Description

摻酯油之電器、摻酯油之變壓器及含於酯油中之醛化合物的分析方法 Method for analyzing an appliance containing an ester oil, a transformer containing an ester oil, and an aldehyde compound contained in an ester oil

本發明,係有關在絕緣、冷卻媒體方面使用酯油的摻酯油之電器、摻酯油之變壓器、及使用於摻酯油之電器的酯油中的醛化合物的測定方法。 The present invention relates to an apparatus for measuring an aldehyde compound in an ester oil using an ester oil for an insulating or cooling medium, a transformer incorporating an ester oil, and an ester oil used in an appliance containing an ester oil.

歷來,在作為使用絕緣、冷卻媒體的電器的變壓器的絕緣、冷卻媒體方面泛用礦油。近年來,基於對於環境問題的關心的高漲,在變壓器的絕緣、冷卻媒體方面遂漸代替此礦油而應用生物可分解性高的植物油、或由脂肪酸與酒精而合成的合成酯油等的酯油。 Mineral oil has been widely used in insulation and cooling media of transformers which are electrical appliances using insulation and cooling media. In recent years, based on the increase in concern for environmental problems, the use of bio-decomposable vegetable oils or synthetic ester oils synthesized from fatty acids and alcohols has been used in the insulation and cooling media of transformers. oil.

在採用礦油下的變壓器,係就日經月累所致的熱劣化使得礦油分解因而生成的一氧化碳、二氧化碳、氫、及甲烷、乙烯等的低分子量的氣體的量、組成進行分析,從而推定礦油的劣化狀態。然而,在絕緣、冷卻媒體方面採用酯油的情況下,與歷來的礦油的情況相比,由於熱劣化所致的分解而生成的低分子量的氣體的量、組成理應不同。為此,正檢討採用酯油下的變壓器的診斷技術。 The transformer under the use of mineral oil analyzes the amount and composition of low-molecular-weight gas such as carbon monoxide, carbon dioxide, hydrogen, and methane, ethylene, etc., which are generated by the thermal deterioration caused by the menstrual cycle. Predict the deterioration state of the mineral oil. However, when ester oil is used for the insulation and the cooling medium, the amount and composition of the low molecular weight gas generated by decomposition due to thermal deterioration are different from those of the conventional mineral oil. To this end, diagnostic techniques using transformers under ester oil are being reviewed.

在日本專利特開2014-211368號公報中,係已揭露一種植物性絕緣油的劣化診斷方法,其係基於測定因植物性絕緣油的分解而產生的脂肪酸的濃度。 In Japanese Laid-Open Patent Publication No. 2014-211368, a method for diagnosing degradation of vegetable insulating oil is disclosed, which is based on measuring the concentration of fatty acid produced by decomposition of vegetable insulating oil.

酯油發生熱劣化時存在於油中的微量的水導致發生水解反應,應會生成構成酯油的脂肪酸及酒精。就因酯油的劣化而生成的構成脂肪酸類進行分析的情況下,脂肪酸類不易揮發,化學結構與酯油接近故難以分離、抽出。 When a small amount of water present in the oil is deteriorated by the ester oil, a hydrolysis reaction occurs, and a fatty acid and alcohol constituting the ester oil are generated. When the constituent fatty acids produced by the deterioration of the ester oil are analyzed, the fatty acids are not easily volatilized, and the chemical structure is close to the ester oil, so that it is difficult to separate and extract.

因此,難以在摻作為絕緣、冷卻媒體的酯油之電器的稼動中簡便地在線就作為因酯油的熱劣化而產生的分解物的脂肪酸及酒精的成分進行分析、定量,因此難以簡便地在線進行摻酯油之電器的預防保全。 Therefore, it is difficult to analyze and quantify the components of fatty acids and alcohol which are decomposition products due to thermal deterioration of ester oil, and it is difficult to easily and easily perform online in the operation of an electric appliance containing an ester oil as an insulating or cooling medium. Preventive maintenance of electrical appliances containing ester oil.

此外,二氧化碳、氫、低分子量的烴等係亦從絕緣紙生成,故存在難以就酯油單獨的劣化狀態以高精度進行診斷如此的課題。 Further, since carbon dioxide, hydrogen, and a low molecular weight hydrocarbon are also generated from the insulating paper, there is a problem that it is difficult to diagnose the ester oil alone in a deteriorated state with high precision.

