ZYD Double-Stage Vacuum Transformer Oil Purifier

Application:

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 advanced 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.

To meet customers’ special needs, we develops:

• ZYD Double Stage Vacuum Transformer Oil Purifier
• ZYD-A PLC Fully Automatic Transformer Oil Filtration Equipment
• ZYD-W Fully Enclosed Dielectric Fluids Treatment Equipment
• ZYD-M Outdoor Mobile Transformer Oil Purification Plant

Advantages:

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 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 equipment 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

Optional Features:

1. Fully Automatic Operation Controlled by Siemens Brand P.L.C (Programmable Logic Controller)

2. Flow Meter for auto calculating and recording oil volume and working timefor auto calculating and recording oil volume and working time

3. Continuous Online Moisture in Oil Meter Model PTT-001)

4. Continuous Online Moisture and Particles in Oil Monitor(Model PTT-M)

5. Metallic Weather Proof Enclosure to prevent rain, sun, dust ect.,

6. Single/Double-axles Road worthy Trailer for Outdoor Use

7. Pirani Digital Vacuum Gauge

8. Regeneration system TPBZ with special brand of earth can remove acidity, sludge, other soluble oil decay products and discoloration
