Research of the Temperature Distribution of the Hollow Conductor in the Evaporative Cooling Hydro-Generators

This article aims to present an effective calculating method for computing the temperature distribution along the length of hollow conductors in the stator bars of evaporative cooling hydro-generators. A kind of partition of flow patterns was adopted and the corresponding convective heat exchange coefficients were calculated according to the different flow patterns. Comparative results show that the calculating temperature distribution is in accord with the experimental measurement to about 10% relative error. On the whole, this calculating model is reliable and can be used in the applied engineering field.

The design of the condenser in the evaporative cooling hydro generators

The condenser is the key component in the evaporative cooling hydro generator. The design of the condenser will directly affect the performance of the whole evaporative cooling system as well as the temperature distribution of the stator bar. So, this paper introduced the method of the arrangement of condensers and the design of the capacity of each single condenser. Especially, under unsymmetrical operating state of the condenser, the influence of which on the cooling effect was analyzed. This will provide the reference for the design of the condenser.
