Double-Stage High-Efficiency Vacuum Insulation Oil Purifier

General:

NSH VFD series is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. from the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system. VFD series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.

Operating conditions:

The installation shall be designed to opeartae satifactory at ambient temperatures ranging from -20 deg.C to 55 deg. C

Description:

NSH VFD series utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.

Edges:

To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.

Enhance the value of breakdown voltage greatly.

Easy handling and maintenance.

Inject oil into the transformers

Online work

Lower maintenance and replacement expenses

High efficiency and effectiveness

Small size, light weight, low noise

Various sizes and configurations (shield) available.

Structure:

l Dehydration (Degas) System

The vacuum vessel can enlarge evaporation area efficiently. The heater, being placed on the vacuum vessel, becomes an evaporator. Thus the evaporation area of vacuum vessel is three times more than that of the general vacuum vessel. This innovation can dehydrate and degas effectively and efficiently.

The optimal structure of the dehydration (degas) system enlarges the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization.

l Filtering System(particulate matter removal)

The filtering materials with variable apertures are made of specialized glass fiber. The sizes of the filtering fiber and aperture dwindle gradually in the different filtering stages. The impurities with different particulate sizes are filtered step by step. The capability of removing particulate matters and impurities is improved greatly by this method.

The filtering system has stable and perfect filtering fineness. The filtering fineness has several grades, including 1, 2,3,4,5,6,10 µm etc. Oil β≥1000 after filter.

The filtering system is equipped with reverse rinse and filth device. It improves the effectiveness of filtering and extends the lifetime of filter awfully.
