    Abstract:Through the interpretation of Article 24 of Technical Requirements for Strengthening Fire Protection Design of Civil Buildings above 250 m(Trial)(GX[2018]No. 57),the power supply measures of fire load as“vital load in first grade load”are analyzed,and the use of diesel generator sets as the emergency power source,and several types of power distribution methods meeting the requirements that the“fire-fighting power supply circuit of the diesel generator sets shall be connected to the dedicated bus section with dedicated lines”are discussed. It is expected to arouse everyone’s extensive discussion and technical exchange, and improve relevant technical measures.
