Description

Technical Field

[0002] Power transformer failure may cause power supply interruption, equipment damage or even explosion, posing a serious threat to the safe and stable operation of the power grid. Therefore, timely and accurate diagnosis of whether there is a fault inside the power transformer is an important part of power system maintenance and management. At present, the internal fault diagnosis method based on dissolved gas analysis (DGA) is internationally recognized as one of the most effective methods, among which the online chromatographic monitoring device can detect whether there is a fault in the equipment more timely. According to relevant statistics, due to equipment aging, baseline drift and other reasons, the measurement accuracy of the transformer oil online chromatographic monitoring device in operation is low.

[0003] In order to ensure the accuracy and stability of the monitoring results of the transformer oil chromatography monitoring device, it is necessary to use the calibration oil sample to regularly calibrate the transformer oil chromatography monitoring device. The existing calibration oil sample preparation method is: add the preset gas to the new transformer oil, and according to the calculation, add different volumes of gas to the three oil samples to prepare three concentration oil samples of high concentration, medium concentration and low concentration. The existing configuration method has low configuration efficiency, and the configuration oil sample has a concentration gradient of some components that cannot meet the ideal requirements due to the mutual influence between the gases (for example, the H in the configured high concentration oil is 2 May be lower than H in low concentration oil 2 ) and other issues, which seriously affect the efficiency of on-site calibration. How to configure a method with obvious and stable oil sample gradient, simple and efficient is a technical problem that needs to be solved urgently by technicians in this field.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The existing method for preparing the calibration oil sample is to add a preset gas, such as CH 4 , C 2 H 4 , C2 H 6 , C 2 H 2 , H 2 ,CO,CO 2 Add to the new transformer oil. According to the calculation, three oil samples were added with different volumes of CH 4 , C 2 H 4 , C 2 H 6 , C 2 H 2 , H 2 ,CO,CO 2 Gas was used to prepare three concentrations of oil samples: high concentration, medium concentration and low concentration. The existing preparation method has low preparation efficiency, and the concentration gradient of some components of the prepared oil samples cannot meet the ideal requirements due to the mutual influence of gases (for example, H 2 May be lower than H in low concentration oil 2 ). At the same time, in the configuration method of the prior art, three oil distribution devices are often required to achieve configuration, which is very inconvenient. To this end, this application proposes a mixed standard oil configuration method to solve the problem. In order to clearly describe a mixed standard oil configuration method provided by this embodiment, please refer to Figure 1 .

[0029] Step S110: When the configuration requirement is obtained, the configuration requirement is parsed to determine the oil sample information of the target oil sample, where the oil sample information includes the gas type and the target gas concentration.

[0030] In one embodiment, the configuration requirement is an instruction for configuring the standard oil. Through analysis, it can be determined what kind of standard oil is desired to be configured in this requirement. That is, what gases are required in the standard oil, and what is the required concentration ratio of each gas. Correspondingly, the oil sample information obtained by analyzing the configuration requirement indicates the specific gas types contained in the target oil sample required by the configuration requirement, and the target gas concentration required for each gas.

[0031] Step S120: configuring at least one first oil sample according to the gas type, each first oil sample contains only one preset gas, and the preset gas in the first oil sample is in a saturated state; and mixing all the first oil samples to obtain a second oil sample.

[0032] In one embodiment, at least one first oil sample is configured according to the gas type, including: obtaining a blank oil sample of a preset volume and adding it into a closed container, performing an initialization operation on the blank oil sample until the blank oil sample is in an initial state; continuously introducing a preset gas into the closed container to obtain first concentration data of the blank oil sample; when the first concentration data exceeds a preset threshold and is maintained for more than a preset time, marking the blank oil sample as the first oil sample.

[0033] In one embodiment, the preset gas includes: CH 4 , C 2 H 4 , C 2 H 6 , C 2 H 2 , H 2 ,CO,CO 2 .

