Description:

YELOCO Transformer oil filtration machine adopts a double-stage vacuum system and removes water, gas, and impurities from transformer oil thoroughly, increasing and maintaining the oil's dielectric strength. 

Why is transformer oil filtration required?

Why do you need to purify transformer oil? Rather, the first question should be, “Why is it important to have purified oil in a transformer?” Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating, reducing the electrical efficiency and lifetime of the transformer. Similarly, 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. Particle contamination also affects the function of insulating oil. So, the transformer oil filtration machine is required to purify used transformer oil and keep the transformer oil absolutely clean.

Series YH-ZYD Double-stage vacuum transformer oil filtration machine application:

1. It is mainly used for purifying the insulating oil, transformer oil, mutual oil, switch oil, dielectric oil, and so on.
2. Adopts the double-stage vacuum system, which can improve the machine’s working vacuum value, so it can remove the water, gas, and impurities in transformer oil efficiently, increasing and maintaining the oil's dielectric strength, making sure the electric device runs safely.
3. Series YH-ZYD transformer oil filtration process can degas, dehydrate, and filter impurities from transformer oil.
4. Can vacuum fill oil to the transformer, vacuum dry the transformer, and online operation transformer.
5. Designed for processing oils in workshops, in storage tanks, or directly in transformers (energized or de-energized transformers).

Advantages:

1. 1. Adopts the double-stage vacuum system, which can highly improve the machine’s working vacuum value, enable the vacuum limit to reach 5Pa, so it can remove the water, gas, and impurities in transformer oil efficiently, increasing and maintaining the oil's dielectric strength, making sure the electric device running safely.
   2. Multi-stage precision filtration system; mesh filtration combined with molecular adsorption technologies can purify the impurity size to 1 micron.
   3. Special-precision oil pump, low noise, and long usage of life.
   4. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
   5. Double-infrared liquid level sensor; pressure protective system to ensure machine operates easily and safely.
   6. Oil-filled shockproof vacuum gauge and pressure gauge (precise and durable).
   7. Adopts interlocked protective system, which connects oil pump, heater, and liquid level sensor, avoiding blank heating, blank pumping, oil leakage, and electricity leakage. If there is any fault, the machine will turn off automatically. Operation is very safe.
