The invention discloses a high-voltage power transmission multi-split line galloping-prevention counter weight. A left connecting arm and a right connecting arm are connected together through a left-right arm fixing bolt; two lower conductor lines pass through conductor line fixing gum covers; line clamps and the left connecting arm and the right connecting arm are fixed together through line clamp fixing bolts; the other end of each line clamp is connected with each line clamp lifting lug base; horizontal tail ends of the left connecting arm and the right connecting arm are connected with fixed horizontal hammer heads, and lower ends are connected with lower hammer heads; a connecting arm slot is formed at a connecting end of each of horizontal hammers and lower hammer heads, a blot fixing end slot is formed at a corresponding end of the connecting arm slot, hammer head fixing bolts are fixedly connected with each connecting arm bolt hole through hammer fixing holes; the left connecting arm, the right connecting arm and the line clamps are made of aluminum alloy; the horizontal hammer heads and the lower hammer heads are made of cast iron, and the weight of the horizontal hammer heads is less than that of the lower hammer heads, thereby reaching the balance of the connecting, the weight of the lower hammer heads is large, thereby reaching the aim of restricting the swing potential energy of two lower conductor lines.
Description
technical field [0001] This patent relates to the technical field of safety protection for ultra-high voltage transmission lines, in particular to an anti-galling counterweight for multi-split high-voltage transmission lines. Background technique [0002] At present, most ultra-high voltage transmission lines use multi-split conductors such as four-split and six-split conductors. In some areas, large-span tower distances are used. Due to the effect of wind blowing, the conductors will swing with the wind. This kind of irregular swing is called the "dancing" of the line. In order to prevent the wind from blowing the line, people have adopted many methods: such as adding rubber rings at the fixed points of the split rods to fix the clamps, and using rubber rings to prevent the line from dancing. The damping effect reduces the vibration capacity of the wire, and there are ways to increase the weight at the lower end of the split rod to eliminate the potential energy of the wire...
