Electric power optical cable fiber fusion sleeve and manufacturing method thereof

Abstract

The invention provides an electric power optical cable fiber fusion sleeve, which solves the problem of interruption of optical fiber transmission due to optical fiber coating failure caused by heating combustion and deformation of the fiber fusion sleeve occurring in the operation process after optical fiber splicing in the strong electromagnetic field environment of power system substations, power transmission lines and power plants, and improves safety operation rate of an electric fiber backbone network. The electric power optical cable fiber fusion sleeve comprises a nonmetal non-magneticreinforced rib and an integrated protective tube coat. The protective tube coat comprises an optical fiber protection tube cavity and a rib placing cavity. The optical fiber protection tube cavity isa cavity, the two ends of which are opened. A welding fiber core is inserted into the optical fiber protection tube cavity and is then, welded in the optical fiber protection tube cavity. The rib placing cavity is arranged above the optical fiber protection tube cavity, and is a cavity, one end of which is closed and the other end of which has a rib placing port. The nonmetal non-magnetic reinforced rib is inserted into the rib placing cavity from the rib placing port, and then, is pressed and packaged in the rib placing port. The electric power optical cable fiber fusion sleeve is used for optical cable fiber splicing in the strong electromagnetic field environment of ultra-high-voltage, super-high-voltage and high-voltage substations, power transmission lines, power plants and industrial chemical, ship and medical industry equipment. The invention also provides a manufacturing method thereof.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to a power optical cable fusion fiber sleeve and a manufacturing method thereof, which are mainly used in ultra-high voltage, ultra-high voltage, and high-voltage substations, power transmission lines, power plants, and equipment in industrial chemicals, ships, and medical industries Fiber optic cable splicing in strong electromagnetic field environment. Background technique [0002] At present, OPGW, OPPC, OPLC, ADSS, AD-LASH, and GWWOP optical cables are used in UHV, EHV, and HV substations and transmission lines in domestic and foreign power systems. Because these optical cables are operated in substations and high electromagnetic field environments in transmission lines, the fiber cores in the splicing box are often fused, and the fiber cores and sheaths at the fiber sleeves are burned, causing fiber channel transmission to be interrupted, resulting in grid automat...
