Abstract

The invention discloses a high-reliability optical fiber composite insulator, which includes a core rod, a skeleton, a first heat insulating layer, a shed and fittings, the core rod includes an optical fiber cured body, a second heat insulating layer and a core rod body layer, and the optical fiber cured body is Epoxy resin rod, the epoxy resin rod is provided with at least two optical fibers arranged in the axial direction and spaced from each other, the second heat insulating layer is coated and cured outside the optical fiber cured body, and the core rod body layer is coated and cured on the second insulating layer In addition, the skeleton is a number of epoxy resin rings that are solidified on the outer peripheral surface of the mandrel at intervals in the axial direction. The first heat insulating layer is coated and cured outside the skeleton and filled to connect adjacent epoxy resin rings. The shed is covered and cured on the Each umbrella surface is formed outside the first heat insulating layer and at the position of the epoxy resin ring, the first heat insulating layer is made of glass fiber, and the second heat insulating layer is made of glass fiber mixed with silicate. The invention also discloses a preparation method of curing sequentially from the inside to the outside. The invention solves the problem that the optical fiber inside the insulator is broken due to external high temperature and traction force, resulting in failure and affecting the service life.

Description

technical field [0001] The invention relates to an insulator and a preparation method thereof, in particular to a high-reliability optical fiber composite insulator and a preparation method thereof. Background technique [0002] Composite insulators are a special insulation control that can play an important role in overhead transmission lines. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guaranteed. Insulators should not fail due to various stresses caused by changes in the environment and electrical load conditions, otherwise It will damage the service life and operating life of the entire line. The combination of composite insulators and optical fibers can realize monitoring, information collection and transmission under high voltage, and facilitate the safe operation and timely maintenance of power transmission and transformation lines.
