Anti-oxidation counter weight device resistant to self-excited vibration for high voltage overhead transmission line

Abstract

The invention discloses an anti-oxidation counter weight device resistant to self-excited vibration for a high voltage overhead transmission line. The anti-oxidation counter weight device comprises counter weight sheets and is characterized in that the counter weight sheets are provided with counter weight sheet installation barrels relatively matched with the counter weight sheets, and each counter weight sheet installation barrel is mainly composed of a barrel body, a barrel cover and a barrel bottom. A sleeving hole A is formed in the middle of each counter weight sheet, the two sides of the counter weight sheet are respectively provided with a sleeving hole B, the cross sections of the sleeving hole A and the sleeving hole B are respectively circular, and the diameter of the sleeving hole A is larger than that of the sleeving holes B. The anti-oxidation counter weight device is simple in structure and ingenious in design. A traditional counter weight sheet is simply transformed. The additional counter weight installation barrels matched with the counter weight sheet enable the counter weight sheets to be prevented from being in contact with the outside, and the counter weight device is resistant to oxidation, corrosion and the like. Meanwhile, the counter weight device is convenient and fast to install, and supporting rods are arranged between the counter weight sheets, so that the counter weight sheets fit firmly.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an anti-oxidation and anti-dancing weight device for high-voltage overhead transmission lines. Background technique [0002] At present, the quality requirements for all aspects of transmission lines are very high, because the safety of transmission lines is very important, otherwise it will cause great safety hazards. Among them, anti-galling of transmission lines is a problem that has attracted attention in recent years. Galloping refers to the self-excited vibration of the wire with low frequency (0.1Hz-3Hz) and large amplitude (up to 10m or more). With the extensive application of composite insulators for overhead transmission lines, especially the hanging strings of tension pole and tower drainage wires, composite insulators are light in weight and poor in wind deflection resistance, and wind deflection discharge accidents are prone to occur, so it is necessary to i...

Problems solved by technology

However, there are defects in the existing structural design of the heavy hammer. Only one set of holes is set in the center. When installing the heavy hammer, it is time-consuming and laborious. The structure is not easy to bind, it is inconvenient to pass up and down, and it is easy to fall off, which may lead to safety accidents

At the same time, the traditional heavy hammer is easily oxidized and corroded if it is exposed to the outside for a long time.
