Application: Oils inside transformers are mainly for insulating purpose- apart from which they also suppress corona and arcing, and also act as coolants inside the machines. These oils must be maintained absolutely clean and dry in order to achieve and sustain the optimal insulating performance and dielectric strength. Here rises the need for transformer oil purification process. ASSEN ZYD Transformer Oil Treatment Machine is the key to transformer reliability, performance and longevity. Your transformer's insulating oil should be free from moisture, dissolved gases and particles that accumulate as the oil ages. Even some new oils may require treatment to limit these contents to acceptable levels. Features: 1. ZYD machine is equipped with two-stage vacuum pumping speed and advanced dewatering and degassing system. It adopts large-area three-dimensional flashing technology to remove harmful components such as moisture, impurities and hydrocarbons in oil quickly and efficiently, and improve the flash point and dielectric strength of insulating oil. 2. The ZYD equipment is capable of oiling and vacuuming the transformer body during installation or overhaul. 3. ZYD is equipped with a high precise filtration system, which uses high-quality filter elements and multi-stage filtration step-by-step encryption to effectively remove mechanical impurities in the oil and configure automatic detection of filter contamination. 4. ZYD machine is equipped advanced automatic thermostat control system, automatic liquid level control system, automatic defoaming control system, and automatic pressure protection system to ensure high performance operation of the equipment. 5. ZYD machine is user-friendly, low noise, easy to operate, long maintenance interval, low energy consumption and low operating cost. 6. ZYD machine is equipped with interlocking safety protection system, which is connect with oil discharge system, vacuum dehydration system, and heating system to avoid the adverse effects caused by misoperation. ● With filter replacement indicator and filter saturation stop device. ● It is equipped with leakage and overload stop devices to protect the motor. ● With phase sequence, phase loss protection function, sudden shutdown safety control system. Optional Model; 1. Optional P.L.C. intelligent panel control, touch screen operation and dynamic display according to user needs. 2. Optional Online PPM Meter, Optional flow meter with accumulator function. 3. Optional frequency converter, you can adjust the flow according to your needs 4. Optional external port design for transformer vacuum pumping 5. The whole structure can be made into mobile, fixed, fully enclosed, concealed, canvas, open type. 6. Optional three stage high vacuum system for higher vacuum degree work. The oil’s performance after treatment: Moisture PPM ≤3 Gas content % ≤0.01 Impurity size μ ≤1 (no free carbon) Breakdown voltage kV ≥75 IFT dynes/cm ≥40 Acid value mgKOH/g ≤0.03 Dielectric loss factors tgδ(90°C) ≤0.001 Please contact us for more details.
