Power transformers as the core equipment of power transmission and distribution system

to ensure its safe operation has important significance

but the transformer installation is a very complex process

influenced by mixed field installation process and installation workers not familiar with transformer structure.In the transformer installation maintenance process

there will inevitably be some defects

when severe

will cause the transformer tripped

and forced outage maintenance condition.In this paper

the actual site

the typical installations of several accidents are summed up

and the accidents reasons are analyzed

the corresponding improvement measures are developed.It is presented that during installation

maintenance

and repair of the transformers

to advance the organization

technical training

quality control

a clear division of labor

installation and maintenance records.
