Analysis of the Key Commissioning Points of the Installation and Protection of Power Transformers
This paper mainly analyzes the key technical points of the installation of a power transformer,describes the installation methods of the transformer body,introduces the installation methods of three types of protection de-vices one by one:overcurrent protection,differential protection and gas protection,and also analyzes the specific in-stallation methods of coils and high-voltage bushings near the transformer.After the transformer is installed,this pa-per introduces the preparatory work in the early stage of commissioning,and discusses the key technical points of the commissioning of the transformer under the three states of no load,half load and full load,aiming to provide ref-erence for the installation and commissioning of transformers in the power system.
