Description

Technical Field

[0001] The present invention relates to the technical field of power equipment detection, and more specifically, to an integrated power transformer test system for solving the problems of discrete modules, cumbersome manual operations, and low data processing efficiency in traditional test systems. Background Art

[0002] In smart grids, power transformers (PTs) provide high-voltage isolation and ratiometric current and voltage conversion, providing current and voltage signals accurately proportional to the primary circuit for electrical measurement, energy metering, and automation devices. They also provide signals and high-voltage isolation for instrumentation and relay protection. Their measurement accuracy, operational stability, and equipment reliability directly impact the safety and economic operation of the power grid. Therefore, regular quality control measures such as insulation performance testing, error correction, and characteristic testing are essential to ensure the accuracy of measurement data and the reliability of protective device operation.

[0003] In the field of electrical testing, traditional transformer test projects are currently carried out using discrete, independent testing equipment, which mainly has the following technical problems: 1. Pain points of existing technologies: Currently, traditional power transformer test projects generally use discrete testing equipment, resulting in multiple technical pain points that need to be addressed urgently. First, the discrete module design requires frequent wiring changes for different test projects. For example, voltage ratio testing and dielectric loss measurement require separate connection to different instruments. This is not only inefficient, but also poses the risk of electric shock or short circuits when repeatedly plugging and unplugging wiring in high-voltage, high-current environments. Secondly, the test process is highly dependent on manual operation. From equipment switching, parameter setting to data recording, manual intervention is required, which not only prolongs the test cycle, but may also lead to data deviations due to operational errors. In addition, data management is "islanded", with the collection, processing and storage links disconnected from each other. There is a lack of a unified platform to integrate historical data, making it difficult to trace test results, analyze trends, and evaluate equipment status. These problems have seriously restricted the improvement of test efficiency and the development of intelligent operation and maintenance of power equipment.

[0004] 2. Technology gaps: Within the existing technical framework, there are still significant technological gaps in the field of power transformer testing. First, there is a lack of an integrated intelligent matrix switch interface, which makes it impossible to automatically adapt the signal path switching of multiple test items through a single wiring, resulting in the problem of repeated wiring being difficult to solve. Second, the degree of automation of the test process is insufficient, and test sequence optimization, abnormal protection and fault isolation still require manual intervention, making it impossible to achieve full process control. Third, there are shortcomings in the application of intelligent data. An integrated system covering data collection, real-time analysis, templated report generation and historical data mining has not yet been established. Test results still need to be manually compared with standard templates, which is time-consuming and error-prone. These technical gaps limit the further improvement of testing efficiency and hinder the transformation and upgrading of the power industry towards standardization and intelligence. Summary of the Invention

[0018] Figure 1 The present invention provides an integrated power transformer test system, such as Figure 1 As shown, the integrated power transformer test system includes a physical interface layer, a signal processing layer, an energy supply layer and an intelligent control layer.

[0019] The physical interface layer integrates a quick wiring module, the quick wiring module is configured as a standardized interface matrix, the standardized interface matrix includes a plurality of standardized interfaces, and the plurality of standardized interfaces are pluggably connected to test points corresponding to a plurality of test items of the power transformer to implement testing of the plurality of test items of the power transformer; The signal processing layer is configured with an intelligent matrix switch interface module. The intelligent matrix switch interface module has a built-in programmable high-precision switch matrix. The switch matrix includes multiple switch interface modules. The multiple switch interface modules are connected to multiple test instrument units in a one-to-one correspondence. The test signals after the test items of the power transformer are tested are transmitted to the corresponding test instrument units through the corresponding switch interface modules. The energy supply layer is configured with an adaptive power supply module, which dynamically matches the power supply parameters of the test items of the power transformer and provides excitation power to the power transformer through the quick wiring module and the intelligent matrix switch interface module. The adaptive power supply module integrates an overload protection mechanism and supports hot plugging and redundant configuration; The intelligent control layer is configured with a host computer module, which receives the test signal transmitted by the test instrument unit, analyzes the test signal, and automatically generates a test report.

[0020] It can be understood that the integrated power transformer test system provided by the present invention is based on a modular layered architecture design, and realizes the automated testing and intelligent management of multiple test items of the power transformer through the collaborative work of the physical interface layer, signal processing layer, energy supply layer and intelligent control layer.

[0021] The integrated power transformer test system adopts a modular layered architecture, mainly including the following four layers of collaborative components: Physical interface layer: Deploy quick-connect modules and connect them to the power transformer's test points (primary and secondary windings, etc.) through a standardized interface matrix (such as multi-pin, high-voltage sockets). The standardized interface matrix includes multiple standardized interfaces, each of which can be configured as a multi-pin, high-voltage socket. A power transformer has multiple test items, each corresponding to a test point (for example, current or voltage). Each standardized interface connects to a test point on the power transformer to test each test item.

