摘要
主要论述了影响变压器励磁涌流的因素,以及励磁涌流对变压器三个方面的不良影响,并针对性地提出了四个降低励磁涌流不良影响的措施,其中改善变压器的铁心结构、相关充电保护增加滤波功能和测控装置增加变压器合闸初相角捕捉功能是作者的主要建议。
The paper mostly analyses the influence factors of the magnetic inrush current of the transformer and three aspects bad influence of the magnetic inrush current on the transformer. It puts forward four measures of lowering the bad influence of the encourage magnetic current.Among them, polishing up the structure of transformer＇s core-tank, in the refresh protection adding the function of filter wave, and in the measure and control equipment adding the function of voltage angle catching that close to the transformer are the author＇s primary suggestions.
