The frequency conversion transformer comprehensive tester is a powerful power testing equipment, mainly used for comprehensive testing of current transformers (CT) and voltage transformers (PT) to ensure the reliable operation of power grid equipment. The specific problems that this tester can solve mainly include the following aspects:
① Excitation characteristic test: Measure the volt ampere characteristic curve of the transformer and evaluate its saturation characteristics. The tester can intuitively display key parameters such as saturation point and inflection point voltage of the transformer, helping staff understand the excitation performance of the transformer.
② Ratio test: Measure the ratio of the transformer to ensure its accuracy. This is particularly important for protection and measurement transformers, as the accuracy of the transformation ratio directly affects the protection and measurement accuracy of the power system.
③ Polarity test: Measure the polarity of the transformer to ensure that the phase of the secondary output signal is correct. This helps ensure that the relay protection device can operate correctly and prevent misoperation or refusal due to phase errors.
④ Secondary winding resistance test: Measure the resistance value of the secondary winding and evaluate its insulation condition. Through testing, potential faults such as inter turn short circuits can be discovered, improving the safety of the equipment.
⑤ Secondary load test: Simulate the secondary side load and test the output capability of the transformer. This helps to verify the performance of the transformer under actual loads, ensuring that it can meet the operational requirements of the power system.
⑥ Ratio and angle difference test: measure the ratio and angle difference between multiple transformers to evaluate the coordination of the system. This helps ensure data consistency between multiple transformers, improving the measurement accuracy and stability of the power system.
In addition, the comprehensive tester for variable frequency transformers also has the following characteristics, further enhancing its ability to solve problems:
① Fully functional: In addition to the basic testing functions mentioned above, the tester can also perform multiple tests such as demagnetization, primary current detection, phase measurement (angle difference), ratio difference measurement, secondary winding resistance measurement, and secondary actual load measurement, achieving multi-purpose use of one machine.
② Easy to operate: The tester uses a rotating mouse and a large LCD display, making the operation simple and intuitive. At the same time, it supports data storage and on-site printing functions, making it convenient for staff to record and compare.
③ High precision and efficiency: The tester adopts advanced testing techniques and algorithms, which can accurately and quickly complete various testing tasks. At the same time, it also has a large capacity FLASH storage function, which can store a large amount of experimental data for easy subsequent analysis and processing.
In summary, the comprehensive testing instrument for variable frequency transformers can solve various testing problems of transformers in the power system, ensuring the reliable operation of power grid equipment. It has a wide range of application value in the maintenance, repair, design, installation, experimentation, and testing of power systems.
