Double Stage Vacuum System Transformer Oil Filtration Machine Vacuum Dehydration

Double Stage Vacuum High Efficiency Transformer Oil Filtration Machine,

Tratamiento de Aceite Dieléctrico y Secado de Transformador



I. Application of Transformer Oil Filtration Machine


Series VFD Double-stage-vacuum transformer oil purifier can completely and quickly remove water, trace water, gas, particles as well as other harmful ingredients from oil to improve oil's dielectric strength, effectively making sure electric equipments working safely and normally. Series VFD vacuum oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than 110V substation live line work onsite. Meanwhile, Series VFD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.

II. Benefits of Transformer Oil Filtration Machine


1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa

2. Specially designed vacuum separating chamber, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.

3. Special film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.

4. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies

5. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.

6. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.

7. Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.

8. Special oil pump is suitable for working under high vacuum states, low noise, working reliable.

9. Photoelectric oil foam sensor, automatic eliminating oil foam, making sure vacuum pump working safe and stable.

10. Optional choice of installing moisture sensor to test oil's moisture online.

11. Functions of live line work onsite, vacuum drying and vacuum oiling.


III. Working Flow of Transformer Oil Filtration Machine

1. The insulating oil is conveyed into the plant by means of pressure difference. Oil will firstly flow through a coarse filter, which can filter out large particles and mechanical impurities from insulating oil.

2. Oil is heated uniformly by electric heater with less specific heat transfer of 1.7w/cm², thus the deterioration of the oil caused by overheating is avoided during this process.

3. The special vacuum tank create a large oil surface and a resulting thin film, where the oil flows track and static water evaporation area were expanded to the largest extent, so that the effect of dehydration and degassing is maximized effectively. The particular double-stage vacuum pump system and pressure-boost technical make vacuum degree in vacuum tank higher than that in common oil purifier plant. Specially-designed oil level controller in the vacuum tank assures a continuous oil flow-through in the plant, thus resulting in an optimised dehydration and degassing of the oil. With the double-stage vacuum oil purifier, the installation period and maintenance period can both be shortened effectively.

4. After degassing and dehydration under vacuum, the oil is conveyed by through the fine filter and out of the plant.

5. Oil Circulation is recommended to achieve better effect of purification and filtration.
