Abstract
Description
Technical Field
[0001] The present invention relates to the field of anti-icing of power distribution network lines, and in particular to a vibration anti-icing device and system for power distribution network lines. Background Art
[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
[0003] When the distribution network lines are covered with ice to a certain extent, their conductivity will be affected. In severe cases, they may even cause accidents such as broken wires and poles, and short circuits between phases, which will have a serious impact on electricity consumption in production and life. However, light ice will not affect the safe and stable operation of the lines, so it is particularly important to take certain measures to prevent the formation of severe ice. In areas with complex terrain, such as mountainous areas and plateaus, the ground is slippery and trees and bamboos fall down in icy and snowy weather, making it difficult for vehicles to reach and for people to enter. At this time, it is extremely difficult and safe to transport de-icing tools and maintenance materials to de-ice and repair the iced distribution network lines. If there is more than one cold wave in winter, multiple de-icing will be required, which will consume manpower and financial resources.
[0004] The existing de-icing methods include: 1. manual ice knocking or heavy-loaded drones using popsicle sticks to knock ice; 2. blank cartridge vibration de-icing; 3. DC ice melting device for ice melting; among them, the manual ice knocking de-icing method has high labor intensity and high risk; drones need to be operated by special personnel and are not suitable for clearing freezing rain type ice (tight adhesion); blank cartridge vibration de-icing still has certain safety risks during operation, and the impact force is difficult to control accurately, which may cause damage to the wires; DC ice melting devices are costly and technically difficult, and require power outages to melt ice; at the same time, the above three de-icing methods all wait until the ice has formed or is relatively serious before de-icing, which is difficult to de-icing and has high safety risks. Summary of the invention
[0005] The purpose of the present invention is to provide a distribution network line vibration anti-icing device and system for the problems existing in the prior art. The device is installed on a pole tower and acts on the conductor near the pole tower. The device continuously vibrates at a certain frequency and amplitude for a period of time to drive the conductor to vibrate, and the vibration wave is generated to propagate along the conductor to shake off water droplets, snow, and light ice on the conductor, thereby preventing ice from forming on the conductor. The system integrates remote ice observation, ice prevention, and ice removal. It observes the environmental status and analyzes it for early prediction and prevention. Before ice is about to form, it shakes off water droplets and snow by vibrating the conductor, and shakes off the ice layer when thin ice is formed, avoiding the formation of thick ice and heavy ice, and ensuring the safe and stable operation of the distribution network's easy-to-ice lines.
