With the development of technology

electrical automatic equipment such as motors

transformers

and control systems have been widely used in industrial production; Its performance will directly affect the stability and safety of the entire production line. If equipment overheating

electrical short circuits

or mechanical wear and tear are not diagnosed and treated in a timely manner

it can lead to serious production accidents and economic losses. To effectively prevent these problems

this paper will delve into the fault diagnosis and preventive maintenance of electrical automation equipment

with the aim of improving the timeliness and accuracy of fault handling.
