Power line conductor insulation protection device with monitoring feedback function

Abstract

The invention discloses a power line conductor insulation protection device with a monitoring feedback function. The device comprises a cable core, a first end cover and a second end cover. An inner protective layer is fixed outside the cable core. An armor layer wraps the inner protective layer. An insulating layer is arranged outside the armor layer. Optical fibers are arranged inside the insulating layer. Fixing sleeves are respectively fixed at the two ends of the armor layer. The first end cover is arranged at one end of the insulating layer. The first end cover is connected with a lightguide tube. The other end of the light guide tube is connected to a laser exit port of a laser beam splitter. The laser beam splitter is provided with a laser entrance port. The second end cover is arranged at the other end of the insulating layer. A laser sensor is mounted on the second end cover. The power line is monitored by detecting the optical fibers in the optical fibers. The power line conductor insulation protection device has the advantages of high stability of the optical fibers, low failure rate, stable laser signal transmission, long monitoring distance and high precision.

Description

technical field [0001] The invention belongs to the technical field of electric power monitoring devices, and in particular relates to a power line wire insulation protection device with a monitoring and feedback function. Background technique [0002] Power lines are mainly divided into transmission lines and distribution lines. The transmission line generally has a higher voltage level, a stronger magnetic field, and a longer distance to penetrate the air (arc). 35kV, 110kV, 220kV, 330kV (in a few areas), 660kV (in a few areas), DC / AC500kV, DC800kV and the new Shanghai 100kV are all transmission lines. It is the electricity generated by the power plant after being boosted by the step-up station, then sent to each substation, and then all substations are connected in series and parallel to form a transmission line network, which connects the "line" between each node on this "network" It's the transmission line. [0003] In order to ensure the safety of power lines, it is...

Problems solved by technology

[0003] In order to ensure the safety of power lines, it is necessary to monitor the power lines. The existing monitoring methods usually use wireless video monitoring. The range of wireless video monitoring is small, and it is difficult to monitor long-distance transmission lines, and the monitoring equipment is exposed to the external environment. Medium, the failure rate is high, it is difficult to ensure the normal monitoring status for a long time, and the monitoring efficiency is low
