Description

Technical Field

[0001] The utility model relates to the technical field of anti-static devices, in particular to a high and medium frequency lightning current shunt. Background Art

[0002] More and more large vertical oil tanks used in oil depots and chemical plants adopt floating roof designs. The floating roof of the oil tank is a floating roof cover floating on the surface of the stored liquid, which floats up and down with the input and output of the stored liquid. There is an annular space between the floating roof and the tank wall, and this annular space has a secondary seal. The secondary seal is a set of devices added on the basis of the primary seal, which isolates the liquid in the tank from the outside while the top cover floats up and down, thus greatly reducing the evaporation loss of the stored liquid during storage. However, the secondary seal of the floating roof oil tank is generally made of insulating materials such as rubber, which insulates the metal floating roof from the outer wall of the oil tank and makes the floating roof unable to be grounded. This inevitably brings potential safety hazards because a large amount of static electricity will be generated during the flow and friction of oil products during storage and transportation, and it is easy to form static discharge with an isolated conductor that is not effectively grounded.

[0003] At present, the lightning protection and anti-static connection of floating roof oil tanks mostly adopts a flake-type conductive connection at the secondary seal to conduct discharge.
