The invention discloses a system for monitoring and suppressing wind vibration of a transmission line conductor, the system comprises a mechanical connection system for fixing the wind vibration monitoring and suppression system for transmission line conductors on a cross arm of a transmission line tower; a power generation and energy storage system for generating and storing electric energy by cutting a magnetic inductance line between two magnetic poles using kinetic energy generated by wire wind vibration; a conductor wind vibration suppression system is used for suppress that lead wind vibration; and a conductor monitoring and signal transmission system is used to detect the conductor and its surroundings and transmit the signal to the power grid headquarters. The invention integratesmechanical energy power generation technology, air inlet valve control technology and real-time monitoring technology, has good power generation performance, is suitable for a wide range of meteorological regions and has strong stability of a magnetic fluid power generation system. The wind vibration suppression system of the conductor can suppress the wind vibration; and the system has the advantages of simple structure, convenient maintenance and low manufacturing difficulty, good adaptability to various transmission lines, extensible function and wide application, and reasonable structureand reliable performance.
Description
technical field [0001] The invention relates to the technical field of wind prevention and disaster reduction for transmission lines, in particular to a wind vibration monitoring and suppression system for transmission line conductors. Background technique [0002] Under the action of wind load, the wire will produce various forms of vibration. Including conductor wind vibration, breeze vibration, sub-gap vibration and other forms, it is a serious disaster that endangers the safe and stable operation of transmission lines. The wind vibration of the conductor will cause flashover tripping, damage to hardware and insulators, broken strands of conductors, broken wires, loosening and falling off of tower bolts, damage to tower materials, damage to the foundation, and even tower collapse and other serious accidents. Among the natural disasters that trigger power systems, wind disasters are the most serious. In recent years, with the expansion of the scale of my country's power ...
