power supply time requirements of various professional electrical equipment in case of fire is deeply analyzed,the design requirements for fire protection lines are standardized and the different continuous power supply times that fire protection distribution lines need to achieve are determined.On this basis,combined with the current classification and testing standards of domestic fire-resistant cables,reasonable cable selection and laying method selection are carried out to obtain a standardized and reasonable fire fighting power supply design benchmark scheme.Benchmark reference is provided for the design of fire fighting power supply for a variety of rail transit in different regions,it has important reference and guiding significance for ensuring the reliability and rationality of fire power distribution.关键词
