Production Description:
ZYD-II series Double Stages Vacuum Transformer Oil Purifier (also known as Transformer Oil Filtration Machine or Vacuum Transformer Oil Purifier) can effectively remove moisture, gas, solid impurity from old or new transformer oil, to improve the flash point and dielectric strength value of insulation oil.
ZYD-II can increase the dielectric insulation value more than 35KV at one time. It suits for purifying all kinds of insulation oil, especially suits for purifying transformer oil from 110KV and above 110KV UHV power transmission and distribution projects; also suits purifying of capacitor oil, mutual inductor oil, switch oil, cable oil.
ZYD-II adopts T type vacuum evaporation tank, it separates the evaporation tank and the oil tank, improving evaporation efficiency, prolong the machine lifetime.
Transformer Oil Purifier Working Principle
Water dissolves in transformer oil until the oil internal pressure is balanced . If the pressure, temperature, and saturation which associated with the balance pressure are broken, transformer oil either overflows or absorbs moisture until get to a new balance under new conditions.
For ZYD-II series Vacuum Transformer Oil Purifier, the working vacuum is less than 133pa, it can atomize oil into less than 50um, so it can quickly reduces moisture content to less than 3ppm.
Transformer Oil Purifier Functions
-
Removing Moisture. The final treated oil can achieve less than 3ppm
-
Degassing. The final treated oil can achieve less than ≤0.05%
-
Removing Particles. The final treated oil can achieve1 micrometer
-
Vacuum oil injecting
-
Vacuum drying equipment for transformers
-
Vacuum purification online work, unattended operation.
Technical Features
-
“T ”type double vacuum separation technology, doublestages thin film drying degassing technology, double evaporation area and degassing time.
-
Patented degassing tank: anti-foam structure &Dual electronic foam monitoring system “( key components are from Switzerland), completely eradicating oil entering into vacuum pump.
-
Control System: Optimized design of control interlock protection device, overpressure alarm and protection, phase sequence protection, to ensure whole machine working stably for a long time. Automatic pressure alarm system, automatic overload protection system, automatic constant temperature system, automatic bubble elimination system, automatic protection of blowout prevention and other advanced technologies, to ensure the safe operation of untended operation.
-
Oil atomized particles size is less than 50um, largelyincreasing efficiency for water molecules and gas molecules escaping from oil molecules.
-
Vigorously increase contact area between heater and oil (2w/cm2), reduce the surface temperature of heater, and prevent oil cracking and aging.
-
To install liquid level and temperature protector of heater, prevent instantaneous high temperature of heater.
-
Vacuum pumpcooler preposition, to reduce water get into vacuum pump, reduce the frequency to change vacuum pump oil and extend vacuum pump lifetime.
-
High precision filtering element, fine accuracy is 1 micronoptional: 0.5 micron,β≥
-
Outlet oil pressure protector, to monitor pressure of oil filters all the time,effectively protecting machine and operators.
-
Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak.
-
Adopt the high pressure oil pump,oil transmission stable, low noise, long life
-
Using famous brand high quality components, performance is stable and reliable.
-
Automatic float ball &electronic oil level automatic controlling system, to realize automatic bubble elimination, unattended operation.
-
Easy operation and trouble reminderand trouble shooting tips.
