Optical phase conductor (OPPC)

Abstract

The invention relates to the technical field of power communication and particularly relates to an optical phase conductor (OPPC). The optical phase conductor is used for the updating reconstruction engineering of a 10kV rural power line so as to finish the construction of a communication channel required by a matched system for power utilization information acquisition and failure indication. The exterior of an optical fiber unit is wrapped by a hard-drawn aluminum wire, and a conductor shielding layer and an insulating layer are sequentially arranged outside the hard-drawn aluminum wire. The optical phase conductor has the advantages that power transmission and optical fiber communication can be combined; resources are saved; when the OPPC is used for the updating reconstruction of an original line, the original line is free from a hidden danger caused by the addition of an extra load; the corrosion resistance is high, and the service life is long; the thermostability is great; the hidden accident dangers such as lightning stroke strand breakage and overheat short-circuit current cannot occur; and an extra load cannot be added to a line pole tower. Besides, through the utilization of the power transmission line, the construction of the communication channel required by the system for power utilization information acquisition and failure indication is finished, and the intelligent reconstruction of a rural power grid can be finished.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to an optical fiber composite overhead phase line (OPPC). It is used in the 10kV agricultural power line-Huishan line upgrading and reconstruction project in Shenbei area, Liaoning Province, to complete the construction of the communication channel required for the supporting power consumption information collection and fault indication system. Background technique [0002] At present, the commonly used overhead optical cables in China include OPGW and ADSS. The commonly used structure of OPGW is all-aluminum clad steel layer stranding or aluminum clad steel and aluminum alloy mixed stranding structure; ADSS is generally a layer stranding type in which aramid yarn is evenly wound outside the cable core covered with inner cushion, and then covered with black polyolefin sheath Or central tube structure. The disadvantages and shortcomings are that OPGW is prone t...

Problems solved by technology

The disadvantages and deficiencies are that OPGW is prone to potential accidents such as lightning strikes, broken strands, and short-circuit current overheating, while ADSS is prone to electrical corrosion, which will cause damage to the optical cable or cable breakage.
