TKCTP-1000B variable frequency transformer comprehensive tester is based on the traditional transformer volt-ampere characteristic transformation ratio polarity comprehensive tester based on voltage regulator, booster, and current transformer, and is widely used for listening
A new generation of innovative CT and PT testing instruments developed after extensive market research and in-depth theoretical research. The device uses high-performance DSP and FPGA, advanced manufacturing technology,
It ensures stable and reliable product performance, complete functions, high degree of automation, high test efficiency, and a leading level in the country. It is a professional testing instrument for transformers in the power industry.
The frequency conversion type transformer comprehensive tester meets the following occasions:
1. Suitable for transformer calibration of electric power research institutes;
2. It is suitable for factory calibration by transformer manufacturers;
3. Meet the preventive test of the power sector;
4. Meet the handover test of engineering units and panel enterprises.
1. Comprehensive functions, which not only meet the excitation characteristics (ie volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, and ratio difference of various CTs (such as protection, measurement, TP)
It can also be used to test the excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference and other test requirements of various PT electromagnetic units;
2. On-site verification of current transformers does not require standard current transformers, current transformers, load boxes, voltage regulating control boxes, and large current wires. Simple test wiring and operation are used to achieve current transformers
The verification reduces the work intensity and improves the work efficiency, and facilitates the on-site verification of transformers;
3. It can accurately measure the ratio difference and the angle difference, the maximum allowable error of the ratio difference is ±0.1%, and the maximum allowable error of the angle difference is ±5min. It can carry out the field test of the 0.2S current transformer, and the measurement range of the transformation ratio
1～35000;
4. After selecting and matching our company's dedicated current booster, it can output a current of 180A, which is convenient for on-site current flow test;
5. Test the CT/PT volt-ampere characteristic curve and 10% error curve based on the advanced frequency conversion method. The maximum output is only 180V AC voltage and 12Arms (36A peak) AC current, but it can cope with the inflection point.
CT test up to 60KV;
6. The inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence factor (Kr), saturation are automatically given and
CT and PT parameters such as unsaturated inductance;
7. The test meets various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and which standard is automatically selected according to the type and level of the transformer
carry out testing;
8. The test is simple and convenient. The direct resistance, excitation, transformation ratio and polarity test of CT can be completed with one key. In addition to the load test, all other CT tests use the same wiring method;
9. Full Chinese dynamic graphic interface, you can complete wiring and set parameters without referring to the manual: dynamic display parameter settings, automatically display related parameters according to the currently selected test item;
Status display help wiring diagram, according to the currently selected test item, display the corresponding wiring diagram;
10.5.7-inch graphic transflective LCD, clearly visible in the sun;
11. It adopts rotating optical mouse to operate, which is simple, fast and convenient, and easy to master;
12. The panel comes with a printer, which can automatically print the generated test report;
13. The device can store 1000 sets of test data, which will not be lost after power failure;
14. Easy to carry, the weight of the device is less than 9Kg.
