In the paper

the pressure impregnation of capacitor vacuum impregnator system is discussed.Pressure impregnation is an important step in capacitor vacuum impregnation.And it has significance as for reducing dielectric failure rate

improving the impregnator quality and providing pressure compensation in lower temperature working environment.Currently

the proficiency of pressure impregnation is not satisfactory.So the topic is focused on how to develop pressure process to meet the requirements.At the same time

the application of inverter control in pressure impregnation process is implemented in order to ensure the process stability and quality of impregnation process.
