The invention discloses a distributed fiber sensor arrangement structure comprising a winding. A first optical fiber and a second optical fiber are arranged at the outer side of the winding. The firstoptical fiber is fixed on the winding through a mounting bracket. The second optical fiber is adhered to the winding by an insulating adhesive tape; and a thermal-insulation layer coats the outer side of the second optical fiber. The mounting rack includes a housing fixed at the winding; a support plate is coupled inside the housing; one end of the support plate is in contact with the winding andthe other end of the support plate is in contact with the first optical fiber; and the first optical fiber is fixed at the housing by two buckles. A plurality of fixed points are arranged at the second optical fiber; and two insulated adhesive tapes are fixed at each fixed point in an intersected manner. According to the invention, defects in the prior art are overcome; and the precision of the transformer winding detection by the fiber sensor is improved.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to a distributed optical fiber sensor arrangement structure. Background technique [0002] In the research practice and engineering application of transformer winding deformation detection at home and abroad, the winding deformation state is mainly evaluated based on the relative changes in the electrical parameters, physical size, geometric shape, temperature and other characteristic quantities of the transformer winding when deformation occurs. After a lot of theoretical analysis and experimental research by researchers at home and abroad, the main detection methods of winding deformation are mainly divided into two categories: offline detection and online detection. The mainstream methods of off-line detection include short-circuit impedance method, frequency response method and low-voltage pulse method. The mainstream method of online detection is the vibration method. ...
