Description

Technical Field

[0002] Transformers are crucial components of power systems, and their proper operation significantly impacts the safety of the power grid. Transformers are categorized as oil-immersed or dry-type based on insulation and cooling. To enhance insulation and cooling, the transformer's core and windings are immersed in a tank filled with transformer oil. When the voltage applied to the insulating oil exceeds a certain level, or when significant leakage current is generated under applied voltage, heating the insulation material can occur. This can lead to damage due to factors such as ionization and electrochemical reactions, resulting in a loss of insulation performance.

[0003] Deterioration of transformer insulating oil performance is a common problem. Breakdown resistance is a key testing indicator. Current testing methods rely on on-site oil sampling, requiring manual offline operation and inputting data into a testing device for testing.

[0064] Example 1

[0065] Figure 1 This is a flow chart of the insulating oil performance detection device based on power line carrier provided in the first embodiment of the present application. Figure 1 As shown, the specific steps include:

[0066] The remote control terminal 10 includes:

[0067] The remote control module 101 is used to receive control instructions for monitoring the performance of transformer insulating oil.

[0073] The second encoding and decoding module 201 is further configured to encode the performance detection result to obtain a second transmission signal.

[0074] The first encoding and decoding module 102 is further configured to receive the second transmission signal, decode the second transmission signal, obtain the performance detection result, and forward the result to the remote control module.

[0075] First, this solution can be used to test the performance of insulating oil. The device can be divided into a remote control end and a detection end. The detection end can be installed on the transformer equipment to be tested, and the remote control end can be installed at a specific location according to the needs.

[0076] Based on the above usage scenarios, it can be understood that the execution subject of this application can be an insulating oil performance testing device comprising a remote control terminal and a detection terminal, with the insulating oil performance testing device as a whole serving as the execution subject. In this solution, the remote control terminal and the detection terminal are included. The remote control terminal further includes a remote control module 101 and a first codec module 102; the detection terminal includes a second codec module 201, a detection module 202, and a result acquisition module 203.

[0077] Transformer insulating oil is the liquid insulating material used in oil-immersed transformers. Also known as transformer oil or square shed oil, insulating oil is a yellow, transparent liquid distilled from petroleum. Its primary function is to dissipate heat and cool the transformer, maintain insulation of the windings, and prevent corona and arc discharges.

[0078] Performance testing can examine the key electrical performance indicators of insulating oil. Key indicators include dielectric strength and the oil's dielectric loss tangent. Dielectric strength is expressed as its breakdown voltage under standard electrodes, expressed as average breakdown voltage (kV) or dielectric strength (kV / cm). Breakdown voltage refers to the voltage applied to a pair of electrodes placed in a container of insulating oil. When the voltage reaches a certain value, the current suddenly increases, sparking, and the insulating oil "breaks down." This voltage at which breakdown begins is called the "breakdown voltage." The breakdown voltage depends on many factors, such as the shape and size of the electrodes, the distance between them, and temperature; as well as the presence of moisture, acids, and other impurities in the oil. The better the performance of the insulating oil, the higher its breakdown voltage. Therefore, the breakdown voltage can be used to determine the electrical performance of the insulating oil. The principle behind the dielectric loss tangent is that when insulating oil is subjected to alternating current, it consumes some electrical energy and converts it into heat. This energy consumed per unit time is called dielectric loss. Dielectric loss occurs due to two factors: first, the polar molecules in the insulating oil are constantly in motion under the influence of an electric field, generating heat and causing electrical energy loss; second, leakage currents occur when current passes through the dielectric, causing current loss. This characteristic of insulating oil is often measured using the dielectric loss tangent. High-quality insulating oils generally have a low dielectric loss tangent. A higher dielectric loss tangent indicates greater electrical energy loss, or in other words, dielectric loss. Therefore, the dielectric loss tangent can be a very sensitive indicator of oil contamination.

