Audited Supplier Fully automatic Transformer ratio group polarity tester/Transformer turns ratio TTR tester
Product overview
Our company independently developed, developed and produced multi-functional automatic ratio tester in addition to different according to the user's field requirements, simple operation, complete functions, stable and reliable data characteristics, or can carry out blind testing (do not know any of the nameplate parameters of the transformer under test accurately measure the ratio and group number, and can accurately measure the phase Angle) ratio tester; Can adapt to the needs of large, small and medium transformer ratio test (including Z-type change, rectification, electric furnace change, non-integral shift phase change, traction change, Scott and reverse Scott transformer), the test project is perfect, comprehensive measurement parameters of the ratio tester.
KDB-IV transformer ratio tester uses a large screen color liquid crystal as a display, Chinese graphical operation interface and is equipped with Chinese prompt information, multi-parameter display LCD interface, human-machine dialogue interface friendly, vector graph display and connection judgment for checking the correctness of the circuit provides a reliable basis. Touch type conductive silicone keyboard operation mode, operation feel good, easy to learn.
The instrument has built-in large capacity data memory without loss of power failure, which can save the on-site verification data, and can expand the storage of up to 1000 sets of on-site verification results. The background microcomputer management software can be provided, and the results can be transferred to the computer through the U disk, and the production report and printing can achieve microcomputer management.
KDB-IV transformer ratio tester adopts the engineering plastic shell designed and manufactured by our company, which is beautiful and practical in appearance. Field testing is easy to operate.
Fully automatic Transformer ratio group polarity tester/Transformer turns ratio TTR tester
Functional characteristics
1, the real three-phase test: single-phase power input, the internal digital synthesis of three-phase standard sine wave signal source, through the high-fidelity power amplifier, produce three-phase test power supply (distortion less than 0.1%, symmetry better than 0.05%) output, the test results are good, there will be no group misjudgment and other phenomena
2, strong function: both single-phase measurement, but also can realize the automatic test of three-phase winding, single-phase, three-phase can measure polarity, phase Angle, a complete measurement of AB, BC, CA three-phase variable ratio, phase Angle value, error, tap position, tap value and other parameters, can automatically identify the group number.
3. Phase Angle measurement function: accurately measure the phase Angle between the high and low voltage sides, and can measure the ratio and Angle of the transformer for non-integral points.
4, hexagonal diagram display function: the test results are displayed in digital and hexagonal vector diagram, which can visually see the transformer connection group.
5, blind test function: no need to choose the wiring mode, no need to choose the wiring group, measurement Y/△, △/Y transformer without external shorting, can automatically switch the wiring mode according to the selected test content. It is possible to measure the ratio and group number of a transformer without a nameplate.
6, tap-changer test: can quickly measure the ratio and ratio error at each tap-changer position, rated ratio only need to be entered once, do not have to enter repeatedly to calculate the ratio error at each tap-changer position.
7, at the same time with the number of turns ratio measurement and operating voltage ratio measurement of two functions, the operating ratio can more truly reflect the transformer in the actual operation of the case, the actual value of the voltage ratio.
8. Good vibration resistance: The use of military connectors enhances the vibration resistance.
9, using 5.6 inch HD true color LCD screen, display data effect and vector image effect intuitive and delicate.
10, the test source used in this instrument is a standard sine digital source of digital synthesis, the distortion is less than 0.1%, not affected by the quality of the working power supply.
11, easy to carry: small size, light weight.
12, optional high-capacity lithium-ion rechargeable battery, on-site without power to complete the test work, a full can be continuous more than 800 measurements.