本發明之目的,在於提供一種摻酯油之電 器、摻酯油之變壓器、及使用於摻酯油之電器的酯油中的醛化合物的測定方法,可就作為摻酯油之電器的絕緣、冷卻媒體而使用的酯油中因熱劣化而生成的低分子量且低沸點的醛化合物,效率佳且簡便地在線進行定量,而使將酯油使用為絕緣、冷卻媒體的電器的預防保全變容易。 The object of the present invention is to provide an electric oil mixed with an ester oil.

Moreover, the oil introduction part 15 for cooling of the cooling core 2 is formed in the center side of the iron core 2.

在實施例1的摻酯油之變壓器,係為了就因作為絕緣、冷卻媒體的酯油6的熱劣化而生成的低分子量且低沸點的醛化合物,透過將酯油6加熱而予以蒸發、氣化為酯油6的液面上的氣相部分,以氣體成分進行分析,因而設置由以下構成所成的分解物分析裝置。 The transformer oil-incorporated transformer of the first embodiment is a low molecular weight and low boiling point aldehyde compound formed by thermal deterioration of the ester oil 6 as an insulating or cooling medium, and is evaporated by heating the ester oil 6 and gas. The gas phase portion on the liquid surface of the ester oil 6 was analyzed by a gas component, and thus a decomposition product analysis device having the following constitution was provided.

亦即,由以下而構成此分解物分析裝置:配 設於槽1的下部而提取槽1的內部的酯油6的配管16a、連接於此配管16a而設置以供於將所提取的酯油6加熱而提取氣體成分用的氣體成分提取容器17、連接於氣體成分提取容器17而設置以將從酯油6所提取的氣體成分從氣體成分提取容器17導引的氣體配管18、連接於此氣體配管18而設置以就從所導引的酯油6提取的氣體成分進行分析的氣體分析裝置19。 That is, the decomposition analysis device is constituted by the following: a pipe 16a for extracting the ester oil 6 inside the tank 1 and a pipe 16a for extracting the inside of the tank 1 and a gas component extracting container 17 for heating the extracted ester oil 6 to extract a gas component, The gas pipe 18 connected to the gas component extraction container 17 and the gas pipe 18 guided from the gas component extraction container 17 are connected to the gas component extraction container 17 and are provided to be connected to the gas pipe 18 so as to be guided from the ester oil. 6 Gas analysis device 19 for analyzing the extracted gas components.

此外,為了將所提取的酯油6中的醛化合物予以蒸發、氣化,在氣體成分提取容器17的外側係設置將酯油6加熱的加熱器20。在此氣體成分提取容器17,透過加熱器20加熱內部的酯油6而將因熱劣化而生成的低分子量且低沸點的醛化合物予以蒸發、氣化的加熱溫度係設定為約80度~150度,優選上設定為約100度~130度。 Further, in order to evaporate and vaporize the aldehyde compound in the extracted ester oil 6, a heater 20 for heating the ester oil 6 is provided outside the gas component extraction container 17. In the gas component extraction container 17, the heating temperature of the low-molecular-weight and low-boiling aldehyde compound which is generated by heating the internal ester oil 6 by the heater 20 to evaporate and vaporize due to thermal deterioration is set to about 80 to 150. The degree is preferably set to be about 100 to 130 degrees.

於圖2示出就酯油的加熱溫度與醛化合物的離子強度的關係進行繪示的特性圖。圖2,係為了分析醛化合物作為劣化的指標,而就提高酯油的溫度的情況下的3聚體、4聚體、5聚體的各成分的蒸發、氣化行為進行調查的結果。觀察係透過產生氣體分析法(EGA-MS:Evolved Gas Analysis-Mass Spectrometry)進行。 Fig. 2 is a characteristic diagram showing the relationship between the heating temperature of the ester oil and the ionic strength of the aldehyde compound. FIG. 2 is a result of investigation of evaporation and gasification behavior of each component of a trimer, a tetramer, and a 5-mer in the case where the temperature of the ester oil is increased as an index of deterioration of the aldehyde compound. The observation system was carried out by means of a gas analysis method (EGA-MS: Evolved Gas Analysis-Mass Spectrometry).

