What is the working principle of oil dehydration of transformer oil plant?
The dehydration of transformer oil equipment removes the oil’s water by vacuum separation technology. Under high vacuum, the oil evaporates quickly and efficiently, ensuring that the additives inside the oil are not affected by the heating temperature causing secondary damage. The mixture formed by the evaporated water vapor and light hydrocarbons enters the water and gas separation device, the water under precipitation is directly discharged, the water vapor and non-condensable gas enter the vacuum buffer chamber, the cooled water is directly discharged, and the non-condensable gas is discharged by the vacuum pump. After dewatering and degassing, the oil completes a working cycle under the action of the oil pump.
The dielectric strength value of transformer oil is higher after using a double-stage vacuum oil dehydrator plant to dehydrate, degas, de-acidify, and remove free carbon. This vacuum oil dehydration machine can be used for oil filtration, vacuum drying, and oil injection of transformer equipment. The transformer oil dewatering process can effectively filter out 100% of free and 99.9% of dissolved water in the oil while also filtering out 100% of free and 98% of dissolved gas, etc.
How to choose the right transformer oil dehydration process equipment?
1). Power transformer’s voltage level and capacity. Generally speaking, a single-stage vacuum oil purifier machine can be used for dewatering transformers of 110kv-330kv, and a double-stage vacuum oil filtration plant can be used for dewatering transformers of 110kv-500kv.
2). Water content of transformer oil. The high vacuum oil purifier machine adopts reduced pressure separation and a three-dimensional flash rapid evaporation system, effectively filtering out the oil’s free and dissolved water.
3). Other contaminants of transformer oil, The vacuum dehydrator can filter out free and dissolved gases in the oil and harmful substances such as acid value and free carbon.
When choosing the right transformer oil dehydrator plant, you can also consider the following factors:
a).Processing capacity of the equipment: choose the processing capacity of the equipment according to the amount of oil you need to process.
b).Dewatering efficiency of the equipment: The dewatering efficiency of different equipment may vary, and choosing equipment with high dewatering efficiency can complete the dewatering process faster.
c).Brand and quality of the equipment: choosing famous and reliable quality equipment can ensure stable operation and service life.
d).Equipment price: choose the right equipment according to your budget.
e).After-sales service: Choosing a manufacturer that provides good after-sales service can ensure that problems encountered during the use of the equipment can be solved in time.
