Method for installing pre-discharge lightening rod

Abstract

The invention discloses a method for installing a pre-discharge lightening rod. The method is characterized by including the following steps: a. assembling every part of a pre-discharge lightening rod, securing the pre-discharge lightening rod as a whole to a pedestal by tightening with bolts or welding; b. upon installing the pre-discharge lightening rod, conducting reliable welding or thermit welding on the pre-discharge lightening rod and a downlead; c. installing a ground resistance test case below the pre-discharge lightening rod, providing a lightening counter inside the ground resistance test box; d. fusing a ground rod of the pre-discharge lightening rod with a ground wire with a fire clay powder; and e. after the installation of the pre-discharge lightening rod, applying an anti-rust paint on the connecting place of every part of the pre-discharge lightening rod or the metal surfaces of every part, and conducting anti-rust processing. According to the invention, the method is advantaged over traditional lightening rod and thunder-protection systems by increased protection radius, and by providing more protection, having high safety, and strong protection for factor devices and workers.

Description

technical field [0001] The invention relates to a method for installing a lightning rod, in particular to a method for installing a pre-discharge lightning rod. Background technique [0002] Pre-discharge lightning rod, also known as early discharge lightning rod, is a kind of lightning current that is quickly transmitted to the earth in advance, so as to ensure the safety of buildings and personnel. [0003] The pre-discharge lightning rod has been widely used in Europe and has been standardized (NFC17-102). The pre-discharge lightning rod is based on the traditional lightning rod discharge principle and introduces the basic characteristics of the pre-discharge lightning rod, which is "promoting ionization". This kind of lightning rod can realize early discharge without waiting for the lightning field intensity to increase to a certain extent, and the protection radius is larger, which reduces the lightning current pulse intensity when the lightning rod receives lightning e...

AI Technical Summary

Problems solved by technology

If the new construction of the steel slag stabilization treatment line of Formosa Ha Tinh Iron and Steel Plant in Vietnam adopts the traditional common lightning rod lightning protection system, the protection radius will be small, the protection safety will be low, and the safety of equipment and personnel in the plant will be poor.

[0008] Therefore there is above-mentioned inconvenience and problem in known common lightning rod
