Description
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 a method for measuring an aldehyde compound in an ester oil-containing electrical appliance using an ester oil, a transformer incorporating an oil, and an ester oil used in an electrical appliance in which an ester oil is used for insulating and cooling media.
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。 Historically, mineral oil has been widely used in the insulation and cooling media of transformers as electrical appliances using insulation and cooling media. In recent years, based on the increasing concern for environmental issues, transformers have gradually replaced this mineral oil in the insulation and cooling media of transformers, and have applied biodegradable vegetable oils or esters such as synthetic ester oils synthesized from fatty acids and alcohols. 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。 In the case of transformers using mineral oil, the amount and composition of low-molecular-weight gases such as carbon monoxide, carbon dioxide, hydrogen, and methane, ethylene, etc., which are generated by the thermal degradation caused by the degradation of the mineral oil, are analyzed. The state of deterioration of the mineral oil is estimated. However, when an ester oil is used for the insulation and cooling medium, the amount and composition of a low-molecular-weight gas generated by decomposition due to thermal degradation should be different from those of conventional mineral oil. For this reason, 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。 Japanese Patent Laid-Open No. 2014-211368 discloses a method for diagnosing the deterioration of vegetable-based insulating oils, which is based on measuring the concentration of fatty acids generated by the decomposition of vegetable-based insulating oils.

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 the ester oil is thermally degraded, a trace amount of water present in the oil causes a hydrolysis reaction, and fatty acids and alcohols constituting the ester oil should be generated. When the constituent fatty acids generated due to the deterioration of the ester oil are analyzed, the fatty acids are not easily volatile, and the chemical structure is close to the ester oil, so it is difficult to separate and extract them.
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 fatty acid and alcohol components that are decomposed products due to the thermal degradation of the ester oil during the operation of electrical appliances that are mixed with ester oil as an insulating and cooling medium. Preventive maintenance of electrical appliances mixed with 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。 In addition, since carbon dioxide, hydrogen, and low-molecular-weight hydrocarbons are also generated from insulating paper, there is a problem that it is difficult to diagnose the deterioration state of the ester oil alone with high accuracy.
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 purpose of the present invention is to provide a method for measuring an aldehyde compound in an ester oil-containing electrical appliance, an ester oil-containing electrical transformer, and an ester oil-containing electrical appliance. The low-molecular-weight and low-boiling aldehyde compounds in the ester oil used as a cooling medium due to thermal degradation are efficient and easy to quantify on-line, making it easier to prevent and maintain electrical appliances that use the ester oil as an insulating and cooling medium. .
本發明的摻酯油之電器，係具有於內部收容電氣裝置的槽、收容於此槽內且就電氣裝置進行絕緣並冷卻的酯油，其亦具備提取槽內的酯油的酯油的提取配管、加熱以此提取配管所提取的酯油而將溶解於酯油中的低分子量且低沸點的醛化合物予以蒸發氣化的氣體成分提取容器、就以此氣體成分提取容器所提取的醛化合物的氣體進行分析的氣體分析裝置。 The ester oil-doped electric appliance of the present invention has a tank for accommodating an electric device in the interior, an ester oil accommodated in the tank and insulated and cooled for the electric device, and it also includes extraction of the ester oil from the ester oil in the tank. A gas component extraction container that is piping and heated to extract the ester oil extracted from the piping to evaporate and vaporize the low molecular weight and low boiling point aldehyde compounds dissolved in the ester oil, and the aldehyde compounds extracted by this gas component extraction container Gas analysis device for the analysis of gases.

在內側線圈3與外側線圈4之上部係分別設置第一絕緣物11、第二絕緣物12，在內側線圈3與外側線圈4的下部亦分別設置第一絕緣物13、第二絕緣物14。此外，在鐵芯2之中心側係形成冷卻鐵芯2的冷卻用的油導入部15。 A first insulator 11 and a second insulator 12 are respectively provided above the inner coil 3 and an outer coil 4, and a first insulator 13 and a second insulator 14 are respectively provided below the inner coil 3 and the outer coil 4. An oil introduction portion 15 for cooling the cooling core 2 is formed on the center side of the 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 ester oil-doped transformer in Example 1 is a low-molecular-weight, low-boiling-point aldehyde compound generated by thermal degradation of the ester oil 6 as an insulating and cooling medium. The ester oil 6 is heated to evaporate and vaporize the gas. The gas phase portion converted into the ester oil 6 on the liquid surface is analyzed with a gas component. Therefore, a decomposition product analysis device having the following configuration is 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 decomposed matter analysis device is constituted by a pipe 16a disposed in the lower part of the tank 1 to extract the ester oil 6 inside the tank 1, and a pipe 16a connected to the pipe 16a to provide the extracted ester oil 6 A gas component extraction container 17 for heating to extract a gas component, and a gas pipe 18 connected to the gas component extraction container 17 and provided to guide the gas component extracted from the ester oil 6 from the gas component extraction container 17 is connected thereto The gas piping 18 is provided with a gas analysis device 19 that analyzes a gas component extracted from the guided ester oil 6.
