[0002] The safe operation and maintenance of power systems require the combined efforts of multiple devices. Power transformers are expensive but have significant impacts and are widely involved. Therefore, research to ensure their safe operation is of great significance. Transformer windings are critical components of transformers, subject to high voltage, high current, high field strength, strong mechanical loads, and high thermal loads during operation. Therefore, copper, which outperforms aluminum in physical properties (resistivity), mechanical properties (Brinell hardness, tensile strength), and thermodynamic properties (thermal conductivity), is the preferred material for transformer windings. However, since the market price of aluminum is significantly lower than that of copper, and the national standard stipulates that copper materials used in transformer windings should not be labeled with letter codes, some manufacturers use aluminum instead of copper in transformer production, seriously affecting the performance of the equipment and the order of the industry. In this regard, the existing transformer winding material detection device to be tested, which is made based on the difference in thermoelectric effect between aluminum and copper materials, realizes non-destructive testing of the winding material of dry-type distribution transformers. However, in the existing process of producing transformer winding material detection devices, the effectiveness of the use of the produced transformer winding material detection devices is still tested step by step by manual testing of the effectiveness of the hardware and software measurements of the transformer winding material detection devices, which has high labor costs; especially for multiple transformer winding material detection devices to be tested continuously, the incoming wire end of the standard winding used for testing needs to be repeatedly heated and dissipated, and the efficiency of using manual experience for detection is low.

[0018] In response to the problems of high labor cost, low automation level and inefficiency in the current effectiveness testing of transformer winding material testing devices, especially multiple transformer winding material testing devices to be tested continuously, the present invention provides a transformer winding material testing device effectiveness testing system.

[0019] See Figure 1In one embodiment, the above-mentioned transformer winding material detection device effectiveness test system includes: a carrying module, a sample module, a temperature acquisition module, a thermoelectric potential acquisition module, a signal acquisition module, a visual module, a heating module, a heat dissipation module, an analysis module, a control module, a motion module and a plurality of wires; wherein the sample module is used to provide a standard winding, and the standard winding includes a pure copper winding and a copper-aluminum winding; the carrying module is used to place the transformer winding material detection device to be tested; the heating module is used to heat the incoming terminal of the sample module; the heat dissipation module is used to dissipate heat from the heated incoming terminal of the sample module; the temperature acquisition module is used to measure the temperature of the incoming terminal and the outgoing terminal of the sample module in real time; the thermoelectric potential acquisition module is used to collect first potential change data at both ends of the sample module when heated, and the first potential change data includes the potential of the incoming terminal and the outgoing terminal collected by the thermoelectric potential; the visual module is used to obtain a visual image of the transformer winding material detection device to be tested on the carrying module; and the control module is used to locate the transformer winding material detection device to be tested according to the visual image. The cold-end potential measurement connector and the hot-end potential measurement connector are positioned, and a motion instruction for controlling the motion module is generated based on the positioning result. The motion module is also used to control the operating states of the temperature acquisition module, the thermoelectric potential acquisition module, the heating module, the heat dissipation module, and the transformer winding material detection device to be tested based on the visual image. The motion module is used to clamp the wire connecting the hot-end potential measurement connector and the incoming wire end of the sample module, and to clamp the wire connecting the cold-end potential measurement connector and the outgoing wire end of the sample module according to the control instruction. The signal acquisition module is used to collect second potential change data and winding material detection results of both ends of the standard winding detected by the transformer winding material detection device to be tested during operation, the second potential change data including the potentials of the incoming wire end and the outgoing wire end measured by the transformer winding material detection device to be tested. The analysis module is used to determine the effectiveness of the transformer winding material detection device to be tested using the winding material detection results in combination with the condition of the standard winding provided by the sample module, and to obtain a measurement error of the transformer winding material detection device to be tested using the first potential change data and the second potential change data.

