Abstract
The utility model relates to an electric cable with temperature monitoring function, comprising an insulating outer jacket layer(5) and a cable core(1) which is sleeved in the insulating outer jacket layer. The utility model is characterized in that a temperature measuring optical fiber unit(6) is arranged between the insulating outer jacket layer(5) and the cable core(1) along the direction of the cable length. The cable of the utility model can continuously monitor temperature change in the operation process of the cable through the temperature measuring optical fiber unit built in the cable; can not only timely grasp the capacity of the cable, but also monitor the partial warming up problem of the cable to judge whether the part has defect so as to take corresponding measures in time.
Description
(1) technical field
The utility model relates to cable temperature measurement on-line technical field, particularly a kind of cable with temperature monitoring function.
(2) background technology
In the whole service process of cable, the working temperature of the ampacity of cable (A) and cable has direct relation, and the safety that the working temperature of cable directly has influence on whole electric power system whether.For a long time, the scientific worker is seeking a kind ofly can carry out continuous monitoring monitoring technology scheme to the temperature of cable by certain comparatively simple technological means always, be used in time grasping the ampacity size of cable, and the issuable local heating of cable problem monitored, judge whether this part exists defective, so that in time take Corresponding Countermeasures.
(3) summary of the invention
The purpose of this utility model provide at the problem that need to solve in the above-mentioned prior art just a kind of can be in the whole service process of cable by the temperature measuring unit of inserting in the cable at any time to the ampacity size of whole cable, the cable that local heating's problem monitors with temperature monitoring function.
The purpose of this utility model can realize by following measure:
Cable with temperature monitoring function of the present utility model comprises the insulation external sheath layer and is wrapped in the cable core of insulation in the external sheath layer, between the insulation external sheath layer and cable core of cable, be provided with the thermometric fiber unit along the cable length direction.
Cable described in the utility model can be multicore cable, also can be single-core cable; For multicore cable, described thermometric fiber unit can place the cable core intermediate gap of multicore cable; Also can place the slit, the cable core outside of multicore cable; Described thermometric fiber unit can be set in place in cable core and insulation in the metal screen layer between the external sheath layer for single-core cable.
Cable of the present utility model can carry out the continuous monitoring monitoring to its variations in temperature by the thermometric fiber unit that its inside is inserted in the whole service process of cable, not only can in time grasp the ampacity size of cable, also can local heating's problem of cable be monitored simultaneously, judge whether this part exists defective, so that in time take Corresponding Countermeasures.