[0034] In one embodiment, the method provided in the present application is used for the configuration of standard oil for online oil chromatography calibration. The core idea of ​​this method is: first configure multiple single-component gas single-standard saturated oil mother liquids, which are called first oil samples. Then, according to the configuration requirements, different volumes of the first oil samples are taken and mixed to obtain the second oil sample, and the concentration ratio is adjusted according to the second oil sample and configured according to the requirements to obtain the target oil sample. Therefore, it is necessary to configure the first oil sample first, and only one preset gas is dissolved in each first oil sample, and the preset gas is dissolved to a saturated state.

[0035] The first oil sample configuration process may be to first obtain N sealed containers, each of which has the same volume, and the number N is determined according to the number of gas types in the oil sample information. Add the blank oil sample mentioned in the same way to each sealed container, and perform the initialization operation on the blank oil sample until the blank oil sample is in the initial state. It can be understood that the solubility of the gas is related to the temperature and air pressure. In order to achieve controllable solubility, it is necessary to set the state of the blank oil sample to a preset initial state. For example, the blank oil sample may be heated to 50-80°C under normal atmospheric pressure. After the blank oil sample is heated or pressurized according to the initial operation control, and the temperature and air pressure of the blank oil sample are kept in this state, it can be said that the blank oil sample is in the initial state.

[0036] This can then be done by continuously passing a preset gas (e.g. CH 4 , C 2 H 4 , C 2 H 6 , C 2 H 2 , H 2 , CO or CO 2) until the blank oil sample dissolves the corresponding preset gas until it is saturated. The saturation judgment standard can be the first concentration data of the blank oil sample obtained by the sensor in the closed container. When the first concentration data exceeds the preset threshold and is maintained for more than the preset time, it can be determined that the oil sample is saturated, and the blank oil sample is marked as the first oil sample. It can be understood that different preset gases have different solubilities in blank oil samples, so the preset threshold needs to correspond to the preset gas, and the judgment process needs to obtain the corresponding preset threshold according to the dissolved preset gas. Through this operation, the first oil sample of N single-component saturated oils can be obtained.

[0037] The difference from the prior art is that the present application configures only one preset gas each time the first oil sample is configured until it is saturated, while the prior art requires configuring multiple gases at a time. Therefore, the method provided by the present application only requires one oil distribution device during the configuration process, while the prior art generally requires three or more oil distribution devices to complete the configuration. The configuration method provided by the present application is simpler and faster, reduces equipment requirements, and makes the solution easier to implement. It can also be used immediately after being configured, avoiding distortion of samples prepared in the laboratory.

[0038] In one embodiment, all first oil samples are mixed to obtain a second oil sample, including: obtaining a standard oil volume and second concentration data of a mixing container, the mixing container is used to mix the first oil samples, and the second concentration data is the concentration of a corresponding preset gas in each first oil sample; determining a target volume of each first oil sample according to the standard oil volume, the second concentration data and the target gas concentration; obtaining a first oil sample of the target volume and adding it to the mixing container, and adding a blank oil sample until the volume of the oil sample in the mixing container reaches the standard oil volume; mixing the oil sample in the mixing container until a mixing condition is met, and marking the oil sample in the mixing container as the second oil sample.

[0039] In one embodiment, multiple first oil samples are configured first, but the target oil sample usually needs to dissolve multiple gases, so multiple first oil samples need to be mixed. And it can be understood that the target oil sample has requirements for the concentration of each preset gas, and the first oil samples cannot be directly mixed. Because if they are directly mixed, the dissolved ratio of each gas in the obtained oil sample is saturated, and the corresponding ratio is fixed and cannot be adjusted.

