Abstract

The invention relates to the technical field of power distribution equipment protection devices, and particularly relates to a composite phase-to-phase spacer comprising two insulators which are symmetrically arranged. Flexible mechanisms are arranged between the two insulators. One end, which is away from the flexible mechanisms, of each insulator is fixed on a lead through a wire clamp. The flexible mechanisms comprise an upper supporting plate and a lower supporting plate. Three elastic mechanisms and the lower supporting plate form a tetrahedral structure. A guide block is provided with multiple air holes. Internal cylinders are connected on the bottom part of the upper supporting plate through spherical hinges. An external cylinder is connected on the top part of the lower supporting plate through the spherical hinge. The top ends of the three internal cylinders are converged at one point. The energy of vibration generated between two leads is absorbed by a spring. The device uses the tetrahedral flexible structure, and the interfaces are connected by the spherical hinges so that the situation of breaking of the device can be effectively avoided, use is firm and safe, installation is quite convenient, the applicability is higher and the time of high-altitude work can be reduced for the workers.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment protection devices, in particular to a composite interphase spacer. Background technique [0002] Line accident refers to the sudden interruption of line power supply due to various reasons. The common transmission line faults include transmission line wind deflection flashover fault, lightning tripping, lightning strand breaking, line icing fault, line pollution flashover, line external force damage fault, line bird damage fault and so on. [0003] When the wind blows to the overhead transmission line with a non-circular cross-section due to ice coating, it will generate a certain amount of aerodynamic force, which is easy to induce a low-frequency, large-amplitude self-excited oscillation of about 0.1-3Hz in the line. In terms of vibration form It is manifested as only one or a few half-waves in a span, which is called galloping. Galloping is extremely harmful to overhead ...
