Split conducting wire assembly type anti-galloping spacer

Abstract

The invention discloses a split conducting wire assembly type anti-galloping spacer, which comprises a spacer frame, supporting arms and a wire clamping device, and is characterized in that the spacer frame is provided with a plurality of connecting pipes arranged at equal angles, the number of the connecting pipes is at least two, a slot is formed in one end of the connecting pipe, one end of the supporting arm is detachably connected with the connecting pipe, the wire clamping device is arranged at the other end of the supporting arm and comprises a first wire clamping plate and a second wire clamping plate, the first wire clamping plate and the second wire clamping plate define a cylindrical structure, one end of the first wire clamping plate and one end of the second wire clamping plate are hinged through a hinge, and the other ends of the first wire clamping plate and the second wire clamping plate are connected through a lock. According to the invention, the spacer frame and the supporting arms are arranged to be of a detachable assembly type structure, when the spacer is installed on split conducting wires, the supporting arms and the split conducting wires can be installed one by one through the wire clamping devices, and then the tail ends of the supporting arms are connected with the spacer frame, so that the labor intensity of installation personnel is reduced, and the danger that an installation worker carries a heavy object to construct at a high position is reduced.

Description

technical field [0001] The invention belongs to the technical field of cable erection, and in particular relates to a split wire assembly type anti-dancing spacer. Background technique [0002] Two, four or more split conductors are used for each phase conductor of long-distance and large-capacity EHV transmission lines. At present, 220KV and 330KV transmission lines use two-split conductors, 500KV transmission lines use three-split and four-split conductors, and ultra-high voltage transmission lines with voltages higher than 500KV use six-split and more split conductors. In order to ensure that the distance between the split wire harnesses remains unchanged to meet the electrical performance, reduce the surface potential gradient, and in the case of a short circuit, the electromagnetic force will not be generated between the wire harnesses, causing mutual attraction and collision, or even if the instantaneous attraction collision is caused, but after the accident is elimina...