為了提高測定感度,樣品係不使用酯油的熱劣化品,而使用在酯油作為醛化合物添加已醛者。將樣品放入單元後在He環境下予以穩定,以升溫速度10度/分鐘從50度將樣品升溫加熱,將至200度為止連續產生的 氣體導入至質量分析裝置(mass spectrometer)。 In order to improve the sensitivity of the measurement, the sample was not subjected to a thermally deteriorated product of an ester oil, and a compound obtained by adding an aldehyde to an ester oil as an aldehyde compound was used. After the sample is placed in the unit, it is stabilized in the He environment, and the sample is heated from 50 degrees at a heating rate of 10 degrees/min, and continuously generated up to 200 degrees. The gas is introduced to a mass spectrometer.

對應於已醛的特徵離子方面,選擇M/Z值為100者,而測定各離子強度、該總離子流(Total Ion Current)。在He環境下加熱酯油至50~200度,將以點劃線表示M/Z值100的結果示於圖2。 Corresponding to the characteristic ion of the aldehyde, the M/Z value was selected to be 100, and the respective ion intensity and total ion current (Total Ion Current) were measured. The ester oil was heated to 50 to 200 degrees in a He environment, and the result of indicating the M/Z value of 100 by a chain line is shown in Fig. 2.

已醛,係在80~90度程度開始蒸發、氣化,在150度程度放出全部的醛化合物。因此,加熱溫度係可採取80度~150度程度。此外,透過加熱至100度~130度使得可縮短觀察時間,可效率佳地進行測定。 The aldehyde has been evaporated and gasified at 80 to 90 degrees, and all the aldehyde compounds are released at 150 degrees. Therefore, the heating temperature can be about 80 to 150 degrees. In addition, by heating to 100 to 130 degrees, the observation time can be shortened, and the measurement can be performed efficiently.

在示於圖1的摻酯油之變壓器的氣體成分提取容器17方面,係透過以加熱器20加熱收容於氣體成分提取容器17的內部的既定量的酯油6,從而將因酯油6的熱劣化而生成的低分子量且低沸點的醛化合物予以蒸發、氣化為氣體成分提取容器17的內部的酯油面上的氣相部分而予以形成氣體成分。 In the gas component extraction container 17 of the transformer containing the ester oil shown in Fig. 1, the predetermined amount of the ester oil 6 accommodated in the gas component extraction container 17 is heated by the heater 20, thereby causing the ester oil 6 The low molecular weight and low boiling point aldehyde compound formed by thermal deterioration is evaporated and vaporized into a gas phase portion on the surface of the ester oil inside the gas component extraction container 17, and a gas component is formed.

在提取既定量的酯油的手段方面,列舉設置如下的手段:將閥21a一定時間開放從而提取大致固定量的酯油,測定所提取的酯油的重量。 In terms of means for extracting a predetermined amount of ester oil, a means is provided in which the valve 21a is opened for a predetermined period of time to extract a substantially fixed amount of ester oil, and the weight of the extracted ester oil is measured.

透過加熱而蒸發、氣化為氣體成分提取容器17的內部的氣相部分的酯油6的因熱劣化而生成的醛化合物的氣體成分係通過氣體配管18而送至氣體分析裝置19,透過此氣體分析裝置19就因熱劣化而生成的低分子量且低沸點的醛化合物的氣體成分在摻酯油之變壓器的稼動中在線進行分析、定量。 The gas component of the aldehyde compound generated by the thermal deterioration of the ester oil 6 in the gas phase portion of the gas component extraction container 17 which is evaporated and vaporized by heating is sent to the gas analyzer 19 through the gas pipe 18, and is transmitted through the gas pipe 18 The gas analysis device 19 analyzes and quantifies the gas component of the low molecular weight and low boiling point aldehyde compound generated by thermal degradation in the oil of the transformer containing the ester oil.

從氣體成分提取容器對於氣體分析裝置取出醛化合物的手段方面,列舉如流放氮、氦、氬等的惰性氣體。此外,在氣體成分提取容器17的內部設置能以加熱器進行加熱的吸附劑,一旦使蒸發、氣化為氣相部分的醛化合物的氣體成分吸附後,將加熱吸附劑而氣化的醛化合物的氣體成分透過惰性氣體導入至氣體分析裝置,藉此亦可效率佳地取出醛化合物。 From the gas component extraction container, an inert gas such as nitrogen, helium or argon is used as a means for extracting the aldehyde compound from the gas analyzer. Further, an adsorbent capable of heating by a heater is provided inside the gas component extraction container 17, and an aldehyde compound which is vaporized by heating the adsorbent after adsorbing and vaporizing the gas component of the aldehyde compound which is vaporized in the gas phase portion is adsorbed. The gas component is introduced into the gas analyzer through an inert gas, whereby the aldehyde compound can be efficiently extracted.

