A large tonnage multi-channel optical fiber composite insulator

Abstract

A large-tonnage multi-channel optical fiber composite insulator is characterized in that two end of a core rod are respectively crimped with two connection fittings, and that two connection fittings have the same structure and are oppositely installed; The connecting fitting is of hollow structure, one end of the connecting fitting is crimped with the core rod, and the other end of the connectingfitting is screwed with the outer fitting cavity. An epoxy cylinder is arranged on one end of the connecting fitting and the mandrel and on the outer sleeve of the wound silicone rubber belt. An umbrella skirt is arrange on that outer surface of the epoxy barrel, and an optical fib channel hole is provided on the connecting fitting, the optical fib channel hole is communicated with a gap between the connecting fitting and the epoxy barrel, and is communicated with an external fitting, and is communicated with an optical fiber channel hole of another oppositely installed connecting fitting through a gap between the connecting fitting and the epoxy barrel. The large-tonnage multi-channel optical fiber composite insulator adopts two kinds of connection of the core rod and the epoxy cylinder to form the double insulation and can improve the performance of the insulator. A plurality of optical fibers are implanted into the gap between the core rod and the fitting, so that the number of lightning flashover can be recorded, and the data can be transmitted to a designated position through the optical fibers.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, and relates to a large-tonnage multi-channel optical fiber composite insulator. Background technique [0002] In the power system, generators, transformers, and insulators are the three main components. Insulators run through every link in power transmission and transformation. According to the material of the insulator, insulators can be divided into glass, ceramics and synthetic insulators. The insulators and metal fittings are connected by gluing, filling or crimping. However, in the natural Lightning weather is unavoidable under certain conditions. Therefore, in lightning weather, lightning will inevitably hit the insulator. Collecting parameters related to the thickness of the insulator struck by lightning has become a new research direction. [0003] Large-tonnage optical fiber composite insulators are long in length, generally about 10,000mm in length, and th...

AI Technical Summary

Problems solved by technology

[0003] Large-tonnage optical fiber composite insulators are long in length, generally about 10,000mm in length, and the diameter of the core rod is relatively thick. The existing method is to pre-embed the optical fiber in the pultrusion of the core rod. This process may cause damage to the optical fiber. It is difficult to guarantee the quality of UHV fiber composite insulators, and the work efficiency is low
