Abstract

The invention discloses a preparation device and method for a dissolved gas component standard sample in insulating oil, and belongs to the technical field of transformer oil standard oil sample preparation. A preparation method in the prior art has the defects that oil-gas two-phase circulating time is long, gas metering is difficult, gas-liquid two-phase is unstable, and the like. Sample preparation cannot be realized as a preparation method for a standard sample is not disclosed. A cylinder body oscillates up and down as well as left and right through an eccentric assembly, so that quick balance of gas and liquid in the cylinder body is quickened, the structure is convenient for producing and manufacturing, the scheme is feasible, a great number of samples can be prepared in batch, and oil and gas can be balanced within a short time. According to the preparation device and method disclosed by the invention, the processes are reasonable, the scheme is feasible, different algorithm formulas are selected according to different conditions, gas can be accurately metered, and various conditions can be adapted, so that preparation of the dissolved gas component standard sample in oil is more accurate, stable and efficiency, and therefore, production efficiency is improved.

Description

technical field [0001] The invention relates to a preparation device and method for a standard sample of dissolved gas components in insulating oil, and belongs to the technical field of standard oil sample preparation of transformer oil. Background technique [0002] The Chinese patent "A device for calibrating an online chromatograph CN200820152789.2" provides a device for calibrating an on-line chromatograph. Under the action of the circulation pump, the oil and gas are fully mixed in the closed circulation space to realize the preparation of standard insulating oil. [0003] The Chinese patent "Standard oil sample preparation device for checking transformer insulating oil on-line chromatographic monitoring system CN200720096514.7" discloses a standard oil sample preparation device for checking transformer insulating oil on-line chromatographic monitoring system. It is composed of oil, cylinder and its piston driving motor, controller, gas volume flow meter, and solenoid...
