Optical fiber composite insulator prefabricated core rod, mold and manufacturing method of optical fiber composite insulator prefabricated core rod

Abstract

The invention discloses an optical fiber composite insulator prefabricated core rod, a mold and a manufacturing method of the optical fiber composite insulator prefabricated core rod. The optical fiber composite insulator prefabricated core rod comprises a core rod body, a silicone rubber layer and at least one optical fiber. The silicone rubber layer is integrally formed on the outer cylindricalsurface of the core rod body in an injection molding mode, and the silicone rubber layer is annular; at least one optical fiber is arranged outside the core rod body, the middle of the optical fiber is embedded in the silicone rubber layer, and one end or two ends of the optical fiber extends / extend out of the rubber layer. The optical fiber and the core rod body are fixed through vacuum injectionmolding of silicone rubber to form a silicone rubber outer coating layer, air gaps are prevented from being generated on the interfaces of the optical fiber, the silicone rubber layer and the core rod, and the problem that the performance and the service life of the optical fiber composite insulator are seriously affected due to bubble defects generated in the optical fiber bonding process duringmanual manufacturing of the optical fiber composite insulator can be overcome.

Description

technical field [0001] The invention relates to the field of on-line monitoring of power transmission and transformation equipment, in particular to an optical fiber composite insulator prefabricated core rod, a mold and a manufacturing method thereof, which are suitable for optical fiber composite insulators above 110kV. Background technique [0002] The insulator is one of the key equipment in the power system, and its working status affects the safe operation of the power grid. Composite insulators are widely used in my country's power grid lines, and can be divided into rod-shaped suspension composite insulators and line post composite insulators. The rod-shaped composite insulator has a light and simple structure, convenient manufacturing process, strong tensile strength resistance, non-breakdown, and excellent pollution resistance. The line post composite insulator has a relatively fixed shape, simple overall structure, strong bending load capacity, non-breakdown, and...
