Why purify transformer oil? Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating--reducing the electrical efficiency and lifetime of the transformer. Likewise, 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. particles contamination will also affect the function of insulating oil. So we need to clean used transformer oil.
Application
It is mainly used for purifying the insulating oil in all kinds of large power equipments, which are above 110KV especially for those over 500 meters height area.
According to flow rate of oil treatment, Series ZYD have following models:
ZYD-50,ZYD-100,ZYD-200, ZYD-300, etc. The dimension and weight will be changed with changing the technical specification.
Main Parameter of treated transformer oil by this machine:
Breakdown voltage>70KV
Water content<4PPM
Gas content<0.1%
Particles size<1~5μ without free carbon
Acidity<0.03 mgKOH/g
Features
1. High vacuum: Ultimate vacuum ≤5pa Working vacuum ≤35pa
2. High absorption speed: Absorption speed power ≥333L/S
3. Duplex 3D stereo-evaporation, eliminating the liquid water quickly
4. UK G technology by which the trace water that is show chain, such as dissolved water, can be removed effectively.
5. Distinctive remove impurities system filtering through double FH trapezoidal network and absorption by high polymer without the mechanical power
6. Especially applied to vacuum oiling and drying for power transmission equipments that are over 110KV
7. Can be operated both on-load and off-load
8. This model adopts the PLC full automatic system, operate by touch-screen, with dynamic display and can connect computer to operate. All working processes via the CPU to carry out auto-control by central data processing, and processes kinds of variable feedback data immediately, and then sets instructions.
Advantages
Comparing with the single-stage vacuum oil purifier, this machine dewaters, degases and removes the impurities more quickly, more completely, and makes the oils limiting voltage-withstand value much higher. As the bridge-type vacuum linking system, it is used for filtrating system as well as an independent vacuum power supply to vacuum oiling of power equipment.
