| titleOfInvention | Overheating temperature estimation method in abnormality diagnosis of oil-filled equipment |
| abstract | An object of the present invention is to provide a technique for estimating an overheating temperature in an oil-filled device such as a transformer using an ester insulating oil. In the present invention, H2, CH4, C2H6, C2H4, C3H8, and C3H6 in a vegetable oil-derived fatty acid ester insulating oil are measured by oil-in-gas analysis, and the amount of generation is determined. If the second is CH4 or the first is CH4 and the second is H2 or C2H6, the local superheat temperature is estimated to be 300 ° C., the first is H2 and the second is C2H6 or the first is When C2H6, second is H2, C3H8, C3H6, local overheating temperature is estimated to be 400 ° C., first is C2H4 second is C2H6, or first is C2H6 second is C2H4 If the local superheat temperature is estimated to be 500 ° C. and the first is C2H4, the second is C2H6, the first is C2H4, the second is CH4, or C3H6, the local superheat temperature is 600-7. 0 ℃ to be estimated.
