Product Description

 

Product 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.

It 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.

Features


1.    Acquisition and control using high-speed, highly integrated microprocessor.
2.    Communication USB interface used between a laptop and instrument.

3.    The communication between the laptop and the instrument can use wireless Bluetooth interface or wireless WIFI interface (optional)

The wireless WIFI interface can be conveniently used on tablet computers and smart phones.
4.    Hardware adopts dedicated DDS digital high-speed scanning technology (USA), which can accurately diagnose the faults like winding distorted, bulged, shift, tilt, inter-turn short-circuit deformation and inter-phase contact short-circuit.

5.    High-speed dual-channel 16-bit A/D sampling (in field test, move tap changer, and the wave curve shows obvious change) .

6.    The signal output amplitude is adjusted by software, the maximum amplitude peak value is ±10V.
The computer will automatically analyze the test results and generate electronic documents (Word)
7. The instrument has dual measurement features: linear frequency scanning measurement and segment frequency scanning measurement, compatible with measurement mode of two technical groups in China 

8. The amplitude-frequency characteristics are in line with the national technical specifications on amplitude-frequency characteristics tester. X-coordinate (frequency) has linear indexing and logarithmic indexing, so you can print out the curve with linear indexing and logarithmic indexing. The user can choose either according to actual needs.

9.Compare between A, B, C -phases in winding similarity comparison, and
the analysis results are:
excellent consistency
good consistency
poor consistency
rather poor consistency


Compare winding deformation by calling the original data and comparing it with the current data of the same phase, namely A-A, B-B, C-C, 
and the analysis results are:
normal winding
mild deformation
moderate deformation
severely deformation

10.Word electronic document can be automatically generated for saving and printing.
11. The instrument can fully meet the technical requirements of electricity standard DL/T911-2004 "Transformer winding deformation frequency response analysis".

Features of use
1. The transformer winding deformation tester consists of a measurement part and an analysis software part. The measurement part is controlled by a high-speed microcontroller and consists of signal generation and signal measurement. The measurement part is connected to a tablet computer through a wireless WIFI interface, which requires no wiring and is easy to use. Wireless Bluetooth and USB interfaces can also be used to connect to a tablet or laptop computer.

2. During the test process, only the connecting busbar of the transformer needs to be removed, and all tests can be completed without hanging the cover or disassembling the transformer.

3. The instrument has a variety of frequency linear sweep measurement system measurement functions. The linear sweep measurement scanning frequency is up to 10MHz. The frequency sweep interval can be divided into 0.25kHz, 0.5kHz and 1kHz, providing more analysis of the transformer deformation.

4. The instrument is highly intelligent, easy to use, and has multiple functions such as automatic range adjustment and automatic sampling frequency adjustment.

5. The software uses the windows platform and is compatible with Win98/2000/WinXP/Win7/Win8/Win10 systems. Provides users with a more convenient and easy-to-use display interface.

6. Provides comparative analysis of historical curves, can load multiple historical curves for observation at the same time, and can specifically select any curve for horizontal and vertical analysis. Equipped with an expert intelligent analysis and diagnosis system, it can automatically diagnose the status of the transformer winding, load 6 curves at the same time, automatically calculate the relevant parameters of each curve, automatically diagnose the deformation of the winding, and provide reference conclusions for diagnosis.

7. The software management function is powerful, fully considering the needs of on-site use, and automatically saving environmental condition parameters to provide a basis for diagnosing transformer winding deformation. The measurement data is automatically saved and has a color printing function to facilitate users to produce test reports.

8. The software has obvious humanization features. Most of the measured conditions are options. The detailed parameters of the transformer can be saved for diagnostic reference, and there is no need to input them on site. Information can be added and modified later, making it more convenient to use.

9. The software is highly intelligent. After the input and output signals are connected and the condition parameters are set, all measurement work can be completed, and historical waveform curves can be opened during measurement at any time for comparison and observation and to stop measurement.

10. The measurement time of each phase is less than 60 seconds, and the total time required for winding deformation measurement of a power transformer with high, medium or low windings (no limit on capacity and voltage level) is no more than 10 minutes.

11.When measuring the transformer, the wiring personnel can place the signal input and output leads arbitrarily without affecting the measurement results. The wiring personnel can stay on the transformer tank without coming down, which reduces labor intensity.
