Mobile Transformer Oil Purification Equipment

Application
Series ZYD Double-Stage  Vacuum Transformer Oil Purification Systems is used for transformer oil dehydration and transf or mer oil dega s ification 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).  T he system is  mounted on a leak proof base and is  installed and operated on a trailer .
Series ZYD  oil purifier is  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.
To meet customers’ special needs, we develops:
ZYD Double Stage Vacuum Insulating Oil Purification Machine
ZYD-A PLC Fully Automatic Transformer Oil Filtration Machine
ZYD-M  Outdoor Mobile Transformer Oil Purification Plant
ZYD-W Fully Enclosed Insulating Oil Purifier Machine
ZYD-S Trailer Open Type Transformer Oil Cleaning Machine
ZYD-Ex Explosion-Proof Vacuum Transformer Oil Purifier
 
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 six vacuum pumps for plant ZYD (2 vacuum pumps of 630 m⊃3;/h, 2 roots pumps of 2000 m ⊃3; /h, 2 roots pumps of 4000 m ⊃3; /h), which can improve the vacuum value highly. Making sure the water-content of the treated oil is less than 1 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. Filter housing for 0.5 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.  Siemens Brand  P.L.C  (Programmable L ogic C ontroller)
2.  Flow Meter
3.  Continuous Online Moisture  in Oil Analyzer Model PTT-001)
4.  Continuous Online Moisture  and Particles in  Oil Monitor (Model PTT-002)
5.  Metallic Weather Proof Enclosure
6.  Double-axles trailer for outdoor use
7. Regeneration system TP BZ with special brand of earth can remove acidity, sludge, other soluble oil decay products and discoloration 

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.
