Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for draining an insulating oil in the disposal step of a transformer by which an insulating oil such as PCB or the like can be effectively drained without danger, and to provide a method for cleaning the inside of an insulation case. SOLUTION: Either a primary terminal 4 or a secondary terminal 5 in a transformer unit 2 is shortcircuited with a conductor 6 having enough a diameter to stand the current flowing in the terminal, and the current is supplied to the other terminal to produce heat in the conductor 6. Thus, the conductor is used as a heat source to heat an insulating oil 3.
