Research on temperature field simulation of dry type air core reactor

Abstract

In this paper, a fluid-thermal coupled finite element model is established to calculate the temperature field of dry type air core reactor, the inner structure of reactor is built both considering the calculation accuracy and computation time. According to simulation results, the detailed temperature distribution regularity are given both with and without the rain cover, and it can be achieved that the highest temperature of inner encapsulations are different after adding rain cover, and higher compared to the situation of without the rain cover. At the same time, the reasons are given by analyzing the fluid field around reactor, which is of guiding significance to the design of reactor.
