Description:
-- dehydration, degasification, impurities removal, dielectric strength improvement and regeneration
-- removing water, gas, impurities more thoroughly and rapidly.
-- also can be used as an independent vacuum source for vacuum drying and oiling.
 
Features:
1.The plant is delivered ready for operation.
2.Degassing, dehydration and filtering process if various kind of insulation oils in electrical transformers and circuit breakers through put in one or several passes
3. There are two vacuum pumps for plant ZYD (one is the vacuum pump, 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.
4. All oil treatment plants, type ZYD are equipped with an automatic Anti-Foam Control System.
5. The plant is equipped with built-in control and safety devices, which provides for a maximum operating security.
6. Minimised power consumption through optimised degassing (excellent efficiency factor).
7. Standardized filter housing for 1 micron , 5 micron, 20 micron and 80 micron filter cartridges.
8. Automatic supervision of the degree of contamination of the fine filter cartridges
9. ZYD can evacuate the vacuum for the electric equipments separately, such as the transformer. Also it can be used to dry the electric equipment and input the oil into the electric equipment under the vacuum state.
10. 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. So it is a reliable and
high automatically machine.
11. 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.
12. Functions of live line work on-site, vacuum drying and vacuum oiling.
13. Operational can be P.L.C (Programmable Logic Controller). (optional)
14. On-line water content measuring device (optional)