[0079] In this solution, the performance indicators of the insulating oil are detected by installing a detection device on the transformer. The control instruction can be an instruction and command to direct the operation of the machine. Specifically, the control instruction can be generated by the remote control terminal. For example, the remote control terminal can be pre-installed with an intelligent chip, and a control instruction will be generated at a preset time. The instruction content can be a detection step sent to the detection device. The control instruction can also be a command issued by a staff member. For example, if a staff member needs to detect the performance of the insulating oil, he or she can enter a detection instruction at the remote control terminal. The detection instruction can include the detection steps and the detection time. Receiving an instruction can be the action of the remote control module 101 receiving the instruction after the instruction is generated. Specifically, after the staff member or the remote control terminal generates the instruction, the remote control module 101 receives the control instruction and then sends the instruction to other modules.

[0080] In the first codec module 102, power lines can be used as a medium for transmitting data and signals. Power line carrier communication (PLC) is a communication method unique to power system communication networks. It uses power lines as channels, substations and power plants as terminals, and high-voltage, medium-voltage, or low-voltage distribution lines as information transmission media for voice or data transmission. Specifically, the signal transmission process for PLC communication is as follows: the control command from the remote control end originally has a frequency of f1. The remote control end's carrier equipment uses amplitude modulation to convert it into a high-frequency signal with a frequency of f2, which is then transmitted over the power line. The detection end then receives and reverse-modulates the high-frequency signal f2 to obtain f1. Similarly, the detection end's signal can also be transmitted to the remote control end, thus achieving bidirectional PLC communication. The preset frequency range can be the original frequency range of the control command. The power line carrier frequency range is typically 40 to 500 kHz. In this solution, this can be adjusted based on demand. For example, if the preset frequency range is 40 to 150 kHz, the signal needs to be modulated into a high-frequency signal through amplitude modulation, which can be in the range of 340 to 450 kHz. The high-frequency signal reaches the detection end after being transmitted over the power line, where it is then converted back to its original frequency signal by a related modulator. The first transmission signal can be a signal converted from a control instruction encoded using a related encoding method. Specifically, the control instruction can be encoded using encoding methods such as return-to-zero, non-return-to-zero, and inverse non-return-to-zero, and then converted into a signal.

[0081] In this solution, the second codec module 201 can be connected to the first codec module 102 through a power line to achieve communication. Specifically, the second codec module can receive the first transmission signal sent by the remote control terminal and decode the first transmission signal. Decoding can be an operation of restoring the signal to data, and decoding is performed according to the selected encoding method. For example, if the return-to-zero code is selected during the encoding process, the rules of the return-to-zero code should also be used for decoding. Therefore, both the first codec module and the second codec module should include a power line carrier machine and a coupling device. The function of the power line carrier machine is to modulate and demodulate, move the signal to the high-frequency power line carrier communication frequency and move the signal from the high-frequency band back to the original frequency band. The main function of the coupling device is to pass the high-frequency carrier signal and organize the industrial frequency high voltage and tribute current on the power line to enter the carrier device to ensure personal safety and equipment safety.

[0082] In this solution, detection module 202 can be used to collect insulating oil from a transformer. Detection module 202 includes a specific container, a detection power supply, and an insulating oil delivery pipeline. The specific container can be an instrument for detecting insulating oil. Specifically, insulating oil is placed between two electrodes, and the power supply is activated to generate a potential difference between the two electrodes. The first and second electrodes can be positive and negative electrodes, respectively, and are not specifically defined here. The detection power supply can be the power supply within the detection module, which is used to energize the circuit and generate a specific potential difference. The potential difference can be the difference in potential between two points in an electric field, also known as voltage. Specifically, electrons, which are negatively charged, flow from the negative electrode of the power supply through an external circuit to the positive electrode of the power supply. For example, with the negative electrode as the reference point, the potential of the negative electrode is 0, and the potential of the positive electrode is assumed to be +50V, with both the voltage and potential difference being 50V. The detection principle can be to place a standard test electrode of a certain shape in the insulating oil, apply a power frequency voltage between the electrodes, and gradually increase the voltage at a certain rate until the oil gap between the electrodes breaks down. Alternatively, a voltage threshold can be set, meaning that if a certain voltage is reached without breakdown, the test is considered passed. For example, if the voltage threshold is set to 440V and the voltage between the electrodes does not break down at 440V, the test is considered passed. The voltage threshold here can be a specific voltage difference.

