Problems solved by technology

At the same time, the large grounding pulse current that occurs at the moment of lightning strikes the instantaneous lightning potential at the grounding point when the grounding point is grounded through the metal building materials of the building (structure) itself or through the downconductor of the lightning rod and the common grounding grid of the main reinforcement (the grounding impedance cannot be zero). The sharp rise (thousands to tens of thousands of volts) will cause breakdown and damage to the electrical equipment connected to the common ground point due to the instantaneous high voltage

Abstract

The invention relates to a lightning-protection earthing device, in particular to a double-shielding lightning rod and an earthing device, in particular to a lightning-protection earthing device suitable for fields, such as communication, electric power or traffic and the like. The lightning-protection earthing device belongs to the technical field of lightning-protection earthing. The double-shielding lightning rod and earthing device comprises a lightning rod tube, one end part of the lighting rod tube is provided with an insulated post fixedly connected, and the insulated post is provided with a calabash ball provided with a conducted ball tip; the conducted ball tip is provided with an anti-lightning shielding cable of which one end is connected with the conducted ball tip, and the other end passes through the calabash ball and the insulated post to extend into the lightning rod tube; the anti-lightning shielding cable is distributed along the length of the lightning rod tube; and the other end of the anti-lightning shielding cable, which is correspondingly connected with the conducted ball tip, is connected with a grounding electrode. The earthing device is compact and simple in structure, has good anti-lightning effect, can effectively attenuate thunder and lightning electromagnetic pulse, is convenient to install and use and is safe and reliable.

Description

technical field [0001] The invention relates to a lightning protection and grounding device, especially a double-shielding lightning rod and grounding device, specifically a lightning protection and grounding device suitable for communication, electric power or transportation, and belongs to the technical field of lightning protection and grounding . Background technique [0002] The existing commonly used needle-shaped lightning rod is grounded through the lightning rod tip, rod and the metal building material of the building (structure) itself, or connected to the main steel reinforcement ground grid of the building (structure) through the lightning rod rod. Moreover, conventional grounding devices are used, and the materials are hot-dip galvanized steel rods, angle steel, copper rods or stainless steel rods, etc.; the disadvantages of the above-mentioned grounding devices are that they cannot increase the contact area with the soil and do not have instantaneous capacitan...