此外,可透過預先將醛化合物與酯油的引火點、黏度等的劣化狀態的特性賦予關聯,從而進行基於透過氣體分析裝置所得之結果下的劣化的診斷。例如,透過氣體分析結果而得的分析值、所算出的醛化合物的量等成為既定值以上的情況下,判定為酯油發生劣化。進行該診斷的判定裝置,係可採用如下的構成:將氣體分析裝置的測定結果透過信號線發送至監視裝置、記憶部等,就透過氣體分析結果而得的醛化合物的量進行監視。 In addition, it is possible to correlate the characteristics of the deterioration state of the ignition point and the viscosity of the aldehyde compound with the ester oil in advance, thereby performing diagnosis based on the result of the permeation gas analyzer. For example, when the analysis value obtained by the gas analysis result, the amount of the calculated aldehyde compound, or the like is equal to or greater than a predetermined value, it is determined that the ester oil is deteriorated. In the determination device for performing the diagnosis, the measurement result of the gas analysis device is transmitted to the monitoring device, the memory unit, or the like through the signal line, and the amount of the aldehyde compound obtained by the gas analysis result is monitored.

於圖3示出監視裝置的監視器畫面的示意圖。於圖3係示出相對於運轉時間繪示透過氣體分析裝置而得的醛化合物量者、和為了判定酯油的劣化而預先酌情設定的醛化合物量的既定值(虛線)。未發生酯油的劣化時,醛化合物量為以虛線所示之值以下,可透過確認監視器畫面而輕易判定酯油的劣化。 A schematic diagram of the monitor screen of the monitoring device is shown in FIG. FIG. 3 shows a predetermined value (broken line) of the amount of the aldehyde compound which is obtained by the gas analysis device with respect to the operation time, and the amount of the aldehyde compound which is set in advance in order to determine the deterioration of the ester oil. When the deterioration of the ester oil does not occur, the amount of the aldehyde compound is equal to or less than the value indicated by the broken line, and the deterioration of the ester oil can be easily determined by confirming the monitor screen.

判定為酯油發生劣化的情況下,於機器的運轉停止、日常的點檢項目等確認機器的異常的有無,或提取酯油而進一步詳細分析狀態。此外,可依劣化的程度, 而在定期點檢時等停止機器時,交換酯油的一部分或全部從而防範變壓器的故障於未然。 When it is determined that the ester oil is degraded, the presence or absence of abnormality of the machine is checked in the operation of the machine, the daily inspection item, or the like, or the ester oil is extracted to further analyze the state in detail. In addition, depending on the degree of deterioration, In the case of stopping the machine at the time of regular inspection, some or all of the ester oil is exchanged to prevent the failure of the transformer.

此外,診斷到劣化時,設置告知酯油的劣化的手段,使得可使管理變容易。例如,可具備在醛化合物量超過預先設定的既定值的情況下判斷為酯油發生劣化而發出警報的警報裝置等。 Further, when deterioration is diagnosed, means for informing deterioration of the ester oil is provided, so that management can be facilitated. For example, when the amount of the aldehyde compound exceeds a predetermined value set in advance, it is possible to determine an alarm device that causes the ester oil to deteriorate and issue an alarm.

電器的酯油的劣化的確認的頻率,係每週一次、每月一次等。因此可設置按既定期間開始上述劣化的判定的控制裝置。控制裝置,係以既定的週期使泵浦作動而將槽內的酯油取至氣體成分提取容器,同時開始酯油的加熱,且使氣體分析裝置作動。 The frequency of confirmation of deterioration of the ester oil of the electric appliance is once a week, once a month, or the like. Therefore, it is possible to provide a control device that starts the determination of the above deterioration in a predetermined period. The control device activates the pump at a predetermined cycle to take the ester oil in the tank to the gas component extraction vessel, simultaneously starts heating the ester oil, and operates the gas analysis device.

