Protection against the lightning strike in cement plant
Yun Hong · 2006
There usually has hidden troubles because of improper treatment to lighting-trike-proof design.Besides normal lighting strike protection,inner protection to lighting electric wave invasion and electromagnetism impulse induction also should be considered.When we design a cement plant,we should plan the outer and the inner protection as a whole according to related present criterions and aming to the architectural characteristic of the plant.And for the outer protection,using mental components on the roof as lighting electrode,using main reinforcing steel bar in structure pole as down-lead and using meshwork of base reinforcing steel bar as earthing electrode;for inner protection,applying equivoltage connection system and sharing one earthing system or setting excessive voltage protection system and so on.All the practice shows,the measures can protect the architecture and equipment of the cement plant from damage of lighting strike.