[0040] For this reason, when mixing the first oil samples, it is necessary to select the volume of each first oil sample to ensure that the dissolved ratio of each preset gas in the mixed oil sample corresponds to the target oil sample. To understand the process, an example is given for explanation. Assume that according to the configuration requirements, 5L of 7-component mixed oils of 3 concentrations are required. The required preset gas of the target oil sample under different concentration conditions and the target gas concentration of each preset gas refer to the following table:

[0041] Components <![CDATA[CH 4 ]]> <![CDATA[C 2 H 4 ]]> <![CDATA[C 2 H 6 ]]> <![CDATA[C 2 H 2 ]]> <![CDATA[H 2 ]]> CO <![CDATA[CO 2 <!-- 4 -->]]> High concentration μL / L 50 50 60 10 200 500 2000 Medium concentration μL / L 10 10 12 2 40 10 400 Low concentration μL / L 2 2 2.4 0.4 8 2 80

[0042] Table 1 Configuration requirements of target oil samples

[0043] According to the configuration method in the previous article, 7 first oil samples with a volume of 1L are configured, which are called oil samples 1 to 7. The concentration data of each first oil sample is obtained, which is called the second concentration data. 1L is the standard oil volume. For the second concentration data, please refer to Table 2:

[0044]

[0045] Table 2 Second concentration data of the first oil sample

[0046] From the table data, it can be seen that if the first oil sample is directly mixed, the ratio of each preset gas is quite different from the target oil sample. Therefore, in order to adjust the ratio, when the volume of the mixing container containing the mixed oil sample is known, the target volume of each first oil sample can be determined according to the standard oil volume, the second concentration data and the target gas concentration. The specific calculation method can be referred to as follows:

[0047]

[0048] Where V i,x is the target volume, which is used to indicate the volume required to be extracted for each first oil sample; V is the standard oil volume; C i,1 is the target gas concentration; C i,0 is the second concentration data.

[0049] Assuming that 5L of mixed oil sample is required, that is, the standard oil volume, and then according to the above target gas concentration and second concentration data are substituted into the above formula (1), the required volume of each first oil sample can be calculated respectively. The specific settlement process can be referred to as follows:

[0050] Vi,CH4=5L*100μL / L / (11700μL / L)=0.0427L (2)

[0051] Vi,C2H4=5L*100μL / L / (43800μL / L)=0.0114L (3)

[0052] Vi,C2H6=5L*120μL / L / (69000μL / L)=0.0087L (4)

[0053] Vi,C2H2=5L*100μL / L / (30600μL / L)=0.0033L (5)

[0054] Vi,H2=5L*400μL / L / (1800μL / L)=1.1111L (6)

[0055] Vi,CO=5L*1000μL / L / (3600μL / L)=1.3889L (7)

[0056] Vi,CO2=5L*4000μL / L / (27600μL / L)=0.7246L (8)

[0057] That is, only part of the volume of each first oil sample is needed. Specifically, 0.0427L of oil sample 1, 0.0114L of oil sample 2, 0.0087L of oil sample 3, 0.0033L of oil sample 4, 1.1111L of oil sample 5, 1.3889L of oil sample 6, and 0.7246L of oil sample 7 are added to a 5L mixing container, and the remainder is added to a blank oil sample to make up to 5L, which is the standard oil volume. The oil samples in the mixing container are stirred and mixed. After the oil is allowed to stand for 24 hours, the resulting oil sample is marked as the second oil sample. Among them, stirring evenly and standing for 24 hours can also be mixing conditions to ensure that each first oil sample and blank oil sample in the oil sample are fully mixed. This condition is only an example of a preferred implementation of this embodiment. In actual situations, the mixing conditions can be adjusted arbitrarily according to actual needs, and this application does not make specific restrictions.

[0058] In the process of configuring the target oil sample according to the method provided in the present application, since the oil sample is mixed in the mixing process, rather than the gas mixture. It is understandable that the mixing process is not the fusion of gas and oil sample. The configuration of single-component saturated oil reduces the interference between the gas components and reduces the mutual influence of each component when it is individually inhaled, and the oil is more stable. At the same time, the use of single-component saturated oil to configure oil samples of other concentrations is simpler than adding gas because oils are more soluble in each other, and the mixing process is faster. And no calculation is required when configuring the single-component saturated oil of the first oil sample, which is easier and more accurate than adding gas after calculation, and the process is simpler. The existing method generally calculates the multiple gases that need to be added based on the high, medium and low concentrations. Assuming that 7 preset gases are required, three concentrations of standard oil are configured, and 7 gases are added to the high, medium and low concentrations according to the calculated results (a total of 3*7=21 times of gas addition). The configuration process is complicated and not easy to operate.