首先,將閥開放,從與槽連接的提取配管提取酯油,在閉閥後使加熱器作動,而加熱被氣體成分提取容器提取固定量的酯油,提取醛化合物。分析醛化合物量後,停止加熱器,淨化殘留於分析裝置等的成分。酯油係成為分解物少者,故可不排出至系統外,而予以返回槽內。此外,所測定的酯油的量係少量(例:50ml),故可廢棄。 First, the valve is opened, the ester oil is extracted from the extraction pipe connected to the tank, and after the valve is closed, the heater is actuated, and the fixed amount of the ester oil is extracted by the gas component extraction container to extract the aldehyde compound. After analyzing the amount of the aldehyde compound, the heater is stopped, and the components remaining in the analysis device and the like are purified. Since the ester oil is a small amount of decomposition products, it can be returned to the tank without being discharged to the outside of the system. Further, the amount of the ester oil to be measured is a small amount (for example, 50 ml), so that it can be discarded.

此外,可透過一台氣體分析裝置、判定裝置,從而監視複數台變壓器等的電器。如上述般劣化的確認的頻率,係每週一次、每月一次等,故可作成相對於一個分析裝置而具有數台電器、配管的切換裝置的電器系統。可從複數台電器,提取個別的酯油,掌握各電器的酯油的劣化的狀態。 In addition, it is possible to monitor electrical appliances such as a plurality of transformers through a gas analysis device and a determination device. Since the frequency of the deterioration as described above is once a week, once a month, or the like, it is possible to provide an electric system having a plurality of electric appliances and piping switching devices with respect to one analysis device. It is possible to extract individual ester oils from a plurality of electric appliances and grasp the state of deterioration of the ester oil of each electric appliance.

使用於一次的判定的酯油,係可為例如1~5ml程度。酯油多時所得的氣體的定量容易,少時酯油的加熱容易。殘留於判定後的成分提取容器的酯油係不具有降低引火點的低分子量的化合物,故可予以返回槽而再利用。此情況下,優選上設置使酯油返回槽的回流配管、使酯油回流至該配管中的泵浦。泵浦,係可透過上述的控制裝置一併加以控制。另外,可採用將判定劣化後的酯油廢棄而依需求補充的構成。 The ester oil used for the primary determination may be, for example, about 1 to 5 ml. The gas obtained by the ester oil is easily quantified, and the heating of the ester oil is easy. The ester oil remaining in the component extraction container after the determination does not have a low molecular weight compound which lowers the ignition point, and therefore can be returned to the tank for reuse. In this case, it is preferable to provide a reflux pipe for returning the ester oil to the tank, and to pump the ester oil back into the pipe. The pump can be controlled by the above control device. Further, it is possible to adopt a configuration in which the ester oil after deterioration is judged to be discarded as needed.

依上述的構成的摻酯油之變壓器時,作成就因在變壓器的運轉中收容於槽1的內部的作為絕緣、冷卻媒體的酯油6的熱劣化而生成而溶解於酯油6中的醛化合物,透過將酯油6加熱而予以蒸發、氣化為酯油6的液面上的氣相部分,而以氣體進行分析,故因酯油6的熱劣化而生成的醛化合物係可效率佳、簡便地在線進行定量,故可達成使摻酯油之變壓器的預防保全變容易。 In the case of the transformer oil-incorporated transformer having the above configuration, the aldehyde which is formed in the ester oil 6 by the thermal deterioration of the ester oil 6 which is an insulating or cooling medium accommodated in the inside of the tank 1 during the operation of the transformer is achieved. The compound is heated and vaporized to obtain a gas phase portion on the liquid surface of the ester oil 6 by heating, and is analyzed by a gas. Therefore, the aldehyde compound formed by thermal deterioration of the ester oil 6 can be efficiently used. By simply performing the quantification online, it is easy to prevent the maintenance of the transformer containing the ester oil.

另外,亦可採取在實施例1的酯油6中添加在摻礦油之變壓器所使用的帶電防止劑等的添加劑。 Further, an additive such as a charge preventing agent used in a transformer of a mineralized oil may be added to the ester oil 6 of the first embodiment.

