【摘要】：铁心电抗器是电网中不可缺少的重要电力设备，起到限流、补偿、滤波等作用。随着CAD技术的不断发展，生产企业人员开始研究如何更加方便、高效的设计铁心电抗器，因此这些技术越来越受到广泛关注。本文从电磁设计、参数化设计及有限元法分析等方面进行串联铁心电抗器研究。论文介绍了铁心电抗器传统电磁设计流程，对铁心电抗器进行了电磁设计计算，利用Visual Basic软件编制铁心电抗器设计软件，得出了铁心电抗器设计计算单。同时，论文利用VB编程语言与Solidworks软件完成铁心电抗器参数化建模，实现参数化装配，并将三维模型导入有限元软件Ansoft中进行稳态磁场分析，得到磁感应强度分布，并结合电感矩阵利用能量法计算铁心电抗器电感值。此外，论文利用Ansys workbench软件，采用计算单中的铜损和铁损作为热源，有限元仿真分析铁心电抗器的温度场，得到其温度分布，，并对比计算温升，确定是否符合绝缘耐温等级的温升要求。论文最后利用伏安法进行铁心电抗器试验，测试得出其电感值，并与所仿真得出的电感值对比，二者比较一致；同时利用红外测温仪测试其额定电流下的各部分温度值，与仿真结果的数值差距不大。论文研究表明，采用有限元分析可以在电感计算和温度分布上代替传统电磁计算，具有一定的工程应用价值。
[Abstract]:Iron core reactor is an important power equipment in power system indispensable, to limit the current, compensation, filtering and so on. With the development of CAD technology, the production of the enterprise personnel began to study how to design more convenient, efficient core reactor, so the technology has attracted more and more attention.
This paper from the electromagnetic design, parametric design and finite element analysis and other aspects of the series iron core reactor. This paper introduces the traditional electromagnetic iron core reactor design process of the electromagnetic iron core reactor design, using Visual Basic software core reactor design software, the design and calculation of the single core reactor. At the same time, the use of VB programming language and Solidworks software to complete the core reactor parametric modeling, parametric assembly, and steady-state magnetic field analysis of 3D model into the finite element software Ansoft, obtained the distribution of magnetic induction intensity, combined with the inductance matrix calculation of core reactor inductance by using energy method. In addition, the use of Ansys workbench software, the calculation of single copper in loss and iron loss as the heat source, temperature field analysis of core reactor finite element simulation, the temperature distribution, and contrast Calculate the temperature rise to determine whether it is in accordance with the temperature rise requirement of the insulated temperature class.
The last part of the paper core reactor test by voltammetry, tests showed that the inductance value, compared with the simulation and the inductance value of the two comparison; at the same time using infrared thermometer to test the temperature of each part of the rated current value, numerical simulation results and the gap is not big. The research shows that, by using the finite element analysis it can replace the traditional electromagnetic calculation in the inductance calculation and temperature distribution, it has certain engineering application value.
