摘要

A method for improving the cooling capacity of a directly air cooling system for a power plant, comprising the steps of:1) a transformer in a cooling system is connected with a voltage of the power supply network and outputs a voltage to an electric motor, so that its operating voltage of 380 – 390 v is achieved;2) a frequency of 40 – 47 hz is of a frequency converter in the cooling system according to the electric motor is emitted;3) a ventilator is driven by the electric motor, which in the case of a voltage of 380 – 390 v and a frequency of 40 – 47 hz operates in accordance with a predetermined speed relation with the aid of a rotational number, generally at least to rotate, and4) Is cooling wind by the rotating fan emitted frontally to a heat radiator.
