Embodiment

[0013] As shown in the figure, the transmission line icing monitoring system includes the monitoring system and the remote icing monitoring device. The monitored point realizes the collection function of the ice thickness sensing signal.

[0014] The remote ice monitoring device is a fiber Bragg grating sensor network, the sensor network is composed of 4 sensor channels, and each channel is composed of a plurality of FBG sensing units. Each FBG sensing unit represents an ice-covering monitoring device, and multiple ice-covering monitoring devices can be connected in series to each channel, and four channels can form an ice-covering monitoring sensor network. Each or a plurality of icing monitoring devices may be installed at a position close to the ground wire of the power transmission tower.

[0015] The monitoring system includes a FBG sensor demodulator, a data processing module and a display system module. The optical signal is sent by the broadband light source of the F...

Abstract

The invention relates to a power transmission line icing monitoring system comprising a monitoring system and a far-end icing monitoring device. The monitoring system is arranged in a monitoring center and realizes demodulation, display and alarm of sensing signals. The far-end icing monitoring device is arranged at a monitored point and realizes the acquisition function of icing thickness sensing signals. Icing thickness real-time monitoring is realized so that the power transmission line icing monitoring efficiency is high and the re-patrolling period is short.

Description

technical field [0001] The invention relates to an icing monitoring system for transmission lines. Background technique [0002] Affected by the macro-climate, micro-topography, and micro-meteorological conditions in my country, ice disaster accidents occur frequently, and the overhead lines are seriously affected by the reliability of transmission lines due to snow accumulation. Early ice and snow observations on transmission lines mainly relied on ice observation stations and manual inspections, which had disadvantages such as low efficiency and long re-inspection cycles. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a transmission line icing monitoring system, which solves the problems in the prior art of low efficiency of transmission line icing monitoring and long re-tour cycle. [0004] Technical scheme of the present invention is as follows: [0005] Transmission line icing monit...
