| Why You Need a ZYB-W-50 Enclosed Transformer Oil Regeneration Machine?

  • The transformer requires clean and dried oil. During its usage, the insulating oil absorbs moisture and gets polluted by sopping fibers, dirty particles, aging products soot, etc.
  • Even unused oil is not clean enough as it may have absorbed moisture from the air or may have got polluted in the barrel it was stored in.
  • The efficiency of the oil as an insulating material is highly reduced as the moisture level increases. Hence transformer oil filtering is an important process that eliminates solid particles, dissolved gases and dissolved water.
  • The electrical properties of the oil can be enhanced by filtering, dehydration and degassing. ZY helps transformers keep in good condition and increase their lifetime.

| Machine’s Main Advantaged Technologies

  • Unique Dehydration (Degas) System: It adopts Duplex 3D stereo evaporation tech which makes the evaporation area three times more than normal evaporation tech. This innovation can dehydrate and degas effectively and efficiently. Meanwhile, we bring the UK G tech from Japan to eliminate the kinds of trace water content and dissolved water thoroughly, so it can increase the breakdown voltage and anti-pressure value enormously, ensuring the transformer oil properties.
  • Elec-controlling System & German 3UG3 Rela: We cooperate with world brands like Siemens, and Schneider, as well as Chinese famous enterprises. The main components of electrical apparatus have proven to be durable and reliable in the past 10 years. Ensure the safety of the controlling system. Equips several protection systems that avoid oil ejection, overload, overvoltage, etc. German 3UG3 relay keeps the machine working safely, and efficiently in any situation such as power off, lack of phase, wrong phase position, etc.
  • Distinctive Filtering System: The filtering system, which is combined with a double FH trapezoidal network with H.P. high molecule polymer material, could remove particles by filtration precision, as well as its material impurities absorbing properties. Distinctively remove various impurities and particles. The filtering system takes the backwash tech, it can clean the filters by backwash, and extends the lifetime of filters awfully.
  • Carbon Fiber Infrared Oil Heating System: Carbon fiber infrared heating system is the most advanced heating tech, the unique heater structure heats the oil uniformly and with stability. it gives the heat quickly(in 3 seconds after power on) and the efficiency of electricity transforming to heat is very high(more than 98%). The oil heating system assures less than 2w/cm2. During the heating process, the deterioration of the oil caused by overheating is avoided. The oil temperature can be adjusted between 0~100℃. The heaters are controlled manually or automatically. The heaters will stop automatically when the temperature reaches a certain degree by the safety protection devices, the heaters also stop when the oil volume of the inlet is insufficient, to avoid damage to the heater. The heater material is good at oxidation resistance at high temperatures and can be used for more than 10 years
  • Cooler, Dielectric Condensation system: The system is composed of a cooler, condenser, water receiver, etc. The vapor and other gas, which evaporated from the vacuum chamber,  first drop in temperature and are rid of moisture in a dielectric condenser whose decalescence medium changes water vapor to liquid water quickly, then are condensed again in cooler.

| Transformer Oil

1. The composition of transformer oil

  • Transformer oil is a kind of mineral oil, refined from petroleum. Transformer oil contains alkanes, naphthenes and aromatic hydrocarbons, which will solidify at low temperatures and decompose and burn at high temperatures. Transformer oil decomposes into methane, ethane, ethylene, acetylene, hydrogen and water at high temperatures. The temperature at the point of accident can be determined after a transformer accident by measuring the ratio of the various gases through chromatography analysis of the transformer oil.

2. The role of transformer oil

  • Insulation role: transformer oil isolates the charged parts of different potentials so that no short circuit is formed.
  • Cooling effect: transformer oil can absorb the heat generated inside the core and winding, and then make the heat emitted through the circulation of oil, to ensure the safe operation of the equipment.
  • Arc extinguishing effect: In oil circuit breakers and transformer on-load regulator switches, the contact switching will generate an arc. Transformer oil can decompose a large amount of gas under the high temperature of the arc, resulting in greater pressure, thus improving the interrupting performance of the medium, so that the arc is quickly extinguished.

3. The basic requirements of transformer oil

  • The basic requirements of electrical equipment for transformer oil are a high dielectric strength, to adapt to different working voltages a low viscosity to meet the needs of circulating convection and heat transfer. have a high flash point temperature to meet the requirements of fire protection. It has enough low-temperature performance to resist the low-temperature environment that the equipment may encounter and has good oxidation resistance to ensure that the oil has a long service life.

4. Expansion of transformer oil

  • Transformer oil will be thermal expansion and contraction, its volume change rate is seven-ten thousandths. Every time the temperature changes, the volume increases or decreases by seven ten thousandths.
  • When the transformer is running, the top oil temperature is allowed to rise to 55℃. From this, the volume change of transformer oil can be calculated as 7*55/10000 = 3.85%.
  • Oil-immersed transformers need to have 5% to 8% space for transformer oil to expand and contract thermally.
  • Oil-immersed transformers use oil storage cabinets (oil pillow), corrugated oil tanks and corrugated oil storage cabinets as the space for thermal expansion and contraction.