[0083] In this solution, the result acquisition module 203 is connected to the two electrodes. It can be used to obtain the current information between the two electrodes. Specifically, when the two electrodes are energized, current will be generated in the circuit, but because the insulating oil is not conductive, the current will be broken when it reaches the insulating oil. If the insulating oil is broken down, a path will be formed to display the current. For example, during the experiment, the voltage is increased little by little, but because the insulating oil is not broken down, the current is always zero. When the voltage is increased to a certain value and the insulating oil is broken down, the current will also display the relevant value. The performance test result can be a qualified test or a failed test. If the current is always zero in the process of increasing the voltage to the threshold, the test result is qualified. When the current displays a value when the voltage is increased to a certain value, it means that the test is unqualified. The performance test result can also include current and voltage data. For example, the insulating oil of transformer No. 1: No. 1, 440V, 0A, the test is qualified.

[0084] In this solution, the second transmission signal can be a signal obtained by encoding and converting the performance test results. Specifically, the performance test module sends the test results to the second encoding module 201. The second encoding module 201 converts the performance test results into a signal using a relevant encoding method, modulates the signal, and sends it to the first encoding module 102. The first encoding module 102 decodes the modulated signal and finally forwards the decoded performance test results to the remote control module 101.

[0085] In an embodiment of the present application, a remote control module 101 is configured to receive a control instruction for monitoring the performance of transformer insulating oil; a first encoding and decoding module 102 is configured to encode the control instruction into a first transmission signal according to a preset frequency range of a power line carrier; the detection end includes: a second encoding and decoding module 201, connected to the first encoding and decoding module via a power line, configured to receive the first transmission signal and decode the first transmission signal to obtain the control instruction; a detection module 202, configured to, based on the control instruction, inject insulating oil into a specific container and power a first electrode and a second electrode in the specific container via the detection power supply to form a specific potential difference between the first electrode and the second electrode; a result acquisition module 203, connected to the first electrode or the second electrode, configured to obtain current information of the first electrode or the second electrode and determine a performance test result of the insulating oil based on the current information; the second encoding and decoding module 201 is further configured to encode the performance test result to obtain a second transmission signal; and the first encoding and decoding module 102 is further configured to receive the second transmission signal and decode the second transmission signal to obtain the performance test result and forward it to the remote control module 101. By using the above-mentioned insulating oil performance detection device based on power line carrier, the insulating oil can be tested remotely, avoiding the shutdown operation of the transformer and ensuring the stable operation of the transformer.

[0087] Figure 2 This is a flow chart of the insulating oil performance detection device based on power line carrier provided in the second embodiment of the present application. Figure 2 As shown, the specific steps include:

[0088] The remote control terminal 10 includes:

[0089] The remote control module 101 is used to receive control instructions for monitoring the performance of transformer insulating oil.

[0090] The first encoding and decoding module 102 is configured to encode the control instruction into a first transmission signal according to a preset frequency range of the power line carrier.

[0091] The result display module 103 is connected to the remote control module and is used to display the performance test results.

[0092] The detection terminal 20 includes:

[0093] The second encoding and decoding module 201 is connected to the first encoding and decoding module via a power line, and is configured to receive the first transmission signal and decode the first transmission signal to obtain the control instruction.

[0094] The detection module 202 is configured to inject insulating oil into a specific container based on the control instruction, and supply power to the first electrode and the second electrode in the specific container through the detection power supply to form a specific potential difference between the first electrode and the second electrode.

[0095] The result acquisition module 203 is connected to the first electrode or the second electrode, and is used to obtain current information of the first electrode or the second electrode, and determine the performance test result of the insulating oil according to the current information.

