PURPOSE:To make it possible to restrain vibration from transmitting from gas separator to gas detector by connecting a coupling between gas separator and gas detector placed on a base through a flexible piping, while its gas detector is not directly supported together with a tansformer but is mounted on the base. CONSTITUTION:Insulating oil 2 is filled in a tank 1 of oil-filled electrical appliance and usually an oil scavenging valve 3 is mounted in it. In addition, a gas separator comprising a gas permeation film 5, a gas reservoir 6, and an oil intake valve 7 is attached at a tip of the oil scavenging valve 3. On the other hand, a gas detector 9 is mounted on a base and is connected with the gas separator 4 through a flexible piping 8. In the case of the gas separator 9, a hexagonal switching solenoid valve 10 is, through a branch pipe 11, connected with the flexible piping 8 attaching to the gas separator 4 and a measuring pipe 12 is fixed in a direction of one way to perform a communication. Thus vibration of a transformer is not transmitted to the gas detector thereby causing its gas detector to maintain and enhance its characteristics.
