变压器励磁涌流识别现状与发展

Status Quo and Development of Identification on Excitation Surge Current of Transformer

首先分析了励磁涌流的产生和特点,然后阐述了传统和新型励磁涌流识别方法的原理及优缺点,最后对励磁涌流识别方法的发展作出展望,指出单一判据的识别方法已经无法满足现阶段的要求,智能化的多判据综合识别方法将使励磁涌流识别研究有所突破。

Generation and characteristic of excitation surge current was analyzed firstly,then principles,merits and demerits of traditional and new identification methods for excitation surge current were stated,expectation for development direction of identification method for excitation surge current was made at last. It was pointed out that the identification method with single criterion could not meet demand of present stage and intelligent comprehensive identification method with multiple criteria would realize breakthrough of research on identification on excitation surge current.
