PROBLEM TO BE SOLVED: To provide a temperature analysis method which can reduce labor and cost required for selection of a material of a trolley wire and a slider which forms a power supply device used for an electric railroad, and a method for manufacturing the power supply device.SOLUTION: A temperature analysis method includes: a step of specifying an overall maximum temperature which is a maximum temperature generated in a predetermined area including a trolley line 100, a slider 110, and a contact point between the trolley line 100 and the slider 110 on the basis of a theoretical formula which indicates a correlation relationship between a contact voltage applied from the trolley line 100 to the slider 110 by the contact point and the overall maximum temperature; a step of specifying a curve which indicates a relationship of temperature distribution to potential distribution generated in the predetermined area on the basis of the contact voltage and the specified overall maximum temperature; and a step of specifying a maximum temperature of an individual member which is a maximum temperature of each of the trolley line 100 and the slider 110 on the basis of a potential at the contact point and the curve.SELECTED DRAWING: Figure 1 |
