【Abstract】 In this paper, an analytic calculation method of magnetic field of dry type air core reactor is presented, the situation of spatial closed loop influenced by magnetic field of reactor and the circulating currents in spatial closed loop are calculated and analyzed. The calculation results are verified by practical tests. The calculation shows that in the designing and installation of air core reactor the circulating currents in the conducting structures in a certain range, which may constitute closed loops such as grounding nets, etc., must be considered, and these structures must be avoided to be arranged near air core reactors.更多还原