[0020] In this example, see Figure 1The sample module is connected to the temperature acquisition module and the thermoelectric potential acquisition module; the control module is respectively connected to the temperature acquisition module, the thermoelectric potential acquisition module, the signal acquisition module, the vision module, the heating module, the heat dissipation module, the analysis module, and the motion module signals. The present invention realizes the intelligent automatic control of the effectiveness detection of the use of the transformer winding material detection device through the interaction of the vision module, the motion module and the control module, and controls the working status of the temperature acquisition module, the thermoelectric potential acquisition module, the heating module and the heat dissipation module through the control module; at the same time, through the core control capability of the control module, it can well meet the control requirements of continuous heating and heat dissipation switching of multiple transformer winding material detection devices to be continuously detected and the control of the operating time of each module, thereby ensuring the accuracy of the detection results and improving the detection efficiency.

[0021] It should be understood that the sample module described in the present invention provides a standard winding not only for use in measurements by the transformer winding material detection device under test, but also as a reference data source for evaluating the effectiveness and accuracy of the measurements made by the transformer winding material detection device under test. Therefore, the standard winding provided by the sample module clearly defines the data corresponding to the first thermoelectric effect. Specifically, when one end of the standard winding is heated while the other end remains at room temperature, the corresponding potential change curve at both ends is clear, and the Seebeck coefficient of the standard winding is also known. The pure copper winding has a copper content of 99.99%, making it approximately pure copper metal. The copper-aluminum winding is designed based on the copper-aluminum combination winding types encountered in actual engineering.

[0022] The aforementioned mounting module is a platform for placing the transformer winding material detection device to be tested. By placing the transformer winding material detection device to be tested on the mounting module, the visual module can effectively capture the operating screen of the transformer winding material detection device to be tested. In an optional embodiment, the operating screen of the transformer winding material detection device to be tested includes: a flashing operating indicator light of the transformer winding material detection device to be tested, a display interface of the touch screen display, and switching operating screens of the touch screen display. In this embodiment, the mounting module is a rectangular platform, and both short sides of the platform are connected to rolling tracks, suitable for continuous measurement of the transformer winding material detection device to be tested.

[0023] In actual engineering, when testing transformer winding materials using the first thermoelectric effect, temperatures exceeding 120 degrees Celsius can affect the transformer's performance. Therefore, the maximum temperature limit provided by the heating module of the present invention is set to 120°C. The upper temperature limit of the heating module is limited through actual engineering, which limits the power consumption standard of the heating device, saving energy to a certain extent and facilitating the acquisition of the heating device. Furthermore, the heat dissipation module of the present invention not only dissipates heat from the heated sample module's incoming terminal but also maintains the initial temperature of the sample module's outgoing terminal, which can be room temperature or another lower temperature. During the heating process of the sample module's incoming terminal, due to the relative position of the heating device and the outgoing terminal, the temperature of the outgoing terminal may be affected by the heating device, or by environmental factors. Therefore, the heat dissipation module is used to maintain the temperature of the outgoing terminal. In an optional embodiment, the heating module is a thermistor, which is easy to obtain and simple to control. In an optional embodiment, the heat dissipation module is a liquid cooling circulation device, which has high heat dissipation efficiency and can meet the demand for rapid temperature reduction.

[0024] To further shorten detection time and ensure detection accuracy, the temperature acquisition module provided by the present invention must meet the requirements of fast response speed and high data accuracy. In an optional embodiment, the temperature acquisition module provided by the present invention can choose to use a temperature sensor based on the thermocouple principle. This type of temperature sensor has a high measurement response speed and high data accuracy, meets actual detection requirements, and is easy to control.

