【摘要】：本文在介绍了磁控电抗器主体结构、工作原理和运行状态的基础上,利用有限元分析软件ANSYS建立了其三维结构模型并进行了理论分析和数学推导,对其电磁特性、损耗特性、温升特性进行了全面研究。磁控电抗器磁路分布及磁密大小,会直接影响到其损耗。而各项损耗最终会以热效应的方式导致电抗器内部温升,不仅降低其工作效率、浪费电能,还会导致绝缘老化,危害电抗器安全稳定运行。如果能找出导致其损耗增加的因素并在磁路结构上进行新的设计和改进,不仅能够从根本上改善磁控电抗器的运行性能,还能大大减少设计周期和费用,有助于MCR的推广应用,充分发挥其优势。为此,本文研究了影响磁控电抗器铁芯损耗和温升的各种因素,探索了磁路设计的原理和方法。基于此方法,针对磁控电抗器损耗大、温升大的缺点,提出了改善其工作性能的多种新型磁路结构。研究了磁控电抗器磁路结构与性能之间的关系,推导了材料磁导、铁芯直径和小截面面积对其磁路性能的影响机理,给出了一种通用的磁路结构优化设计方法。通过对新型磁控电抗器结构的理论分析、比较论证及仿真验证,表明了该设计可以大大降低磁控电抗器的损耗和温升,满足实际工程的要求。
[Abstract]:Based on the introduction of the main structure, working principle and running state of the magnetron reactor, the three-dimensional structure model of the magnetron reactor is established by using the finite element analysis software ANSYS, and the theoretical analysis and mathematical derivation are carried out, and the electromagnetic characteristics and the loss characteristics are analyzed. The characteristics of temperature rise were studied. Magnetic circuit distribution and magnetic density of magnetic reactor will directly affect its loss. The loss will eventually lead to temperature rise in the reactor by the way of thermal effect, which will not only reduce its working efficiency, waste electricity, but also lead to insulation aging, harm to the safe and stable operation of reactor. If we can find out the factors leading to the increase of loss and make new design and improvement in the structure of magnetic circuit, we can not only fundamentally improve the performance of the magnetron reactor, but also greatly reduce the design cycle and cost, which is helpful to the popularization and application of MCR. Give full play to its advantages. In this paper, the factors affecting the loss and temperature rise of the core of the magnetron reactor are studied, and the principle and method of the magnetic circuit design are explored. Based on this method, a variety of new magnetic circuit structures are proposed to improve the performance of magnetron reactor. The relationship between magnetic circuit structure and performance of magnetically controlled reactor is studied. The influence mechanism of material magnetic conductance, core diameter and small cross section area on magnetic circuit performance is deduced, and a general optimization design method of magnetic circuit structure is presented. Through the theoretical analysis, comparison and simulation of the structure of the new type magnetron reactor, it is shown that the design can greatly reduce the loss and temperature rise of the magnetron reactor and meet the requirements of practical engineering.
