Abstract
The invention discloses an intelligent temperature measuring soft cable with 6/10kV rated voltage for a coal mine. The cable comprises three groups of copper core tin plated soft conductor cable cores, an inner twisted optical fiber, a surface-mount optical fiber and three outer protection layers, the three groups of copper core tin plated soft conductor cable cores are twisted together and wrapped by the three outer protection layers, the outermost layer is a chloroprene rubber sheath layer, the inner twisted optical fiber is mounted at the central hollow position after the three groups of copper core tin plated soft conductor cable cores are twisted together, and the surface-mount optical fiber is mounted in the chloroprene rubber sheath layer. Distributed optical fibers are added into the cable, distribution of temperature fields at temperature measuring optical fibers in the cable is measured by the aid of distributed optical fiber temperature sensing technology, change of the temperature along different positions of the optical fibers is detected according to the temperature effect of optical time domain reflection and back Raman scattering of the optical fibers, and really distributed measurement is realized.
