Coulomb force traction recoil intermittent arc interrupting method and lightning rod

Abstract

The invention discloses a coulomb force traction recoil intermittent arc interruption method and a lightning rod, and belongs to the field of lightning protection and arc extinguishing. The lightningrod comprises a hollow recoil pipe, the bottom of the recoil pipe is arranged on an electrode plate, a lightning receiving electrode and a tip electrode are arranged at the bottom end of the interiorof the recoil pipe, and the tip electrode is arranged on the lightning receiving electrode; and the lightning receiving electrode is in contact with the electrode plate. The arc path is strictly controlled. The metal electrode plate forms huge inductive charges and generates a large number of inductive charges at the tip electrode, and control over a lightning flashover path is achieved from the two dimensions of coulomb force traction and ascending guide. arc extinguishing is synchronous. The electric arc is blocked by utilizing recoil energy while the electric arc receives lightning.

Description

technical field [0001] The invention relates to the field of lightning protection and arc extinguishing, in particular to a Coulomb force traction recoil intermittent interrupting arc method and a lightning rod. Background technique [0002] Lightning is a gas discharge phenomenon in nature. During the lightning discharge process, it presents electromagnetic effects, thermal effects and mechanical effects, which are very harmful to buildings and electrical equipment. Therefore, we need to set up protective devices to avoid or reduce less dangerous. We need to set up protective devices to avoid or reduce the damage caused by lightning. We use lightning rods to protect buildings, tall trees, etc. from being struck by lightning. The function of the lightning rod is to attract lightning to strike itself, and quickly discharge the lightning current into the earth through the grounding device. But the lightning rod still has some disadvantages. [0003] 1. The discharge process...

AI Technical Summary

Problems solved by technology

However, when a huge lightning current quickly discharges to the ground, the lightning current will generate a huge instantaneous electromagnetic field. This huge electromagnetic field will affect the electronic equipment, communication equipment, and power system lines in this magnetic field. These equipment may generate The extra induced current will cause misoperation of the device if it is light, and damage the equipment if it is heavy

[0005] 2. The degree of reduction of lightning overvoltage is not enough:

[0006] When an ordinary lightning rod is used to protect an object, when a strong lightning current quickly flows through the lightning rod, a high impulse voltage will be generated. The degree is not enough, the equipment is still not fully protected by the lightning rod