依本實施例,即可實現一種摻酯油之電器、摻酯油之變壓器、及使用於摻酯油之電器的酯油中的醛化合物的測定方法,可就作為摻酯油之電器的絕緣、冷卻媒體而使用的酯油的因熱劣化而生成的低分子量且低沸點的醛化合物,效率佳且簡便地在線進行定量而可使將酯油使用為絕緣、冷卻媒體的電器的預防保全變容易。 According to the embodiment, the method for measuring an aldehyde compound in an ester oil-containing electric appliance, an ester oil-incorporated transformer, and an ester oil used in an ester oil-containing electric appliance can be realized, which can be used as an insulation of an electric appliance containing an ester oil. The low-molecular-weight and low-boiling aldehyde compound produced by thermal degradation of the ester oil used for cooling the medium is highly efficient and can be easily quantified on-line, so that the ester oil can be used as an insulation and cooling medium. easily.

[實施例2] [Embodiment 2]

接著利用圖4說明作為其他實施例的摻酯油之變壓器的構成。在示於圖4的摻酯油之變壓器的變壓器,係如下構成:氣體成分提取容器17被經由與設置於冷卻器8的下部的冷卻配管9b連通的配管16a而配設。使提取此酯油6的配管16a,設置為在不與槽1直接連通下連通於冷卻配管9b,故可更加簡便地進行配管16a的配設。 Next, the configuration of the transformer containing the ester oil as another embodiment will be described using FIG. The transformer of the transformer with the ester oil shown in Fig. 4 is configured such that the gas component extraction container 17 is disposed via a pipe 16a that communicates with the cooling pipe 9b provided in the lower portion of the cooler 8. The piping 16a for extracting the ester oil 6 is provided so as to communicate with the cooling pipe 9b without directly communicating with the tank 1, so that the piping 16a can be disposed more easily.

在示於圖4的摻酯油之變壓器的構成,係基本的構成與示於圖1的前述的實施例1的摻酯油之變壓器相同,故兩者共通的構成的說明係省略。此外,在使圖4中的摻酯油之變壓器運轉中就因作為絕緣、冷卻媒體的酯油6的熱劣化而生成的低分子量且低沸點的醛化合物在線進行分析、定量的手段亦與示於圖1的前述的實施例1相同,故此處的說明係省略。 The configuration of the transformer containing the ester oil shown in Fig. 4 is basically the same as that of the transformer oil-incorporated transformer of the first embodiment shown in Fig. 1, and therefore the description of the common configuration is omitted. In addition, the means for analyzing and quantifying the low-molecular-weight and low-boiling aldehyde compound produced by thermal deterioration of the ester oil 6 as an insulating or cooling medium during the operation of the transformer oil-mixed oil of FIG. 4 is also shown. The same as in the first embodiment of Fig. 1, the description herein is omitted.

依上述之本實施例,亦如同記載於圖1的前面實施例般可實現一種摻酯油之電器、摻酯油之變壓器、及使用於摻酯油之電器的酯油中的醛化合物的測定方法,可就作為摻酯油之電器的絕緣、冷卻媒體而使用的酯油的因熱劣化而生成的低分子量且低沸點的醛化合物,效率佳且簡便地在線進行定量而可使將酯油使用為絕緣、冷卻媒體的電器的預防保全變容易。 According to the above embodiment, the determination of an aldehyde compound in an ester oil containing an ester oil, a transformer containing an ester oil, and an ester oil used in an appliance containing an ester oil can also be realized as described in the previous embodiment of FIG. In the method, the low-molecular-weight and low-boiling aldehyde compound produced by thermal deterioration of the ester oil used as the insulating or cooling medium of the electric appliance containing the ester oil can be efficiently and easily quantified on-line to obtain the ester oil. It is easy to prevent the use of electrical appliances that are insulated and cooled.

[實施例3] [Example 3]

於圖5示出別的摻酯油之電器之例。本例係使酯油在分析裝置內循環之例。在實施例3,係從槽1主體透過配管16b而編入酯油的提取口,使放出口為冷卻器的下部的冷卻配管9b。供循環用的泵浦係省略。將閥21a、閥21b開放而在分析裝置的配管中使酯油循環,在內部的酯油充分更換為測定時者的時間點將閥關閉,加熱氣體成分提取容器17內的既定量的酯油而測定醛化合物量。測定後的酯油,係僅醛化合物減少,故可將閥開放而予以返回槽。 An example of another appliance incorporating an ester oil is shown in FIG. This example is an example of circulating an ester oil in an analytical device. In the third embodiment, the extraction port of the ester oil is inserted from the main body of the tank 1 through the pipe 16b, and the discharge port is the cooling pipe 9b at the lower portion of the cooler. The pumping system for circulation is omitted. When the valve 21a and the valve 21b are opened, the ester oil is circulated in the piping of the analyzer, and the valve is closed when the internal ester oil is sufficiently replaced with the measurement, and the predetermined amount of the ester oil in the gas component extraction container 17 is heated. The amount of the aldehyde compound was measured. Since the ester oil after the measurement is reduced only by the aldehyde compound, the valve can be opened and returned to the tank.

