ZXXC-5A power transformer demagnetization analyzer is a special equipment to eliminate the remanence of large power transformers, with demagnetization and verification demagnetization functions. It plays a very important role in protecting the transformer from the impact of inrush current, safe operation and prolonging transformer life.
Technical features:
1. Adopting the new compound current demagnetization method, the current impact is small in the demagnetization process.
2. High demagnetization efficiency, only one phase of the three-phase transformer can be eliminated, greatly saving time.
3. Manual demagnetization and automatic demagnetization.
4. It has the function of initial remanence detection and remanence detection after demagnetization. The demagnetization and remanence measurement can be completed by one connection.
5. The demagnetizing progress percentage and demagnetizing progress indicator bar are intuitive, and the remanence rate is quantified.
6. Simple wiring, direct use of DC resistance test line for demagnetization.
7. Digital current adjustment, high precision current control.
8. 5-inch color touch screen control, easier to operate, system interface can be switched between Chinese and English.
9. Automatic storage of test results, complete record of data before and after demagnetization, no manual storage.
10. The report can be printed directly and stored in a USB disk.
11. The analysis software management is humanized and highly intelligent. After setting the parameters, all the measurement work can be completed by pressing a key.
12. The software interface is simple and intuitive, and the menus such as analysis, storage, report export and printing are clear at a glance.
Analysis software features:
1. Using embedded system, no risk of software poisoning.
2. Using directory to save test data, the management of test data is simple and convenient.
3. The test system can print data directly.
4. Supports usb flash drive data export.
5. The software has a high degree of intelligence. After the input and output signals are connected, you only need to press a key. Complete all measurements.
7. The software interface is simple, intuitive and practical.
