Intelligent drying device for transformer

An intelligent drying device for a transformer, wherein the transformer has an intake state and an exhaust state, the intelligent drying device comprising:

• an air dehydrating device being in air communication with the transformer and including a device body, a sensor, and a heater, the device body having a desiccant, and the sensor and the heater being disposed on the device body;
• and
• a control device connected to the air dehydrating device and including a display module;
• wherein, when the transformer is in the intake state, the air dehydrating device is configured to remove moisture from an air stream by the desiccant and obtain air humidity data by the sensor over a predetermined time period;
• wherein, when the transformer is in the exhaust state, the air dehydrating device is configured to remove moisture from the desiccant by the heater;
• wherein the control device is configured to determine a humidity status level to be displayed on the display module according to the air humidity data of the predetermined time period;
• wherein the air humidity data includes an average value of daily average humidity values of all days within the predetermined time period, and the humidity status level is divided into four levels;
• wherein, when the average value is less than 30%, the humidity status level to be displayed on the display module is a first level among the four levels;
• wherein, when the average value is greater than or equal to 30% and less than or equal to 45%, the humidity status level to be displayed on the display module is a second level among the four levels;
• wherein, when the average value is greater than 45% and less than or equal to 60%, the humidity status level to be displayed on the display module is a third level among the four levels;
• wherein, when the average value is greater than 60%, the humidity status level to be displayed on the display module is a fourth level among the four levels;
• wherein, when the sensor obtains a temperature value higher than a predetermined temperature value, the control device is configured to display a first fault symbol on the display module;
• wherein, when the sensor obtains a humidity value higher than a predetermined humidity value, the control device is configured to display a second fault symbol on the display module;
• and
• wherein the control device further includes a circuit board module, and the circuit board module includes a current detection unit;
• wherein, when the current detection unit obtains a current value lower than a predetermined current value, the control device is configured to display a third fault symbol on the display module.