[0022] Signal processing layer: Configure the intelligent matrix switch interface module, which is connected to the physical interface layer through a high-speed communication bus (such as RS-485). Its input end is connected to the transformer test signal, and its output end is connected to multiple test instrument units.

[0023] It can be understood that the intelligent matrix switch interface module includes multiple switch interfaces, one side of which is connected to the physical interface layer via a high-speed communication bus to receive test signals for a specific test item of the power transformer. The other side of the intelligent matrix switch interface module is connected to multiple test instrument units via multiple switch interfaces to transmit the test signals of a specific test item to the corresponding test instrument unit for collection. The test instrument unit then sends the collected test signals to the host computer module of the intelligent control layer.

[0024] Intelligent control layer: The upper computer module interacts with other layers through Ethernet or wireless communication protocols, and has a built-in customized software platform to achieve full-process automated control.

[0025] It is understood that the host computer module controls the intelligent matrix switch interface module, multiple test instrument units, and adaptive power supply module separately. For example, the host computer module can set the test sequence for multiple test items of the power transformer and control the switch matrix in the intelligent matrix switch interface module to switch and connect to the test instrument units in sequence to collect the corresponding test signals.

[0026] Energy supply layer: The adaptive power supply module provides power to each layer of the system through independent power supply lines. The power output end is connected to the intelligent matrix switch and test instruments, supporting dynamic adjustment of output power supply parameters. It also provides excitation power for the power transformer through the quick wiring module and the intelligent matrix switch interface module, and provides stable power for other modules of the system.

[0027] The host computer module analyzes the test signals received from the test instrument unit. If any abnormality is detected, it controls the adaptive power supply module to cut off power to the intelligent matrix switch interface module. Because different power transformer test items require different voltage levels, the adaptive power supply module can dynamically match power supply parameters to the test items, providing power excitation to the transformer to match the different test items.

[0028] Each layered architecture of the integrated power transformer test system provided by the embodiment of the present invention is described below.

[0029] (1) Quick wiring module: The quick-connect module is the core physical connection unit of the integrated power transformer test system. It utilizes a high-voltage, high-current compatible design, capable of withstanding voltages up to several thousand volts and high-current testing environments, ensuring safety and stability. By integrating the transformer's various test project interface matrices, the module unifies traditional discrete wiring requirements into standardized plug-in interfaces, achieving "one-time wiring, multiple project coverage." Furthermore, the quick-connect module utilizes an anti-misplug design and a mechanical locking mechanism to further reduce the risk of wiring errors, significantly improve testing efficiency, and ensure operational safety in high-voltage environments. It is suitable for complex scenarios such as substations and laboratories.

[0030] The quick-connect module's interface design utilizes high-voltage (≥10kV) alloy contacts and integrates connectors for the standard Category 7 transformer test items. Color-coding and anti-mistakable grooves prevent misconnection. The quick-connect interface features magnetic positioning and a spring-loaded locking mechanism to ensure secure contact after wiring, preventing poor contact under high loads.

[0031] Operation process: The tester inserts the primary side, secondary side and grounding terminals of the transformer into the corresponding slots at one time to complete the physical connection of multiple test items.

[0032] (2) Intelligent matrix switch interface module: The intelligent matrix switch interface module serves as the system's signal path control hub. It features a built-in programmable, high-precision switch matrix. Externally, it connects to the power transformer's test points (such as the primary and secondary windings) and control points, while internally integrating the input and output interfaces of various test instrument units. Driven by host computer commands, the module analyzes test project requirements in real time and automatically switches the conduction paths of the switch matrix, ensuring precise matching of current and voltage signals for different tests to corresponding instrument channels. Furthermore, the module supports multi-channel parallel testing, enabling simultaneous signal acquisition and analysis of multiple projects, improving the efficiency of traditional serial testing. Self-test and fault isolation mechanisms ensure reliable system operation.

[0033] The switch matrix configuration of the intelligent matrix switch interface module: a multiplexed switch matrix driven by FPGA or microcontroller is used to support switching of at least 32 signal channels, and the voltage withstand level of each channel matches the test requirements.

[0034] Multi-channel parallel testing: Different test signals (such as current and voltage) are assigned to independent channels through host computer instructions, and multiple test items are executed synchronously.

[0035] Fault self-checking mechanism: The module periodically scans the conduction status of each channel. If a short circuit or open circuit is detected, it will immediately report to the host computer and isolate the faulty channel.

