Sweep Frequency Response Analyzer XHBX1501
Description
The XHBX1501 transformer winding deformation tester (frequency
response method) is used to test power transformers of 6KV and
above and other special purpose transformers.
XHBX1501 transformer winding deformation tester uses the frequency
response analysis method to measure the winding deformation of the
transformer according to the national power industry standard
DL/T911-2004. It is to detect the amplitude-frequency response
characteristics of each winding of the transformer and compare the
detection results vertically or horizontally. The degree of change
in the amplitude-frequency response characteristic determines the
deformation that may occur in the transformer winding.
The XHBX1501 transformer winding deformation tester (frequency
response method) consists of a measurement part and an analysis
software part. The measurement part is a black box composed of
signal generation and signal measurement. The analysis part is
completed by a notebook computer, and the measurement part is
connected to the notebook computer via USB or network.
Main 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,
The analysis results are:
① consistency is very good
② good consistency
③ poor consistency
④ consistency is very poor,
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,
The analysis results are:
① normal winding
② mild deformation
③ moderate deformation
④ severe 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.
