Abstract

The invention discloses a distributed coulomb force on both sides of the longitudinal direction to compress the lightning-inducing arc extinguishing ball. Inside the main body of the arc extinguishing hemisphere, there is an arc extinguishing path composed of several sections of arc extinguishing channels, and an arc extinguishing tube is placed in each section of the arc extinguishing channel, and the ends of two adjacent arc extinguishing tubes are connected; An airflow ejection channel is provided at the junction of two adjacent arc extinguishing channels, and the airflow ejection channel extends to the outer surface of the arc extinguishing hemisphere; an arc starting electrode is arranged on the top of the arc extinguishing hemisphere; In the path, the head end of the first arc extinguishing tube is connected with the arc striking electrode, and the end of the last arc extinguishing tube is connected with the lightning 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 lightning arc extinguishing ball compressed by distributed Coulomb force on both longitudinal sides. 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 transmission wire. However, due t...
