Description
Technical field
The present invention relates to monitoring transmission line icing field, more particularly to a kind of carrying is covered based on the transmission line of electricity of high-definition image
Ice thickness computational methods and system.
Background technology
Powerline ice-covering is the significant threat of electric power netting safe running, and serious icing will cause huge economic loss,
Therefore the monitoring and early warning that must carry out ice-covering area powerline ice-covering snow works, and icing density is eliminated in bud, protects
Barrier Ice Area line security operation.Ice of seeing artificial at present is sent out as the Main Means that line ice coating is monitored in the work of anti-icing anti-ice
Important function is waved, but in actual applications, there is following 4 aspects in artificial ice of seeing：
(1) live low visibility affects artificial sight ice result.Northern cold gas are gone down south and are met shape with southern warm moist air
Into cold front, substantial amounts of ice crystal, snowflake will be formed in atmosphere, and cause surrounding visibility to be decreased obviously, now exactly transmit electricity
The line ice coating growth rate most fast period.But due to live low visibility, anti-icing personnel are universal during artificial sight ice
Reflection cannot see the icing situation of the lead wire and earth wire of shaft tower eminence clearly, can only take the mode of estimation, and Near Ground is planted because of ground
Insulation and the effect of underground heat, do not observe icing substantially, cause manually to see ice having difficulties.
(2) analog conducting wire sight ice thickness is variant with eminence lead wire and earth wire icing.Main cause is that analog conducting wire is in
Near Ground, weather environment is different from eminence.Air is acted in Near Ground flow process by ground friction resistance,
Wind speed the closer to ground is less；Simultaneously ground is due to effects such as underground heat, vegetation insulations, and Near Ground temperature is higher.Two is mould
Intend wire no current to pass through, without heat effect.Generally the model of analog conducting wire is consistent with shaft tower wire type, but operation
In wire can produce heat effect due to aliving, icing process may be with analog conducting wire difference.
(3) shaft tower eminence is larger with the column foot temperature difference.The artificial scope for seeing ice is actually led mainly near observation tower column foot
Ground wire is in shaft tower eminence.Shaft tower eminence can significantly affect respective icing process with the temperature difference of column foot.According to experience table
Bright, when generally cold wave is passed through, first there is icing in shaft tower eminence, and icing occurs in column foot will postpone 1～2 day；Cold wave disappears
When, the ice-melt of shaft tower eminence is deiced more rapidly, and the natural ice-melt of column foot need to be through the longer time.This phenomenon is to artificial
That sees ice brings certain difficulty.
(4) it is lack of standardization that the ice sample that drops surveys ice.Ice, tower material are seen with analog conducting wire see the mode phase such as ice and scene estimation ice thickness
Than shaft tower lead wire and earth wire drops ice sample survey ice result with higher accuracy.But, during the ice sample that drops surveys ice, by
In the guidance for still lacking associated specifications book, there are certain mistaken ideas in measuring method.Ice sample is such as will fall off still with length shot
Or the mode of weight method survey ice thickness calculates ice thickness, cause survey ice result less than normal；Directly surveyed during ice thickness with slide gauge, it is not many
Secondary measurement is averaged, and causes survey ice result under-represented；The ice sample that drops surveys ice not in time, after ice sample drops after 1～2 day
The problems such as just measuring.
