How is Transformer Recycling Process? from luis huang's blog

Transformer oil regeneration machine is used in most power equipment because its dielectric properties help in insulting, protecting, and cooling its active parts. Being a mixture of various hydrocarbons transformer oils are of a highly refined nature. In this oil, many bi-products start forming with time due to the oxidation of the oil.

These bi-products can decrease the interfacial tension as well as increase the level of acidity of the oil.In this situation, the dielectric properties of the transformer oil deteriorate due to the formation of sludge in it. So, the oil has to be regenerated by recycling to prevent probable damages to the transformer’s active parts as well as more deterioration of the oil. Transformer oil is recycled and regenerated by using transformer oil recycling equipment. At the inlet of the equipment, a coarse filter is used to filter the oil to remove harmful particles from it before filling it up in the equipment.

When, columns are drained in the tank of saturated oil in the back section of the equipment then the process of reactivation of sorbent starts. Throughout this reactivation process, a vacuum is created and maintained after draining the oil. Then the process of reactivation is started by using certain heating elements on the top of each column. During this process, the sorbent is restored to its original condition by removing impurities from it. This process can be repeated several times until you get reusable sorbent or you have to replace it due to lack of any properties in it.
