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
The present invention relates to light, electrical transmission media, simultaneously promptly, go the same way, with trend, with the optical cable or the photoelectricity line of cable transmission high voltage, big electric current and optical information.
Background technology
In electric system, transmission or distribution high voltage, high-power electric energy will use the power cable of different electric pressures.Power cable is compared with aerial bare line, have be subjected to extraneous climatic environment disturb little, power supply reliability is high; Electric capacity is bigger, helps improving the power factor of electric system; Insulation course and sheath are arranged, and outer jacket, can bear acting forces such as mechanical external force or pulling force, safety is difficult for advantages such as impaired, but only can electric energy transmitting.And,, must make baroque optical cable in order to guarantee to use with various environment are medium-term and long-term under various conditions as the optical cable of optical signal transmission medium.In society now, usually need simultaneously, go the same way, with moving towards electric energy transmitting and light signal, satisfying the needs of power and information transmission and measurement, thereby need power cable laying and optical cable respectively, this has just increased the construction investment of engineering difficulty greatly.For this reason, the inventor has invented can be simultaneously, go the same way, with trend, with the photoelectricity line or the optical cable of cable transmission high voltage, big electric current and optical information, and declared Chinese patent and international monopoly.But this optical cable or photoelectricity line also do not possess the function of energy real time on-line monitoring circuit running status and ambient conditions, can not tackle the variation of faults itself and surrounding environment.Influence its result of use.
Summary of the invention
The present invention a kind ofly can be transmitted 0.2 kilovolt ~ 1500 kilovolts high voltages, large-current electric energy and light signals, again can real time on-line monitoring circuit running status and the transmitting and sensing optical cable of its ambient conditions, it has two kinds of forms: one is for by the metallic conduction core with transmit the optical fiber of light signal or fibre bundle and reinforcement and can real time on-line monitoring circuit self-operating state and the sensor fibre or the fibre bundle twisting all-in-one-piece transmitting and sensing optical cable of its ambient conditions; Its two be by the optical fiber that transmits optical information or fibre bundle with can real time on-line monitoring circuit self and the sensor fibre of ambient condition or fibre bundle and metallic conduction core twisted together, cover the transmitting and sensing optical cable or the photoelectricity line of restrictive coating, insulation course and fireprotection layer outward.Its sensor fibre or fibre bundle are a kind of nonlinear optical fiber or fibre bundle, have nonmetal or the metal beam tube outside it.The optical fiber or the fibre bundle that transmit light signal are single mode or multimode optical fiber, and metal or nonmetal beam tube are arranged outside it.The optical fiber of sensor fibre or fibre bundle and transmission light signal or fibre bundle also can be with placing in same metal or the nonmetal beam tube, and the optical fiber of transmission optical information or fibre bundle and sensor fibre or fibre bundle can place any one deck of transmitting and sensing optical cable.The metallic conduction core can be solid conductor or phase line or triple-phase line and zero line, ground wire.There are the markings that obviously are different from its true qualities on transmitting and sensing optical cable restrictive coating surface.Transmitting and sensing optical cable, when the photoelectricity line is bare wire, the surface scribbles the sign line segment different with the wire surface color.Fireprotection layer is low smoke halogen-free flame-retardant polyolefin or asbestos material.
Transmitting and sensing optical cable of the present invention can transmit 0.2 kilovolt ~ 1500 kilovolts high voltages, large-current electric energy and light signals, again can real time on-line monitoring circuit running status and its ambient conditions, disaster and other environmental factors such as fire, ice and snow be can tackle, remote monitoring management and real-time servicing are convenient to.