[0059] Step S130: adding a blank oil sample to the second oil sample until the gas concentration in the second oil sample matches the target gas concentration; marking the second oil sample after adding the blank oil sample as the target oil sample.

[0060] In one embodiment, the ratio of each preset gas dissolved in the second oil sample obtained by the above mixing is the same as that in the target oil sample. However, in general, the dissolved concentration of each preset gas in the second oil sample is usually higher than that in the target oil sample, and further adjustment is required. For example, in the example given above, after stirring and mixing, the second oil sample is obtained, and the concentration is as follows: CH 4 :100μL / L,C2 H 4 :100μL / L,C 2 H 6 :120μL / L,C 2 H 2 :100μL / L,H 2 : 400μL / L, CO: 1000μL / L, CO 2 : 4000μL / L. Compared with the concentration of the target oil sample shown in Table 1, the concentration ratio between the gases is the same, but the second oil sample has a higher concentration. Even compared with the high-concentration target oil sample, it is twice as high. Therefore, to obtain a high-concentration target oil sample from the second oil sample, a blank oil sample of the same volume must be added to the second oil sample. The oil sample whose concentration data is the same as the target gas concentration after adding the blank oil sample can be marked as the target oil sample.

[0061] In one embodiment, after marking the second oil sample after adding the blank oil sample as the target oil sample, the method further includes: when the concentration requirement is obtained, determining a concentration step volume set according to the concentration requirement, the concentration step volume set includes N step volumes, each step volume is arranged in a step-like manner, and N is a natural number; respectively obtaining target oil samples of step volumes, and adding them to N standard oil containers with the same volume; respectively adding blank oil samples to the standard oil containers until the volume of the oil samples in the standard oil containers is a preset volume; marking the oil samples in the standard oil containers as step concentration standard oils, the proportions of the preset gases in the step concentration standard oils are the same, but the concentrations are arranged in a step-like manner.

[0062] In one embodiment, as shown in Table 1, under normal circumstances, the target oil sample is often not one portion, but a plurality of oil samples of different concentrations need to be configured in a stepped manner, for example, the three concentrations of high, medium and low in Table 1 are 5 times each other, and the demand for this concentration step arrangement is called the concentration demand. The target oil sample can be further configured according to the concentration demand, so as to configure a stepped concentration standard oil. The stepped concentration standard oil can include multiple portions, and the ratio of each preset gas in each portion of the stepped concentration standard oil is the same, but the concentrations are arranged in a stepped manner. For ease of understanding, the above embodiments are used for explanation.

[0063] Assuming the three concentrations of high, medium and low in Table 1, which are the concentration requirements, the volume of the target oil sample that needs to be obtained at different concentrations can be determined by referring to the calculation method of formula (1) by taking the target gas concentration of the target oil sample and the volume of the standard oil container. This set of values ​​is also the concentration step volume set.

[0064] Specifically, assuming that 5L of high-concentration oil sample is to be prepared, 2.5L of target oil sample and 2.5L of blank oil sample are required through calculation. Referring to the mixing method mentioned above, 5L of high-concentration oil sample can be obtained by mixing them evenly in a standard oil container. The concentration data of high-concentration oil sample is: CH 4 :50μL / L,C 2 H 4 :50μL / L,C 2 H 6 :60μL / L,C 2 H 2 :50μL / L,H 2 :200μL / L, CO: 500μL / L, CO 2 : 2000μL / L.

[0065] Approximately, to prepare 5L of medium-concentration oil sample, you need to obtain 0.5L of target oil sample and 4.5L of blank oil sample through hormone, and mix them evenly to obtain 5L of medium-concentration oil sample. The concentration data of medium-concentration oil sample is: CH 4 :10μL / L,C 2 H 4 :10μL / L,C 2 H 6 :12μL / L,C 2 H 2 :10μL / L,H 2 : 40μL / L, CO: 100μL / L, CO 2 :400μL / L.

