Abstract:
1. An apparatus for analysis of an electric power transmission link status comprising: a distributed temperature measuring unit installed along a longitudinal direction of an electric power transmission link directly buried or installed in a duct or a tunnel for obtaining a longitudinal distributed temperature from a distributed temperature sensor in real time; a conductor temperature calculating unit for calculating a conductor temperature of the electric power transmission link on the basis of the distributed temperature obtained by the distributed temperature measuring unit and an electric current flowing through the electric power transmission link; and an external thermal parameter calculating unit for calculating a heat flow emitted out of the electric power transmission link on the basis of the distributed temperature obtained by the distributed temperature measuring unit and the conductor temperature calculated by the conductor temperature calculating unit, and then calculating a thermal parameter of an external environment around the electric power transmission link in real time on the basis of the heat flow emitted out of the electric power transmission link.
