Description
Technical field
The present invention relates to overhead transmission line deicing device technical field, more particularly to a kind of flexibly ground wire deicing wiring dress
Put.
Background technology
In overhead transmission line, China's winter easily occur under some high and cold mountain areas or exceedingly odious weather conditions icing compared with
The situation of weight.Uneven icing is also easy to produce unbalanced tension force, causes wire strand breakage broken string, the damage of shaft tower loose or dislocation, tower material very
To major accidents such as towers.Further, since on steel tower aerial earth wire unlike transmission pressure can by load current caused by heat energy
Part frost is resisted, therefore, ground wire ice covering thickness is typically considerably beyond transmission pressure.
At present, domestic existing ground wire deicing automatic connection device can ask in the ground wire icing that preferably solves lower to a certain degree
Topic, but the device build is larger, it is necessary in advance on an iron rake with three to six teeth, and it can only melt equipped with ground wire deicing automatic connection device
Icing in Ji Ta sections, the icing outside ground wire deicing automatic connection device section can not be melted, and after ground wire deicing, may be used also
The phenomenon that local icing does not melt can occur.Simultaneously as icing is serious in regional area, putting under the conditions of easy breakdown icing
Electric gap, cause tripping operation, lead to not ice-melt.
The content of the invention
