摘　　要：由于正交可控消弧线圈非线性特性和工作原理的限制,其在工作过程中会产生大量的谐波。文章分析了正交可控消弧线圈的基本工作原理,运用等效磁路的方法提出该线圈的磁路模型。分段结构磁化曲线拟合方式的提出,便于合理地进行正交可控消弧线圈的谐波分析。通过分段磁化曲线给出了正交可控消弧线圈磁饱和度与谐波含量之间的关系;并利用数学模型分析消弧线圈谐波以及谐波公式,有利于消弧线圈谐波抑制,提供纯净、可靠经济的能源。The orthogonal controllable reactor can produce large amount of harmonic, which is caused by its nonlinear characteristic and its working principle. This paper analyzes the orthogonal controllable reactor＇s basic working principle. Using the equivalent magnetic circuit method, it demonstrates the reactor magnetic circuit model. The segmented magnetization curve fitting provides to the orthogonal controllable reactor＇s harmonic analysis reasonably and precisely. At the same time, through this new segmented curve, we illustrate the relation between the magnetic saturation degree and harmonic content. Deduce the orthogonal reactor harmonic mathematically and the harmonic equations which can reduce the reactor harmonic effectively to provide the pure,reliable and economical energy.
