Abstract

The invention discloses a compression recoil pipe structure capable of bearing high-strength impact, and belongs to the technical field of lightning protection and arc extinguishment. The structure comprises a ceramic pipe body, a lightning arresting device, an insulation fixing layer and a skirt hem. The lightning arresting device is embedded on the ceramic pipe body, the insulation fixing layer wraps the outer side of the ceramic pipe body and the lightning arresting device, and the skirt edge is arranged on the outer side of the insulation fixing layer. The stability of a recoil arc extinguishing structure is enhanced, the airtightness of the device is improved, gas leakage in the recoil process is avoided, all recoil energy is concentrated to act on an electric arc, and lightning stroke current is reduced more effectively.

Description

technical field [0001] The invention relates to the technical field of lightning protection and arc extinguishing, in particular to a compression recoil tube structure capable of withstanding high-strength impact. Background technique [0002] Lightning is one of the most common geophysical phenomena in nature. It has the characteristics of wide spatial and temporal distribution and strong randomness. The physical process mechanism of lightning discharge is complex and difficult to study. In recent years, with the rapid development of the power grid and the increase of strong convective weather, lightning faults have occurred frequently. At present, the risk of lightning damage in the power grid is mainly concentrated in the transmission line. Lightning is extremely harmful to the safe operation of transmission lines. The impact flashover caused by lightning strikes on transmission lines will cause flashover of line insulators, and then generate a large power frequency freew...
