摘要

干变变压器是一种无油电力变压器，其绕组由高压交联聚乙烯(XLPE)电缆制成。漏抗计算是变压器设计过程中的关键环节。干变变压器的特殊结构使得传统的分析方法无法计算其漏抗。本文提出了一种基于干燥机绕组结构的漏抗解析计算方法。通过三维和二维有限元模型验证了该模型的有效性。

Calculating Dryformer leakage reactance using analytical and finite element methods

Dryformer is an oil-free power transformer that its windings are made of high voltage cross-linked polyethylene (XLPE) cables. Leakage reactance calculation is a key step in transformer design process. Special structure of Dryformer makes conventional analytical methods useless for leakage reactance calculation in this type of transformer. In this paper, an analytical method is proposed for calculating leakage reactance of Dryformer based on its winding structure. The validity of proposed model is verified by means of 3D and 2D finite element models.
