Description

Technical Field

[0001] This invention relates to the field of power equipment testing technology, and more specifically, to an integrated testing system for power transformers, which solves the problems of modular design, cumbersome manual operation, and low data processing efficiency in traditional testing systems. Background Technology

[0002] In smart grids, power transformers serve as high-voltage isolation devices and perform ratio-based current and voltage conversion, providing current and voltage signals with accurate proportional relationships to the primary circuit for electrical measurement, energy metering, and automation devices. They also provide signals and high-voltage isolation for instruments and relay protection. Their metering accuracy, operational stability, and equipment reliability directly affect the safe and economical operation of the power grid; therefore, regular insulation performance testing, error verification, and characteristic tests are necessary to ensure the accuracy of measurement data and the reliability of protection device operation.

[0003] In the field of electrical testing, the traditional testing of instrument transformers currently uses separate and independent testing equipment, which mainly presents the following technical problems:

[0004] 1. Existing technological pain points:

[0005] Currently, traditional power transformer testing projects generally employ discrete testing equipment, leading to several technical challenges that urgently need to be addressed. First, the modular design necessitates frequent wiring changes for different testing items. For example, voltage ratio testing and dielectric loss measurement require separate connections to different instruments, resulting in low efficiency and posing a risk of electric shock or short circuits due to repeated plugging and unplugging under high voltage and high current conditions. Second, the testing process is highly dependent on manual operation. From equipment switching and parameter setting to data recording, manual intervention is required, extending the testing cycle and potentially causing data deviations due to operational errors. Furthermore, data management is siloed, with acquisition, processing, and storage processes disconnected, lacking a unified platform to integrate historical data, making it difficult to achieve retrospective analysis of test results, trend analysis, and equipment status assessment. These problems severely restrict the improvement of testing efficiency and the intelligent development of power equipment operation and maintenance.

[0006] 2. Technological gaps:

[0007] Within the existing technological framework, significant technological gaps remain in the field of power transformer testing. Firstly, the lack of integrated intelligent matrix switch interfaces prevents the automatic adaptation of signal path switching for multiple test items with a single wiring connection, making it difficult to eliminate the problem of repetitive wiring. Secondly, the automation level of the testing process is insufficient; test sequence optimization, anomaly protection, and fault isolation still require manual intervention, failing to achieve full-process control. Thirdly, the application of intelligent data is inadequate; an integrated system covering data acquisition, real-time analysis, templated report generation, and historical data mining has not yet been established, requiring manual comparison of test results with standard templates, which is time-consuming and prone to errors. These technological gaps limit further improvements in testing efficiency and hinder the power industry's transformation and upgrading towards standardization and intelligentization. Summary of the Invention

[0008] To address the problems of modular separation, repetitive wiring, cumbersome manual operation, and inefficient data management in traditional testing techniques, this invention proposes an integrated testing system for power transformers.

[0009] The present invention provides an integrated test system for power transformers, comprising a physical interface layer, a signal processing layer, an energy supply layer, and an intelligent control layer;

[0010] The physical interface layer integrates a quick-connect module, which is configured as a standardized interface matrix. The standardized interface matrix includes multiple standardized interfaces, which are plugged and plugged into test points corresponding to multiple test items of the power transformer to enable testing of multiple test items of the power transformer.

[0011] 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, and the multiple switch interface modules are connected one-to-one with multiple test instrument units. The test signal after the test items of the power transformer are performed is transmitted to the corresponding test instrument unit through the corresponding switch interface module.

[0012] The energy supply layer is equipped with an adaptive power supply module. The adaptive power supply module dynamically matches the power supply parameters of the test project 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 also integrates an overload protection mechanism.

[0013] The intelligent control layer is equipped with a host computer module, which receives the test signals transmitted by the test instrument unit, analyzes the test signals, and automatically generates test reports.

[0014] Based on the above technical solution, the present invention can also be improved as follows.

[0015] Optionally, the standardized interface matrix is ​​configured as multiple multi-pin high-voltage withstand slots, which are connected to the test points of multiple test items of the power transformer.

[0016] Optionally, the plurality of multi-pin high-voltage withstand slots are configured with different color codes for differentiation and are equipped with magnetic positioning and spring locking mechanisms to ensure close contact with the test points of multiple test items of the power transformer.

