Abstract

The invention discloses a horizontal and vertical blowing Coulomb force compression lightning arc extinguishing ball and a double-ball type arc angle. There are several layers of arc extinguishing channels inside the main body, and several U-shaped arc extinguishing tubes are placed in each layer of arc extinguishing channels, and the ends of two adjacent U-shaped arc extinguishing tubes in the same layer of arc extinguishing channels pass through The three-way pipes are connected; there is an air jet channel at the junction of the U-shaped arc extinguishing tube and the three-way pipe, and the air jet channel extends to the outer surface of the arc extinguishing ball, that is, the outer surface of the arc extinguishing ball is provided with an air jet. Outlet; there are respectively an arc striking electrode on the top and bottom of the outer surface of the arc extinguishing ball. The invention has a simple and reliable structure, attracts the lightning pilot, and reduces the transmission line shielding accident caused by the failure of lightning interception; the combination of horizontal and vertical blowing compresses, elongates, thins and sprays the lightning current, extinguishes the arc, and reduces the lightning protection caused by lightning. The counterattack probability caused by the line.

Description

technical field [0001] The invention relates to a lightning protection and arc extinguishing device, in particular to a double-ball type arc arcing angle blown horizontally and vertically by Coulomb force compression induced lightning arc extinguishing ball. Background technique [0002] At present, in order to protect the conductors of the transmission line from being struck by lightning, it is generally used to erect lightning conductors. Article 6.1.2 of my country's electric power industry standard DL / T620-1997 "Overvoltage Protection and Insulation Coordination of AC Electrical Installations" stipulates: 110kV along the entire line Erection of lightning protection lines. 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-ph...
