China Double-Stage Vacuum Transformer Oil Purification Systems

Double-Stage Vacuum Transformer Oil Purification Systems(ZYD-50)
Series ZYD Double-Stage Vacuum Transformer Oil Purification Systems is used for transformer oil dehydration and transformer oil degasification as well as other electrical insulating liquids such as silicone fluids with modern technique. 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 de-energized transformers). Series ZYD oil purifier can be used as an independent vacuum source with functions of vacuum drying and vacuum oiling.
Regular servicing of transformers with our equipment can substantially improve their lifetime and performance and on top helps to save money.
The new line of. Oil treatment plants Type ZYD", with variable flow capacity, is designed for most economical conditioning and drying of insulating oils. The plants are designed for the following applications:
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)
15. Regeneration system BZ with special brand of earth can remove acidity, sludge, other soluble oil decay products and discoloration (optional)·
Expectations on an effective oil plant for treatment of insulating oil:
· Low moisture content at plant outlet.
· Low gas/air content at plant outlet.
· Elimination of residual gas from the insulation.
· Drying of transformer insulation.
· Easy and failsafe operation.
· On-line measuring and recording of process parameters.
· Flexibility in application (various oil types and oil volumes)