[0017] Optionally, the inner side of the intelligent matrix switch interface module integrates multiple input / output interfaces, which are connected one-to-one with multiple test instrument units. The multiple input / output interfaces are controlled to be switched on and off by multiple switch interface modules. The outer side of the intelligent matrix switch interface module is connected to the quick wiring module through a high-speed communication bus.

[0018] Optionally, the intelligent matrix switch interface module is configured as a multiplexed switch matrix.

[0019] Optionally, the intelligent matrix switch interface module is used to control the switching order of multiple switch interface modules according to the order of multiple test items of the power transformer sent by the host computer module, so as to automatically switch the test signal path and transmit the test signal of the power transformer to the corresponding test instrument unit through the switched test signal path.

[0020] Optionally, the adaptive power module has a built-in overload protection mechanism;

[0021] The adaptive power supply module is used to activate the built-in overload protection mechanism and cut off the power supply to the intelligent matrix switch interface module according to the protection command sent by the host computer module. Specifically, when the host computer module analyzes the test signal and finds it to be abnormal, it sends a protection command to the adaptive power supply module.

[0022] Optionally, the host computer module is used to automatically compare the test signals of the power transformer with the standard test signals in the preset standard template using template matching technology, identify deviations, and generate a compliance report.

[0023] This invention provides an integrated testing system for power transformers. Through a modular, layered architecture, it integrates quick wiring, intelligent matrix switching, adaptive power supply, and host computer control modules. This enables one-time wiring and automated signal switching for multiple test items, eliminating the safety hazards and efficiency bottlenecks of repeated manual wiring. Simultaneously, the system uses a host computer to uniformly schedule the test process, dynamically optimize the execution sequence, and integrates data acquisition, analysis, storage, and report generation functions, forming a closed-loop data management system that improves testing efficiency and result reliability. Furthermore, the system supports historical data backtracking and intelligent analysis, providing a basis for equipment condition assessment and fault diagnosis. Ultimately, this system promotes the transformation and upgrading of power transformer testing from a fragmented and manual process to an intelligent and integrated one, meeting the urgent needs of the power industry for efficient, safe, and standardized testing.

[0027] Figure 1 The present invention provides an integrated testing system for power transformers, such as... Figure 1 As shown, the integrated test system for power transformers includes a physical interface layer, a signal processing layer, an energy supply layer, and an intelligent control layer.

[0028] The physical interface layer integrates a quick-connect module, which is configured as a standardized interface matrix. The standardized interface matrix includes multiple standardized interfaces, which are plugged and plugged into test points corresponding to multiple test items of the power transformer to enable testing of multiple test items of the power transformer.

[0029] 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, and the multiple switch interface modules are connected one-to-one with multiple test instrument units. The test signal after the test items of the power transformer are performed is transmitted to the corresponding test instrument unit through the corresponding switch interface module.

[0030] The energy supply layer is equipped with an adaptive power module. The adaptive power module dynamically matches the power supply parameters of the test project 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 module integrates an overload protection mechanism and supports hot-swapping and redundant configuration.

[0031] The intelligent control layer is equipped with a host computer module, which receives the test signals transmitted by the test instrument unit, analyzes the test signals, and automatically generates test reports.

[0032] It is understood that the integrated power transformer testing system provided by the present invention is based on a modular layered architecture design. Through the collaborative work of the physical interface layer, signal processing layer, energy supply layer and intelligent control layer, it realizes automated testing and intelligent management of multiple test items of power transformers.

[0033] The integrated power transformer testing system adopts a modular, layered architecture, mainly consisting of the following four layers of collaborative components:

[0034] Physical Interface Layer: Deploys quick-connect modules that connect to the test points (primary and secondary windings, etc.) of the power transformer via a standardized interface matrix (such as multi-pin high-voltage withstand sockets). The standardized interface matrix includes multiple standardized interfaces, each configurable as a multi-pin high-voltage withstand socket. The power transformer has multiple test items, each corresponding to a test point (e.g., current test point, voltage test point). Each standardized interface connects to one test point on the power transformer to perform testing for each of the power transformer's test items.

[0035] Signal processing layer: Configured with intelligent matrix switch interface module, which is connected to the physical interface layer through high-speed communication bus (such as RS-485). Its input terminal is connected to the current transformer test signal, and its output terminal is connected to multiple test instrument units.

