Abstract

The invention discloses a Coulomb-force-traction spherical compression jet airflow arc-extinguishing device and a sphere type arcing horn. The Coulomb-force-traction spherical compression jet airflowarc-extinguishing device is mainly composed of upper and lower hemispheres, wherein the upper hemisphere is a Coulomb-force arc-striking metal hemisphere, and the lower hemisphere is an insulated compression arc-extinguishing hemisphere; multiple layers of arc-extinguishing channels arranged along the circumference are formed in the insulated compression arc-extinguishing hemisphere; and the bottom part of the insulated compression arc-extinguishing hemisphere is provided with an arc-striking electrode. The Coulomb-force-traction spherical compression jet airflow arc-extinguishing device and the sphere type arcing horn are simple in structure and can induce lightning to be conducted firstly, so that the power transmission metal line lightning shielding failure accident caused by lightninginterception failure can be reduced; and a thunder current is compressed, lengthened, thinned and ejected to extinguish arc, so that back striking probability caused by lightning stroke of a lightningconductor can be lowered.

Description

technical field [0001] The invention relates to a lightning protection and arc extinguishing device, in particular to a spherical compressed jet airflow arc extinguishing device and a spherical arc striking angle drawn by Coulomb force. Background technique [0002] At present, in order to protect the conductors of metal transmission lines from being struck by lightning, it is generally used to erect lightning conductors. my country's electric power industry standard DL / T620-1997 "Overvoltage Protection and Insulation Coordination of AC Electrical Installations" stipulates in Article 6.1.2: 110kV along Lightning protection lines should be erected along the entire line. In mountainous areas and areas with particularly strong lightning activities, it is advisable to erect lightning protection lines along the entire line. The structure of the lightning protection line is to install a bare steel strand on the top of the left and right transmission towers above the three-phase tra...