[0036] (3) Adaptive power module: The adaptive power supply module provides a dynamic and intelligent energy supply for the system, and can adjust the output voltage, current, and power parameters in real time according to the requirements of the test project. Specifically, different levels of excitation power are matched to different test projects of the power transformer. Therefore, the adaptive power supply module dynamically matches the power supply parameters of the test project, provides excitation power to the power transformer through the quick wiring module and the intelligent matrix switch interface module, and provides stable power to other modules of the system. The adaptive power supply module has a built-in multi-level overload protection mechanism. When abnormal data is detected, it can respond to the protection instructions issued by the host computer, quickly cut off the power supply and isolate the faulty interface to prevent equipment damage or safety accidents. In addition, the power supply module adopts a modular design and supports hot-swappable and redundant configuration. While ensuring power supply continuity, it adapts to the flexible expansion requirements of different test scenarios, significantly improving the applicability and reliability of the system.

[0037] Dynamic power supply matching: Based on the power supply requirements of different types of test projects, output parameters are adjusted in real time (voltage range: 0-10kV, current range: 0-30A).

[0038] Overload protection mechanism: integrated voltage mutation suppression circuit, current limiting protection chip and power fuse, when overvoltage or overcurrent is detected, the power supply is cut off in a short time.

[0039] Redundant configuration: Dual power supplies in parallel are designed to support hot-swap replacement. When the main power supply fails, the backup power supply takes over seamlessly to ensure test continuity.

[0040] (4) Host computer module: The host computer module is the intelligent control and data processing center of the system, and realizes full-process automated management based on a customized software platform. In terms of process control, the module optimizes the test sequence through algorithms, automatically triggers the test process and monitors the execution status, reducing manual intervention. In terms of data processing, after collecting test data in real time, template matching technology is used to automatically compare the results with the preset standard template, identify deviations and generate compliance reports with pictures and texts, and support one-click export to PDF or Excel format. In terms of historical data management, the module builds a structured database for long-term storage of test data and operation logs, supports data backtracking and trend analysis, and provides data support for operation and maintenance decisions. In addition, the host computer provides a human-computer interaction interface, supports remote monitoring and parameter configuration, and realizes the intelligence, standardization and scalability of the test system.

[0041] Software platform design of the host computer module: Develop the control interface based on LabVIEW or Python, integrating test process management, data acquisition, analysis and report generation functions.

[0042] Full process automation: In terms of test sequence optimization, the test type of the power transformer is automatically sorted to reduce equipment switching time; in terms of data acquisition and processing, the test signal of the test instrument unit is received in real time and automatically compared and analyzed with the standard test signal. The comparison results are filled into the standardized template, and a PDF report containing waveforms, data tables and conclusions is generated, which supports one-click export; in terms of historical data management, an SQL database is built to store test records, supporting retrieval by time, equipment number or test item type, and using relevant machine learning algorithms to analyze data trends and warn of potential equipment failures.

[0043] See also Figure 2 The following diagram illustrates the test workflow of the integrated power transformer test system provided by an embodiment of the present invention. First, after wiring of each module is completed, the host computer module sends a command, which includes the test sequence for multiple power transformer test items. The intelligent switch interface matrix parses the host computer module's command and switches the test signal channel. The adaptive power supply module then powers each model according to the host computer module's command and initiates the test.

[0044] The corresponding test instrument unit collects the test signal from the power transformer and uploads it to the host computer module, which analyzes, processes, and stores it. The host computer module analyzes the test signal. If it detects abnormal data, it triggers a protection mechanism and issues a protection command to the adaptive power module. Based on the protection command, the adaptive power module cuts off power to the intelligent switch matrix module, which isolates the fault point. If the test signal is normal, a test report is generated based on the test signal.

[0045] The integrated power transformer test system provided by the present invention significantly improves the efficiency, safety, and data management capabilities of power transformer testing through a highly integrated and intelligent design, which is specifically reflected in the following aspects: (1) Significantly improved test efficiency: The quick wiring module uses a standardized interface matrix to complete the physical connection of multiple test items at one time, completely eliminating the disadvantage of traditional split systems requiring repeated wiring. The intelligent matrix switch interface module automatically adapts to different test signal paths through a programmable switch matrix. The host computer module optimizes the test sequence and realizes full process automation control, further reducing manual intervention and improving resource utilization.

[0046] (2) Safety and reliability are significantly enhanced: the anti-misinsertion design and high-voltage-resistant structure of the quick wiring module, as well as the fault self-detection function of the intelligent matrix switch, jointly ensure operational safety in high voltage and high current environments.

[0047] (3) Intelligent and standardized data management: The host computer module automatically generates test reports that meet industry standards through template matching technology, and supports one-click export to a standardized format.

[0048] (4) System flexibility and scalability optimization: The power module can dynamically adapt to the power supply requirements of different test scenarios, and the intelligent matrix switch supports flexible expansion of instrument units. The host computer opens remote monitoring and parameter configuration interfaces, adapting to diverse scenarios such as substations and laboratories, providing an expandable platform for intelligent testing of power equipment.
