Highly effective vacuum transformer oil regeneration
system/insulation oil reclamation machine/HV oil recondition unit
Series ZYD-III Highly vacuum Transformer oil regeneration machine
is used for overhauling and installing the electric insulating
equipments which can running as energized, such as transformer, oil
switch, and mutual inductor. Also it is especially applied to
regenerate and purify the seriously exhausted insulating oil and
make the oils reach the international standard. As a special
equipment for dehydration, degassing, purification process of
various kinds of insulating oils in electrical transformers and
circuit breakers etc. It is designed on vacuum drying principle,
coalescence and separation technique, accurate fine filtration and
other Zhongnengs'patented technique.
The oil technical data after treatment:
A. Gas content is less than 0.1%
B. Impurity degree is less than 1μm without free carbon
C. Oil dielectric strength (breakdown voltage) is more than 75KV
D. Water content is less than 3 part per million
E. Acidity value is less than 0.01 mgKOH/g
F. Dielectric loss factors at 90°Cis less than 0.001
G. Cleanliness degree is less than NAS 1638 Grade 5
1. Besides the common vacuum oil purifier's function of dewatering,
degassing, and eliminating impurities, this machine can regenerate
the seriously exhausted oil by removing the polarity materials,
such as deep oxides, free carbon in the oil effectively. It can
make the seriously exhausted oil reach the normal index like
anti-oxidation, acid-base water-solubility.
2. Three ways of using: the vacuum dewatering, degassing, removing
impurities system can work independently, so does the regeneration
oil system, and also they can work at the same time.
3. Double-stage, high vacuum pressure and high flow rate that help
remove water, air, gases, solid particulates and other impurities
from oil quickly and efficiently so as to improve the breakdown
voltage of oil and maintain its insulating property.
4.Advanced dehydrating and degassing system that use large area
three-dimension flash distillation technique to remove harmful
composition in the oil, such as water, air and gases.
5. Precise fine multi-stage filtration helps remove mechanical
impurities in oil, high quality filter elements is of corrosion
proof, strong mechanical strength and wear resistance.
6.The machine adopts the double-infrared liquid automatic
controller, sensitive automatic pressure protector and the high
effective equipment for degas, so it is easy to operate.
7. Carbon fiber infrared heating system that can make the oil
contains zero sum of ethyne after treatment.
8. The oil of any grades can be treated on line at the working
9. The Automatic oil purifier model is installed with PLC
(Programmable logical control system) which can control the
equipment automatically to every stage of its process and ensure
its process and ensure its safe operation on site and on line
without human supervision.
10. Can be operated both on-line and off-line.
First, it can improve the voltage and make the every index like
acid value, PH value, of the insulation oil reach the national
standard by removing the water, impurities and gas from the
non-conformable oil. Second, it can improve the insulation oil's
index, completely filtering the polarity materials like free
carbon, deep oxide.
