Description
Technical field
The utility model relates to power system transmission line wire measurement techniques fields more particularly to a kind of icing shape to survey
Measure device.
Background technique
China is the country that transmission line of electricity accident is more in the world, and powerline ice-covering is likely to result in transmission line of electricity g-load
Load, insulator chain icing flashover, conductor galloping and the uneven icing of generation or the not same period deice accident, to cause huge
Economic loss and serious social influence.Domestic icing on-line equipment is many kinds of at present, main icing monitoring mode
It is following several:
1. video image method: this scheme be shoot picture by being mounted on shaft tower video camera, and by GPRS/
GSM transmission, artificial the case where judging live icing according to picture.The shortcomings that this method is can only to observe that transmission line of electricity covers
The case where ice, this method are unable to judge accurately out the severity of icing.
2. weight method: measuring the quality of vertical shelves inside conductor by tension sensor, and according to wind speed, wind direction, insulator
The data such as string inclination angle, calculate the tilt component of air resistance coefficient and insulator chain, finally obtain icing quality.Algorithmically lead
It will be according to transmission line status equation.The disadvantage is that there are device long-term works for the tension sensor method based on resistance strain gage
The problem of stability and reliability, it is most important that the error that it is measured is also big, causes result very inaccurate.
3. Horizontal Tension --- strain section insulator chain axial tensile force and hitch point tilt-angle method: are measured by tension sensor
Inclination data obtains icing quality.The disadvantage is that icing situation when can only measure stable state, when installation, needs to change strain section
The structure of insulator chain, it is possible to bring the hidden danger in structure.
4. the mathematical model based on thermodynamics mechanism.By establishing wire icing thermodynamics energy balance relations, obtain
The parameters such as criterion, ice thickness calculating formula and ice weight growth rate that conductive line surfaces freeze.Have ignored conductive line surfaces roughness, existing icing
Influence of the shape to icing process.The disadvantage is that the characteristics and details of icing process cannot be disclosed, cannot embody dependent interaction because
The influence of element is only for " black box " emulation of interpretation of result.
Existing icing on-line monitoring technique stability is to be improved, and mechanical transmission component is easy to freeze, and monitoring parameters are not
Entirely, the timeliness and accuracy of monitoring result are especially reduced under adverse weather condition.Therefore reinforcing covering transmission line of electricity
The real-time monitoring of ice damage misfortune, make in time prevent the reply method of icing calamity very it is necessary to.
And at present almost all of evaluation method have one it is common it is assumed that thinking that the icing shape of conducting wire has
One circular cross section.However this hypothesis is not often inconsistent with the practical icing situation of most of transmission lines of electricity.After wire icing
Cross-sectional shape points 7 kinds: circle, ellipse, sector, comb-shape, aciculiform, box-like and waveform.For ice coating wire,
The cross section of round or ellipse is more common.If it is non-circular to calculate to melt the evaluation method of time using round ice coating wire ice
The ice of shape ice coating wire melts the time, it will generates certain deviation, under special circumstances, even results in estimated value and be not inconsistent reality completely
Border.Therefore, the shape feature for analyzing wire icing has great importance.
But there are following defects for icing measuring device now on the market;
Current icing monitoring technology have one it is common it is assumed that thinking the icing shape of conducting wire with a circle
Cross section.It can not intuitively reflect the thickness of icing and the shape feature of wire icing.
Icing on-line measurement device measuring result error is larger and is affected by wind speed, line span, can not be icing
Prediction model provides accurate field data；Its cold operation stability is poor, and online rate is low；It has a single function, and scalability is poor.
In conclusion needing a kind of icing form measuring instrument for being able to solve the above problem on the market now.
