Problems solved by technology

However, areas rich in solar energy resources are often remote areas or areas that are far away from grid substation sites and have inconvenient transportation. When solar power plants transmit electricity, they generally use high-voltage long-distance transmission. Therefore, how to solve the maintenance and maintenance of the transmission grid has become a problem. Frequent tasks, especially on snowy day and night in winter, the process transformation of snow, water, and ice due to the change of temperature difference has a strong destructive force on high-voltage transmission lines, often leading to major power outages where cables break and lines are interrupted , which in turn suffers economic and time losses as well as many problems in terms of safety

Abstract

The invention discloses a DCS control power grid power transmission line ice-preventing device. The DCS control power grid power transmission line ice-preventing device comprises an ice removing ring covering a power transmission line. The ice removing ring comprises an inner ring and an outer ring which are connected in a sleeved mode. An induction coil is arranged inside the outer ring, a curved surface rotating pattern is formed on the outer surface of the power transmission line, the surface, making contact with the power transmission line, of the inner ring is provided with a matched thread, and the matched thread is matched with the curved surface rotating pattern in a concave-and-convex mode. When the power transmission line transmits an alternating current, an alternating magnetic field around the power transmission line produces a current inside the induction coil, and a magnetic field generated by the current is interacted with the alternating magnetic field to produce the rotating push force to push the inner ring to drive the whole ice removing ring to rotate and move in the rotating direction of the surface of the power transmission line to remove the ice and snow. The Lenz's law electromagnetic induction principle is applied, the DCS control power grid power transmission line ice-preventing device rotates surrounding the power transmission line like the fact that a nut surrounds a bolt, and moves to scrape the residual snow ice and snow in the moving direction of the power transmission line, and the purpose of applying the device is achieved.

Description

technical field [0001] The invention relates to a power transmission line safety device, in particular to a DCS control power transmission line anti-icing device. Background technique [0002] As an important part of the new energy industry, the solar power generation industry has great potential for development and competitive advantages in environmental protection technology, and has broad prospects for future development. However, areas rich in solar energy resources are often remote areas or areas that are far away from grid substation sites and have inconvenient transportation. When solar power plants transmit electricity, they generally use high-voltage long-distance transmission. Therefore, how to solve the maintenance and maintenance of the transmission grid has become a problem. Frequent tasks, especially on snowy day and night in winter, the process transformation of snow, water, and ice due to the change of temperature difference has a strong destructive force on ...
