摘　　要：10 kV空心电抗器是110 kV和35 kV变电所中重要的工频磁场源。现有的空心电抗器周围工频磁场的计算方法需要电抗器的详细设计数据,而这些数据通常是制造商的技术秘密。笔者采用只需电抗器的铭牌参数和外形尺寸的简化方法分析10 kV空心电抗器周围的工频磁场分布。并用该方法分析电抗器的设计、布置等对周围磁场水平的影响。根据相关标准限值对这种电抗器的工频磁场暴露和干扰影响范围给出了定量的评价,可供变电所设计时参考。The power frequency magnetic field of 10 kV air-core reactor is an important interference source in 10kV and 35 kV substations. A simplified magnetic field evaluation method, which needs only the parameters on nameplate and the outer dimension of the reactor, is proposed in this paper. Based on this method, the impact of reactor design and layout on magnetic field distribution is analysed. The exposure-permission and interference range of such reactor is also estimated. The results can be applied in substation design.
