Transformer Flashy Flow Analysis And PC Protect Allocation And Application Study

By analyzing the inrush current differential protection and the basic principles of the transformer differential protection in principle on the shortcomings,how to accurately identify inrush current and internal fault,an analysis of several inrush current methods to identify the strengths and weaknesses.In several cases,mutations in the amount of voltage simulation,based on the amount of voltage sudden inrush current auxiliary criterion.The transformer and the current mechanism,and their impact on the analysis of the causes of harm,and should be discussed on the current transformer protection,on the basis of the corresponding preventive measures.Combination of a variety of transformer preliminary theory,220KV and above large-scale units to improve and optimize the Protection of the program to strengthen the protection of the main functions and improve the reliability of protection,and strengthen the protection of owners,weaken the protection of the back-up a new understanding and Views.
