るようになった。 BACKGROUND ART Dielectric formula filter of what capture efficiency of dust is known to be higher than other common filters
The drawback is that clogging is fast because it captures fine dust.
there were. Therefore, in order to compensate for this disadvantage,
A filter material impregnated with highly insulating oil is used.
It became so.

あった。 The present invention is to provide a to the above of the filter medium of the insulating
For a dielectric filter impregnated with high oil, wet filter media
Fine dust that acts as a filter and tries to pass through the filter
Captured with impregnating oil, aggregated and coarsened to form a cake layer
To capture a large amount of dust and extend the clogging life
Can be longer. However, the filter passed through the filter
The problem of oil mist being taken away by clean air
there were.
