Product Description

Product Description

According to the measurement of the characteristic parameters of the internal winding of the transformer, the XHBX1502 transformer winding deformation tester adopts the internal fault frequency response analysis (FRA) method developed by the developed countries in the world, which can make an accurate judgment on the internal fault of the transformer.
 

The XHBX1502 transformer winding deformation tester quantifies the response changes of the internal winding parameters of the transformer in different frequency domains, and determines the internal transformer according to the magnitude of the change, the magnitude of the frequency response change, and the change of the regional and frequency response. The degree of change of the winding, and then can be judged according to the measurement results whether the transformer has been seriously damaged and whether it needs to be overhauled.

Features

1. Adopt control uses high-speed, high-integration microprocessor.
2. Communication USB port between laptop and instrument.
3.Wireless Bluetooth port (optional) for communication between laptop and instrument.
4. The hardware movement adopts DDS special digital high-speed frequency sweeping technology (USA), which can accurately diagnose faults such as twisting, bulging, displacement, tilting, inter-turn short-circuit deformation and phase-to-phase contact short-circuit.
5. high-speed dual-channel 16-bit A / D sampling (field test to change the tap-changer, the waveform curve has a clear change).
6. The signal output amplitude software adjustment, the maximum amplitude peak is ± 10V.
7. The computer will automatically analyze the test results and generate e-documents (Word)
8. The instrument has the functions of linear sweep frequency measurement and segmented sweep frequency measurement dual measurement system, which is compatible with the current domestic two technical genre measurement modes.
9. The amplitude-frequency characteristic is in line with the national technical indicators of the amplitude-frequency characteristic tester. The abscissa (frequency) has two types of linear indexing and logarithmic indexing. Therefore, the printed curve can be a linear indexing curve or a logarithmic indexing curve, and the user can select according to actual needs.
10.Automatic data analysis system for detection data, Horizontal comparison of winding similarities between A, B, and C phases,Longitudinal comparison A-A, B-B, C-C take the original data and the current data in the same phase to compare the winding deformation
11. Can automatically generate Word e-documents for saving and printing.
12. The instrument fully meets the technical requirements of the power standard DL/T911-2004 "Frequency Response Analysis Method for Winding Deformation of Power Transformers".
