Oil Degassing, Thermal Oil Vacuum Drying

Oil Degassing¹Transformer oil degassing is a complex of processes targeted at the removal of water, gasses, and mechanical impurities from the dielectric oil.

There are special oil degassing units used to perform the degassing and vacuumizing processes. The main part of such equipment is a degasifier that consists of two tanks. The vacuum²Vacuum is space devoid of matter. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. in the tanks is created by vacuum pump³A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. system. Oil Degassing takes place when oil flows in thin streams on the surface of Raschig rings⁴Raschig rings are pieces of tube, approximately equal in length and diameter, used in large numbers as a packed bed within columns for distillations and other chemical engineering processes..

Thermal Oil Vacuum Drying⁵Drying is a process of water removal from transformer oil.

The plant is assembled on a frame, supporting the unit’s components: input and output oil pumps, dielectric control cabinet, vacuum chamber, coarse and fine cartridge filters⁶Filter is a device which separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass., vacuum pump and pipelines with valves. The CMM mobile oil unit may be used for: (1) heating electrical equipment that contains dielectric insulating oil⁷Insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. with hot oil; (2) for vacuum drying of transformers⁸A transformer is a static electrical device that transfers electrical energy between two or more circuits.; and (3) for vacuumizing⁹Vacuuming is carried out to remove moisture inside the transformer or to protect it from moisture.. The unit is best suited to facilities that install, repair and service oil filled electric power transformers and other oil filled electrical equipment.
