Anti-thunder lightning-protection device used for pipeline joints

Abstract

The invention discloses an anti-thunder lightning-protection device used for pipeline joints. The anti-thunder lightning-protection device comprises pipelines, wherein matched cylindrical sleeves sleeve the peripheries of the pipelines; three equally spaced and symmetrically distributed hinged blocks are embedded into each cylindrical sleeve; a first vertical rod piece and a second vertical rod piece in symmetrical distribution are fixedly arranged on the two hinged blocks positioned at the upper part respectively; a first lightning-protection ring is fixedly arranged on each first vertical rod piece; a second lightning-protection ring is fixedly arranged on each second vertical rod piece; and the first lightning-protection rings and the second lightning-protection rings are symmetricallyarranged. The device is applied to the technical field of anti-thunder lightning-protection design of pipeline connecting pieces or circuit connecting pieces, uniformly distributed inductive charge layers are formed around the first lightning-protection rings and the second lightning-protection rings, and an electric field environment with relatively uniform distribution is formed by the inductivecharge layers and thundercloud, so that the probability that pipelines or signal circuits suffer from lightning strokes is obviously reduced.

Description

technical field [0001] The invention relates to a lightning protection device for pipeline joints, belonging to the technical field of pipeline lightning protection design. Background technique [0002] The traditional lightning rod is installed at the highest point of the lightning protection object. When lightning occurs, this highest point and the thundercloud form an extremely unevenly distributed electric field environment, which makes the air between the thundercloud and the lightning rod easy to be broken down, and the lightning current is extremely high. It is easy to discharge the lightning energy to the earth through the lightning rod. This lightning protection method that discharges the lightning energy through the lightning rod itself is more likely to cause a direct lightning strike. Therefore, the traditional lightning rod leads the lightning to itself and the ground discharges the lightning energy. The lightning protection of valves, pipeline connectors, signa...

This lightning protection method that discharges the lightning energy through the lightning rod itself is more likely to cause a direct lightning strike. Therefore, the traditional lightning rod leads the lightning to itself and the ground discharges the lightning energy. Lightning protection for valves, pipeline connectors, signal lines and signal connectors provides safety protection
