Abstract
The invention relates to a metal lead/optical fiber-mixed cable which is suitable for transmitting electric energy and optical signals, especially transmitting fire signals of cables, and can prevent the fire accident of cables through photoelectric control. The cable adds a single-mode fiber (2) to a metal cable of two, three or multiple cores, wherein the metal lead is a conductive material such as Cu, Al, Au or Ag in the prior art, the single-mode fiber is glass optical fiber or plastic optical fiber in the prior art, and the optical fiber is used for transmitting light signals and fire signals of cables.
Description
Technical field
The present invention relates to the cable of a kind of plain conductor and fiber mix, it is applicable to electric energy transmitting and light signal, and especially the transmission cable signal that catches fire can prevent cable fire to take place by photo-electric control.
Background technology
Existing cable technology though can select the insulation of fire proofing as cable for use, prevents that cable fire from taking place, and does not often reach its purpose in actual applications, and reason is ignition of cable arc discharge often, only depends on that cable material is fire-retardant not to have an effect.The fire disaster that ignition of cable takes place in reality production and life is of common occurrence, and especially ignition of cable causes gas, coal-dust explosion easily under the coal mine.
Summary of the invention
A kind of cable by plain conductor and fiber mix is provided, and this cable signal that can not only electric energy transmitting can also transmitting optical signal, especially transmission cable catches fire can be prevented ignition of cable by photo-electric control.
The scheme of technical solution problem of the present invention is: increase monomode fiber in two cores, three cores or multicore metallic cable, plain conductor is copper of the prior art, aluminium, gold, silver electric conducting material, monomode fiber is glass optical fiber of the prior art or plastic fiber, and the quantity of optical fiber can be one, two or many.Plain conductor is used for electric energy transmitting, and optical fiber is used for transmitting optical signal and ignition of cable signal.

Embodiment
The present invention is further described below in conjunction with accompanying drawing:
1. plain conductor; 2. optical fiber; 3. metal earth.
First kind of application scheme: when the cable breaking out of fire produces strong flame, the light that flame sends passes to power supply side by optical fiber 2, power supply side connects photelectric receiver (or photoelectricity receiving circuit) by plain conductor 1, amplification and control by photelectric receiver (or photoelectricity receiving circuit), make the outage of power supply power switch, stop the power supply of cable.
Second kind of application scheme: connect optoelectronic transceivers (or optoelectronic transceiver circuit) at power supply side by plain conductor 1, make two optical fiber 2 constitute the closed-loop path at the cable least significant end.During operate as normal, the light that photoemitter sends is through the closed-loop path of two optical fiber, turn back to photelectric receiver, mains switch does not disconnect, when the cable breaking out of fire produces strong flame, the high temperature of flame blows optical fiber, the photelectric receiver of power end does not receive light signal, does not perhaps receive the light signal of being launched, by the amplification and the control of photelectric receiver (or photoelectricity receiving circuit), make the outage of power supply power switch, stop the power supply of cable.
The invention is not restricted to the foregoing description; in design scope of the present invention; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection range of claim of the present invention.
Claims (1)
1. the cable of plain conductor and fiber mix, in two cores, three cores or multicore metallic cable, increase monomode fiber, it is characterized in that: plain conductor (1) is copper, aluminium, gold, silver electric conducting material, monomode fiber is glass optical fiber or plastic fiber, and optical fiber (2) quantity can be one, two or multifiber symmetric arrangement in plain conductor.
