Description

Technical Field

[0001] The present application relates to the technical field of transformer detection, and in particular to a system and method for transformer pressure deformation testing. Background Art

[0002] In the field of power transformer detection technology, testing and analyzing the pressure performance of transformers is an important part of ensuring the stability and reliability of power equipment in a vacuum environment. The standard GB / T6451-2015 "Technical Parameters and Requirements for Oil-Immersed Power Transformers" clearly stipulates that liquid-immersed power transformers need to undergo oil tank pressure deformation tests. Specifically, corrugated oil tanks with a capacity of 315kVA and below must withstand 25kPa air pressure, and corrugated oil tanks with a capacity of 400kVA and above must withstand 20kPa air pressure. There should be no damage and no unacceptable permanent deformation for 5 minutes. During the test, it is necessary to accurately measure and record the maximum deformation of the box cover and box wall during the 5-minute pressure test, as well as the permanent deformation after the air pressure is removed.

[0003] At present, transformer pressure deformation tests are often performed manually using the vernier caliper measurement method. This method requires measurement personnel to set fixed measurement points around and above the transformer casing, manually fix the vernier caliper on the mounting bracket, and measure the distance change before and after the test to obtain the deformation.

[0004] However, the above-mentioned vernier caliper measurement method has the following defects:

[0005] 1. Since the deformation of the box cover and box wall of the transformer during the test is dynamic, and the vernier caliper measurement method is essentially a static measurement method, it is difficult to accurately capture the real-time data during the deformation process. At the same time, the vernier caliper measurement method relies on manual operation and naked eye observation, and it is difficult to accurately measure the dynamic deformation of the transformer shell;

[0006] 2. The traditional transformer pressure deformation test requires that fixed brackets be set around and on the top of the transformer and used as reference points. This process usually takes several hours of preparation, and when any fixed bracket moves, all reference points will change, making the pre-preparation very cumbersome.

[0007] 3. During the transformer pressure deformation test, operators need to face complex environments such as high pressure and vacuum. Since the vernier caliper measurement method involves more manual operations and close contact with the transformer casing, and the inside of the transformer usually needs to form a high pressure value of 50MPa or even 60MPa or be vacuumed during the test, under high pressure or vacuum, if the transformer casing is broken or air vents are formed, the safety risk of the operator will be greatly increased. Any improper operation or equipment failure during the test may lead to safety accidents, posing a potential threat to personnel and equipment. Summary of the invention

[0055] The following is combined with Figure 1-5 This application is described in further detail.

[0056] In one embodiment, the present application discloses a system for transformer pressure deformation test, which specifically includes a data acquisition module, a data processing module, a data transmission module and a control module;

[0057] like Figure 1 As shown, the data acquisition module includes an infrared rangefinder 1, a bracket 2 and a fixed base. In this embodiment, the fixed base is a vacuum suction cup 3. The vacuum suction cup 3 is a device that uses vacuum technology to generate adsorption force. It can fit itself tightly to the ground or wall around the target transformer to provide a stable foundation for subsequent distance measurement work. When the ground or wall is relatively smooth and flat, the vacuum suction cup 3 is selected as the fixed base, so that the data acquisition module is tightly adsorbed on the ground or wall. Optionally, the fixed base can also select a flat plate support structure based on actual conditions. For example, when the ground is uneven, a flat plate support structure can be selected as the fixed base; the infrared rangefinder 1 has a high-precision measurement capability and is used to capture the dynamic deformation data of the transformer casing under the pressure test in real time. The bracket 2 is arranged at the bottom of the infrared rangefinder 1, and the bracket 2 is arranged It is placed on the top of the fixed base to connect the infrared rangefinder 1 and the fixed base. The fixed base is set on the ground or the wall to provide a stable measurement reference for the infrared rangefinder 1. The infrared rangefinder 1 is connected to the data transmission module and the data processing module. The data transmission module is connected to the data processing module. The data processing module is connected to the control module. The data transmission module transmits the data collected by the infrared rangefinder 1 to the data processing module. The data processing module uses the built-in algorithm to process and analyze the received data, so as to obtain accurate deformation data and time-distance relationship curve and other key information. The control module is used to coordinate the collaborative work between the modules to ensure that the test is automatically carried out according to the preset process. Through the precise control of the control module, full automation from data collection, transmission, processing to result output is realized, which significantly improves the efficiency and accuracy of the test.

[0058] The data acquisition module can also be set above the top of the target transformer, such as Figure 2As shown, when it is arranged above the top of the target transformer, the fixed base is a suspension device 4 fixedly connected to one end of the bracket 2 away from the infrared rangefinder 1, and at this time, the data acquisition module is arranged in a suspended manner as a whole;

[0059] Among them, the bracket 2 is set to have an adjustable angle and height, so that the infrared rangefinder 1 can be accurately aligned with the measuring part of the transformer after adjustment, so as to obtain more accurate test data. At the same time, the bracket 2 with adjustable angle and height is also convenient for cooperating with transformer tests of different models. Since transformers of different models may differ in size and structure, by adjusting the height and angle of the bracket 2, it can be ensured that the infrared rangefinder 1 can accurately measure the measuring part of the transformer.

