Abstract
The utility model relates to an optical fiber temperature detection defect early warning composite power cable. A temperature measurement optical fiber is arranged between the inner of a cable core or a metal shielding layer of the cable core and an isolating layer outside of the cable core. The power cable can correctly measure the temperature rise case of the online power cable, detecting the point continuance and displaying the temperature value. The optical fiber temperature detection defect early warning composite power cable can has realization of the accident precaution, high dependability, convenient maintenance and lower expense.
Description
Affiliated technical field
The utility model relates to a kind of power cable, especially has the power cable of optical fiber temperature-measurement function.
Background technology
When existing power cable carries out temperature measurement on-line, generally adopt temperature sensing cable thermometric and thermistor temperature detecting.
The temperature sensing cable thermometric is temperature sensing cable and power cable parallelization, and when the power cable temperature surpassed setting, temperature sensing cable was by short circuit, thereby the power cable operating position is monitored, but can not carry out the initial failure prediction, also do not have the temperature trend analysis.
Thermistor temperature detecting adopts the point temperature sensor thermometric, needs at each cable surface point for measuring temperature a transducer to be installed, and for the application of large tracts of land, long distance, quantities is big, expense is high, and the cloth dot density is restricted and can't measures temperature between points.
Summary of the invention
In order to overcome the deficiency that the online temperature survey of existing power cable exists, the utility model provides a kind of new power cable, temperature rise situation that can the online power cable of correct measurement, test point is continuous, and energy displays temperature value, realizes fault pre-alarming, the reliability height, easy to maintenance, expense is lower.
Optical fiber temperature-measurement fault pre-alarming composite power cable provided by the utility model comprises cable core (8) and oversheath (12), cable core (8) contains conductor (1) and reaches screen (2), insulating barrier (3), insulation screen (4), the metal screen layer (5) of coating conductor (1) successively, between cable core (8) and oversheath (12), be provided with separator (9), in power cable, also be provided with thermometric optical fiber (6) and sleeve pipe (7) thereof
According to different instructions for uses, thermometric optical fiber of the present utility model (6) and sleeve pipe (7) thereof can adopt three kinds of scheme settings: one is arranged on cable core (8) central authorities, two are arranged on cable core (8) edge, and three are arranged between the metal screen layer (5) and the separator (9) outside the cable core (8) of cable core (8).
When thermometric optical fiber (6) and sleeve pipe (7) thereof are arranged on cable core (8) central authorities or edge, can also set gradually sheath (10) and armour (11) between separator of the present utility model (9) and the oversheath (12).
When using, the utility model only needs optical fiber (6) is linked to each other with the monitoring equipment of power cable terminal, at any time the temperature rise situation of monitoring power cable.
The beneficial effects of the utility model be can the online power cable of correct measurement the temperature rise situation, test point is continuous, and can the displays temperature value, realizes fault pre-alarming, the reliability height, easy to maintenance, expense is lower.
