Problems solved by technology

However, most of the current damping spacers use rubber as the damping material at the movable joints of the spacer to dissipate the vibration energy of the wire.
The inventors found that the traditional method of using rubber to eliminate line vibration and energy consumption has a single form, which cannot achieve various forms of energy consumption and vibration reduction, and the anti-galling effect is limited.
In the outdoor working environment, rubber products are prone to corrosion and aging, which will increase the friction between the hardware and the wires, which will easily cause disconnection and dropouts, and power failures

Abstract

The invention discloses a compound dance-suppressing spacer bar with variable damping grip force, which comprises a first box body, a second box body is fixed at the upper and lower ends of the first box body, and non-damping holding bars are fixed at both sides of the first box body. For the wire arm, a wire holding arm damping unit is arranged in the second box, elastic elements are arranged on both sides of the wire holding arm damping unit, the wire holding arm damping unit can swing along the outer wall of the first box, and the elastic element provides damping to reduce vibration.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings and vibration reduction of transmission lines, and in particular relates to a compound galling-suppressing spacer with variable damping grip. Background technique [0002] When the transmission line encounters heavy rain or other bad weather conditions, it will produce a large galloping phenomenon. The galloping of the line will cause the line to trip, which will cause electrical failure. In addition, it will also cause damage to fittings, insulators, jumpers, and wires. Broken strands, broken wires, damaged tower materials and foundations, loose bolts and other serious mechanical damages, resulting in serious power transmission accidents. The spacer bar is an essential component installed on the split conductor of the transmission line. The main purpose of split conductor spacers in transmission lines is to limit the relative movement between the sub-conductors and to maintain th...
