Abstract
This invention relates to a cable mixed by metal leads and fibers suitable for transmitting electric energy and optical signals, especially transmitting fire signals of cables, which adds single-mode fibers in a metal cable of two, three or multiple cores, in which, the mnetal lead is Cu, Al, Au or Ag conductive material used in transmitting electric energy, and the single-mode fiber is glass fiber or plastic fiber, and the number of fibers can be one, two or many used in transmitting optical signals and cable fire signals.
Description
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.
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.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of cable by plain conductor and fiber mix is provided, 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.
Because the present invention adopted such scheme, thereby make it can also transmitting optical signal in electric energy transmitting, its light signal be not only common control signal, goes back the transmission cable signal that catches fire.
For the ease of understanding structure of the present invention and implementing best mode of the present invention, the present invention is further described below in conjunction with accompanying drawing.

In Fig. 1: 1. plain conductor; 2. optical fiber; 3. metal earth.
Three optical fiber 2 of symmetric arrangement between the three core metal leads 1 in Fig. 1 are at the ground wire 3 of the center of three core metal leads 1 layout metal material.
In Fig. 2: 1. plain conductor; 2. optical fiber; 3. metal earth.
An optical fiber 2 is arranged in three core metal leads, 1 center in Fig. 2, at the ground wire 3 of other location arrangements metal material of three core metal leads 1.
In Fig. 3: 1. plain conductor; 2. optical fiber.
Two optical fiber 2 of symmetric arrangement between the two core metal leads 1 in Fig. 3.
In Fig. 4: 1. plain conductor; 2. optical fiber.
Arrange an optical fiber 2 between the two core metal leads 1 in Fig. 4.
For four above optical fiber, optical fiber is any symmetric arrangement between plain conductor.
Action principle of the present invention is as follows:
First kind of application scheme: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, when the cable breaking out of fire produces strong flame, the light that flame sends passes to the photelectric receiver (or photoelectricity receiving circuit) of power supply side by optical fiber 2, 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: as Fig. 1, Fig. 2, shown in Figure 3, be provided with optoelectronic transceivers (or optoelectronic transceiver circuit), make two optical fiber constitute the closed-loop path at the cable least significant end at power supply side.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.
