Abstract

The invention discloses a vertical blowing Coulomb force compression lightning arc extinguishing ball and a double ball type arc angle. The vertical blowing Coulomb force compression lightning arc extinguishing ball includes an arc extinguishing ball and a lightning guiding ball; There are several layers of arc extinguishing channels, 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 directly touch Connected or connected through connectors; there is an air flow outlet channel at the junction of two adjacent U-shaped arc extinguishing tubes, and the air flow ejection channel extends to the outer surface of the arc extinguishing ball, that is, the outer surface of the arc extinguishing ball is set There is an air outlet; an arc striking electrode is respectively arranged on the top and bottom of the outer surface of the arc extinguishing ball. The invention has a simple and reliable structure, attracts lightning pilots, and reduces transmission line shielding accidents caused by lightning interception failures; the lightning current is compressed, elongated, thinned and ejected to extinguish the arc, reducing the probability of counterattack caused by lightning strikes on the lightning protection line.

Description

technical field [0001] The invention relates to a lightning protection and arc extinguishing device, in particular to a vertical blowing Coulomb force compression lightning arc extinguishing ball, that is, a double ball type arc striking angle. 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-phase transmissi...
