摘要
浅述了变压器的冲击电流的形成原理,认为主要是由于外部瞬间电流导致磁路趋向饱和,而磁路中的剩磁则加剧了这个饱和程度,最大冲击剩磁通,使这两者同向叠加。列举、分析了常用解决方法,比较了采用基于变压器本身技术工艺解决冲击电流的优势。
Article describes the principle of inrush current.The main cause of the inrush current is the input instant current,which causes magnetic saturation.The remanence reinforces the saturation.These two effects added up at the same direction cause the maximum inrush flux.Here we enumerate and analyze several solutions,illustrate the advantage of solution of LIT.
