Abstract

The invention provides a sensing optical fiber and current-carrying conductor integrated combined wire and a preparation process thereof. The sensing optical fiber and current-carrying conductor integrated combined wire comprises a plurality of stacked conductors, a plurality of optical fibers and a common insulating layer, wherein a wire groove is formed in the surface of at least one conductor along the axial direction, and each optical fiber is embedded in the corresponding wire groove through an adhesive; the surface of each conductor is wrapped with a first insulating layer, the conductors are stacked to form a conductor group, and the common insulating layer wraps the surface of the conductor group. According to the sensing optical fiber and current-carrying conductor integrated combined wire provided by the invention, the sensing optical fiber and the current-carrying conductor are accurately bonded together, so that the information, such as the temperature and deformation on the current-carrying conductor, etc., can be accurately transmitted through the optical fiber; the structure is simple, the mechanical performance is good, the application range is wide, and the large-scale application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of power transformer winding wires, in particular to a combined wire in which a sensing optical fiber and a current-carrying conductor are integrated and a preparation process thereof. Background technique [0002] As a key equipment, power transformers have always been research hotspots for intelligent monitoring of state quantities such as temperature and deformation. However, they are generally measured indirectly through external sensors, and there are application limitations caused by sensor life and operation and maintenance. Through the research on the sensing technology and application of transformer winding temperature and strain, the problem of integrated technology and preparation process of combined wire and optical fiber sensor is solved, and the direct measurement of temperature and strain inside the transformer is realized, and the transformer coil temperature rise, me...
