Abstract
As an important equipment in the power system, the safe operation of the transformer directly affects the safety of the power grid. Winding deformation is a common cause of transformer faults. The monitoring of winding deformation is an important research content in transformer condition monitoring. However, there is currently no effective monitoring method for transformer winding deformation. With the rise of distributed optical fiber sensing technology, the optical fiber sensing technology based on Brillouin scattering technology is used to complete the real-time monitoring of winding deformation by laying optical fiber outside the winding wire. The optical fiber composite wire model and the built-in optical fiber 35 kV winding model were prepared under laboratory conditions. Four kinds of direction deformation were applied to the wire model to explore the feasibility of the sensing technology. The winding model was artificially deformed, and the Brillouin frequency shift curve of the optical fiber before and after deformation was compared. The effectiveness of distributed optical fiber sensing technology in measuring winding deformation was successfully verified.