[0096] The second encoding and decoding module 201 is further configured to encode the performance detection result to obtain a second transmission signal.

[0097] The first encoding and decoding module 102 is further configured to receive the second transmission signal, decode the second transmission signal, obtain the performance detection result, and forward the result to the remote control module.

[0098] The remote control module 101 is further configured to receive the result comparison instruction to retrieve a preset number of historical test results from pre-stored historical test data, and compare the performance test result with the preset number of historical test results.

[0099] The result display module 203 is also used to display the comparison results.

[0100] In this solution, the result display module 103 is connected to the remote control module. Among them, the result display module can be a display, which receives signals and forms images, and displays the performance test results on the screen. Specifically, the relevant interface connection can be selected for display. VGA (Video Graphics Array) interface and HDMI (High Definition Multimedia Interface) interface are usually used for display. VGA interface is a common interface. It is a color difference analog transmission interface. In addition, the VGA interface is also called D-Sub interface. HDMI is the most common and most common interface, which is widely used in home multimedia devices. It is a special digital interface suitable for image transmission, which can transmit audio and image signals at the same time.

[0101] In this solution, the remote control module 101 can also receive a result comparison instruction. This result comparison instruction can instruct the remote control module to compare test results. The comparison method can be to compare the overall fluctuation of the data and measure the changing trend of the data. Specifically, the storage method can be pre-installed in the remote control module. When the remote control module receives the instruction, it retrieves historical test results from the memory. The performance test results are then compared with the historical test results. To avoid data contingency, multiple historical test results can be retrieved. The preset number can be a pre-designed number of historical test data to be retrieved. Here, historical test data refers to the overall data of historical tests, and historical test results can be a preset number of data extracted from the overall data. The relationship between the two should be such that the former contains the latter. For example, the historical test results for this time may be 80, 220V, 60mA. The preset number is set to 5, and five samples are extracted from the historical test data: 2, 30, 45, 60, and 78. The extraction process should ensure the randomness of the samples. The voltage and current of each data point can be compared, and a function graph can be plotted to observe the degree of fluctuation.

[0102] In this solution, the comparison result can be the function graph drawn at last, or the comparison conclusion obtained through the function graph, which can be displayed on the result display module.

[0103] In this embodiment, the above embodiment is improved, specifically as follows: the remote control terminal further includes: a result display module 103, connected to the remote control module 101, for displaying the performance test results; the remote control module 101 is further configured to receive the result comparison instruction to retrieve a preset number of historical test results from pre-stored historical test data, and compare the performance test results with the preset number of historical test results; the result display module 103 is further configured to display the comparison results. By further explaining the remote control module and adding the result display module 103, the current performance test results can be better analyzed, further ensuring the stable operation of the transformer.

[0111] The detection module 202 is configured to inject insulating oil into a specific container based on the control instruction, and supply power to the first electrode and the second electrode in the specific container through the detection power supply to form a specific potential difference between the first electrode and the second electrode.

[0112] The result acquisition module 203 is connected to the first electrode or the second electrode, and is used to obtain current information of the first electrode or the second electrode, and determine the performance test result of the insulating oil according to the current information.

[0113] The insulating oil returning module 204 is configured to return the insulating oil in the specific container after obtaining the performance test result of the insulating oil, so as to return the insulating oil to the transformer.

[0114] The second encoding and decoding module 201 is further configured to encode the performance detection result to obtain a second transmission signal.

[0115] The first encoding and decoding module 102 is further configured to receive the second transmission signal, decode the second transmission signal, obtain the performance detection result, and forward the result to the remote control module.

[0116] In this solution, the insulating oil return module 204 can function within the testing module. To ensure proper operation of the transformer, the tested insulating oil can be returned to the transformer after the testing module completes its testing. Qualified products can be directly returned to ensure normal transformer operation. Unqualified products can be returned with the option of replacing the insulating oil.

