Product Description
Transformer oil vacuum treatment equipment
Description
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.
Features
- 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: ≤3μm
- 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 60±5℃, 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 60±5℃ 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: 0.15MPa±0.01MPa (adjustable).
- Operating temperature of oil: 60±5℃
- Filter fineness: ≤5µm
- Pumping speed of vacuum unit: 2000m3/h
- Pumping speed of oil pump: ≥6m3/h (adjustable as per requirement).
- Usable capacity of vacuum degassing tank: 6~12 m3 (as per the requirement).
