Abstract

The invention discloses a degassing sampling device using a mechanical oscillation method. The degassing sampling device is characterized by comprising a blowing gas path, an injector, an oscillation mechanism for carrying out degassing treatment on an insulating oil sample in the injector, and a gas pumping and pushing assembly, and further comprising a quantitative loop and a six-way valve, a switching valve assembly which is connected between the injector and the gas pumping and pushing assembly in series, and a chromatographic analysis connecting gas path which is parallel to the blowing gas path and is connected with the switching valve assembly in series, a reversing valve which is connected between the injector and the switching valve assembly in series, a first solenoid valve and a second solenoid valve. When the degassing sampling device using the mechanical oscillation method disclosed by the invention is used for carrying out a test, complicated manual operation is replaced through automatic operation and test errors caused by a testing process participated by manual work are eliminated, so that the accuracy of a chromatographic analysis result of gas dissolved in insulating oil is further ensured.

Description

technical field [0001] The invention relates to the technical field of insulating oil dissolved gas analysis, in particular to a mechanical oscillation method degassing and sampling device. Background technique [0002] Chromatographic analysis of dissolved gases in insulating oil is a very effective means to judge whether there are latent faults in oil-filled electrical equipment. This technology has been widely used in the power industry at home and abroad. [0003] At present, in the existing technology, domestic electric power laboratories still use chromatographic analysis of dissolved gases in insulating oil at the stage where degassing treatment and chromatographic analysis are completed as two independent processes. The conventional method of degassing treatment is the national standard The mechanical oscillation method in GB / T17623-1998 "Gas Chromatographic Determination of Dissolved Gas Component Content in Insulating Oil". [0004] The above mechanical oscillatio...
