ROLL SUPPRESSOR FOR SUPPRESSION OF POWERFUL TRANSMISSION LINE CONDUCTORS GALLOPING

摘要

The invention relates to electric mains, in particular – to distribution of electric energy, specifically – to surface-mounting laying electric cables or powerful power transmission lines (ETL) having large passages. A roller suppressor for galloping suppression of powerful power lines (ELT) comprises an upper working surface of a bottom bed plate made horizontal and two-dimensional. Two intermediate cylindrical bodies are installed on said plate symmetrically relative to an insulator chain, each of which has an axial hollow inside, a tooth profile outside and an axle perpendicular to the bottom bed plate plane, and is joined relatively to two symmetric supports made as ears on arms rigidly connected relative to the bottom bed plate, bearings are pressed to each ear for free rotation of the intermediate cylindrical body therein. Into the axial hollow of each cylindrical body a resilient member and an axial rod are located, the axial rod has a thread on both ends for retaining nuts to adjust strength of the resilient member. The axial hollow of each cylindrical body is closed on both sides by shoes with through holes for the axial rod. The length of each rod does not exceed the whole length of the cylindrical body with shoes. The working body is made as the upper bed plate of variable mass with two arch recesses on the lower surface thereof with a toothed profile for interaction with the tooth profile of the corresponding intermediate bodies, for friction engagement with the cylindrical body shoes, the upper bed plate has demountable side surfaces made as plates with L-shaped limiter in points contacting to the shoes; said plates has through windows to regulate the corresponding resilient members of the cylindrical bodies in the point of axial rods location on butt ends of each shoe. The technical result is growth of suppressor reliability and fail-safety, providing optimal adjustment thereof.
