TKRZ-5001 Transformer Winding Deformation Tester

TKRZ-5001 Transformer Winding Deformation Tester, based on the measurement of the characteristic parameters of the transformer's internal windings, adopts the internal fault frequency response analysis that is currently being developed in developed countries in the world.

(FRA) method, can make accurate judgments on the internal fault of the transformer. After the transformer is designed and manufactured, its coil and internal structure are determined, so for a multi-winding transformer coil

If the voltage level is the same and the winding method is the same, the corresponding parameters (Ci, Li) of each coil should be determined. Therefore, the frequency domain characteristic response of each coil is also determined, and the corresponding three-phase line

There is a certain degree of comparability between the frequency maps; the transformer has a short circuit between turns and phases during the test, or a collision occurs during transportation, which causes the relative displacement of the coil, and the relative displacement of the coil during the operation.

Under short-circuit and fault conditions, the deformation of the coil due to electromagnetic tension will change the distribution parameters of the transformer winding. Then affect and change the original frequency domain characteristics of the transformer, that is, the frequency response occurs

Amplitude changes and resonant frequency shifts, etc. The transformer winding tester developed based on the response analysis method is such a novel non-destructive testing equipment for transformer internal faults. It works for

63kV～500kV power transformer internal structure fault detection.

       The transformer winding deformation tester is to quantify the response changes of the internal winding parameters of the transformer in different frequency domains, according to the magnitude of the change, the amplitude, area and frequency of the frequency response change.

To determine the degree of change in the internal windings of the transformer according to the changing trend of the transformer, and then determine whether the transformer has been severely damaged and whether it needs to be overhauled according to the measurement results. For running

Regardless of whether the frequency domain characteristic map is saved in the past, the fault degree can also be judged by comparing the difference of the characteristic map between the faulty transformer coils. Of course, if you save

A set of original winding characteristic diagrams of the transformer can provide a more accurate and powerful basis for the operation status of the transformer, post-accident analysis, and maintenance and repair.
