Allowable temperature for dry-type transformers

Dry-type transformer's operation also has various conditions, its comparison basic is the dry-type transformer's temperature, dry-type transformer needs the suitable ground temperature to be able to carry on the operation. What are the temperatures associated with dry-type transformers? The following is the dry-type transformer related to the various temperature provisions for your reference：

 

　　Generally speaking, the temperature of dry-type transformer should be below 180 °C. 2. When the grade a insulating material is used, the high temperature rise should be less than 60k when the limit working temperature is 105 °C and less than 75k when the grade e insulating material is used at 120 °C 3. When the Class B insulating material is used, the high temperature rise should be less than 80k when the limit working temperature is 130 °C; 4. When the Class C insulating material is used, the high temperature rise should be less than 150K when the limit working temperature is 220 °C. 5. When the Grade F insulating material is used, the high temperature rise should be less than 100k when the limit working temperature is 155 °C; 6. When the grade H insulating material is used, the high temperature rise should be less than 125K when the limit working temperature is 180 °C. The main performance of dry-type transformer temperature and various temperature-related requirements is the above to introduce to you, for dry-type transformer you have any other questions, please contact our small editor to understand it!