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。 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 this gas component extraction container 17, the internal ester oil 6 is heated by a heater 20 to heat and evaporate and vaporize the low-molecular-weight and low-boiling aldehyde compounds generated by thermal degradation. The heating temperature is set to about 80 ° to 150 ° The degree is preferably set to about 100 degrees 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 investigating the evaporation and gasification behavior of each of the trimer, tetramer, and pentamer when the temperature of the ester oil is increased in order to analyze the aldehyde compound as an indicator of deterioration. Observation was performed by Evolved Gas Analysis-Mass Spectrometry (EGA-MS).
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 measurement sensitivity, the sample is not a thermally degraded product of ester oil, but is used in the case where ester oil is added as aldehyde compound. The sample was placed in the cell and stabilized in a He environment. The sample was heated from 50 ° C at a heating rate of 10 ° C / min. The gas continuously generated up to 200 ° C was introduced into 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 ions of hexanal, those with an M / Z value of 100 were selected, and the ionic strength and the total ion current (Total Ion Current) were measured. The ester oil was heated to 50 to 200 degrees in the He environment, and the result of the M / Z value of 100 indicated by a dot-dash 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。 Aldehyde begins to evaporate and vaporize at 80 to 90 degrees, and releases all aldehyde compounds at 150 degrees. Therefore, the heating temperature can be about 80 degrees to 150 degrees. In addition, by heating to 100 to 130 degrees, observation time can be shortened, and 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 with an ester oil shown in FIG. 1, a predetermined amount of the ester oil 6 contained in the gas component extraction container 17 is heated by a heater 20, so that the ester oil 6 The low molecular weight and low boiling point aldehyde compound generated by thermal degradation is evaporated and gasified into a gas phase portion on the ester oil surface inside the gas component extraction container 17 to form a gas component.
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。 As a means for extracting a predetermined amount of ester oil, a means is provided in which a valve 21a is opened for a certain 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 degradation of the ester oil 6 which is vaporized and gasified into the gas phase portion inside the gas component extraction container 17 by heating is sent to the gas analysis device 19 through the gas pipe 18 and transmitted through The gas analysis device 19 analyzes and quantifies the gas components of the low molecular weight and low boiling point aldehyde compounds generated by thermal degradation during the operation of the transformer mixed with 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。 As a means for taking out the aldehyde compound from the gas component extraction container with respect to the gas analysis device, inert gases such as bleed nitrogen, helium, and argon are listed. In addition, an adsorbent capable of being heated by a heater is provided inside the gas component extraction container 17, and once the gas component of the aldehyde compound that has evaporated and vaporized into the gas phase part is adsorbed, the aldehyde compound that is heated to vaporize The gas component is introduced into the gas analysis device through an inert gas, so that the aldehyde compound can be efficiently removed.
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, by associating properties of the aldehyde compound with deterioration characteristics such as the ignition point and viscosity of the ester oil in advance, it is possible to perform deterioration diagnosis based on the results obtained through a gas analysis device. For example, when the analysis value obtained from the gas analysis result, the calculated amount of the aldehyde compound, and the like are equal to or more than a predetermined value, it is determined that the ester oil is degraded. The determination device for performing this diagnosis may have a configuration in which the measurement result of the gas analysis device is transmitted to a monitoring device, a memory section, etc. via a signal line, and the amount of the aldehyde compound obtained through 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 a monitor screen of the monitoring device is shown in FIG. 3. FIG. 3 shows a predetermined value (dashed line) of the amount of aldehyde compound obtained through the gas analysis device with respect to the operating time, and the amount of aldehyde compound set in advance in order to determine the deterioration of the ester oil. When there is no deterioration of the ester oil, the amount of the aldehyde compound is equal to or less than the value indicated by the dotted line, and the deterioration of the ester oil can be easily determined by checking 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。 If it is determined that the ester oil is degraded, confirm the presence or absence of the abnormality of the machine by stopping the operation of the machine, daily inspection items, etc., or extracting the ester oil to further analyze the status. In addition, depending on the degree of deterioration, some or all of the ester oil can be exchanged to prevent the transformer from malfunctioning when the machine is stopped, such as during regular inspections.
