Problems solved by technology

Because transformers are surrounded by high-voltage areas, there is a certain degree of danger. Therefore, transformers are generally installed in places far away from residents, and the internal working state and structural state of the transformer cannot be understood before the transformer fails. The monitoring means are very backward
Once a transformer failure occurs, it will inevitably lead to a stop of power supply, which in turn will bring losses to industrial and agricultural production.

Description

technical field [0001] The invention relates to a transformer intelligent control device and its application, which is suitable for monitoring the operating status of American box-type transformers, dry-type transformers and box-type substations. It belongs to the technical field of transformer monitoring equipment. Background technique [0002] At present, the transformers used in the power system include dry-type transformers, combined transformers and American box-type transformers. American box-type transformers are more and more widely used. Since transformers are surrounded by high-voltage areas, there is a certain degree of danger. Therefore, transformers are generally installed in places far away from residents. The monitoring means are very backward. Once a transformer failure occurs, it will inevitably stop power supply, which in turn will bring losses to industrial and agricultural production. Therefore, the means of real-time monitoring of the working state o...
