    Automatic Transformer Winding Deformation Test Equipment

     

     

    I. Introduction:

    Since the structure and reference of transformer are fixed after being made, the frequency response of each winding is almost same normally.

    Some cases ,such as cut off between circles or phases in experience, cut off or winding moved for the pull of power in running, winding moved for hit in transportation, could change the reference of the transformer ,of which the frequency response will be changed, we could detect the deformation according to the frequency response curve.

    Our company has designed the winding deformation tester based on the idea and the advanced technique.

    SFRA-I Transformer Winding Deformation Test Equipment can draw the frequency response curve accurately. Then we compare the curves horizontally or vertically to detect the deformation of the transformer.

    And this winding deformation test equipment is conformed to the standard of DL/T911 2004.

     

    II.Main Features

    1. Using the advanced technical of DDS;

    2. Using the high speed and advanced microprocessor to design;

    3. Using double channels of AD chip of 16 bits;

    4. With seven inch LCD touch screen of which the brightness can be adjusted;

    5. With thermal printer of which the print thick can be adjusted;

    6. SFRA transformer winding deformation test equipmentcould store 40 groups of data, which could be read to current screen or upload to the PC;

    7. With PC software using which we could upload data ,test, analyze data, print data, or create word document;

    8. Using USB2.0 to connect to the device;

    9. Tester dimension:31cm X 15cm X 15cm;

    10. Weight:4.0KG;

    11. SFRA transformer winding deformation test equipment is conformed to the standard of DL/T911 2016 and can be used for IEC60076-18:2012.
