Application:

Series ZYD Two Stage Vacuum Transformer Oil Filtration Machine is used for transformer oil dehydration and transformer oil degasification as well as other electrical insulating liquids such as silicone fluids. The ZYD Process is able to increase and maintain the oil's dielectric strength and includes the removal of free and soluble water, free and dissolved air and gases and other particulate matter. The standard ZYD system is designed for processing oils in workshops, in storage tanks or directly in transformers (energized or deenergized transformers). Series ZYD oil purifier can be used as an independent vacuum source with functions of vacuum drying and vacuum oiling.

Features:

1.There are two vacuum pumps for plant ZYD. One is vacuum pump, and the other one is the booster roots pump which can improve the vacuum value highly. Making sure the water-content of the treated oil is less than 3 PPM.
2. ZYD are equipped with an automatic Anti-Foam Control System.
3. The plant is equipped with built-in control and safety system which provides maximum operating security.
4. Minimised power consumption through optimised degassing (excellent efficiency factor).
5. Standardized filter housing for 1 micron , 5 micron, 20 micron and 80 micron filter cartridges.
6. Automatically supervising the degree of contamination of the fine filter cartridges
7. ZYD can evacuate the vacuum of electric equipment separately like transformer. Also it can be used to dry electric equipment and fill the oil into the electric equipment under vacuum.
8. The machine adopts the double-infrared liquid automatic controller, pressure automatic-protector which
can make sure the machine works online for 150 hours continuously without person.
9. 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.
10. Functions of work on-site, vacuum drying and vacuum oiling.
11. Operational can be P.L.C (Programmable Logic Controller). (optional)
12. On-line water content measuring device (optional)