[0066] Approximately, to prepare 5L of low-concentration oil sample, you need to obtain 0.1L of target oil sample and 4.9L of blank oil sample through hormone, and mix them evenly to get 5L of low-concentration oil sample. The concentration data of low-concentration oil sample is: CH 4 :2μL / L,C 2 H 4 :2μL / L,C 2 H 6 :2.4μL / L,C 2 H 2 :2μL / L,H 2 :8μL / L,CO:20μL / L,CO 2 : 100μL / L.

[0067] The high-concentration oil sample, medium-concentration oil sample, and low-concentration oil sample obtained after configuration are collectively referred to as step-concentration standard oil. The proportion of each oil sample in the step-concentration standard oil is the numerical value. The concentration of the mixed oil sample configured in this application is relatively high. The advantage is that when you go to the substation to calibrate the equipment on site, you only need to carry a small volume of the first oil sample, and add blank oil on site to configure three different concentrations (high, medium, and low) of calibration oil.

[0068] In one embodiment, the second oil sample after adding the blank oil sample is marked as the target oil sample, including: obtaining third concentration data of the target oil sample, and comparing the third concentration data with the target gas concentration; if the third concentration data has a concentration of a preset gas that does not match the target gas concentration, determining the filling volume based on the third concentration data and the target gas concentration; obtaining the first oil sample with the filling volume and adding it to the target oil sample until the third concentration data matches the target gas concentration.

[0069] In one embodiment, after the target oil sample is configured, the target oil sample can be calibrated. The third concentration data of the target oil sample is obtained, and the third concentration data is compared with the target gas concentration to determine whether the concentration data of the preset gas in the target oil sample matches the target gas concentration. Whether it matches can be to determine whether the values ​​are equal, or whether they fall within a preset threshold range. If there is a mismatch between the concentration of the preset gas and the concentration of the target gas, it means that the concentration of the gas needs to be supplemented, or the concentration of the remaining gases is too low. According to the idea of ​​"adding flour to more water and adding water to more flour", the gas that needs to be supplemented is determined. According to the idea of ​​calculating the target volume of the first oil sample in the previous formula (1), the required filling volume of the first oil sample is calculated. Then mix the first oil sample corresponding to the filling volume into the original target oil sample until the third concentration data matches the target gas concentration, thereby ensuring the accuracy of the value of the target oil sample.

[0070] At the same time, it can be understood that, referring to the process of configuring the second oil sample in the previous text, during the configuration process, when collecting the first oil sample of the target volume, the target volume value has reached four decimal places, and the required accuracy is relatively high. It is inevitable that errors will occur during the configuration process. Although the error can be controlled within an acceptable range through the calibration process in the previous text, the error is also difficult to ignore. Therefore, in a preferred embodiment, after the calibration is completed, the actual concentration data of the target oil sample after calibration is used as the subsequent processing data to ensure the corresponding accuracy.

[0071] Therefore, the present application can only carry or configure a small volume of the first oil sample when calibrating the equipment at the substation site, and add blank oil according to the method provided by the present application to configure the calibration oil required by the configuration requirements. Since each first oil sample contains a component of a preset gas and is in a saturated state, it avoids the interference caused by injecting multiple preset gases at the same time in the existing oil distribution method, reduces the mutual influence of each preset gas when it is individually inhaled, and the resulting oil sample is more stable.

The mixed standard oil configuration device includes: a parsing module 21, a first configuration module 22 and a second configuration module 23. The parsing module 21 is used to parse the configuration requirements to determine the oil sample information of the target oil sample when the configuration requirements are obtained.

The first configuration module 22 is used to configure at least one first oil sample according to the gas type, each first oil sample has only one preset gas, and the preset gas in the first oil sample is in a saturated state; all the first oil samples are mixed to obtain a second oil sample. The second configuration module 23 is used to add a blank oil sample to the second oil sample until the gas concentration in the second oil sample matches the target gas concentration; and mark the second oil sample after the blank oil sample is added as the target oil sample.
