| 简介 |
The invention relates to a method for removing corrosive sulfur compounds from a transformer oil. By adding a mixture of rare earths comprising aluminum oxide and aluminum silicate to the transformer oil, and enriching the same with an aqueous solution of soluble metal salts, the corrosive sulfur compounds in transformer oil are neutralized with defined heating and cooling phases. The advantage of said method is that no additional chemical components, such as passivators, are added to the transformer oil. When using a tank for receiving the mixture of the rare earths comprising aluminum oxide and aluminum silicate, the reaction can run in the tank. Any aging products that may be present, and the bonded corrosive sulfur compounds are effectively retained within the tank by means of a filter system, and can be disposed of with the tank. |
