In this paper

the mechanism of icing on overhead ground wire is studied

and the mechanical calculation shows that under the same conditions

the overhead ground wire is easy to break

which can lead to the collapse of the tower. In order to avoid the influence of the icing breakage of the overhead ground wire on the reliable operation of the transmission line

this paper based on the principle of the wind cup directional rotation

designs a kind of anti-icing device of overhead ground wire passive mechanical type

calculates the friction force and traction device of overhead ground wire through using certain meteorological conditions

it can provide the initial wind power cycle walk into the device

through the optimization design of the mechanical structure of the device

making it in the overhead wire repeatedly walk effectively cleaning ground rime and glaze initial

achieve anti-icing function;and the device has the advantages of small volume

simple to install and use

without power supply

mechanical drive

use suitable for bad weather conditions

it is proved that the device has very strong practicability.
