摘要

PROBLEM TO BE SOLVED: To facilitate preventive maintenance by efficiently and easily quantifying online an aldehyde compound at a low boiling point by low molecular weight generated by thermal deterioration in ester oil which is used as an insulation/cooling medium of an ester oil-filled electric apparatus.SOLUTION: The ester oil-filled electric apparatus comprises: a tank for accommodating an electric device therein; the ester oil of an insulation/cooling medium for insulating and cooling the electric device which is accommodated in the tank; sampling piping for sampling the ester oil in the tank; a gas composition sampling vessel for heating the ester oil which is sampled by the sampling piping, and evaporates and vaporizes a low boiling point aldehyde compound at low molecular weight which is dissolved in the ester oil; and a gas analyzer for analyzing a gas of the aldehyde compound which is sampled by the gas composition sampling vessel.SELECTED DRAWING: Figure 1
