Embodiment Construction

[0022] The core of the present invention is to provide an interphase spacer, which effectively solves the technical problem of wind protection in the power distribution system of a wind farm, reduces the degree of equipment loss, reduces the scope of accident shutdowns, and shortens the fault Eliminate time and reduce economic losses.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Please refer to figure 1 , figure 1 It is a schematic structural diagram of the interphase spacer bar provided in a ...

Abstract

The invention discloses a phase-to-phase spacer. The spacer is connected between two wires and comprises a phase-to-phase spacer insulator (4), a length adjusting device (8) connected with a first endof the phase-to-phase spacer insulator (4) and two wire clamps (7), wherein the two wire clamps (7) are connected with a second end (3) of the phase-to-phase spacer insulator (4) and the other end ofthe length adjusting device (8), and the two wire clamps (7) are connected with the two wires respectively. Aiming at the line galloping problem, the phase-to-phase spacer has the advantages that thetechnical problem about wind prevention for a power distribution system of a wind farm is effectively solved, the equipment loss degree is reduced, the accidental shutdown range is reduced, troubleshooting time is shortened, and the economic loss is reduced.

Description

technical field [0001] The invention relates to the technical field of line protection devices, in particular to an interphase spacer. Background technique [0002] Due to the different installation methods and climatic conditions of the high-voltage power transmission and distribution lines, the phase-to-phase wires dance in different directions, and the force is complex. Reliability and safety of transmission line operation. [0003] For example, wind farms located in coastal areas are located in the subtropical monsoon region and are affected by the Pacific Ocean and oceanic climate, and are one of the areas frequently attacked and passed by tropical cyclone activities. Every year from April to November, typhoons may land, mostly in July, August, and September. They first appear in April and the latest in November. According to statistics, there are an average of 1.5 typhoons each year. Wind farm power equipment is damaged to varying degrees every year due to typhoons a...
