Abstract

The invention provides a transformer insulating oil chromatographic analysis test sample injection auxiliary device and a transformer insulating oil chromatographic analysis test sample injection auxiliary method. The device comprises a housing and an injector assembly module; the injector assembly module is arranged outside the housing and at the upper part of a sample injection port; the injector assembly module comprise an injector fixing piece, an injector body, a needle head and an injector piston; a needle pushing control mechanism is arranged on the injector piston; the injector body isarranged on the injector fixing piece; a connecting rotating shaft is arranged on the injector fixing piece; the connecting rotating shaft is vertical to the injector and runs through the housing; one end of the connecting rotating shaft is arranged on the injector fixing piece and the other end of the connecting rotating shaft is arranged in the housing; a controller is arranged in the housing;the controller is connected with a power supply module and a relay module; the relay module is connected with a needle inserting and pulling control mechanism and an injector body rotation control mechanism; the relay module is connected with the needle pushing control mechanism and the power supply module; and both the needle inserting and pulling control mechanism and the injector body rotationcontrol mechanism are connected with the connecting rotating shaft.

Description

technical field [0001] The invention belongs to the field of transformer insulating oil chromatographic analysis test, and in particular relates to a transformer insulating oil chromatographic analysis test sampling auxiliary device and method. Background technique [0002] "GB / T 7252-2001 Guidelines for the Analysis and Judgment of Dissolved Gas in Transformer Oil" stipulates that the analysis results of multiple injections of the same gas should be within ±1.5% of the average value (that is, the repeatability is within ±1.5%). within %). In the determination of dissolved gas in transformer oil, the sampling process is a key step, and the sample volume, sampling time and sampling device will all affect the analysis data. [0003] The traditional sampling method in the laboratory is to use a syringe to insert into the injection port to complete the sample injection. In the actual operation process, due to the small diameter of the injection port and the differences in the o...
