Abstract

The invention discloses a lightning protection device for a metal chimney of a boiler room. A lightning arrester fixing assembly is arranged and is in insulated connection with a smoke cap of the metal chimney, a downlead fixing assembly is arranged and is in insulated connection with a barrel body of the metal chimney, thus, physical and chemical damage to the metal chimney caused by high temperature in a welding mode can be avoided, electrochemical corrosion to the metal chimney possibly caused by contact of different metal materials with the metal chimney can be avoided, and therefore the service life of the metal chimney of the boiler room can be prolonged.

Description

technical field [0001] The invention relates to the heat pipe fixing support technology, in particular to a lightning protection device for a metal chimney in a boiler room. By setting a lightning receptor fixing component and realizing an insulating connection between the lightning receptor fixing component and the metal chimney smoke cap, by setting the down conductor The wire fixing component and the insulating connection between the down conductor fixing component and the metal chimney body can not only avoid the physical and chemical damage to the metal chimney due to high temperature caused by welding, but also avoid the possible damage to the metal chimney due to contact between different metal materials. The electrochemical corrosion brought by it is beneficial to prolong the service life of the metal chimney in the boiler room. Background technique [0002] Metal chimneys in boiler rooms are vulnerable to lightning strikes during use. In order to prevent or reduce ...
