[発明の目的]
(産業上の利用分野)
本発明は変圧器の自動監視あるいは診断のための油中ガ

場合はパイプ外側が絶縁油と接し、内側にガスが透過し
そのガスを取り出す。(Prior Art) One of the methods for extracting gas in oil is a method in which insulating oil containing gas is brought into contact with an organic matter permeable membrane, and only the gas in oil is extracted through the permeable membrane. The permeable membrane may be sheet-shaped or pipe-shaped. In the case of a pipe-shaped permeable membrane, the outside of the pipe comes into contact with the insulating oil, and gas permeates inside and is extracted.
透過膜を絶縁油と接触させる方法としては、パイプ形の
場合は単一または束にしたものにフランジを付け、変圧
器の適当な位置に取り付けるか、変圧器から絶縁油を導
いたポットに取り付けるかが考えられる。To bring the permeable membrane into contact with insulating oil, in the case of a pipe, attach a flange to a single or bundled membrane and attach it to an appropriate position on the transformer, or attach it to a pot that leads insulating oil from the transformer. I can think of something.

はドレンバルブを利用して配管することが考えられる。In the case of a sheet-shaped permeable membrane, it is conceivable to attach the permeable membrane to the flange to the side wall of the transformer, or to a pot containing insulating oil. Furthermore, the method of directly attaching to a transformer cannot be applied to a transformer that is already in operation, and a new pot containing insulating oil must be manufactured and installed there. When introducing insulating oil to the pot, it is conceivable to use a drain valve for piping.
新たに新設する変圧器の場合にはいずれの方法をも取る
ことが可能である。In the case of a newly installed transformer, either method can be used.

れていた。(Problem to be solved by the invention) However, when installing it on a transformer, it is necessary to design a transformer with a permeable membrane mounting hole, and when installing it on a pot, it is necessary to design a pot with piping and permeable membrane mounting holes. It's quite complicated. Therefore, it has been desired to more easily attach a permeable membrane for extracting gas in oil to a transformer system.

特徴とする。[Structure of the Invention (Means and Effects for Solving the Problems) In order to achieve the above object, the gas-in-oil extraction device of the present invention has insulating oil inlets and outlets at a plurality of locations, and has a single pipe or a plurality of pipes. The present invention is characterized in that it is comprised of a container that houses a gas-permeable membrane and has two sampling ports from which the permeated gas in oil can be taken out.

is a container in which a single or plural pipe-shaped gas permeable membranes 2 are housed. Insulating oil 3 enters from nozzle 5 and passes through nozzle 4.
Since the liquid is configured to exit from the container l, it stays in the container l for a short time. Note that the insulating oil 3 may be configured to enter through the nozzle 4 and exit through the nozzle 5. 6 and 7 are valves that stop the movement of the insulating oil as necessary, and 9 and 10 are valves that seal the gas accumulated in the permeable membrane 2. 8 is a nozzle that guides the gas to the analyzer.
第2図は第1図の油中ガス抽出装置に絶縁油を導く場合

る。As shown in the figure, one end of the insulating hose Ila is inserted into the nozzle 5 to a desired length, and the other end is inserted into the nozzle 12a of the oil pump 13. Furthermore, one end of an insulating hose Ilb of arbitrary length is inserted into the other nozzle +2b of the pump 13, and the other end is inserted into the flanged nozzle 16. This flange 15a is the transformer insulating oil drain valve 1.
4. Connect to the flange 15b of No.4. An insulating hose (not shown) is inserted into the other nozzle 4 of the extraction device and connected to an outlet of another valve of the transformer (not shown) with an appropriate length.

引き出しセンサまたはガスクロで成分分析を行う。The insulating oil of the transformer passes through the container 1 from the insulating hoses Ilb and Ila and returns to the transformer. By continuing to circulate this insulating oil, the time during which the permeable membrane 2 and new insulating oil are in contact becomes longer, and the gas in the oil accumulates in the permeable membrane 2. After a certain period of time has elapsed, the valve 9 is opened, and the gas inside the permeable membrane 2 is drawn out and its components are analyzed using a sensor or gas chromatography.

。[Effects of the Invention] As explained above, according to the present invention, the permeable membrane and the insulating oil pot are integrated, so that the transformation can be carried out using piping or hoses for circulating oil between the transformer body and the insulating oil pot. All you have to do is connect it to the main body. In addition, the gas extraction part can be separated from the transformer body, and the temperature of the extraction part no longer depends on the temperature of the transformer. It is possible to reduce the change in gas extraction rate with a simple temperature control device.
