Investigation on Interaction of Air-Core Reactors Based on Scaling Rules

The heavy use of air-core reactors led to sharp increase of electromagnetic pollution, threating the health of working staff and the normal operation of other electric equipment. Therefore, it becomes important to study the EMI (Electromagnetic Interference) between air-core reactors. Firstly, the small-scale model of the air-core reactor is made based on the scaling rules. Then, the different regular arrangements in the actual installation of air-core reactors are simulated by changing the position of the small-scale models. At last, the MF (Magnetic Field) of air-core reactors is analyzed according to the model. Thus, it is possible to study the MF distribution of different arrangements of air-core reactors by establishing some-small scale models. The study of the paper provides reference for the practical application of air-core reactors in substation.
