（技術分野）
本発明は、現在の油中ガス自動分析装置についている脱
気装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a deaerator attached to a current automatic gas-in-oil analyzer.
（従来技術とその問題点）
絶縁油中溶存ガスの分析はガスクロマトグラフのキャリ
アーガスでバブリングさせ、直接ガスクロマトグラフの
カラムに送り込まれ分離定量する。(Prior art and its problems) Gases dissolved in insulating oil are analyzed by bubbling with the carrier gas of a gas chromatograph, and the gas is directly fed into the column of the gas chromatograph for separation and quantification.
ガスクロマトグラフィーでは試料ガスが瞬間にカラムへ
の注入を行わないと、クロフトダラム上でピークが拡が
り、分離の不充分が起る。In gas chromatography, if the sample gas is not instantaneously injected into the column, the peak will broaden on the Croft-Durham, resulting in insufficient separation.
従って試料ガスの脱気も迅速に行う必要がある。Therefore, it is necessary to quickly degas the sample gas.
迅速に脱気を行うには油の薄膜を成形させた方がよいが
、成形油膜は脱気装置内で破壊させないと油がキャリア
ーガスでガスクロマトグラフに送られ、配管、カラムの
汚染が起り分離が不九ケとなり、分析能Ｉがばらつき、
保持時間が一定しなくなり、自動分析が不可能となる。For rapid degassing, it is better to form a thin film of oil, but if the formed oil film is not destroyed in the deaerator, the oil will be sent to the gas chromatograph with carrier gas, contaminating the piping and column, and preventing separation. becomes unstable, and the analytical ability I varies,
Retention time becomes inconsistent and automatic analysis becomes impossible.
（発明の構成）
本発明は、上記の点に鑑みなされた絶縁油中ガス自動分
析装置用の脱気装置で、その構成を以下に説明する。(Structure of the Invention) The present invention is a deaerator for an automatic insulating oil gas analyzer, which was developed in view of the above points, and the structure thereof will be explained below.
絶縁油中溶存ガスの分析は第上図に示す一定の脱気装！
１に採取した油２の底部にガスクロマトグラフのキャリ
アーガス３を吹き込み、バブリング法で脱気・し、上部
より脱気した試料ガス４を直接ガスクロマトグラフのカ
ラム（図示省略）に送り込み分離定量している。For analysis of dissolved gas in insulating oil, use a certain degassing device as shown in the diagram above!
The carrier gas 3 of the gas chromatograph is blown into the bottom of the oil 2 collected in step 1, and it is degassed by bubbling, and the degassed sample gas 4 from the top is directly sent to the column of the gas chromatograph (not shown) for separation and quantification. There is.
脱気を迅速に行うため、脱気装置１において、一定の高
さまで成形した油膜５を上げ、そして成形した油膜の油
が分析装置に入らないように脱気装置ｔｉの上部の一部
をトレース電機を巻いたヒーター６等で３０〜／ＳＯ°
Ｃの温度で加熱し、油膜強度を弱くして油膜を破壊させ
る。In order to quickly perform deaeration, the formed oil film 5 is raised to a certain height in the deaerator 1, and a part of the upper part of the deaerator ti is traced to prevent the oil from the formed oil film from entering the analyzer. 30~/SO° with heater 6 etc. wrapped with electrical equipment
Heating at a temperature of C weakens the strength of the oil film and destroys the oil film.
（実験例）
Ａ、Ｂ、Ｃの３種類の油を用いて油膜の破壊実験を行っ
た結果、全ての油はＳＯａ長の脱気装置の上部まで油膜
が上ったが、トレース電線等のヒーターを弘Ｏαの所に
巻きつけ加熱することにより油膜は破壊した。(Experiment example) As a result of an oil film destruction experiment using three types of oils A, B, and C, an oil film rose to the top of the SOa-length deaerator for all oils, but it The oil film was destroyed by wrapping a heater around Hiro Oα and heating it.
一方、加熱による油膜の破壊温度はＡ油で３０°Ｃ１Ｂ
油でδ００ＣＩＣ油で７．５′Ｏ０Ｃであった。On the other hand, the temperature at which the oil film breaks down due to heating is 30°C1B for oil A.
δ00CIC oil was 7.5'O0C.
しかし、７５０００以上の加熱温度では一部油の分解が
起り、弊害があった。However, at a heating temperature of 75,000 or higher, some of the oil decomposes, which has an adverse effect.
よって最適な加熱条件は脱気装置の７０〜弘ＯＧの箇所
で３０〜／３０°Ｃであることをｍ＝した。Therefore, the optimum heating condition is m = 30-/30°C at the 70-Hiro OG portion of the deaerator.
（発明の効果）
本発明の、油中ガス自動分析装置用の脱気装置は、油膜
の油がガスクロマトグラフに入り込まないので、
ｉｌ＋ 配管や分離カラムの汚染がない。(Effects of the Invention) In the deaerator for an automatic gas-in-oil analyzer of the present invention, oil from an oil film does not enter the gas chromatograph, so there is no contamination of the il+ piping or separation column.
（２） 保持時間（検出成分のピーク位置）が一定とな
り自動分析が可能になった。(2) The retention time (peak position of the detected component) is constant, making automatic analysis possible.
（３）分Ｉｖ度と分析精度が向上した。(3) Improved minute IV degree and analysis accuracy.
等の効果を有し、本発明の装置はバブリングによる油膜
を利用したガス抽出方法には最適のものである。With these effects, the apparatus of the present invention is most suitable for a gas extraction method that utilizes an oil film by bubbling.
