INSPECTION DEVICE OF OIL-IMMERSED TRANSFORMER

摘要

PROBLEM TO BE SOLVED: To provide an inspection device capable of accurately detecting a state of an insulating oil of an oil-immersed transformer. SOLUTION: An oil-immersed transformer 10 includes: a transformer body 14 containing an insulating oil 13 and a transformation section 12 in a tank 11; and a radiator 16 connected to the transformer body 14 via a communication pipe 15 and cooling the insulating oil 13 entering from the transformer body 14 through the communication pipe 15. An inspection device 18 includes a detector 19 to the communication pipe 15 wherein the detector detects a state of the insulating oil 13 flowing through the communication pipe 15.
