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 composite galloping-inhibiting spacer with variable damping grip strength. The spacer comprises a first box body, second box bodies are fixedly arranged at the upper end andthe lower end of the first box body, non-damping wire holding arms are fixedly arranged at the two sides of the first box body, wire holding arm damping units are arranged in the second box bodies, and elastic elements are arranged at the two sides of the wire holding arm damping units. The wire holding arm damping units can swing along the outer wall of the first box body, and meanwhile 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 ...
