characteristics
1.Transformer winding deformation tester consists of measurement part and analysis software part. The measurement part is high speed single chip microcomputer control, which is composed of signal generation and signal measurement. The measurement part is connected with the tablet computer by the wireless Bluetooth interface, without wiring, easy to use, and can also be connected with a tablet computer or a notebook computer by using the USB interface.
2.In the test process, only need to remove the transformer connection bus, without the transformer hanging cover, disassembly and completion of all tests.
3.Instruments have a variety of linear sweep frequency measurement frequency measurement system, linear sweep frequency measurement of scanning frequency up to 10MHz, frequency scanning interval can be divided into 0.25kHz, 0.5kHz and 1kHz, to provide more analysis of deformation of transformer.
4.Intelligent instrument, easy to use, automatic range adjustment, automatic sampling, frequency regulation and other functions.
5.Software adopts windows platform and is compatible with windows98/2000/winXP/Windows7 system. A more convenient and easy to use display interface is provided for users.
6.Provide historical curve contrast analysis, may simultaneously load several historical curves to observe, can select any curve to carry on the crosswise and the longitudinal analysis specifically. With the analysis of expert intelligent diagnosis system, which can automatically diagnose the transformer winding, while loading the 6 curves, automatically calculate the related parameters of each curve, automatic winding deformation diagnosis, diagnostic reference conclusions are given.
7.Software management is powerful, fully considering the needs of field use, automatic preservation of environmental parameters, in order to provide the basis for transformer winding deformation diagnosis. The measurement data is automatically saved and has the function of color printing, which is convenient for users to give out test reports.
8.Humanization software features, conditions of measuring more options, with transformer parameters can be stored for diagnosis, and not at the scene can later add input, modify the information, more convenient to use.
9.Software is a high degree of intelligence, after connected in the input and output signals, set the parameters, you can complete all of the measurements, and can open the historical wave curves are compared with observation and measurement in the measurement stop.
10.Each phase measuring time is less than 60 seconds, for a high, medium and low winding power transformer (capacity, voltage level is not limited) for winding deformation measurement, the total time does not exceed 10 minutes.
11.When measuring the transformer, the wiring staff can arbitrarily output the signal input and output lead, and have no influence on the measurement result. The wiring personnel can stay on the transformer oil tank, and do not need to come down to reduce the labor intensity.
