By the ground network that had better not use power plant and electric substation during short circuit current ice melting, and adopt independent earthing device, to avoid danger.During with short road electricity stream Rong ice, circuit of also should sending someone goes the fusion process of observing icing, when icing has started to come off from wire, ice melting current should be cut off immediately, otherwise the time one is long, wire can be made overheated, should note the junction of wire especially.Visible, under general appointed condition, electric current melting ice method is difficult to realize, and therefore, except except heavy icing area, its practical value is little.

2, mechanical deicing's method.

Mechanical deicing mainly adopts following several way:

One, from guiding line ground or the short waddy of lightning conducter throwing, smash icing, make it to come off.Also can carry out putting to grab making coating ice falling with rod or bamboo pole.If line outage difficulty also can beat icing with insulating bar.

Two, be enclosed within wire with wooden lasso, and draw along wire with rope, just can eliminate icing.

Three, deicing is carried out with pulley type ice removal.

In a word, the mechanical deicing of ultra-high-tension power transmission line must climb up on steel tower and wire and could implement, the personal safety of serious threat electric power worker by electrical employee.In addition, the major defect of mechanical deicing's method must have a power failure in addition and carry out, time-consuming, effort, and is not easy to ensure that any damage does not occur for wire and lightning conducter.
