The present invention provides equipment for preventing flame diffusion for an underground electric power line. The equipment for preventing flame diffusion for an underground electric power line comprises: an underground power line structure having a floor forming a plurality of areas based on a ceiling, a wall, and prescribed boundaries; a fire detection unit which is installed on the ceiling, and detects smoke and a temperature caused by a fire in the areas; and an air spray unit which is installed on the floor of the underground power line structure, is installed to form intervals along the prescribed boundaries to be lifted and lowered, and sprays air to a corresponding area among the areas where an amount of smoke detected in the areas by the fire detection unit is relatively large or a detected temperature value is relatively high towards the outside to forcibly guide flames caused by the fire towards the outside. |
