【摘要】 针对市民就居民区附近变配电设备的电磁影响与电力建设部门产生矛盾冲突等问题,采用有限元仿真软件ANSYS Maxwell搭建100kVA三相油浸式配电变压器的实体模型,通过分析高压侧绕组的输入电压、感应电压及低压侧绕组感应电流波形图,侧面验证了模型的正确性、有效性与可靠性。通过理论分析与云图观察相结合的方式,定性研究了变压器内外部磁感应强度分布随相位的变化情况,最后选取变压器两侧的具体场点,定量探究了在这些场点处磁感应强度随距离的衰减规律,得到在3m外的区域变压器对人体影响较小的结论,并结合实际情况,给出了合理的工程建议与日常生活的注意事项。更多还原

【Abstract】 There is a conflict between the electric power construction department and the citizen because of the electromagnetic impact of power transformation and distribution equipment near the residential area.In this research,the finite element simulation software ANSYS Maxwell constructed the entity model of a 100kVA three-phase oil-immersed distribution transformer.By analyzing the input voltage and inductive voltage of the high voltage side wings,and the wave graphs of the low voltage side wings.This study confirmed the correctness,validity,and reliability of the model.For choosing the specific location of the transformer,this study combined the theoretical analysis and cloud image observation,examining the internal and external magnetic induction intensity of the transformer with the phase.This paper quantitatively explored the attenuation law of the magnetic induction intensity with the distance at these field points.In conclusion,the transformer has less impact on the human body in the area 3 meters away.This research also gives reasonable engineering suggestions and matters needing attention in daily life.更多还原
