A kind of de-icing device for electric wire based on crank rocker driving
Technical field
The invention belongs to electric wire deicing technical field more particularly to a kind of electric wire deicing dresses based on crank rocker driving
It sets.
Background technique
In China's most area, there is a large amount of snowfall every year, causes shape on the power transmission line of a large amount of ultra-high-tension power transmission line
At icing, these icing cause serious harm to the cable and shaft tower of ultra-high-tension power transmission line, and especially in recent years, high pressure is defeated
The icing of electric line causes cable fracture and shaft tower collapses, and causes the power failure of large area, and the safety for seriously threatening power grid is steady
Fixed operation, it is great that the life of economic construction and the people to China causes loss.Domestic powerline ice-covering is removed at present
Work also uses artificial de-icing method mostly, and the deicing by the way of manually being tapped with stick rod needs more personnel to put into this way
With resource input and required efficiency is not achieved, it is also difficult to ensure the life security of deicing personnel.Or use high-voltage line
The method of ice-melt, but high-voltage line ice-melt excessively expends energy, and apply the energy consumption of mechanical means deicing much smaller than big electricity
Flow ice-melt.Large current ice-melting method efficiency is higher, but costly, complicated for operation, has larger impact safely to system.
