摘　　要：集成滤波电抗绕组利用特殊的绕组排布设计方式,将滤波装置的空心电抗器集成于变压器绕组,目的在于精简装备个数,减小装备占地面积,在舰船供电系统、城市预装式变电站等谐波含量高,电气装备占地面积有限的场合具有广泛的应用前景。集成滤波电抗绕组作为变压器中的特殊结构绕组与其他正常供电绕组共同构成统一的绕组结构。本文给出了集成滤波电抗绕组变压器的基波电路模型与谐波电路模型,并基于多绕组变压器自感与互感的电压方程,推导各绕组基波电流与谐波电流计算公式;通过基波电流与谐波电流相加得到集成滤波电抗绕组变压器的数学模型。以某300k VA集成滤波电抗绕组舰船整流变压器样机及滤波系统为实验对象,通过对比变压器数学模型计算数据与实测数据,验证了本文数学模型的正确性。The integrated filtering reactor windings transformer is designed by a special winding arrangement design scheme. The air-core reactors of the harmonic filtering devices are integrated as the transformer windings in the transformer. Aiming to reduce the number and the cover area of the equipment, this kind of transformer has a broad prospect of application in the areas of high harmonic content and small covering area, such as the ship power system and the city prefabricated substation. As a special structure winding the integrated filtering reactor winding constitude a complete windings structure with other normal power windings. The paper presents the fundamental circuit model and the harmonic circuit model of the integrated filtering reactor winding transformer, and based on the multi-winding transformer voltage equations the fundamental current and harmonic current formulas of the transformer windings are obtained. The fundamental current and harmonic current of the windings are summed to obtain the mathematical model of the integrated filtering reactor winding transformer. Taking a 300 k VA integrated filtering reactor windings ship rectifier transformer for instance, the mathematical model calculation data and measured data are compared to prove the correctness of the mathematical model in this paper.
