Abstract

PROBLEM TO BE SOLVED: To obtain a diagnostic device by which the partial abnormal heating operation at the inside of a stationary apparatus can be detected sharply by a method wherein an abnormality is diagnosed when the temperature in every point at the inside of the stationary apparatus exceeds a temperature reference value stored in a reference-value storage means on the basis of temperature- distribution-data obtained from a temperature-distribution-data conversion means. SOLUTION: An optical fiber cable 2 has a characteristic that the wavelength distribution of scattered light transmitted at the inside is changed according to a temperature, and it measures the temperature distribution at the inside of a stationary apparatus 1 so as to be transmitted to a temperature-distribution- data conversion part 3 as a signal. The conversion part 3 converts the output signal received from the cable 2 into temperature distribution data. In addition, a diagnosis part 5 compares temperatures in respective points at the inside of the stationary apparatus on the basis of, the temperature distribution data from the conversion part 3, and it judges an abnormality when the temperatures in the respective points exceed the temperature reference value.
