Abstract

The invention discloses a single-recoil counter-blowing arc extinguishing device, and belongs to the technical field of lightning protection and arc extinguishing. The device comprises an insulator string, an upper end fixing device, a lower end fixing device, an upper end recoil device and a lower end recoil device, and the upper end fixing device and the lower end fixing device are arranged at the two ends of the insulator string in parallel. According to the invention, the bidirectional dynamic insulation cooperation capability is realized, the insulation strength and the lightning resistance level of an original line are not reduced during normal work, the insulation cooperation distance of the recoil pipe is automatically reduced and the recoil pipe is preferentially broken down under a lightning stroke condition, the insulator flashover is avoided, and the double-recoil impact arc cutoff capability is realized; and the lightning stroke current intensity is reduced through the recoil effect, the ionization intensity of the impact arc is weakened, the vulnerability and the shortness of the arc are improved, and the cost performance of lightning protection is increased. The device can process in time before malignant mutation occurs so that the lightning arrester is prevented from being damaged by lightning stroke, the maintenance cost is reduced, and the line protection degree is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a single recoil pair blown arc extinguishing device. Background technique [0002] Lightning disasters are one of the most serious meteorological disasters. UNESCO has listed lightning strikes as the third most destructive natural disaster in the natural world. It will endanger the lives of humans and animals and destroy various buildings. The security of the national economy and people's lives poses a serious threat. [0003] Lightning is extremely harmful to the safe operation of transmission lines, often causing insulator flashover accidents. The impact flashover caused by lightning strike on the transmission line will cause the flashover of the line insulators, and then generate a large power frequency continuous current, damage the insulator strings and fittings, and may lead to burnt insulator strings and overhead wire disconnection accidents in severe cases. Usually ...