另外,雖透過下部的冷卻配管9b提取酯油亦無妨,惟為了減輕分析時的加熱,從下部的冷卻配管9a或槽主體之上部提取較有效率。此外,冷卻配管係酯油的流速快,故使放出口為配管使得可產生循環並可省略泵浦的一部分而為優選。 Further, the ester oil may be extracted through the lower cooling pipe 9b. However, in order to reduce the heating during the analysis, it is more efficient to extract from the lower cooling pipe 9a or the upper portion of the tank body. Further, since the flow rate of the cooling pipe-based ester oil is fast, it is preferable that the discharge port is a pipe so that a cycle can be generated and a part of the pump can be omitted.

再者,在實施例3,係附加告知診斷結果的功能。氣體分析裝置的測定結果,係具備電源線24,透過信號線22經由接線盒23,而透過警報信號線25、常時監視信號線26,發送至警報裝置、監視裝置、記憶部等。管理者,係可確認酯油的劣化狀態,進行機器的管理。例如,亦可具備醛化合物的放出量超過預先設定的既定值的情況下判斷為酯油發生劣化而發出警報的警報裝置等。設定值,係調查從予以劣化的酯油而得的測定值、體積電阻率等的酯油的特性而設定。 Furthermore, in the third embodiment, the function of notifying the diagnosis result is added. As a result of the measurement by the gas analyzer, the power supply line 24 is provided, and the transmission signal line 22 passes through the junction box 23, passes through the alarm signal line 25, and the constant-time monitoring signal line 26, and is transmitted to the alarm device, the monitoring device, the memory unit, and the like. The manager can confirm the deterioration state of the ester oil and manage the machine. For example, when the amount of release of the aldehyde compound exceeds a predetermined value set in advance, it may be determined that the ester oil is deteriorated and an alarm device is issued to give an alarm. The set value is set by investigating the characteristics of the ester oil such as the measured value and the volume resistivity obtained from the deteriorated ester oil.

另外,閥、警報裝置等雖可酌情採用公知 者,惟電源停止時閥被開放、警報成為ON者為優選。 In addition, valves, alarm devices, etc., may be used as appropriate. However, it is preferable that the valve is opened and the alarm is turned ON when the power is stopped.

In the measurement stage, the pump and the valve are closed, and the heater is actuated, and a fixed amount of the ester oil is extracted by the gas component extraction container to be heated, and the aldehyde compound is extracted. In the cleaning stage, the heater is stopped, and components, ester oil, and the like remaining in the analysis device and the like are purified and removed. The ester oil after the diagnosis is removed by an aldehyde compound or the like, and is reduced in decomposition amount, so that it can be returned to the tank without being discharged to the outside of the system. Further, the amount of the ester oil to be measured is a small amount (about 1 to 50 ml), so that it can be discarded.

基於在測定時所檢測出的資訊,而進行使管理者獲知酯油的劣化的手段、停止摻酯油之電器的運轉的手段等的控制,使得可效率佳地防止機器的異常,使達成預防保全變可能。 Based on the information detected during the measurement, the controller is notified of the deterioration of the ester oil, the means for stopping the operation of the appliance containing the ester oil, and the like, so that the abnormality of the machine can be prevented efficiently, and the prevention can be achieved. Preservation is possible.

另外,本發明非限定於上述之實施例者,包含各式各樣的變化例。例如,上述之實施例係為了以容易理解的方式說明本發明而詳細說明者,未必限定於具備所說明之全部的構成。此外,可將某實施例之構成的一部分置換成其他實施例之構成,另外亦可對於某實施例之構成加入其他實施例的構成。此外,可對於各實施例之構成的一部分,進行其他構成之追加、刪除、置換。 Further, the present invention is not limited to the above-described embodiments, and includes various modifications.