[0060] In this embodiment, specifically, the data processing module includes an initialization unit, a data analysis unit, a result output unit and a timer unit; the initialization unit is connected to the infrared rangefinder 1 in communication, and is used to perform initialization settings on the infrared rangefinder 1. The initialization unit is electrically connected to the control module, and the initialization settings include setting sampling parameters, such as sampling time and sampling frequency, etc., to ensure that the infrared rangefinder 1 can perform accurate measurements according to preset requirements; the data analysis unit is connected to the data transmission module in communication, so as to receive the ranging data from the infrared rangefinder 1 through the data transmission module in real time, and process and analyze the ranging data; the result output unit is connected to the data analysis unit and the control module in communication, so as to receive the processing and analysis results from the data analysis unit and output the processed data to the control module, and the timer unit is electrically connected to the infrared rangefinder 1 and the control module, and is used to perform real-time regulation and control on the working process of the infrared rangefinder 1 based on the control signal sent by the control module;

[0061] Furthermore, in the data processing process, a time series analysis algorithm is introduced to process the shell deformation data collected by the infrared rangefinder 1. The time series analysis algorithm can capture the changing trend of the data over time, so as to more accurately evaluate the deformation of the shell. The introduction of the time series analysis algorithm includes:

[0062] Data preprocessing: clean the raw data to remove noise and outliers;

[0063] Time series modeling: Use time series models such as autoregressive moving average model (ARMA), autoregressive integrated moving average model (ARIMA) or exponential smoothing method (ESM) to model the data;

[0064] Trend analysis: Use the model to predict deformation data at future time points and analyze whether the deformation trend is abnormal;

[0065] Result output: The analysis results are displayed in the form of graphs to facilitate intuitive understanding of the shell deformation;

[0066] Among them, the shell deformation of the target transformer includes elastic deformation and permanent deformation. The calculation function of permanent deformation is: ΔD p =D f -D0, the function of elastic deformation is: ΔD e =D max -D f , where ΔD p is the permanent deformation, that is, the deformation of the target transformer housing that cannot be completely restored to its original shape after pressure is applied, ΔD e D is the elastic deformation, i.e., the deformation of the target transformer housing that can be restored to its original shape after being deformed under pressure. f is the deformation of the target transformer housing after a preset time after the test ends, D0 is the initial state deformation of the target transformer housing before the test begins, and D max is the maximum deformation of the target transformer housing during the test;

[0067] In this embodiment, specifically, the control module includes a control unit and a display unit. The control unit is communicatively connected with the data processing module to start and configure the data processing module and receive processed data from the data processing module. The display unit is communicatively connected with the control unit to display the processed data in real time through a preset display image, such as a chart, a curve or a number, etc.; wherein the startup configuration covers setting the working mode and working parameters of the data processing module, including selecting a specific data processing algorithm, setting the data sampling frequency and accuracy requirements, etc., so as to ensure that the data processing module can complete the data processing task efficiently and accurately according to the predetermined goals and requirements.

[0068] In one embodiment, the present application discloses a method for transformer pressure deformation test, such as Figure 3 As shown, the following steps are included:

[0069] S10: Setting a plurality of groups of data acquisition modules at corresponding positions around the target transformer based on a preset data acquisition strategy;

[0072] S40: When the test termination condition is met, a control signal is sent to the data transmission module through the control module, so that the data transmission module stops receiving the ranging data from the infrared rangefinder;

[0073] In this embodiment, the preset data acquisition strategy is a pre-set data acquisition scheme, which defines key parameters such as the timing, frequency, and location of data acquisition, as well as the number and arrangement of infrared rangefinders, so as to ensure that the deformation data of the target transformer housing in the pressure test can be fully and accurately obtained. Figure 4 As shown, in this embodiment, several data acquisition modules are arranged in two groups as one part, and each part array is arranged around the target transformer shell and above the top, wherein each part equidistant array can be selected to be arranged around the target transformer shell and above the top to improve the detection accuracy; the control module is the control center of the whole system, which is responsible for sending control signals to each module to coordinate the operation of the whole system; the data transmission module is used to receive the distance measurement data from the infrared rangefinder in real time, and transmit these data to the data processing module quickly and accurately, which is the Bluetooth gateway in this embodiment; the infrared rangefinder is an instrument that uses infrared technology to measure distance, which can The distance between the target transformer housing and the distance meter is measured contactlessly, thereby indirectly reflecting the deformation of the housing; the data processing module is used to receive the distance measurement data from the data transmission module, and use pre-configured algorithms and technologies to process and analyze these data to extract key information about the deformation of the transformer housing; the processed data is the data processed and analyzed by the data processing module, which contains key information about the deformation of the target transformer housing, such as deformation amount, deformation rate, etc.; the test termination condition is a set of preset conditions. When the test termination conditions are met, the test will be automatically terminated. The test termination conditions include the test time reaching the preset value, the deformation amount exceeding the allowable range, etc.;

[0074] Specifically, a method for transformer pressure deformation test corresponds to its system. According to a preset data acquisition strategy, several groups of data acquisition modules are set on the shell end face of the target transformer to ensure that the deformation of the transformer shell in the pressure test can be flexibly and accurately captured. At the same time, a fixed base is set on the ground or wall to provide a stable basis for subsequent distance measurement work; the control module sends a control signal to the data transmission module, instructing the data transmission module to start receiving the distance measurement data from the infrared rangefinder in real time, and to perform in-depth processing and analysis on it. During this process, the data processing module analyzes the distance measurement data and extracts key information about the deformation of the transformer shell; the control module is not only responsible for starting the data transmission and data processing process, but also receives the output results from the data processing module in real time, providing operators with intuitive and accurate test progress and result information, so that they can quickly make judgments and decisions; when the test reaches the preset termination condition, the control module sends a control signal to the data transmission module to stop receiving the distance measurement data, marking the end of the entire test process.
