Abstract: The electric power is the main factor of the encapsulation cracking of the dry air-core reactor. In order to make the advance warning of the failure of the reactor, it is very important to analyze the electric power distribution of the dry air-core reactor. In this paper,Ansys Maxwell software is used to establish the three-dimensional model of the reactor, and analyze the distribution of the electric power with the model BKGKL-20000/35 under the rated condition and overvoltage conditions by the field-magnetic coupling model. The simulation results show that the maximum value of the electromotive force along the surface distribution is 2649 8×1011 N·m-2, and the overvoltage case is 1024 6×1013 N·m-2. It means that the overvoltage case is more likely to cause the reactor to crack and then cause the accident.

Key words: the electric power, encapsulation cracking, coupling model, distribution
