Title:
INTELLIGENT MONITORING SYSTEM FOR VARIATION OF STRESS OF POWER TRANSMISSION LINE
Document Type and Number:
WIPO Patent Application WO/2015/161629
Kind Code:
A1
Abstract:
An intelligent monitoring system for variation of stress of a power transmission line. The intelligent monitoring system comprises a power transmission line. The power transmission line comprises: a plurality of conducting wire cores, the conducting wire cores being cladded in heat insulation linings, and magnesia insulation fillers being packed between the conducting wire cores and the heat insulation linings; and optical units, the optical units being accommodated in the magnesia insulation fillers. Each of the optical units comprises a plurality of optical fibres, wherein at least one of the optical fibres is a grating optical fibre on which a stress monitoring grating is inscribed; and grating stress monitoring points are formed on the grating optical fibre at intervals of a predetermined distance. A conductor made of pure copper with high electric conductivity has high electric conductivity; magnesia mineral is used as an insulation material, so that the insulating and fireproof properties thereof are good; and the variation in stress of a line can be monitored in real time.
