摘要

当短路电流流过变压器时，它会在变压器中产生与电流平方成正比的电动力，这可能导致变压器绕组的变形，甚至可能损坏。因此变压器必须具备一定的抵抗短路的能力。文中首先将变压器抗短路能力分为短路电流在变压器绕组中产生的电动力及与之相对抗的机械强度两个方面，并对这两方面原理进行了详细阐述；其次探讨了电动力、机械强度和多场耦合的研究进展，以及影响抗短路能力的各种因素；再者表明变压器抗短路能力研究的展望，这对变压器抗短路能力有重要意义，最后做出总结。

Abstract

The short circuti current

in case of flowing through a transformer

will generate an electro dynamic force proportional to the square of the current in the transformer

which may cause deformation or even damage to the transformer winding. Therefore

the transformer must possess the ability to withstand short-circuit current. In this paper

the short circuit withstand capability of transformer is firstly divided into such two aspects as the electrodynamicc force generated by the short circuit current in the transformer winding

and the mechanical strength that opposes it. The principles of those two aspects are described in detail. Then

the research progress on electrodynamics

mechanical strength

and multi field coupling

as well as various factors affecting short-circuit withstand ability

are discussed. Furthermore

the prospect of research on the short-circuit withstand ability of transformer is presented

which is of great significance for the short-circuit withstand ability of transformers. Finally

a summary is provided.