[0025] The visual module can track the positions of the cold-end potential measurement connector and the hot-end potential measurement connector in a dynamic visual image of the transformer winding material detection device under test as it moves, and can also locate the positions of the cold-end potential measurement connector and the hot-end potential measurement connector in a static image of the transformer winding material detection device under test fixed to the mounting module. The image intelligent recognition technology involved is existing technology. In an optional embodiment, the visual module not only provides technical module support for the intelligent automation of hardware detection of the transformer winding material detection device under test, but also provides the possibility of detecting the smoothness of software operation in the transformer winding material detection device under test. In this embodiment, the analysis module is also used to determine the smoothness of software operation in the transformer winding material detection device under test using the visual image captured by the visual module. That is, the visual module can detect the normal display of the display interface of the touch screen display of the transformer winding material detection device under test and the switching of the touch screen working interface, and execute software operation for evaluation.

[0026] In an optional embodiment, the control module can control the operating states of the motion module, temperature acquisition module, thermoelectric potential acquisition module, heating module, heat dissipation module, and the transformer winding material detection device using a PLC programming language combined with a PID controller. Furthermore, in this embodiment, the motion module is a robotic arm whose trajectory can be modified using the PLC language.

[0027] It should be understood that the electric potentials of the incoming and outgoing terminals of the sample module collected by the thermoelectric potential acquisition module provided by the present invention are reference data for calibrating the electric potentials of the incoming and outgoing terminals collected by the transformer winding material detection device to be tested; the second electric potential change data collected by the signal acquisition module provided by the present invention are actual data for evaluating the effectiveness of the detection of the transformer winding material detection device to be tested. The collected second electric potential change data and the winding material detection results are all recorded and stored on the transformer winding material detection device to be tested. Therefore, the corresponding data can be exported by using the data transmission line matching analysis module and the data output port of the transformer winding material detection device to be tested. In an optional embodiment, the data output port of the transformer winding material detection device to be tested is a Type-A USB data interface. In this embodiment, the signal acquisition module is a Type-A USB data cable.

[0028] In order to ensure the rapid detection of the effectiveness of the use of multiple transformer winding material detection devices to be tested continuously, based on the transformer winding material detection device effectiveness testing system provided by the present invention, the present invention also provides a transformer winding material detection device effectiveness testing method, see Figure 2 The effectiveness testing method of the transformer winding material detection device includes the following steps:

[0029] S01. The control module controls the motion module to assist the transformer winding material detection device to be tested to be placed in a designated position according to the visual image captured by the visual module.

[0030] S02. The control module controls the visual module to obtain a visual image of the transformer winding material detection device to be tested on the carrying module.

[0031] S03. The control module positions the cold end potential measurement connector and the hot end potential measurement connector of the transformer winding material detection device to be tested at the designated positions according to the control vision module.

[0032] S04. The control module locates the cold-end potential measurement connector and the hot-end potential measurement connector of the transformer winding material detection device to be tested according to the visual image, and controls the motion module to clamp the wire to connect the hot-end potential measurement connector and the incoming terminal, and at the same time controls the motion module to clamp the wire to connect the cold-end potential measurement connector and the outgoing terminal of the sample module.

[0033] S05. The control module controls the motion module to start the transformer winding material detection device to be tested according to the visual image.

[0034] S06. The control module controls the temperature acquisition module to measure the temperatures of both ends of the incoming and outgoing terminals of the sample module in real time, controls the operating states of the heating device and the heat dissipation device according to the temperature value of the temperature acquisition module, and controls the thermoelectric potential acquisition module to collect the first electric potential change data when the sample module is heated.

[0035] S07. The control module uses the signal acquisition module to acquire the second potential change data at both ends of the standard winding and the winding material detection result obtained when the transformer winding material detection device to be tested is working.

[0036] S08. The analysis module uses the winding material detection results in combination with the standard winding conditions provided by the sample module to determine the effectiveness of the transformer winding material detection device to be tested, and uses the first potential change data and the second potential change data to obtain the measurement error of the transformer winding material detection device to be tested.

[0037] The transformer winding material detection device effectiveness testing method provided by the present invention is proposed based on the transformer winding material detection device effectiveness testing system, and has a high degree of adaptability to the transformer winding material detection device effectiveness testing system, ensuring the stability of the corresponding device operation and improving the detection efficiency.

