摘要
为提高大型发电机组中大电流互感器的稳定性和可靠性,提高整个电力系统的安全,用ANSYS软件仿真 分析和优化设计15000/5A三相电流互感器的屏蔽绕组电流。仿真结果表明:4段屏蔽绕组并联和2对屏蔽绕组反极性串联二种方案较优。
Large current transformers are mainly used in large scale generators. Its stability and reliability will influence the security of the whole electric power system, so the research to the stability of large current transformers is important. The paper analyzes the current of shielding windings and its optimal design for three-phase 15000/5A current transformers based on ANSYS. The simulation results demonstrate that the two methods of parallel connecting 4 shielding windings and reversed polarity series connecting two pairs of shielding windings are better.