[0036] Understandably, the intelligent matrix switch interface module includes multiple switch interfaces. One side connects to the physical interface layer via a high-speed communication bus to receive test signals for a specific test item from the power transformer. The other side of the intelligent matrix switch interface module connects to multiple test instrument units via multiple switch interfaces to transmit the test signals for a specific test item to the corresponding test instrument unit for acquisition. The test instrument unit then sends the acquired test signals to the host computer module of the intelligent control layer.

[0037] Intelligent control layer: The host computer module interacts with other layers via Ethernet or wireless communication protocols, and has a built-in customized software platform to achieve full-process automated control.

[0038] Understandably, the host computer module controls the intelligent matrix switch interface module, multiple test instrument units, and the adaptive power supply module. 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 sequentially to connect to the test instrument units for the acquisition of corresponding test signals.

[0039] Energy Supply Layer: The adaptive power module provides power to each layer of the system through an independent power supply line. The power output terminal is connected to the intelligent matrix switch and test instruments, supports dynamic adjustment of output power supply parameters, and provides excitation power to the power transformer through the quick wiring module and the intelligent matrix switch interface module, while providing stable power to other modules of the system.

[0040] The host computer module analyzes the test signals collected by the test instrument unit. When an abnormality occurs in the test signal, it controls the adaptive power supply module to cut off the power supply to the intelligent matrix switch interface module. Since different test items for power transformers require different voltage levels, the adaptive power supply module can also dynamically match different power supply parameters according to the different test items of the power transformer, providing power excitation to match the different test items of the power transformer.

[0041] The following describes each layer of the integrated power transformer testing system provided in the embodiments of the present invention.

[0042] (1) Quick-connect module:

[0043] The quick-connect module is the core physical connection unit of the integrated power transformer testing system. It features a high-voltage, high-current compatible design, capable of withstanding voltages up to several kilovolts and high-current testing environments, ensuring safety and stability. By integrating the various test interface matrices of the transformer, this module unifies the traditionally separate wiring requirements into standardized plug-in interfaces, achieving "one-time wiring, multi-item coverage." Furthermore, the quick-connect module employs an anti-misinsertion design and a mechanical locking mechanism to further reduce the risk of wiring errors, significantly improve testing efficiency, and ensure operational safety under high-voltage environments. It is suitable for complex scenarios such as substations and laboratories.

[0044] The quick-connect module's interface design utilizes high-voltage (≥10kV) alloy contacts, integrating interfaces for seven common transformer test items. Color coding and anti-misconnection grooves prevent incorrect connections. The quick-connect interface features magnetic positioning and a spring-locking mechanism to ensure tight contact after wiring, preventing poor contact under high loads.

[0045] Operating procedure: The tester inserts the primary side, secondary side and grounding terminal of the current transformer into the corresponding slots at once to complete the physical connection of multiple test items.

[0046] (2) Intelligent matrix switch interface module:

[0047] The intelligent matrix switch interface module is the signal path control center of the system. It integrates a programmable high-precision switch matrix, connecting externally to the test points (such as primary and secondary windings) and control points of the power transformer, and internally integrating input / output interfaces for various test instrument units. Driven by host computer commands, this module analyzes test requirements in real time and automatically switches the conduction paths of the switch matrix to ensure accurate matching of current and voltage signals for different tests to the corresponding instrument channels. Simultaneously, the module supports multi-channel parallel testing, enabling simultaneous signal acquisition and analysis of multiple tests, improving the efficiency of traditional serial testing. It also features self-checking and fault isolation mechanisms to ensure system reliability.

[0048] The intelligent matrix switch interface module is configured with a multiplexed switch matrix driven by an FPGA or microcontroller, supporting switching of at least 32 signal channels, with each channel having a withstand voltage rating that matches the test requirements.

[0049] Multi-channel parallel testing: Different test signals (such as current and voltage) are distributed to independent channels through host computer instructions, and multiple test items are executed simultaneously.

[0050] Fault self-checking mechanism: The module periodically scans the conduction status of each channel. If a short circuit or open circuit is detected, it immediately reports to the host computer and isolates the faulty channel.

