Research on Transformer Protection Device for 110 kV Substation in Chemical Enterprises
In the 110 kV substation of chemical enterprises,the safe operation of transformers plays a crucial role in the stability of the entire system.Therefore,designing and researching protective devices for transformers is particularly important.This paper briefly introduces the importance of transformer protection,analyzes the intelligent transformer protection devices for startup protection,differential protection,and backup protection,and based on this,designs the software and hardware of the transformer protection devices separately.Through experimental testing,it was found that when there are 36 sampling points,the excitation inrush current of the transformer is very ideal,which can accurately protect the transformer from phase to phase protection and single-phase turn to turn short circuit faults,and is conducive to improving the safety and stability of the power system operation in chemical enterprises.
