Fiber core connection method and structure for sharing large-core-number OPGW

Abstract

The invention relates to a fiber core connection method and structure for sharing a large-core-number OPGW. The structure comprises a direct-melting type OPGW connecting box and a plug-in type OPGW connecting box which are detachably connected together. An OPGW welding unit is installed in the direct-melting type OPGW connecting box, an OPGW inserting unit is installed in the plug-in type OPGW connecting box, a fiber core of a large-core-number OPGW on a connecting point of an electric power tower carrying emerging service communication equipment is divided into two parts, a part of the fiber core adopts a direct welding mode and is connected in a segmented mode to form a long-distance main OPGW transmission long channel, and the other part of the fiber core adopts a plug-pull type connection mode to form a sectional type interval optical fiber transmission short channel. According to special requirements of emerging services, the flexible use of interval OPGW communication can be met, the utilization rate of the large-core-number OPGW is greatly improved, the practicability is high, and huge economic and social benefits are generated.

Description

technical field [0001] The invention relates to a fiber core splicing method and structure for sharing a large core number OPGW. Background technique [0002] For a long time, the traditional OPGW has been mainly responsible for the transmission of real-time information on power grid operation such as power system relay protection and dispatch automation, as well as communication business information such as power supply marketing, administrative command management, and information communication. [0003] With the advancement of the strategic goal of "building an internationally leading energy Internet with Chinese characteristics", with a strong smart grid as the basic platform, strengthening network interconnection and advanced information, communication, and control technologies continue to be promoted and applied, in the field of intelligent operation and maintenance of high-voltage transmission lines The OPGW optical fiber communication channel transmits the monitoring ...

Problems solved by technology

However, the connection point location setting method and optical fiber connection method of the existing transmission line OPGW are difficult to meet the needs of optical fiber communication for applications such as the transmission tower mount communication 5G base station, the Internet of Things, online monitoring of the operation status of power transmission lines, and auxiliary video surveillance. It will seriously restrict the actual application effect of large-core OPGW, resulting in a waste of investment in large-core OPGW. At the same time, it will greatly increase the cost of emerging business projects such as 5G shared iron towers, power Internet of Things, and online monitoring of transmission lines, which will restrict the development of emerging businesses and fail to achieve expectations. economic and social benefits
