Simulation Analysis and Research on Electromagnetic Field of Ultra-Special High Pressure Oil-immersed Reactor

The 1 100 kV UHV shunt reactor has been greatly developed to meet the development of electric industry in China. In this paper, aiming at the simulation analysis of the electromagnetic field and force of the UHV shunt reactor, the finite element 3D model of the oil-immersed reactor is established firstly. Then, the magnetic flux leakage phenomena and magnetic circuit of the reactor core column are analyzed. Finally, the magnetic cloud and electromagnetic force cloud images of each component are calculated. Comparing with the experimental data under actual working conditions, the results show that the error of the simulation is small, which shows the validity of the simulation results of the reactor magnetic field and electromagnetic force. The results provide theoretical support for solving the existing problems of vibration and overheating of the UHV shunt reactor.
