Field of the Invention The present invention relates to an apparatus for quickly producing a standard oil for a calibration curve of an analyzer (gas chromatograph) for performing internal diagnosis of a transformer. 2. Description of the Related Art A serious trouble can be prevented beforehand by measuring a gas component in insulating oil inside a transformer. At this time, a gas chromatograph is generally used as a measuring device. . Conventionally, a standard oil obtained by dissolving a standard gas in an insulating oil has been used to calibrate the gas chromatograph.
It takes 5 to 6 hours for degassing work to remove gas components such as oxygen and nitrogen from new insulating oil, and 5 to 6 hours to dissolve standard gas in degassed insulating oil. , Work efficiency was poor. SUMMARY OF THE INVENTION The present invention has been made in view of the fact that it took a long time to prepare a standard oil and that there was a problem that the cost was high if made outside. There is a technical problem of providing a device that can produce standard oil in a short time without human intervention. [0005] In order to achieve the above object, according to the present invention, when the insulating oil is injected into the degassing container, the tank is evacuated and then injected to foam the insulating oil. After confirming that the amount of oxygen, nitrogen, and carbon dioxide dissolved in the oil rapidly decreased, the method of injecting the insulating oil into the degassing container was adopted. [0006] The development of a special syringe having a pair of gas reservoirs arranged in a cylindrical direction so that the added standard gas gathers at a predetermined location improves the stirring efficiency of the standard gas injected into the syringe and improves the dissolution rate into insulating oil. Became faster. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a standard oil producing apparatus for a gas-in-oil-transformer analyzing apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a special injection cylinder which is a melting part of a standard oil producing apparatus for a gas analyzer in a transformer according to the present invention. FIG. 2 shows the configuration of a standard oil producing apparatus for a gas analyzer in a transformer according to the present invention. FIG. 3 shows the flow of operation of the standard oil producing apparatus for a gas-in-oil-transformer analyzer according to the present invention. The standard oil producing apparatus for a gas-in-oil-transformer analyzer of this embodiment is a degassing section for degassing dissolved gas in insulating oil and a standard gas of known concentration is dissolved in the degassed insulating oil. It is composed of a melting part. The components and operation of the apparatus will be described separately for the process of collecting the sample oil, the process of degassing, the process of introducing the extracted gas into the analysis unit, and the process of cleaning the system. (1) Sampling process of insulating oil The vacuum pump 5 is turned, the cock 2 is closed, the cock 7 is closed, the needle valve 6 is closed, the cock 4 is opened, and the degassing container 3 is evacuated. Next, the cock 2 is opened and the insulating oil 1 is sucked. Here, the insulating oil is discharged at once in a vacuum,
Preliminary degassing, which is a feature of the present invention, is performed, and most of the dissolved gas in the insulating oil is degassed. When a certain amount of insulating oil enters the degassing container 3,
Close cock 2. (2) Degassing process of insulating oil By rotating the magnetic stirrer 11 (about 2
Time), the stirrer 13 in the degassing container 3 is rotated, and the dissolved gas remaining in the insulating oil is degassed. (3) The cock 4 for transferring the insulating oil is closed, the needle valve 6 is opened, helium is supplied from the needle valve 6, and the inside of the degassing container 3 is returned to normal pressure. Next, the cock 7 is opened, the cock 8 is opened, and the deaerated insulating oil is transferred into the syringe 9. The inside of the syringe barrel 9 is usually installed on the magnetic stirrer 12 in the vertical direction. (4) Dissolution of the standard gas A standard gas having a known concentration is collected with the gas tight syringe 18 and injected through the injection port on the side of the syringe 9. By rotating the magnetic stirrer 12 (about 2 hours), the stirrer 14 of the syringe barrel 9 is rotated to dissolve the injected standard gas in the insulating oil. The injected standard gas accumulates in the gas reservoir below the piston 16 provided by the present invention, and is dissolved by stirring with the stirrer 14. Here, a curved recess is provided in the lower part of the piston 16, so that the injected standard gas is
It is stirred and dissolved in the hollow at the bottom of the piston 16 without causing adsorption or the like around the 16. Note that the concentration of the standard oil can be determined by the following equation. ## EQU1 ## Ci: Theoretical concentration (ppm) (20 ° C.) Cb: Degassed oil blank value (ppm) P: Atmospheric pressure (kPa) V: Degassed oil volume (ml) (20 ° C.) Cg: Component gas concentration (%) T: room temperature (K) Vi: gas injection amount (ml) According to this embodiment, the degassing efficiency and the dissolving efficiency are improved, and the working efficiency is improved. According to the present invention, degassing efficiency and dissolving efficiency are improved, and work efficiency is improved. Further, it is easy to simultaneously mount a plurality of syringes for dissolving the standard gas, and it is possible to further improve the working efficiency.
