Description

Deicing device for power transmission line

Technical Field

The utility model relates to the technical field of power transmission line maintenance equipment, in particular to a power transmission line deicing device.

Background

It is well known that ac/dc power transmission lines are one of the largest natural disasters of power systems during winter ice coating. The cold drops fall onto objects with a temperature below the freezing point, forming rime. If the ice is condensed on the power transmission line, the power transmission line ice coating is formed, and for high-voltage power transmission lines with long-distance power transmission, the load of the iron tower is increased by supporting the ice coating through the iron tower, and the heavy ice coating can enable the iron tower to collapse due to the fact that the iron tower is powerless to support the power transmission lines. And when the insulator string on the iron tower is covered with ice, the transmission line can only be pulled out to stop transmission of electricity, so that large-area power interruption is caused.

At present, in order to solve the icing problem of a power transmission line, a deicing device is generally adopted to clean the icing on the power transmission line, and when the existing power transmission line deicing device is used, the structure of the existing power transmission line deicing device is complex, the installation efficiency is low, and therefore the deicing efficiency of the power transmission line is low.
