Abstract
The utility model provides a cable with a fiber which relates to an electric power wire field, in particular to a cable provided inside with the fiber. The cable is provided with one or more than one length of fiber in an electric power cable which is combined with the fiber to realize the long distance monitoring to the cable online. The utility model which is simple in structure and facilitates the online detection of the electric power, brings with a novel use of the cable, realize the online monitoring to the conductor temperature and the stress condition of the cable through arranging relative equipment and is a combination of the electric power cable and the fiber.
Description
The cable of technical field the utility model band optical fiber belongs to the power cable field, particularly relates to a kind of cable that is provided with optical fiber in cable.
The background technology power cable is in operation and all will be defined under certain ambient temperature, allow the electric current of power cable by limit, guarantee the useful life and the safety of the insulating barrier of power cable, the measurement of power cable conductor working temperature is to infer by the temperature of measuring cable surface, it is big to measure difficulty for the cable that buries ground, the characteristics of optical fiber transmission signal are that attenuation constant is little, repeater span is long, utilize optical fiber to have the characteristics of back-reflection transmission principle to obtain the information such as temperature of optical fiber place space-time, form online long distance detection the transmission signals of light.
The cable that provides a kind of power cable to combine with optical fiber is provided the purpose of this utility model, can effectively realize the online long distance detection to cable.
The content the purpose of this utility model of utility model reaches by following measure, and it is the optical fiber that is provided with in power cable more than one or, and power cable combines with optical fiber, realizes the online long distance detection to cable.By disposing relevant equipment, realize the conductor temperature and the force-bearing situation of online monitoring cable.
Power cable of the present utility model is by conductor, and insulating barrier and oversheath are formed, and optical fiber can be arranged between insulating barrier and the oversheath.The variations in temperature of conductor is by the online long distance detection of optical fiber.Cable also can be armouring or have metallic sheath that for various dissimilar cables, the utility model can be realized.
Optical fiber of the present utility model can be arranged in the conductor of cable, optical fiber and conductor stranded formation cable core, outsourcing insulation and oversheath.
For multicore cable, optical fiber can be arranged between the cable core, and the variations in temperature of cable core conductor is by the online long distance detection of optical fiber.
For the single-core cable of many conductors, optical fiber can be arranged between the conductor, and the variations in temperature of conductor is by the online long distance detection of optical fiber.
The utility model is simple in structure, makes things convenient for the online detection of power cable, has opened up the new purposes of cable, by disposing relevant equipment, realizes the conductor temperature and the force-bearing situation of online monitoring cable, is the cable that a kind of power cable combines with optical fiber.
