OPPC on-line monitoring system for monitoring operating condition of power transmission line

The invention relates to an OPPC on-line monitoring system for monitoring the operating condition of a power transmission line. The OPPC on-line monitoring system comprises the power transmission line formed by a novel OPPC, a field monitoring device and a remote monitoring device, wherein tight tube optical fibers are arranged in a first optical unit of the novel OPPC, and loose tube optical fibers are arranged in a second optical unit of the novel OPPC; the field monitoring device comprises a monitoring module and a safety isolation module; one end of the line is connected to an optical fiber distribution frame through a splice closure and a guiding optical cable, and then is connected to the field monitoring device, and the other end of the line is connected to the optical fiber distribution frame through the splice closure and the guiding optical cable, and conducts fiber jumping loopback on the optical fiber distribution frame; the remote monitoring device comprises a monitoring management module, a data center module and a data analysis module. The OPPC on-line monitoring system for monitoring the operating condition of the power transmission line achieves real-time continuous monitoring of the temperature, the current-carrying capacity and the stress of the OPPC line in the whole process, provides powerful technical support for operation and overhauling of the line, and guarantees safe operation of a power grid.