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。 In addition, when deterioration is diagnosed, a means for notifying the deterioration of the ester oil is provided, so that management can be facilitated. For example, it may be provided with an alarm device that determines that the ester oil is degraded when the amount of the aldehyde compound exceeds a predetermined value set in advance, and the like.
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 confirming the deterioration of the ester oil of the appliance is once a week, once a month, and so on. Therefore, it is possible to provide a control device that starts the above-mentioned determination of deterioration in a predetermined period. The control device operates the pump at a predetermined cycle to take the ester oil in the tank to the gas component extraction container, 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, and the ester oil is extracted from the extraction pipe connected to the tank. After the valve is closed, the heater is operated to heat the gas component extraction container to extract a fixed amount of ester oil to extract the aldehyde compound. After the amount of the aldehyde compound is analyzed, the heater is stopped to purify components remaining in the analysis device and the like. Ester oil is less decomposed, so it can be returned to the tank without being discharged outside the system. In addition, the measured amount of the ester oil is small (for example, 50 ml), so 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 appliances such as a plurality of transformers through a gas analysis device and a determination device. The frequency of confirmation of deterioration as described above is once a week, once a month, etc. Therefore, it is possible to create an electrical system having a plurality of electrical appliances and piping switching devices for one analysis device. Individual ester oils can be extracted from a plurality of appliances, and the state of deterioration of the ester oil of each appliance can be grasped.
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 one-time determination may be, for example, about 1 to 5 ml. When the ester oil is large, the amount of gas obtained is easy to quantify, and when the ester oil is small, 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 that lowers the ignition point, so it can be returned to the tank and reused. In this case, it is preferable to provide a pump for returning the ester oil to the tank and returning the ester oil to the pipe. The pump can be controlled by the control device mentioned above. It is also possible to adopt a configuration in which the judged deteriorated ester oil is discarded and supplemented as required.
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。 When an ester oil-doped transformer having the above-mentioned configuration is used, the aldehyde produced in the ester oil 6 is generated by thermal degradation of the ester oil 6 as an insulating and cooling medium contained in the tank 1 during the operation of the transformer, and is dissolved in the ester oil 6 The compounds are analyzed by gas by heating and evaporating the ester oil 6 into the gas phase portion on the liquid surface of the ester oil 6, so that the aldehyde compound generated by the thermal degradation of the ester oil 6 has good efficiency. Simple and easy online quantification, so it can be achieved to make prevention and maintenance of transformers mixed with ester oil easier.
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。 In addition, additives such as a charging preventive agent used in a mineral oil-doped transformer may be added to the ester oil 6 of Example 1.
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 this embodiment, a method for measuring an aldehyde compound in an ester oil-added electrical appliance, an ester oil-added electrical transformer, and an ester oil-containing electrical appliance can be realized. Low-molecular-weight, low-boiling-point aldehyde compounds generated by thermal degradation of ester oils used in cooling media. It is efficient and easy to quantify on-line, and it is possible to prevent changes in electrical appliances that use ester oils as insulation and cooling media. easily.
[實施例2] [Example 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 structure of an ester-doped transformer according to another embodiment will be described with reference to FIG. 4. The transformer of the ester oil-doped transformer shown in FIG. 4 has a configuration in which the gas component extraction container 17 is arranged via a pipe 16 a that communicates with a cooling pipe 9 b provided at a lower portion of the cooler 8. The piping 16a from which this ester oil 6 is extracted is provided so as to communicate with the cooling piping 9b without direct communication with the tank 1. Therefore, the piping 16a can be more easily arranged.
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 ester oil-doped transformer shown in FIG. 4 is basically the same as the ester oil-doped transformer of the first embodiment shown in FIG. 1, and therefore description of the common configuration is omitted. In addition, in the operation of the transformer with an ester oil doped in FIG. 4, the low-molecular-weight and low-boiling-point aldehyde compounds generated by the thermal degradation of the ester oil 6 as an insulation and cooling medium are analyzed and quantified online. Since it is the same as the first embodiment shown in FIG. 1, the description here 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-mentioned embodiment, the determination of aldehyde compounds in an ester oil-added electrical appliance, an ester oil-added electrical transformer, and an ester oil used in an ester oil-containing electrical appliance can be realized as in the previous embodiment described in FIG. 1. The method can be used for the insulation and cooling medium of electrical appliances containing ester oils. The low-molecular-weight and low-boiling aldehyde compounds generated by thermal degradation of ester oils due to thermal degradation can be used to quantify the ester oils efficiently and simply online. Prevention of electrical appliances using insulation and cooling media becomes easy.
