Description
Technical field
It the utility model is related to power supply technique field, more particularly to a kind of anti-icing transformation device of anti-icing transmission line of electricity.
Background technology
The normal operation of modern society be unable to do without the regular supply of electric power.In the winter time, since temperature is low, in sleet etc.
Under weather condition, icing phenomenon easily occurs on transmission line of electricity.Transmission line of electricity, especially ultra-high-tension power transmission line, power supply distance length,
The capacity of transmission of electricity is big, once breaking down, it will the electricity consumption entity and individual to downstream cause the huge economic loss of total amount.Such as
There occurs the accident of tower and broken string, use of this accident to downstream for the 500KV extra high voltage networks of Central China Power Grid in 2005
Economic loss caused by electric unit has exceeded 10,000,000 yuan.Through looking into, the main reason for this accident is exactly the icing of transmission line of electricity
Thickness exceedes caused by the ice covering thickness that design allows.Certainly, except this extreme case of the broken string of falling tower, powerline ice-covering
Harm is also possible to show overload, uneven icing or the same period does not deice, ice coating wire is waved, insulator rupture etc..
In modern industrial production, many large electricity consumers such as electrolysis aluminum production enterprises, according to the scale of production, a blowing out
Accident will cause few then million, at most 10,000,000 economic loss.Therefore, it is modern society that transmission line of electricity, which stablizes supply electric power,
The fundamental importance that can be run well, Anti-icing of Transmission Lines become a research topic with extremely strong realistic meaning.
At present, the research direction of international and national, is gathered on clearing ice technology, is roughly divided into following several classes：
1st, natural external force deicing.This is clearing ice technology most simple and practicable and most ripe at present.The technology mainly utilizes
The natural external forces such as strong wind and difference variation in nature remove powerline ice-covering；This is most simple and practicable and most ripe at present
Clearing ice technology.
2nd, mechanical deicing.Mechanical deicing is that icing is directly rooted out by machinery, mainly includes electromagnetic pulse deicing, slides
Shovel scrapes three kinds of modes of deicing and artificial deicing.These de-icing methods are more ripe, but removing rate is low, affected by environment big.Electromagnetism
The repulsion that pulse de-icer makes full use of the magnetic field of vortex to be produced with coil magnetic field sensing expands conducting wire, after current impulse disappearance
The principle of wire contraction, make the icing of conductive line surfaces after conducting wire expansion and contraction repeatedly spalling and drop.Shovel is slided to strike off
Ice is the impulsive force that the impulsive discharge electric current of capacitor is converted to executing agency by the pulsed magnetic field that coil produces, and then will
The icing of conductive line surfaces hits to split and drops.
3. heat ice-melting method.Heating ice-melting method is to utilize the transmission electric current more than normal current density to pass through transmission line of electricity
Caused Joule heat melts the icing of conducting wire, and extreme case is short-circuit ice-melt.Mainly use alternating current and direct current at present
Two kinds of heating de-icing technologies of electric current, the dielectric loss de-icing technology produced using high-frequency and high-voltage excitation also have small range of answer
With.2011, by the research team of Hunan University Wang Yao south institute band and Hunan electric power system Testing ＆ Research Institute, National University of Defense technology etc.
The scientific achievement that multiple mechanisms combine " the new ice-melt of transmission line of electricity, clearing ice technology and the device " that undertakes and complete is melted in power transmission line
Ice played an important role in field.Their newest advanced DC de-icing devices developed, in a plurality of 220 kV
DC ice melting is successfully realized on transmission line of electricity.
These existing achievements in research, are of great significance for removing ice of power transmission line, but these researchs all only will
Research direction has been placed on " deicing after icing ", how not to prevent the correlative study of powerline ice-covering still at present.

Cover, and make to be fitted close between adjacent de-icer boot；After de-icer boot is filled on power transmission line section to be onstructed, that is, complete transformation work
Make.
The improved anti-icing transmission line of electricity of the utility model, 3 body of transmission line of electricity are covered by de-icer boot, run into rain in the winter time
During snowy day gas, rain or snow can only fall on de-icer boot.Upper anti-icing card slot 12 on de-icer boot blocks what is set with in anti-icing card slot 13
Anti-freezing agent block is contacted with sleet, and the solidification point of water reduces（Subzero 20 DEG C or so would generally be reduced to）.Due to for ice and snow,
Actually the process melted and solidified constantly occurs for its surface, because melting equal with the speed solidified（The speed of thawing does not have
Have more than the speed of solidification）, therefore general performance is solid-state.In this way, after solidification point declines, the speed of ice dissolution will exceed
The speed of solidification, even if what is contacted with anti-freezing agent block is solid ice and snow, it also can gradually melt, and melt the water of part along anti-
When ice cover flows downward, solid portion thereon can be driven to come off in the lump, so that ice and snow can not adhere to, accumulate in de-icer boot
On, play actively anti-icing effect.
When running into ice and snow weather through the improved transmission line of electricity 3 of the utility model, the water of thawing by de-icer boot semi-circular tube
2nd, left protective plate 4 and right protective plate 5 flow downward, and are finally flowed down by the bottom of left protective plate 4 and right protective plate 5.Since a left side is anti-
Backplate 4 and right protective plate 5 are outwards set diagonally downward respectively along 2 liang of bases of semi-circular tube respectively, and left protective plate 4 and right protective plate
The back taper of thick lower point is presented in 5 bottom section, therefore water can be flowed down by the tip of reverse taper portion, anti-without going past a left side
It is adsorbed onto again on transmission line of electricity 3 after backplate 4 and right protective plate 5, further prevents water loading and freeze what is adhered on transmission line of electricity 3
Possibility.
Above example is only to illustrative and not limiting the technical solution of the utility model, although with reference to above-described embodiment pair
The utility model is described in detail, it will be understood by those of ordinary skill in the art that：Still can to the utility model into
Row modification or equivalent substitution, without departing from any modification or partial replacement of the spirit and scope of the utility model, it should all
Cover among the right of the utility model.
