れた箱体内に光フアイバーの発光端と受光端を設
け、上記絶縁油中に溶融したガス量を測定する際
、上記光フアイバーを通じて検出ガスの赤外線吸
収波長に対応した一定量の赤外線を上記ガスに照
射し、上記発光端と受光端との間に存在するガス
の赤外線吸収量から特定ガスの種類と濃度を検出
することを特徴とする油中溶融ガス測定装置。 A light-emitting end and a light-receiving end of an optical fiber are provided in a box housing at least the main body of the oil-filled electrical equipment and insulating oil, and when measuring the amount of gas melted in the insulating oil, infrared rays of the detected gas are absorbed through the optical fiber. Melting in oil characterized by irradiating the gas with a certain amount of infrared rays corresponding to the wavelength, and detecting the type and concentration of the specific gas from the amount of infrared absorption of the gas existing between the light emitting end and the light receiving end. Gas measuring device.