[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。 Fig. 5 shows another example of an appliance containing an ester oil. This example is an example in which the ester oil is circulated in the analysis device. In Example 3, the ester oil extraction port was inserted through the pipe 16b from the main body of the tank 1, and the discharge port was a cooling pipe 9b at the lower part of the cooler. The pump system for circulation is omitted. The valves 21a and 21b are opened to circulate the ester oil in the piping of the analysis device. The valve is closed when the internal ester oil is fully replaced with the one at the time of measurement, and the predetermined amount of ester oil in the gas component extraction container 17 is heated. The amount of the aldehyde compound was measured. After the measurement, only the aldehyde compound decreases, so 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。 In addition, although the ester oil may be extracted through the lower cooling pipe 9b, in order to reduce the heating during analysis, it is more efficient to extract from the lower cooling pipe 9a or the upper part of the tank body. In addition, since the flow rate of the cooling piping-based ester oil is high, it is preferable that the discharge port is a piping so that circulation 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。 In addition, in the third embodiment, a function of notifying a diagnosis result is added. The measurement result of the gas analysis device is provided with a power line 24, a signal line 22 through a junction box 23, and an alarm signal line 25 and a constant monitoring signal line 26 to be transmitted to an alarm device, a monitoring device, a memory unit, and the like. The manager can check the deterioration of the ester oil and manage the equipment. For example, it may be provided with an alarm device that judges that the ester oil is degraded and emits an alarm when the amount of the aldehyde compound released exceeds a predetermined value set in advance. The set value is set by investigating the characteristics of the ester oil such as the measured value obtained from the deteriorated ester oil, the volume resistivity, and the like.
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, although a publicly known valve, an alarm device, etc. may be used as appropriate, it is preferable that the valve is opened and the alarm is turned on when the power is stopped.
[實施例4] [Example 4]
接著，說明有關具備氣體分析裝置的摻酯油之電器的運轉模式的一例。利用氣體分析裝置的診斷，係能以每週一次、每月一次等的經設定的頻率進行，或可常時反覆進行。以下，說明按週期進行的使用控制裝置下的診斷之例。氣體分析裝置的運轉，係主要分為測定準備、測定、清掃、定常狀態的4階段。 Next, an example of an operation mode of an ester oil-doped electric appliance including a gas analysis device will be described. The diagnosis by the gas analysis device can be performed at a set frequency such as once a week, once a month, or it can be repeatedly performed at any time. An example of the diagnosis under the use of the control device on a cycle basis will be described below. The operation of the gas analysis device is mainly divided into four stages: measurement preparation, measurement, cleaning, and steady state.
另外，上述的表1的各階段所需的時間，係可依配管的構成、酯油的檢查的頻率、酯油的使用期間等而酌情調整。此外，按一定期間經過進行測定的情況下，係可透過以配管連接複數台電器與一台分析裝置，從而切換配管的流路而進行各電器的監視。 In addition, the time required for each stage of Table 1 described above can be adjusted as appropriate depending on the configuration of the piping, the frequency of inspection of the ester oil, the period of use of the ester oil, and the like. In addition, when the measurement is performed within a certain period of time, the piping can be connected to a plurality of electrical appliances and an analysis device to switch the flow path of the piping to monitor each electrical appliance.
在測定準備階段，係將泵浦、閥開放，將與 槽所連接的提取配管、提取酯油的氣體成分提取容器等中的酯油予以循環。在測定階段，係關閉泵浦、閥，使加熱器作動，而將被氣體成分提取容器提取固定量的酯油進行加熱，提取醛化合物。在清掃階段，係停止加熱器，將殘留於分析裝置等的成分、酯油等淨化、除去。診斷後的酯油係被除去醛化合物等，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(1~50ml程度)，故可廢棄。 In the measurement preparation stage, the pump and valve are opened, and the ester oil in the extraction piping connected to the tank and the gas component extraction container for extracting the ester oil is circulated. At the measurement stage, the pump and valve are closed, the heater is operated, and a fixed amount of ester oil is extracted by the gas component extraction container and heated to extract the aldehyde compound. In the cleaning stage, the heater is stopped to purify and remove components remaining in the analysis device, ester oil, and the like. After diagnosis, the ester oil is removed from the aldehyde compound, etc., and has less decomposition products, so it can be returned to the tank without being discharged outside the system. In addition, the measured amount of the ester oil is small (about 1 to 50 ml), so 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, controls such as means for the manager to be aware of the deterioration of the ester oil, and means for stopping the operation of the appliance containing the ester oil are performed to prevent the abnormality of the machine efficiently and prevent Security becomes 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。 The present invention is not limited to the embodiments described above, and includes various modifications.
