Live spanning system for spanning power line in pay-off construction and application method of live spanning system

Abstract

The invention discloses a live spanning system for spanning a power line in pay-off construction and an application method of the live spanning system. The live spanning system comprises temporary holding poles, bearing ropes, distance determining ropes, waving ropes, cameras and a plurality of three-dimensional spanning units, wherein each three-dimensional spanning unit comprises two ground wirespanning frames and three wire spanning frames; two ground wire spanning frames are arranged side by side; three wire spanning frames are centered and arranged at the lower parts of two correspondingground wire spanning frames side by side; adjacent wire spanning frames are connected through insulated fixed-length poles; adjacent ground wire spanning frames and wire spanning frames are connectedthrough insulated telescopic poles; adjacent three-dimensional spanning units are connected through the distance determining ropes to form a three-dimensional spanning network; the temporary holdingpoles are fixed on towers; two ends of the bearing ropes are fixed on the temporary holding poles for bearing the three-dimensional spanning network; the waving ropes are arranged at two sides of thethree-dimensional spanning network separately; and the cameras are arranged on the bearing ropes for real-time feedback.

Description

technical field [0001] The invention belongs to the field of line defense construction of power lines, and in particular relates to a live crossing system and an application method thereof for laying out construction across power lines. Background technique [0002] Crossing the power line mainly adopts construction schemes such as erecting spanning frames or sealing the network during temporary power outages. These methods require a large investment in manpower, materials, and tools, have low efficiency, poor economic benefits, and many risk factors. And with the improvement of power customers' requirements for power supply reliability and the importance of power safety to social and economic life, it is more difficult to apply for power outages, and the cost and safety risks are also greatly increased, especially for 220kV and 500kV and above grid main grids. If the power transmission lines are cut off for a long time, it will not only pose a threat to the stability of the...

[0002] Crossing the power line mainly adopts construction schemes such as erecting spanning frames or temporary power outages to seal the network. These methods require a large investment in manpower, materials and tools, low efficiency, poor economic benefits, and many risk factors

And with the improvement of power customers' requirements for power supply reliability and the importance of power safety to social and economic life, it is more difficult to apply for power outages, and the cost and safety risks are also greatly increased, especially for 220kV and 500kV and above grid main grids. If there is a long-term power outage, it will not only pose a threat to the stability of the power grid, but also cause various losses and impacts on industrial and agricultural production and national construction.

Therefore, the traditional blackout construction method has been increasingly unable to meet the needs of high-quality and reliable power supply