[0051] (3) Adaptive power supply module:

[0052] The adaptive power supply module provides dynamic and intelligent energy supply to the system, adjusting output voltage, current, and power parameters in real time according to the needs of the test projects. Different levels of excitation power are matched to different test projects for the power transformers. Therefore, the adaptive power supply module dynamically matches the power supply parameters of the test projects, providing excitation power to the power transformers through quick-connect modules and intelligent matrix switch interface modules, while simultaneously providing stable power to other modules in 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 protection commands issued by the host computer, quickly cutting off the power supply and isolating the faulty interface to prevent equipment damage or safety accidents. Furthermore, the power supply module adopts a modular design, supporting hot-swapping and redundant configuration. While ensuring power supply continuity, it adapts to the flexible expansion needs of different test scenarios, significantly improving the system's applicability and reliability.

[0053] Dynamic power supply matching: Based on the power supply requirements of different types of test projects, the output parameters are adjusted in real time (voltage range: 0-10kV, current range: 0-30A).

[0054] Overload protection mechanism: It integrates voltage surge 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.

[0055] Redundant configuration: It adopts a dual power supply parallel design, supports hot-swappable replacement, and the backup power supply can seamlessly take over when the main power supply fails, ensuring test continuity.

[0056] (4) Host computer module:

[0057] The host computer module serves as the system's intelligent control and data processing center, achieving fully automated management based on a customized software platform. In terms of process control, the module optimizes the test sequence through algorithms, automatically triggering test procedures and monitoring execution status, reducing manual intervention. For data processing, after real-time acquisition of test data, it automatically compares the results with preset standard templates using template matching technology, identifies deviations, and generates comprehensive compliance reports with graphics and text, supporting one-click export to PDF or Excel formats. Regarding historical data management, the module constructs a structured database for long-term storage of test data and operation logs, supporting data backtracking and trend analysis to provide data support for operational decisions. Furthermore, the host computer provides a human-machine interface, supporting remote monitoring and parameter configuration, realizing the intelligentization, standardization, and scalability of the testing system.

[0058] Software platform design for the host computer module: The control interface is developed based on LabVIEW or Python, integrating test process management, data acquisition, analysis and report generation functions.

[0059] Full-process automation: In terms of test sequence optimization, the test order is automatically sorted according to the test type of the power transformer, reducing equipment switching time; in terms of data acquisition and processing, the test signals from the test instrument unit are received in real time and automatically compared and analyzed with the standard test signals. The comparison results are filled into a standardized template to generate a PDF report containing waveforms, data tables and conclusions, which can be exported with one click; in terms of historical data management, an SQL database is built to store test records, which can be retrieved by time, equipment number or test item type, and relevant machine learning algorithms are used to analyze data trends and provide early warning of potential equipment failures.

[0060] See Figure 2 The diagram below illustrates the testing workflow of the integrated power transformer testing system provided in this embodiment of the invention. First, after the wiring of each module is completed, the host computer module sends instructions, which include the test sequence of multiple test items for the power transformer. The intelligent switch interface matrix parses the instructions from the host computer module, switches the test signal channels, and the adaptive power supply module supplies power to each model and starts the test according to the instructions from the host computer module.

[0061] The corresponding testing instrument unit collects the test signals from the power transformer and uploads them to the host computer module. The host computer module analyzes, processes, and stores the test signals. Specifically, the host computer module analyzes the test signals; if the test signal is abnormal, a protection mechanism is triggered, and the host computer module sends a protection command to the adaptive power supply module. Based on the protection command, the adaptive power supply module cuts off power to the intelligent switch matrix module, which then isolates the fault point. If the test signal is normal, a test report is generated based on the test signal.

[0062] This invention provides an integrated testing system for power transformers. Through highly integrated and intelligent design, it significantly improves the efficiency, safety, and data management capabilities of power transformer testing, specifically in the following aspects:

[0063] (1) Significantly improved testing efficiency: The quick-connect module adopts a standardized interface matrix, which completes the physical connection of multiple test items at once, completely eliminating the drawback of repeated wiring required by traditional split systems. 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 automated control, further reducing manual intervention and improving resource utilization.

[0064] (2) Significantly enhanced safety and reliability: The anti-misinsertion design and high-voltage withstand structure of the quick-connect module, as well as the fault self-checking function of the intelligent matrix switch, jointly ensure the safety of operation under high voltage and high current environments.

[0065] (3) Intelligent and standardized data management: The host computer module automatically generates test reports that conform to industry standards through template matching technology and supports one-click export of standardized formats.

[0066] (4) System flexibility and scalability optimization: The power supply 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 provides open remote monitoring and parameter configuration interfaces to adapt to diverse scenarios such as substations and laboratories, providing a scalable platform for intelligent testing of power equipment.
