Cable Fire Spread in Electronic Cabinet

摘要

According to the characteristics of the electronic cabinet fire, several cases of cable fire experiments with different ventilation rate in real scale electronic cabinet have been carried out. Temperatures of the cable flame and fume, as well as different location near the center of the conflagrant electronic cabinet were measured as a function of time. The results show significant effects of the ventilation rate on the temperature near the center of the cabinet and the concentration variation of CO and O_2, but the influence on the spread of cable fire is not obvious. The results provide useful reference for early warning and rapidly extinguishing fire of the electronic cabinet at the early stage.
