A Method of Adding Metal Passivating Agent to Transformer with Electricity

In recent years, incidents of transformer failures caused by oil sulfur corrosion have been frequent. In order to avoid the corrosion of copper wires in transformers caused by corrosive sulfur, State Grid Corporation of China requires special hidden danger management for the addition of metal passivators to Ninas oil transformers. This article introduces a method of using a portable TV/TA refueling machine to add metal passivation agents to transformers during live charging. Introduce the safety measures that should be taken when adding passivating agents to live transformers. Using ZKBY-III portable TV/TA refueling machine to add metal passivation agent to the transformer body with electricity. And introduce the specific operating steps. Vacuum oil replenishment effectively prevents bubbles from injecting into the transformer during the operation process. The entire operation can be independently constructed by the team. It has the advantages of simple operation, strong practicality, safety and reliability.
