Product Details
I. System Introduction
HM5010 Fra Transformer Winding Deformation Tester is used to test power transformers with voltage levels of 6kV and above and other special-purpose transformers. Power transformers are inevitably subject to various fault short-circuit currents or physical shocks during operation or transportation. Under the action of the generated strong electromotive force, the transformer windings may lose stability, causing permanent deformation such as partial distortion, bulging or displacement, which will seriously affect the safe operation of the transformer.
According to the international standard IEC60076-18, the frequency response analysis method is used to measure the winding deformation of the transformer. It is by detecting the amplitude-frequency response characteristics of each winding of the transformer, and comparing the detection results longitudinally or laterally, and judging the transformer according to the degree of change of the amplitude-frequency response characteristics The possible deformation of the winding.

III. Main technical features
1. Fra Transformer Winding Deformation Tester uses the sweep frequency method to measure the winding characteristics of the transformer. Without hanging the transformer cover, disassembling and disassembling the transformer, by detecting the amplitude-frequency response characteristics of each winding, it can accurately measure the winding distortion for transformers of 6kV and above. , Bulge, or displacement.
2. The measurement speed is fast, and the measurement time for a single winding is within 2 minutes, and three-phase automatic testing can be realized.
3. The frequency accuracy is very high, the frequency accuracy is 0.001%.
4. Using digital frequency synthesis, the frequency stability is higher.
5. Adopt 5000V voltage isolation to fully protect the safety of the test computer.
6. 9 curves can be loaded at the same time, the relevant parameters of each curve are automatically calculated, the deformation of the winding is automatically diagnosed, and the reference conclusion of the diagnosis is given.
7. The analysis software used by Fra Transformer Winding Deformation Tester is powerful, and the software and hardware indicators meet the international electrotechnical standard IEC60076-18.
8. Using Windows platform, compatible with Windows 2000/Windows XP/Windows7/Windows8/Windows10.
9. Adopt the database to save the test data, and the management of the test data is simple and convenient.
10. The software management function is powerful, fully considering the needs of on-site use. The measurement data is automatically saved and exported to generate a Word version test report (corresponding Office software needs to be installed) or a JPG picture report, which is convenient for users to produce test reports.
11. The software has a high degree of intelligence. After the input and output signals are connected, all measurement tasks can be completed by pressing a key.
12. The software interface is simple and intuitive. The analysis, storage, report export, printing and other menus can automatically pop up the menu required for the next step only after completing the current step, which is more convenient.
