Abstract

The invention provides a method and a device for dissolving a gas in oil. The device comprises a cylinder body, an external pipeline, a circulation pump, a gas charging hole and an oil filling hole, wherein at least one layer of porous partition board is arranged inside the cylinder body; and a bubble refining device is arranged in the gas charging hole to refine gases charged in the cylinder body, so that the gases can be dissolved easily. The cylinder body and the external pipeline are communicated to form a circulation space; the circulation pump provides circulation power; the oil and gascharged in a device are stirred in a circulation space; the oil and the gases are repeatedly compressed and diffuse through the porous partition board; and thus, the gases are uniformly dissolved in the oil to form a standard oil source applicable to an online chromatograph. In addition, the connection parts of the device are provided with sealing devices and adopt circular arc-shaped transition,so the high sealing performance of the whole device is ensured and the dead corners in oil circulation are eliminated.

Description

technical field [0001] The invention relates to a dissolving device and method, in particular to a device and method for uniformly dissolving gas in oil. Background technique [0002] For a long time, dissolved gas analysis (DGA) in insulating oil (including transformer oil and capacitor oil)—gas chromatographic analysis, has been recognized by countries all over the world as an important tool for monitoring and diagnosing early failures of oil-filled power equipment and preventing catastrophic failures. the best method. With the development of condition-based maintenance of power equipment, it is becoming more and more important to use online chromatograph to detect the content of various characteristic gases dissolved in transformer insulating oil, the most basic of which is the test accuracy of online chromatograph Perform real-time evaluations. [0003] In the prior art, the evaluation of the test accuracy of the online chromatograph is usually realized by comparing th...
