Weather Proof Type High Efficiency Vacuum Dielectric Oil Purifier Machine for Power Plant Maintenance

Weather Proof Type High Efficiency Vacuum Dielectric Oil Purifier Machine for Power Plant Maintenance

Why dewater and degas transformer oil?

water contamination at levels as low as 30 ppm (parts per million) can adversely affect the insulating strength of the oil. With ever-increasing standards for energy efficiency of power distribution transformers, the need to effectively degas will become even more important in the future.

Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating--reducing the electrical efficiency and lifetime of the transformer

Application:
ZYD Series Insulating Oil Vacuum Process Purifying Machine and Transformer Oil Filtration Plant Model ZYD-50(3000LPH) is mainly used for electric power department and industries to deal with various oils such as transformer oil, mutual oil, switch oil, insulating oil, dielectric oil and so on. The machine is especially for purifying the insulation oil in all kinds of large power equipments that are above 110KV, especially for the altitude is over 500-1000 meters. It can remove the free and dissolved water, gas and particles from oil high-efficiently, increasing the pressure force and quality of oil, make sure the electric device running safely. The dielectric value of treated oil is higher than 75~85KV. It is very suitable for the large electric&insulation equipments.

Features:
1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa.
2. Big capacity of moisture ands gas separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength of oil improving greatly.
3. Duplex-Stereo 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, which can purify oil high efficient and make oil highly pure.
5. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
6. Double-infrared liquid level sensor, pressure protective system and foaming elimination system to ensure machine operating 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. It can be operated both online and offline of transformers.
9. Can be used independent device for vacuuming transformers which are above 110KV and can vacuum oil filling for power equipment.
10. Can work online for 150 hours continuously, high reliable and long time running.
11. Can be installed by PLC programming control system to achieve machine working fully automatically.

Advantage:
Series ZYD Insulating Oil Vacuum Process Purifying Machine and Transformer Oil Filtration Plant Model ZYD-50(3000LPH) can quickly remove water, trace water, dissolved gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil's dielectric strength, effectively making sure electric equipments working safely and normally. As the bridge-type vacuum linking system that also can be an independent vacuum power supply, which can vacuuming and oil injecting for electric insulation devices.
 

Technical Parameters:

Oil Purifier Technical Features:

1. Based on the high efficient vacuum oil purifier, Roots vacuum booster system and secondary high vacuum separation system are added, which enable the vacuum limit reaching ≤5Pa.

2. Being able to remove water and gas fast and effectively under high vacuum and high speed operation status, which achieves satisfactory dryness and could bring the breakdown voltage up to 70KW, resulting in an enhanced one-time filtration effect which reduces the oil aging problem existing with ordinary purifiers as caused by repeated heating.

3. Being able to remove the minimal amount of water and various gases in oil, thus ensuring zero acetylene existence. The Purifier can also serve as vacuum oil filler and dryer for transformer.

4. The advanced infrared level automatic control system, interlocking control for pressure protection and power heating system ensures long-term safe and reliable operation.

Use:

To be used for treatment to new oil, imported oil and super HV transformer oil, particularly applicable to 110KV power distribution system and the national grid, shortening the oil treating duration during installation and maintenance of transformer.
