Vacuum Oil Filling equiment used mainly in the vacuum oil filling of high-voltage power transformers, high voltage
instrument transformers, capacitors and other high-voltage electric appliances; using PLC control and indurtial
computure to realize man-machine information exchange, the whole process of vacuum drying, Vacuum oil filling,
vacuum pumping and other drying automatic.
There are many methods for dehydration for transformer body under vacuum environment. Each improvement of
drying process is to maximize the efficiency of heating and vacuum. Vacuum and heating is the requirement for
vacuum dry for transformer body. However, heating under normal air pressure will create ageing problem for
body and rusting for iron core ; while Vacuum heating process is very slow as the heat convection and
conduction depend on radiation.
Pressure transformation vacuum dry is more effective and economic method which can solve above problems.
