Transmitting and sensing optical cable

Abstract

The invention relates to a transmitting and sensing optical cable which can transmit 0.2KV-1500KV high-voltage heavy-current electricity and optical signals and real-time on-line monitor the operation status of lines and the status of ambience thereof. The transmitting and sensing optical cable has two forms, one form of the transmitting and sensing optical cable is formed by wringing a metal conductive core, an optical fiber or fiber bundle for transmitting the optical signals, a reinforcer and a sensing optical fiber or fiber bundle for real-time on-line monitoring the operation status of the lines and the status of ambience thereof; and the other form of the transmitting and sensing optical cable is formed by winging the optical fiber or fiber bundle for transmitting optical information, the sensing optical fiber or fiber bundle for real-time on-line monitoring the operation status of the lines and the status of ambience thereof and the metal conductive core. The transmitting and sensing optical fiber or optical wire is coated with three layers: a sheathing layer, an insulating layer and a flame-retardant layer. The sensing optical fiber or fiber bundle is a non-linear fiber or fiber bundle; and the optical fiber or fiber bundle for transmitting the optical signals is a single mode fiber or multimode fiber. The optical cable is characterized in that: the cable can real-time on-line monitor the operation status of the lines and the status of ambience thereof, and is convenient for remote monitoring management and real-time maintenance in dealing with natural disasters such as fire, snow and the like as well as other environmental factors.

Description

technical field [0001] The present invention relates to optical and electrical transmission media, that is, optical cables or optical cables for transmitting high voltage, large current and optical information at the same time, on the same path, in the same direction, and on the same cable. Background technique [0002] In the power system, power cables with different voltage levels are used to transmit or distribute high-voltage and high-power electric energy. Compared with the overhead bare wire, the power cable has less interference from the external climate environment and high power supply reliability; the larger capacitance is conducive to improving the power factor of the power system; it has an insulating layer, a sheath, and an outer sheath, which can withstand mechanical It has the advantages of external force or pulling force, safety, and not easy to be damaged, but it can only transmit electric energy. As an optical signal transmission medium, the optical cable ...
