Is it important to monitor the lightning rod on the column of city surveillance cameras?
Street lamp is a strong electricity, simple structure, is not vulnerable to lightning damage, monitoring equipment is electronic equipment, precision electronic circuit is vulnerable to lightning surge damage, so the lightning protection requirements of monitoring equipment is higher than the street lamp.
The lightning rod (lightning arrester) at the top of the monitoring rod can be used to pass the lightning through the metal pole, so as to avoid the damage of the direct lightning to the monitoring equipment.The lightning rod is aimed at striking lightning.Lightning arrester is to prevent the line from the induction of lightning surge, that is, induced lightning.The functions of the two are different, combined with the maximum extent of the purpose of lightning protection.
Ha ha, meaning littleCan not say no senseBut it doesn't really work. There's not much lightning in the city
