Background technology
The low temperature sleet and snow ice extreme weather disaster continued can cause serious baneful influence to electric power netting safe running, the serious icing of such as power transformating and supplying facility, and transmission line falls tower, broken string, tripping operation, some areas large-area power-cuts etc.According to incompletely statistics, in 2008, because low temperature sleet and snow ice extreme weather disaster, China Power Grids system has 15486 secondary lines and stops transport, and has 8709 (bases) 110 volts of Above Transmission Lines and falls tower, have 1563 transformer stations and stop transport.Even there are the serious problems such as whole city power failure in part districts and cities, What is more, have also appeared casualties.
The icing of overhead transmission line refers in early winter and time in the early spring (temperature is at about-5 DEG C), or in snowfall or the weather that snows with a mingling of rain, at the bent ice sheet that the place such as wire, lightning conducter, insulator string of overhead transmission line is mixed to form by ice, frost and snow slush.This is the solid and transparent or semitransparent closely ice sheet of one deck, and be the reason forming hat ice sheet, its Crack cause is, the water droplet that nature object adheres to is when mercury dropped, and these water droplets just congeal into ice, and tie thicker and thicker.
When built on stilts electric line ice and snow is too much, when serious icing appears in line conductor, lightning conducter, is first the mechanical load increasing the weight of wire and shaft tower, conducting wire sag is too increased, thus cause swinging cross or broken string; When coating ice falling on wire, lightning conducter, wire, lightning conducter generation chattering can be made again, thus cause swinging cross accident.In addition, too much owing to porcelain vase or cross-arm gathering ice and snow, also can cause the flashover fault of insulator.
Regulation loading during designed lines can be exceeded when the icing of wire and lightning conducter is serious.If also attend by high wind when wire, lightning conducter generation icing, its loading more will increase, and this may cause wire or lightning conducter broken string, gold utensil and insulator string is destroyed, even makes shaft tower damage.Especially fan-shaped icing, it can make wire twist, so threaten maximum to gold utensil and insulator string.
Given this, industry develops multiple de-icing method:

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.
