The utility model relates to a ventilating, noise-reducing and cooling device for an unpowered electric transmission and transformation device and belongs to the electric protection field. The ventilating, noise-reducing and cooling device for the unpowered electric transmission and transformation device comprises a cable tunnel and a transformer station chamber, and a revolving exhaust fan is installed in an inspection pit of the cable tunnel. Joints of the cable tunnel and the substation chamber are communicated with each other through an air inflow pipe, and an exhaust fan is arranged at the position inside the substation chamber corresponding to the position of an outlet of the air inflow pipe. According to the ventilating, noise-reducing and cooling method and device, the problem that room temperature of a transformer room is too high when a substation in a city encounters a summer peak load period can be solved, and disputes of disturbance to residents caused by noises generated by fans are also avoided
