Description

Technical Field

[0001] The invention relates to a transmission tower safety device in the technical field of flashover protection, in particular to a structural device for preventing transmission tower jumper flashover. Background Art

[0002] With the rapid development of power systems, overhead transmission lines have been built and covered on a large scale. However, this has also brought with it safety risks in line operation. Long-distance transmission lines are susceptible to lateral wind loads. Due to the low inherent weight of transmission lines, they are prone to swinging when subjected to strong winds, which can easily reduce the distance between the live conductors and the towers. When this distance is too small, flashover can occur. Flashover refers to the phenomenon of discharge along the surface of a solid insulator when the gas or liquid dielectric surrounding it breaks down. Sparks or arcs in the flashover channel cause local overheating of the insulation surface, resulting in carbonization and damage to the surface insulation, which can easily lead to unstable power transmission and wind-induced tripping.

[0003] In order to avoid flashover in transmission lines, the main method is to install insulating protective sleeves on the conductors and use cable devices to prevent the high-voltage wires from deviating toward the tower. However, these two methods also have disadvantages, such as low success rate of anti-flashover and poor stability, so it is necessary to improve them. Summary of the Invention
