Description

Lightning protection system for transmission tower and its installation method { Lightning protection system for transmission tower and its installation method }

The present invention relates to a lightning protection system for a transmission tower in the field of transmission technology and a method for installing the same, and more particularly, a lightning rod and a conductor can be installed in a sufficiently insulated state with respect to the transmission tower, and a discharge path from the lightning rod to the ground wire. Ensure that the entire insulation state with the transmission tower is sufficiently maintained so that lightning does not flow along the transmission tower to prevent lightning accidents to pedestrians or workers around the transmission tower. It relates to a lightning protection system of a transmission tower to buffer and an installation method thereof.

In general, lightning is a phenomenon in which tremendous electric energy generated by being charged like static electricity by the active flow of air is discharged to the ground surface.

In order to prevent various damages caused by lightning, transmission towers, transmission and reception towers for broadcasting and communication, power generation or transformer equipment, military bases (laser bases), high-rise buildings, and high-rise apartments are equipped with various lightning rods to discharge currents such as lightning strikes into the ground. installed

A conventional lightning protection device installed on a transmission tower installs an overhead branch wire on top of the transmission tower so that lightning disappears through a ground wire buried in the ground without affecting the transmission overhead wire when lightning strikes the transmission tower. .

However, if a lightning strike occurs around the transmission pylon, even though the lightning is extinguished (discharged) through the transmission pylon and the earth ground wire and does not affect the overhead power transmission line, it is also affected by the steel structure of the transmission pylon that is wet or flowing down. Lightning strikes directly. Due to this, there is a problem in that a pedestrian or worker passing around the transmission tower at the moment when lightning occurs is seriously injured due to a lightning accident.

The foregoing invention refers to the background art in the technical field to which the present invention belongs, and does not mean the prior art.
