| Abstract |
This paper presented the characteristic of the thermal transfer in a 50[kVA] cast-resin dry type transformer. The conductivity of the primary winding composed were a plenty of epoxy-resin and a little of Cu was determined by that rating. Otherwise the conductivity of the secondary winding composed of a plenty of Cu and a little of epoxy-resin was determined by comparing the data of analysis using FEM method with those of temperature tests of the prototype cast-resin transformer. Based on the results of the physical characteristics and the simulation by commercial software using FEM method, we established the prototype Model for this test. According to that Model, an analysis on a variation of the hottest spot temperature was discussed as a function of ambient temperatures and velocities in the 50 kVA cast-resin dry type transformer. |
