Abstract
The utility model discloses an auto-operating de-icing transmission line, comprising a wire-erecting pole, a steel twisted stay wire, a hanging buckle and a cable. The auto-operating de-icing transmission line is characterized in that: the cable is suspended below the steel twisted stay wire via the hanging buckle, an electric heating layer is covered on the periphery of the steel twisted stay wire, and the electric heating layer is connected with an auto-control power supply. The auto-operating de-icing transmission line disclosed by the utility model can automatically control the system to operate according to external environmental conditions; simultaneously, because the electric heating layer is located on the steel twisted stay wire, the overall temperature of the transmission line can be effectively ensured to be higher than freezing-point temperature, and the insulating layer of the transmission line can be ensured not to be contacted with a heat source, thus effectively avoiding the damage of high temperature on the insulating layer of the transmission line.
Description
Technical field
The utility model relates to a kind of self-operating deicing power transmission line, belongs to the power transmission and transformation field.
Background technology
Along with high speed development of national economy, all trades and professions are increasing to electricity needs, require increasingly high to power supply quality.But because relations such as geographical position, weather conditions; China's some areas winter temperature is generally lower; Supply line all has icing situation in various degree to occur; When serious even occurred breaking the major accident of transmission line, having a strong impact on transmission of electricity safety and power supply quality, and causing tremendous loss because of circuit freezes.
Summary of the invention
The utility model purpose just is to overcome above-mentioned deficiency, and a kind of self-operating deicing power transmission line is provided.
For addressing the above problem, the utility model is to realize through following technical scheme:
The self-operating deicing power transmission line comprises stringing bar, the backguy of steel strand, buckles and cable, it is characterized in that: said cable is suspended on steel strand backguy below through buckling, and steel strand backguy periphery coats electric heating layer, and electric heating layer is connected with microcomputer controlled power supply.
The self-operating deicing power transmission line; Its microcomputer controlled power supply comprises low-tension supply terminal, A.C. contactor, temperature sensor, humidity sensor and control module; Control module is connected with ac contactor coil, temperature sensor, humidity sensor respectively, and low-tension supply terminal and electric heating layer are connected with contact, A.C. contactor both sides respectively.
The self-operating deicing power transmission line, its electric heating layer is coated by insulating material.
The order of the utility model structure; And realized moving according to the external environmental condition automatic control system; Electric heating layer is positioned in the backguy of steel strand simultaneously; Both can guarantee effectively that the transmission line bulk temperature was higher than freezing point temperature, and can guarantee that again the transmission line insulating barrier did not contact with thermal source, thereby effectively avoid the broken ring of high temperature the transmission line insulating barrier.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is steel strand guy section figure;
Fig. 3 is the utility model electrical control block diagram.
Embodiment
Like Fig. 1, self-operating deicing power transmission line shown in 2 and 3, comprise microcomputer controlled power supply 1, stringing bar 2, the backguy 3 of steel strand, buckle 4, electric heating layer 5 and cable 6 that wherein cable 6 is suspended on steel strand backguy 3 belows through buckling 4; Steel strand backguy 3 peripheries coat electric heating layer 5, and electric heating layer 5 is connected with microcomputer controlled power supply 1.
During use, freeze when critical when ambient temperature and humidity reach to preset, this deicing system brings into operation; The electricity heating layer begins to heat; Through electric heating layer thermal radiation the spatial dimension that comprises power transmission cable is heated, guarantee temperature, freeze thereby stop cable above freezing.Do not freeze when critical when ambient temperature and one or two of humidity all reach to preset, this system is out of service.
