110KV Transformer Insulation Oil Purifier With Double Stage Vacuum Pump System

Above 110KV Substation Necessary Maintainance Device - Transformer Oil Purifier with Vacuum System




I. Application of Transformer Oil Purifier
The necessity for transformer oil dehydration and degassing is known for a long time. Transformer oil is used in power equipment where it provides cooling and insulation protection. Over time aggregated moisture, gasses and solid particles can seriously affect these properties. To remove moisture, gasses, and solid particles oil treatment equipment needs to be used.

NSH VFD series is specially designed to purify transformer oil and improve the properties. Its main purpose is to remove moisture, gasses and solid particles from mineral transformer oils as well as natural and synthetic esters.

It is designed as mobile or stationary type, indoor or outdoor type, online and offline operation. Customized options makes VFD model the most popular and practical machine as substation maintenance.


II. Benefits of Transformer Oil Purifier

1. Removes Dissolved Moisture Transformer Oil
2. Reduces combustible gases and oxygen
3. Improves oil dielectric values
4. Improves transformer power factor
5. Extends oil service life
6. Extends transformer service life and reliability

III. Features of Transformer Oil Purifier

1. Unique degassing and moisture removal vacuum technology
2. High precision Filtering System.
3. Powerful double stages Vacuum System.
4. Electrical apparatus Controlling System.
5. High quality components.
6. Diverse design in the structures and functions.
7. Operation on online and offline transformers
8. Most efficient oil processing in its class
9. Works on all types of transformer oils

V. Working Flow of Transformer Oil Purifier

1. The insulating oil is conveyed into the plant by means of pressure difference. Oil will firstly flow through a coarse filter, which can filter out large particles and mechanical impurities from insulating oil.

2. Oil is heated uniformly by electric heater with less specific heat transfer of 1.7w/cm², thus the deterioration of the oil caused by overheating is avoided during this process.

3. The special vacuum tank create a large oil surface and a resulting thin film, where the oil flows track and static water evaporation area were expanded to the largest extent, so that the effect of dehydration and degassing is maximized effectively. The particular double-stage vacuum pump system and pressure-boost technical make vacuum degree in vacuum tank higher than that in common oil purifier plant. Specially-designed oil level controller in the vacuum tank assures a continuous oil flow-through in the plant, thus resulting in an optimised dehydration and degassing of the oil. With the double-stage vacuum oil purifier, the installation period and maintenance period can both be shortened effectively.

4. After degassing and dehydration under vacuum, the oil is conveyed by through the fine filter and out of the plant.

5. Oil Circulation is recommended to achieve better effect of purification and filtration.
