Sino-NSH Double Stage Vacuum Transformer Oil Filteration Machine
I. Vacuum Oil Purifier Application
Double-stage transformer oil purifier can quickly remove water, trace water, gas, particles as well as
acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil’s dielectric
strength, effectively making sure electric equipments working safely and normally.
II. Vacuum Oil Purifier Features
1.Double-stage vacuum system, vacuum pump and roots pump, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa
2.Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
3.Double-horizontal film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, dissolved moisture, gas from oil.
4.Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
5.Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
6.Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
7.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.
8.Functions of online work onsite, vacuum drying, vacuum oiling and vacuum filling of transformers and
electrical equipment.
9. Working with oil regeneration device to decolor (remove acid, oxide, free carbon etc) and lower dielectric loss, making the treated oil more limpidity
III. VFD Vacuum Oil Purifier Edges
Comparing with single stage transformer oil purifier, Double stage transformer oil purifier can increase the effectiveness more than three times, more quickly and completely dewater, degas, remove particles to get higher dielectric strength.
This equipment can be used as independent vacuum source with the functions of vacuum filling for transformers and electric plants, vacuum drying and purifying of oil transformers online.
