Abstract：In view of the relevant specifications,such as the setting of self‑contained power supply,emergency power supply system,continuous power supply time of electric equipment,standby power supply of security system,etc.,the type,applicable occasions,setting principle and continuous power supply time of the self‑contained power supply are summarized and discussed. Combined with the actual engineering design,the self‑contained power supply system,the selection of self‑contained power supply and other solutions are proposed.

Key words：self‑contained power supply;emergency power supply;standby power supply;diesel generator unit;uninterruptible power supply(UPS);emergency power supply(EPS);continuous power supply time;allowable time of interrupted power supply
