摘要

配电变压器和非晶铁心变压器的低压、高压绕组中短路电流和漏磁产生的电磁力会引起绕组的平动、破坏和爆炸。因此,对这些力的调查对研究人员和制造商起着重要的作用。最近许多作者使用有限元法来分析电磁力。本文首先为磁矢量势公式建立了一个解析模型,用于计算作用在非晶铁心变压器低压和高压绕组上的电磁力(即轴向和径向力)。然后提出了有限元技术来验证从分析模型得到的结果。将所建立的模型应用于实际问题。

Computation of electromagnetic forces in the windings of amorphous core transformers
: Electromagnetic forces generated by the short circuit current and leakage flux in low-and high-voltage windings of distribution transformers as well as amorphous core transformers will cause the translation, destruction, and explosion of the windings. Thus, the investigation of these forces plays a significant role for researchers and manufacturers. Many authors have recently used the finite element method to analyze electromagnetic forces. In this paper, an analytic model is first developed for magnetic vector potential formulations to compute the electromagnetic forces (i.e., axial and radial forces) acting on the low-and high-voltage windings of an amorphous core transformer. The finite element technique is then presented to validate the results obtained from the analytical model. The developed model is applied to an actual problem.
