High pressure resistant insulation supporting post containing tightly packaged fiber as well as manufacture and application thereof

Abstract

The present invention discloses a high-voltage resistant insulation strut comprising tight coated fibers, and a manufacture and an application thereof, belonging to the technical field of the high-voltage resistant insulation strut in electrical power transmission and the manufacture and application thereof. The insulation strut comprises an epoxy core rod, sealing fasteners, tight coated fibers, epoxy resin, an insulation sleeve and cushioning liquid cement. The two ends of the epoxy core rod are provided with a sealing fastener respectively, and the epoxy core rod is provided with a groove which runs through the two ends. Two tight coated fibers are parallelly arranged in the groove. The two ends of each tight coated fiber traverse through end surfaces of the two sealing fasteners respectively. The groove is filled with the cushioning liquid cement. The epoxy core rod is arranged in the insulation sleeve in such a manner that the central axis is overlapped with the central axis of the insulation sleeve. A space among the top of the cushioning liquid cement, the epoxy core rod and the insulation sleeve is filled with the epoxy resin. The strut has the advantages of high insulation performance index, high mechanical strength, good local discharge and voltage resistance performance and the performance of the tight coated fiber being not affected by outside stress. Particularly, the strut is suitable for being used as a data transmission channel for a high-voltage current transformer.

Description

technical field [0001] The present invention relates to a kind of high-voltage resistant insulation pillar containing tight-packed optical fiber and its manufacture and application. The technical field of high-voltage resistant insulation pillar in transportation and its manufacture and application. Background technique [0002] Optical fiber is the abbreviation of optical fiber waveguide or optical fiber. Its traditional structure is a cylinder and multiple cladding layers attached to its surface in turn. From the center to the outside are the core, cladding and coating. [0003] The core part is the core and the cladding. The core is made of highly transparent material and is the main transmission channel for light waves; the refractive index of the cladding is slightly smaller than that of the core, making the light transmission performance relatively stable. The thickness of the core, the refractive index of the core material and the cladding material have a decisive in...

AI Technical Summary

Problems solved by technology

[0012] Although the above three insulating pillars contain tight-packed optical fibers, they all have the following defects: in the preparation process of the insulating pillar, epoxy resin needs to be poured into the inner space of the insulating pillar, and after the epoxy resin is cured, the resulting Stress, acting on the tight-packed fiber, has a bad influence on the tight-packed fiber, making it uneven in thickness, resulting in a decrease in the stability of the polarization transmission performance of the tight-packed fiber

Strictly speaking, the tight-packed optical fibers sealed in the above-mentioned insulating pillars are no longer suitable for data transmission channels of high-voltage current transformers.
