Background

The split conductor can change the magnetic field distribution around the conductor, so that the radius of the conductor is increased, and the reactance of the conductor is reduced, so that the split conductor has good electric energy transmission characteristics, and the split conductor is widely applied to high-voltage transmission lines. However, wind-induced galloping disasters such as gravity, wind power and the like cause wind-induced galloping disasters such as subspan oscillation, icing galloping and the like of the power transmission line, and great threats are caused to safe and stable operation of a power grid. At present, a 220KV transmission line and a 330KV transmission line adopt a two-split conductor, a 500KV transmission line adopts a three-split conductor and a four-split conductor, and an ultrahigh voltage transmission line with voltage higher than 500KV adopts a six-split conductor and a more-split conductor. In order to ensure that the distance between the split conductor harnesses is kept constant to meet the electrical performance, reduce the surface potential gradient and avoid electromagnetic force between the conductor harnesses to cause mutual attraction collision under the condition of short circuit or cause instant attraction collision, but the normal state can be recovered after the accident is eliminated, so that the spacing rods are arranged in the span at a certain distance. The installation of the spacer bar can also play a certain role in inhibiting the oscillation of the secondary span and the breeze vibration. However, the length of the existing spacer is relatively fixed, and the length of the spacer cannot be adjusted to a certain degree, so that the spacer cannot be suitable for various occasions.
