Research and Analysis of Electromagnetic Environment and Protection Scheme of Reactor in Indoor Substation

为研究全户内变电站空心电抗器周围电磁环境特性,在分析三维电磁场理论的基础上,利用有限元仿真软件对单相空心电抗器及电抗器室建立电磁仿真模型。分析空心电抗器周围电磁场分布情况,研究屏蔽装置不同材料和不同厚度方式下整个仿真空间内磁场的变化情况,为改善全户内变电站的电磁环境提供解决方案。

In order to study the electromagnetic environment characteristics around the air-core reactor in indoor substation, based on the analysis of the three-dimensional electromagnetic theory, the electromagnetic simulation model of the single-phase air-core reactor and reactor room is established by using finite element simulation method. The electromagnetic field distribution around the air-core reactor is analyzed. The changes of the magnetic field in the entire simulation space under different materials and different thickness modes are studied, and a solution for improving the electromagnetic environment of the indoor substation is provided.