[0117] Based on the above technical solutions, optionally, the detection end further includes:

[0118] Insulating oil infusion pipeline and insulating oil return pipeline.

[0119] The insulating oil infusion pipeline is provided with an infusion motor, and the insulating oil return pipeline is provided with a cleaning motor.

[0120] In this embodiment, the inspection module 202 may include an infusion pipe and a return pipe. The infusion pipe is used to transport the insulating oil to be inspected from the transformer to a specific container. The return pipe is used to return the inspected insulating oil to the transformer. One end of the infusion pipe and the return pipe are connected to the transformer, and the other end is connected to the inspection module. Specifically, the infusion pipe and the return pipe can be directly connected to the specific container.

[0121] In this solution, the motor can be a small electric motor or engine. The operating principle is that the energized coil rotates in a magnetic field, driving the starter rotor, which in turn rotates the engine flywheel. When the detection end receives a test command, the infusion pipeline begins to infuse the motor, transferring insulating oil to a specific container. When the test is complete, the return pipeline opens to purge the motor and return the insulating oil to the transformer.

[0122] In this embodiment, the detection terminal 202 is further described. It is equipped with relevant pipes and a motor. This eliminates the need for manual collection and return of test samples, allowing the detection terminal to automatically obtain insulating oil samples. This allows the transformer to operate normally during the test process, improving the stability of transformer operation.

[0123] On the basis of the above technical solutions, optionally, the insulating oil detection module of the detection end is arranged inside or outside the transformer.

[0124] In this solution, detection module 202 can be located inside or outside the transformer. Regardless of location, detection module 202 and the transformer are connected via an infusion pipe and a return pipe. The specific location of detection module 202 can be determined based on specific needs and is not specifically defined here.

[0125] In this embodiment, the position relationship between the detection module and the transformer is further explained. The position scheme can be selected according to one's own needs. Both schemes are based on the normal operation of the transformer, avoiding the transformer shutdown operation and improving the stability of the transformer operation.

[0126] In the embodiments of the present application, improvements are made to the above-described embodiments. Specifically, an insulating oil return module is configured to return the insulating oil in the specified container to the transformer after obtaining the insulating oil performance test results. The addition of the insulating oil return module addresses post-test sample processing. By returning the insulating oil from the pipeline, the need to manually shut down the transformer is avoided, eliminating the need to shut down the transformer and ensuring stable operation of the transformer.

[0133] The detection terminal 20 includes:

[0134] The second encoding and decoding module 201 is connected to the first encoding and decoding module via a power line, and is configured to receive the first transmission signal and decode the first transmission signal to obtain the control instruction.

[0140] The first encoding and decoding module 102 is further configured to receive the second transmission signal, decode the second transmission signal, obtain the performance detection result, and forward the result to the remote control module.

[0141] The information storage module 104 can be a memory built into the remote control terminal, mainly used to store data. Specifically, the location information and attribute information of the transformer can be stored. The location information can be the location information of the transformer, which can be stored in coordinates. The attribute information can be information describing the nature or characteristics of the transformer, such as the name and number of the transformer, whether it is in working condition, and the working age of the transformer. When the preset time interval is reached, for example, the identity information of the transformer is checked every other day. The remote control module 101 can send an application to the information storage module 104, and the application content can be to read the information of the transformer. The attribute information of the transformer can be used to analyze which transformers need to be tested, and then the location information and name and number of the transformer that needs to be tested are sent to the detection terminal, and the detection terminal will test the transformer.

[0142] This solution improves upon the aforementioned embodiment. Specifically, the remote control module 101 is further configured to issue an information acquisition instruction when the performance test result is the target result. The remote control terminal also includes an information storage module 204 for storing the transformer's location and attribute information. Upon receiving the address acquisition instruction, the remote control module provides feedback to the remote control module on the transformer's target information based on the location and attribute information. By further specifying the remote terminal and adding the information storage module, data placement issues are better addressed, enabling the detection terminal to more quickly locate the transformer to be detected, further improving detection efficiency.
