变压器抗短路能力研究综述
Review of Research on the Short Circuit Withstand Capability of Transformer
摘要
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 pa-per,the short circuit withstand capability of transformer is firstly divided into such two aspects as the electrodynam-icc 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,me-chanical strength,and multi field coupling,as well as various factors affecting short-circuit withstand ability,are dis-cussed.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.关键词
