Cable spacer bar with the function of snow removal, dust removal and bird repelling for high-altitude cables

Abstract

The invention discloses a cable spacer bar with the functions of snow removal, dust removal and bird repelling for high-altitude cables. The structure is integrated with an inverse piezoelectric vibration mechanism that is in contact with the high-altitude cable to transmit high-frequency mechanical waves or sound waves to it, and an inductance mechanism that uses the induced magnetic field of the high-altitude cable to obtain an induced current; the inductance mechanism is an inverse piezoelectric vibration mechanism. Power supply; use the structural characteristics of the cable spacer itself, use the electric energy transmitted by the high-voltage transmission line, and obtain a small amount of energy without contact to realize the functions of snow removal, dust removal and bird repelling, with operability, safety, remote control or automatic control It can be installed synchronously with the installation of spacer rods, without additional installation operation, low cost, can effectively prolong the service life of high-altitude cables, and reduce the damage of unfavorable external environment to high-altitude cables.

Description

technical field [0001] The invention belongs to the technical field of cable maintenance, and in particular relates to a cable spacer with the functions of removing snow, dust, and birds for high-altitude cables. Background technique [0002] High-altitude cables carry the heavy responsibility of long-distance power transmission. They are blood vessels for economic development, industrial production, and residential electricity consumption. They cannot be lost. Most of the high-altitude cables are located in remote areas. Therefore, for high-altitude cables, extreme care is required to avoid damage to the cables due to external adverse conditions. The existing high-altitude cables have high erection heights and high voltages, and their quality is required by national standards, which can basically meet the requirements of service life. , and is less considered to be damaged, but there are still some factors in nature that will damage it, reduce its service life, and may even...

[0002] High-altitude cables carry the heavy responsibility of long-distance power transmission. They are blood vessels for economic development, industrial production, and residential electricity consumption. They cannot be lost. Most of the high-altitude cables are located in remote areas. Therefore, for high-altitude cables, extreme care is required to avoid damage to the cables due to external adverse conditions. The existing high-altitude cables have high erection heights and high voltages, and their quality is required by national standards, which can basically meet the requirements of service life. , and is less considered to be damaged, but there are still some factors in nature that will damage it, reduce its service life, and may even cause sudden accidents and cause greater losses. Large, the cable between the two poles is long, and the extra weight of the snow on the cable is a great burden; another example is the birds staying on the cable or cable pylon, their sharp claws are easy to cause damage to the surface of the cable, even a relatively small wound, It is also easy to aggravate corrosion in the external environment for a long time and reduce the life of the cable; the feces excreted by birds are conductors and are corrosive, which will also cause damage to cables or cable towers or cause accidents; The cable with a good surface quality has little effect, but today a lot of dust contains acidic substances, which can easily corrode the cable when combined with rainwater. If there is a wound on the cable surface, the dust will accumulate in the wound and further aggravate the corrosion of the wound; existing There is no effective means of snow removal and dust removal in the technology, and bird-repelling methods generally use bird-proof metal thorns, but on the one hand, the installation cost is high, and on the other hand, it will cause greater damage to birds, so it is not a good method
