Description

Split conductor spacing device for power transmission line

Technical Field

The utility model relates to a transmission line auxiliary assembly technical field specifically is a split conductor spacer for transmission line.

Background

At present, the split conductor can change the magnetic field distribution around the conductor, thereby equivalently increasing the radius of the conductor and reducing the reactance of the conductor; and meanwhile, the electric field distribution around the lead is also changed, so that the susceptance of the lead is correspondingly increased (because the current-carrying capacity of the conductor is in direct proportion to the heat dissipation capacity of the conductor, and the heat dissipation capacity is related to the surface area of the conductor). The voltage drop is reduced, and the natural power factor of the line is effectively improved, so that the electric energy quality of the medium and low voltage power grid is improved.

Patent application publication No. CN 201720885958.2 discloses a split conductor spacer structure that is suitable for use in a compact split conductor spacer structure. Because the supporting frame and the wire gland enclose a closed wire clamping hole, the closed wire clamping hole can improve the corona starting voltage of the split conductor spacer.

Although the above-mentioned patent scheme has solved the shortcoming of traditional split conductor spacer for transmission line, this scheme still has some shortcomings: 1. most of the existing split conductor spacing devices for the transmission lines can only be suitable for the transmission lines of one number of lines, so that the applicability of the device is poor; 2. the clamping device of the existing split conductor spacing device for the power transmission line is complex and inconvenient to operate and control, and meanwhile, the reliability of the clamping device is low, so that certain potential safety hazards exist when the device is used. Accordingly, we propose a split conductor spacing device for power transmission lines.
