How Does The Transformer Oil Purifier Work?

How does the transformer oil purifier work?

 

The transformer oil purifier consists of a shell, an adsorbent and a filter. It is a key device to maintain the stability of transformer oil performance. Its operation is based on thermal convection and adsorption purification mechanisms. When the transformer is running, the hot oil enters the oil purifier due to the increase in temperature and the decrease in density. The impurities are adsorbed by the adsorbent and filtered through the filter. The purified oil flows back to the bottom of the oil tank, and the cycle is repeated to maintain the insulation and heat dissipation performance of the oil.
In terms of technological innovation, the oil purifier introduces automatic control and intelligent monitoring technology, automatically filters the oil through PLC control, monitors the oil quality indicators with the help of high-precision sensors, and automatically alarms and adjusts the working mode when the standard is exceeded. Some are also equipped with waste oil recovery devices to practice the green concept.

 

The rated capacity of the transformer is calculated according to the R10 priority coefficient. Common specifications include 3kVA, 5kVA, 10kVA, 15kVA, 20kVA, 25kVA, 30kVA, 40kVA, 50kVA, 80kVA, 100kVA, 125kVA, 160kVA, 200kVA, 250kVA, 315kVA, 400kVA, 500kVA, 630kVA, 800kVA, 1000kVA, 1250kVA, 1600kVA, 2000kVA, 2500kVA, 3150kVA, 4000kVA, 5000kVA, etc. Small-scale electricity consumption scenarios, such as ordinary households and small shops, may use 3-50kVA transformers; medium-sized electricity consumption places such as factories and schools are more common with 100-1000kVA transformers; large substations and large industrial enterprises often require large-capacity transformers of more than 1000kVA. For transformers with different rated capacities, the corresponding oil purifiers will have different parameter designs and selections to ensure the best purification effect of transformer oil.