[0038] In an optional embodiment, in S06 of the method for testing the effectiveness of a transformer winding material detection device provided by the present invention, the control module controls the operating states of the heating device and the heat dissipation device based on the temperature value of the temperature acquisition module, including the following steps: the control module controls the heating device to heat the incoming terminal until the temperature value of the incoming terminal collected by the temperature acquisition module reaches a set value, and then controls the heat dissipation device to cool the incoming terminal until the temperature value of the incoming terminal collected by the temperature acquisition module returns to the initial temperature of the incoming terminal; the control module controls the heat dissipation device to maintain the temperature value of the outgoing terminal collected by the temperature acquisition module within the variable range of the initial temperature of the outgoing terminal. The control module serves as the core of the entire set of transformer winding material detection device effectiveness testing. When multiple consecutive transformer winding material detection devices are to be tested, the control module improves the detection efficiency by controlling the timely switching of the operation of the heating device and the heat dissipation device.

[0039] In yet another alternative embodiment, see Figure 3The analysis module described in S08 of the effectiveness testing method for a transformer winding material detection device provided by the present invention uses the winding material detection results combined with the standard winding conditions provided by the sample module to determine the effectiveness of the transformer winding material detection device to be tested, and uses the first potential change data and the second potential change data to obtain the measurement error of the transformer winding material detection device to be tested. The method includes the following steps: when the winding material detection results do not meet the standard winding conditions, the transformer winding material detection device to be tested is determined to be unqualified. When the winding material detection results meet the standard winding conditions, the measurement error of the transformer winding material detection device to be tested is obtained based on the first potential change data and the second potential change data. The actual effectiveness of the detection device is evaluated using the measurement error, and an effectiveness threshold is set; when the actual effectiveness meets the effectiveness threshold, the transformer winding material detection device to be tested is determined to be qualified; when the actual effectiveness does not meet the effectiveness threshold, the measurement error is used to generate potential difference calibration data and transmit it to the control module. In this embodiment, when the standard winding is a copper-aluminum winding, the winding material test result is a pure copper winding. At this time, the winding material test result does not meet the standard winding condition, and the corresponding transformer winding material detection device to be tested is also unqualified. Other winding material test results can be obtained in the same way. In this embodiment, the measurement error of the transformer winding material detection device to be tested is obtained based on the first potential change data and the second potential change data. The comparison value of the output terminal potential and the input terminal potential in the first potential change data and the second potential change data at the same temperature is obtained. Taking the first potential change data as the standard, if the data corresponding to the second potential change data is larger, then its measurement error is a negative error. The potential difference calibration data subsequently generated using this measurement error is also negative potential difference calibration data, that is, the initial potential value of the corresponding terminal of the transformer winding material detection device to be tested is calibrated to the negative potential difference; otherwise, it is positive. At the same time, the actual effectiveness of the detection device evaluated by the measurement error is to determine the accuracy and stability of the measurement results of the detection device by the size of the measurement error. In this embodiment, the effectiveness threshold can be determined by those skilled in the art based on parameters related to the actual yield determination process.

[0040] In another optional embodiment, the effectiveness testing method of the transformer winding material detection device provided by the present invention further includes the following steps: the analysis module determines the running fluency of the software in the transformer winding material detection device to be tested based on the visual image. By analyzing the visual image captured by the visual module through the analysis module, the software running in the transformer winding material detection device to be tested is detected and evaluated, thereby improving the working performance of the corresponding device. At the same time, in this embodiment, the effectiveness testing method of the transformer winding material detection device provided by the present invention further includes the following steps: the control module controls the motion module to correct the preset parameters of the transformer winding material detection device to be tested based on the measurement error. Among them, the preset parameters are the initial potential values ​​of the corresponding ends of the transformer winding material detection device to be tested. In the actual process flow, by correcting the transformer winding material detection device to be tested with large measurement errors, the overall production yield can be improved and the process conversion value can be maximized.
