<\/figure><\/div>\n\n\nIn the Atmoseal type conservator, an air cell made of NBR (nitrile butadiene rubber) material is fitted inside the conservator reservoir. <\/p>\n\n\n\n
The silica gel breather is connected to the top of this air cell.<\/p>\n\n\n\n
The oil level in the power transformer rises and falls depending on the deflation and inflation of the air cell. <\/p>\n\n\n\n
When the air cell deflates, the air inside is released through the breather. Conversely, when the cell inflates, outside air enters through the breather. <\/p>\n\n\n\n
This design prevents direct contact between the oil and air, reducing the aging effect of the oil.<\/p>\n\n\n\n
Diaphragm Sealed Conservator<\/h3>\n\n\n\n
The diaphragm sealed conservator uses a diaphragm as a barrier between the transformer oil and atmospheric air. <\/p>\n\n\n\n
This type of tank is designed with two semicircular halves, with a diaphragm held between them. <\/p>\n\n\n\n
As the oil expands, it pushes up the diaphragm, which is indicated by the oil level indicator. <\/p>\n\n\n\n
When the oil level decreases, the diaphragm deflects, allowing atmospheric air to enter through the silica gel breather.<\/p>\n\n\n\n
This type of conservator tank has an advantage over the air cell conservator in preventing insulation failure caused by gas bubbles.<\/p>\n\n\n\n
