Damping spacer for six split wires

Abstract

The invention discloses a damping type spacer of a six-split conductor. The damping type spacer of the six-split conductor comprises six spacer monomers connected end-to end to form an annular structure, each spacer monomer comprises a pair of connecting arms and a conductor locking device; a fixed locking hook is arranged at the end part of the conductor locking device, the fixed locking hook isconnected with a movable locking hook, springs uniformly distributed in arc are arranged the inner sides of the fixed locking hook and the movable locking hook; a buffer layer is arranged at the otherend of the spring; an oval through hole is formed on a connecting arm, a tenon end and a groove end are respectively arranged at two ends of the spacer monomer, an L-shaped tenon is arranged at the tenon end, and an L-shaped groove matched with the L-shaped tenon is arranged on the groove end. The spacer disclosed by the invention has the advantages of being convenient for transportation, high instability and long in service life.

Description

technical field [0001] The invention relates to a spacer, in particular to a damping type spacer with six split wires. Background technique [0002] When erecting ultra-high voltage transmission lines, in order to suppress corona discharge and reduce line reactance, the erection method of split wires is generally adopted. With the different transmission voltages, split wires need to adopt two-split, four-split, six-split, and eight-split types. In order to maintain the geometric shape of the split wire, the split wire of the power transmission line needs to use a spacer to limit the relative movement between the sub-wires. The existing low-split wire spacer development technology is relatively mature. At present, the spacers of six-split, eight-split and other high-split conductors are all one-piece structures. Due to their large shapes, they bring great troubles to manufacturing and transportation, and in some strong wind areas, the existing spacers The vibration and colli...

Problems solved by technology

[0002] When erecting ultra-high voltage transmission lines, in order to suppress corona discharge and reduce line reactance, the erection method of split wires is generally adopted. With the different transmission voltages, split wires need to adopt two-split, four-split, six-split, and eight-split types. In order to maintain the geometric shape of the split wire, the split wire of the power transmission line needs to use a spacer to limit the relative movement between the sub-wires. The existing low-split wire spacer development technology is relatively mature. At present, the spacers of six-split, eight-split and other high-split conductors are all one-piece structures. Due to their large shapes, they bring great troubles to manufacturing and transportation, and in some strong wind areas, the existing spacers The vibration and collision between the rod and the sub-conductor are fierce, the stability is low, the cushioning effect is poor, and the wear between the spacer and the sub-conductor is serious, which greatly reduces the service life of the spacer

Therefore, the existing spacers have the problems of difficult transportation, low stability and short service life
