Product Description

Transformer oil vacuum treatment equipment


This plant has big treating capacity for degassing and filtering insulation oil (or silicon oil) used in super high voltage grade 35kV~1000kV oil-immersed instrument transformers, transformers and capacitors.


  • The plant is equipped with a crude oil tank with adequate volume for storing crude oil; The tank has functions such as metering, max. & min. level controlling, breathing and sewage discharging, etc.
  • Equipped with 2 sets vacuum degassing tanks (6 12tons), which is has functions such as heating, temperature keeping, max. & min. level controlling, etc.
  • Equipped with clean oil storing tank for storing qualified oil after treated.
  • Adopts mutual filtering or single filtering process.
  • Combined with filtering function of vacuum oil filter, increases the filtering result.
  • Equipped with advanced and reliable vacuum system, heating system and measuring & control system to make sure accurate and reliable control.
  • Pipeline layout is reasonable, can be extended to join with vacuum oil-filling system, recycling system and crude oil system outside of factory to become a complete oil system.
  • Processing capacity: 6-12m3/h
  • Performance value of electric insulating oil after treatment:
  • Voltage withstanding: 65kV (under standard electrode)
  • Moisture content: 5ppm
  • Air content: 0.2
  • Filtering fineness: 3m
  • Gas chromatograph: C2H2=0, H2 5ppm, total hydrocarbon 0.4ppm.

Process flow

Preparation phase:

  • Crude oil
  • crude oil tank
  • vacuum oil filter (or plate-frame oil filter)
  • vacuum degassing tank (close the inlet valve when the vacuum degassing tank is full of oil).

Filtering phase:

  • Filtering mode (mutual filtering): vacuum degassing tank
  • filter (vacuum oil filter or other filter) vacuum degassing tank
  • circulated degassing between both vacuum degassing tanks till the sampling is accepted degassed oil tank.

Oil feeding:

Keep the temperature of degassed oil tank within 605, the degassed oil can be transported by oil pump to each oil filling ports after received the oil filling signal from control system.

Other requirements:

The level meter in degassed oil tank can really show the quantity of oil in the tank.

  • Automatic constant temperature, the heating system will control the temperature of oil in degassed oil tank within 605 automatically.
  • Maximum & minimum level meter in each tank has alarm and protection functions.
  • Vacuum system has both auto and manual control modes.
  • Auto and manual control modes, necessary protection, alarm and other functions are available in each phase.
  • The mutual filtering can be transformed automatically, no need operator to watch over the operation, it is safe and reliable.
  • Processing capacity: 6000L (adjustable as per requirement).
  • Operating vacuum: 10-100Pa (adjustable as per the characteristics of product).
  • Ultimate vacuum: 10Pa
  • Pressure of oil filling: 0.15MPa0.01MPa (adjustable).
  • Operating temperature of oil: 605
  • Filter fineness: 5m
  • Pumping speed of vacuum unit: 2000m3/h
  • Pumping speed of oil pump: 6m3/h (adjustable as per requirement).
  • Usable capacity of vacuum degassing tank: 612 m3 (as per the requirement).
