Abstract:
In the current national design codes and standards, there are definite provisions for the cuttingoff of the nonfirefighting power supply, however, there are no specific provisions on the purposes, manners (manual cuttingoff manner or automatic cuttingoff manner) and positions of the cuttingoff of the nonfirefighting power supply. In this article, analysis is made on the purposes, manners (manual cuttingoff manner or automatic cuttingoff manner) and positions of the cuttingoff of the nonfirefighting power supply. The main principles and purposes of the cuttingoff of the nonfirefighting power supply in case of fire are defined, i.e., trying to avoid passenger chaos and secondary incident, trying to avoid further spread of the fire, trying to ensure the safety of the firefighters and trying to minimize the power cuttingoff scope. Finally, the principles, manners and positions of the cuttingoff of the nonfirefighting power supply in case of fire occurring in the equipment area and public area of Metro stations are proposed on basis of the features of the power load and operation management of Metro stations.
Key words: Metro station, fire disaster, cuttingoff of nonfirefighting power supply, firefighting coordination
