Analysis of Electromagnetic Environment of Distribution Transformer Based on ANSYS Maxwell Modeling

The distribution transformer is the most crucial piece of power equipment in the distribution network system due to the new rural construction's quick expansion and the accompanying rapid development of the supporting distribution network system. While in use, the power distribution transformer will emit electromagnetic radiation. Will electromagnetic radiation have an impact on people's physical and emotional well-being? Is a major worry for the locals. This research uses the ANSYS Maxwell simulation software platform for modeling and simulation of the frame type distribution transformer in order to investigate the effects of electromagnetic radiation produced by the transformer on the surroundings. This essay focuses on the electromagnetic field's variation law in the vicinity of distribution transformers. The simulation may be used to determine the electromagnetic field strength values for each distance range, which can then be compared to the safety limits outlined in national and international standards. The findings demonstrate that, in the case of a distribution transformer operating normally, the electromagnetic field's intensity rapidly declines with distance. The simulation results demonstrate that the electromagnetic field radiation value falls below the safety limit of international standards when the distance from the transformer surpasses 1.5 m. The electromagnetic radiation of distribution transformers examined in this paper can serve as a guide for research on electromagnetic radiation at lower voltage levels and as a theoretical foundation for further distribution network planning and design.
