Embodiment Construction

[0019] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in this specific embodiment. Obviously, the implementation described below Examples are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in this patent, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this patent.

[0020] As shown in the drawings, a three-phase support and insulation device for distribution lines includes a support plate 1, and the support plate 1 is provided with an annular track 2 surrounded by an outer ring 22 and an inner ring 21. Three first screw holes 11 are evenly distributed, and the three first screw holes 11 are opened on the support plate 1 . A second screw ho...

Abstract

A distribution line three-phase support insulation device provided by the invention comprises a supporting disc, an annular track is arranged on the supporting disc, and three first screw holes are uniformly distributed in the annular track; the supporting disc is provided with three insulating supporting assemblies rotating around the annular track, and the free ends of the insulating supporting assemblies are provided with connecting assemblies for supporting and fixing a distribution line; and the insulation supporting assembly comprises a first insulation supporting rod and a second insulation supporting rod connected through a damping spring, and a first bolt matched with the first screw hole penetrates through the first insulation supporting rod. The three insulation supporting assemblies are fixed on the supporting disc through bolts and are fixed with the wire support through the connecting assemblies to form triangular support fixation, so that the sag of the whole line is reduced. The damping spring can buffer the galloping wire and then reset in time, so that the problem of tripping caused by contact of the wire is avoided, and meanwhile, the galloping range is prevented from being extended and expanded.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering equipment, in particular to a three-phase support insulation device for distribution lines. Background technique [0002] In recent years, in 10KV distribution network lines, insulated wires have widely replaced the application of bare wires, but large-span bare wires still account for a large proportion of the distribution network. The hazards caused by the contact of large-gauge bare conductors in the distribution network are various. The light ones cause flashovers and trips, and the severe ones cause damage to hardware and insulators, broken strands of conductors, broken wires, loosening and falling off of tower bolts, and even downturned poles. lead to major power grid accidents. Judging from the statistical analysis data of overhead line accidents in recent years, the problem of long-gauge conductor contact has become one of the most important factors threatening line saf...
