Abstract
The invention discloses an insulating oil storage structure, a detection device and a method of an oil chromatography online monitoring device. The structure includes an oil storage cylinder body, and a piston is arranged in the oil storage cylinder body; The area below the piston inside the cylinder block is the oil sample area, and the oil sample area contains CH 4 、C 2 h 4 、C 2 h 6 、C 2 h 2 、H 2 , CO, CO 2 Gas; the material of the oil storage cylinder is epoxy glass fiber, and the air pressure in the oil storage cylinder is equal to the sum of the air pressure generated by the combined force of the external atmospheric pressure and the gravity of the piston seal ring and the friction resistance of the cylinder wall, so that the content of each component in the oil storage cylinder is stable. The content of dissolved gas in the sealed oil remains constant. The device includes a storage structure, an oil inlet / exhaust port, a detection port, an oil return port, a pump, a tee, a first one-way ball valve, a three-way ball valve, an exhaust pipe, and an oil return pipe. The invention can ensure the content stability of each component in the insulating oil and the effectiveness of the device.
