Abstract

The embodiment of the present application provides a monitoring method, device and system for DC icing operation of transmission lines, the method includes: measuring the thickness of icing on the transmission line; and activating the DC icing device according to the icing thickness being greater than the first threshold Melt the ice on the transmission line; measure the number of discharge photons on the surface of the insulator on the transmission line in real time; calculate the spot area on the surface of the insulator according to the number of discharge photons; The ice melting device stops melting ice. The system includes a monitoring center, a mobile terminal and a monitoring device for DC deicing operations on transmission lines. In the embodiment of the present application, the safety of the DC ice melting operation is ensured by monitoring the arc of the insulator on the transmission line, the number of discharge photons and the area of ​​the light spot.

Description

technical field [0001] The present application relates to the technical field of deicing operation of transmission lines, in particular to a monitoring method, device and system for direct current deicing operation of transmission lines. Background technique [0002] Transmission lines, especially ultra-high voltage and ultra-high voltage lines, play a vital role in the transmission of electric energy as the grid skeleton lines. The operation status of transmission lines is directly related to the quality of electric energy transmission. In rainy and snowy weather, icing will occur on the transmission line, which will cause damage to the tower, tripping of the line, tilting of the insulator string, sagging of the wire, etc., seriously threatening the safety and normal operation of the transmission line. [0003] When the transmission line freezes, deicing the transmission line is an important task for the ground staff. In the related technology, deicing the transmission lin...
