This machine is mainly use the vacuum separation principle, insulating oil under the vacuum state water vapour, separation and impurities, this machine system only inside a vacuum area it is called single stage vacuum filter oil machine, apply to purify 10 kV, 35 kV and 110 kV, 220 kV transformer with insulating oil, can be used for other power transmission and transformation equipment with insulating oil and all sorts of electrical equipment insulation oil purification processing.
Characteristics:
Water cut than 50 mg/kg, containing gas than 12%, 30 kV quartile breakdown voltage, several times after purification treatment by this machine can reach the following index:
Residual moisture than 5 mg/kg (7 PPm) 0.1% or residual gas
Breakdown voltage of 65 kV quartile nominal filtration accuracy than 1-10 μ m
Technical parameters:
Work than 666 Pa limit vacuum vacuum than 90 Pa work pressure < 0.5 MPa
Work the oil temperature: 45-65 ℃ power: AC380V/frequency 50 Hz three-phase four-wire
