Maintenance-free battery group 4 is arranged in position below the frozen soil layer near transmission tower main body 5, and using thin around it
Sand hill is wrapped up in.Photovoltaic solar panel 1 connects maintenance-free battery group 4 by photovoltaic cable.Because the following soil moisture of frozen soil layer is complete
Year change is smaller, and heat dispersal situations are also preferable, is beneficial to extend maintenance-free battery group service life.
Operation principle of the present utility model is as follows：
Direct current caused by photovoltaic solar panel 1 is transmitted to electrical heating plain conductor 2, electrical heating metal by photovoltaic cable
Wire 2, to heat thermostable heat-conductive electronics silica gel plate 3, raises the temperature of thermostable heat-conductive electronics silica gel plate 3 by Joule effect.

Novel ice-covering-proof ability and efficiency, reach more stable and security purpose.
3 thermal responses of silica gel plate of thermostable heat-conductive electronics are fast, heat-transfer capability is strong, temperature raising is good；Safety and environmental protection, electric insulating quality
Can be good；Weather resisteant is extremely strong, both resistance to ozone and ultraviolet radiation, and and can adapts to the adverse circumstances exposed to the sun and rain for a long time, has preferably
Water resistance；There is excellent adhesive force and bonding force to various metal materials, be not easy to peel off；Manually or mechanically applying glue is convenient；
Use economy.
Polytetrafluoroethylene (PTFE) can spend high temperature and long-term works under less than -50 DEG C low temperature conditions hundreds of, and in light weight, ageing-resistant
It is good with chemical stability, corrosion resistance, non-stick, dielectric properties.
The utility model anti-ice cover structure transmission tower anti-ice cover mechanism is as follows：
When supercooled water drop touches transmission tower agent structure component surface, the pole in the process of setting of release latent heat
Easily form icing.Icing is divided into glaze and the major class of rime two, and glaze is dropped while freezing, quality is hard, adhesion is strong, forms ring
Border temperature is -3~0 DEG C；It is -3~-25 DEG C that rime density is small, adhesion is not strong, forms environment temperature.Central China of China
" glaze " weather is most representative.Such as：January 10 to this period by the end of January in 2008, Hunan, Jiangxi, the gas of zhejiang and other places
Temperature is mostly between -5~-1 DEG C；Period precipitation, snowfall are enriched, and meet the meteorological optimum that icing is formed, cause these provinces
Part transmission line of electricity serious icing on a large scale.
Icing is a kind of equilibrium process of heat.Ice cover, ice thickness and freezing fraction etc. both depend on the heat on icing surface
Poised state.The equation of heat balance on icing surface is as follows：
Q1+Q2+Q3=Q4+Q5+Q6+Q7
In above formula：The latent heat discharged when Q1- freezes；Q2- windages are heated to the water droplet of ice face；Q3- ice cools down from 0 DEG C
To the heat of icing surface steady temperature release；Q4- icing surface and the convection heat losses of air；The surface evaporation of Q5- icing or
Heat loss caused by distillation；Q6- supercooling water droplet temperatures are increased to the heat discharged at 0 DEG C；Heat waste caused by the radiation of Q7- ice faces
Lose.
As seen from the above equation, as long as the heat ＞ Q6 that the utility model thermostable heat-conductive electronics silica gel plate provides, avoid being subcooled
But water solidifies in a short time, and supercooled water just can not largely be gathered in the less tower structure component surface in section, so that it may anti-
Only Q1 largely discharges, so as to reach ice-covering-proof purpose.
In general, 1mL water is 20~25 drops, so a drop water is exactly 0.04~0.05mL.One drop water by 0.05mL,
If the thick calculating of 1mm, two, which drip, can cover surface of solids 1cm2Area.
One drop -3 DEG C of supercooled waters be heated to 0 DEG C, it is necessary to heat it is as follows：
Q6=0.05mL × 1000kg/m3× 4.18kJ/ (kg DEG C) × 3 DEG C=0.6J,
Calculated by 1 piece of nominal output 300W photovoltaic panel, 500 can be heated in the 1s times altogether and dripped or 250cm2Tower structure structure
Part surface area.
Therefore, heat provided by the utility model is far longer than this part sensible heat amount of Q6, therefore can reach the effect of anti-ice cover
Fruit.
The utility model is used caused by photovoltaic solar panel on DC current heating transmission tower structural elements surface
Supercooled water, to reach ice-covering-proof purpose.Due to DC current do not consume in the transmission it is idle, and the resistance R of transmission line of electricity≤
Reactance X, so DC ice melting mode relatively can export bigger ice melting current with the exchange ice-melting mode of voltage class.
Anti-ice cover structure transmission tower that the present embodiment provides is mainly used in light ice formation, and (i.e. ice covering thickness is less than 10mm
Area), middle ice formation (i.e. ice covering thickness be more than 10mm be less than 20mm area).
The utility model is adapted to tower more.Steel tube tower exists so that its wind load Shape Coefficient is small with anti-ice cover, wind resistance advantage
Than wide, the utility model is also particularly suitable for this tower structure for application on transmission line of electricity.
For transmission tower main body of different shapes, photovoltaic solar panel 1 can be such as Fig. 3 institutes in transmission tower main body 5
Show in rectangular layout, can also be circular layout as shown in Figure 4 into emitting shape.
