摘要:
 提出一种用于计算气隙等效导磁面积的方法: 用有限元法计算自感,将漏感从仿真所得自感中扣除,再结合主电感理论公式反推出气隙等效导磁面积扩大系数。分析了电感参数及 ANSYS计算原理; 结合对比文献论证了本方法的优越性; 实验和仿真验证了该方法的正确性; 定性分析气隙边缘效应的影响因素。研究结果表明: 主要影响因素依次为气隙长度、铁心截面积、铁心相对磁导率,且气隙长度起主导作用; 气隙等效导磁面积扩大系数与气隙长度呈正比,与铁心截面积和相对磁导率呈反比。本方法有效避免了漏电感的影响,所得结论可为铁心电抗器的设计提供参考依据。
Abstract:
 A method is proposed for calculating air-gap equivalent cross-sectional area. The finite elementmethod was used to calculate the self-inductance,
and the leakage-inductance was deducted from the self-inductance simulated. With the main-inductance’ formula,it deduced the air-gap equivalent cross-sec-tional area coefficient’s expression. Different kinds of inductances and ANSYS calculation theory were an-alysed. This method’ s superiority was demonstrated by comparing with the reference. Experiments andsimulations confirm the correctness. Qualitative analysis of influence factors of air-gap edge effect wasmade. Research results showed that main influence factors include air-gap,iron’ s cross-sectional areaand iron’s relative permeability. The air-gap plays a leader role. The relationship between air-gap equiva-lent cross-sectional area coefficient and air-gap is a proportional function,while the relationship is an in-verse proportional function with iron’ s cross-sectional area or iron’ s relative permeability. This methodcan avoid the leakage-inductance’s influence and the results provide some references for designing iron-core reactor.
