rozkład temperatury - Opis:
- This paper present the mathematical model of thermal spread within stator winding bar in active part as well as the result of the calculation carried out by using this model. This model was created to take advantage of the heat diagram method. It was necessary to split winding bar into parts, inside which temperature is constant. In this way the substitute heat diagram has been obtained according to rules of electrical diagram. The results presented by this paper are applied to two cases of phase distribution inside the calculated slot. First case, the top and bottom bar has the same phase inside slot (slot number 1), for which temperature distribution is computed. Second case, bars belong to different phase (slot number 9). The computations were made for selected type of turbogenerator with indirectly cooled system and radial ventilation ducts. On the basis of running test result of this machine, the thermal model verification was carried out. The calculated temperature of spacer was checked with measurements.
