The invention relates to a gas turbine package with fire protection, thermal insulation, ventilation and sound insulation functions. The gas turbine package comprises a box, a box wallboard, a ventilation system and a fire protection system. The box wallboard adopts a bilayer structure composed of a sound absorption layer and a sound insulation layer which both contain a partition board, the surface of which is sprayed with a material with a large sound loss coefficient. The insides of the sound absorption layer and the sound insulation layer are filled with thermal insulating glass silk floss. The ventilation system consists of a redundantly configured explosion-proof axial flow fan and an electrically driven inlet/outlet damper. The fire protection system includes extinguishing and discharge pipelines and nozzles, four flame detectors, a temperature detector, and four combustible gas detectors, wherein, the four flame detectors, the temperature detector, and the four combustible gas detectors are respectively installed on the inner walls of the box, and the nozzles are disposed on the extinguishing and discharge pipelines. The device provided in the invention can work stably under a round-the-clock condition, and make the inside and outside of the box in a safe environment so as to protect the safety of on-site maintenance personnel and guarantee the normal operation of a gas turbine.
