For the protection of direct lightning strikes, install lightning rods on the support structure of the LED display (outdoor), indoor LED displays or LED displays with tall buildings next to them, do not need to consider installing lightning rods.


In response to the counterattack of the steel structure, connect the rigid structure to the shell of the ED display screen, do the equipotentiality, and do the grounding. The grounding resistance is generally required to be less than 10 ohms. If the resistance does not meet the requirements, additional labor will be required. ground grid. The lightning arrester should also be grounded.


For the lightning current induced on the power line, install a single-phase or three-phase power lightning protection device on the power line. The cross-sectional area of the link line of the phase line should not be less than 10mm square, and the cross-sectional area of the ground wire should not be less than 16mm square.


For the lightning current induced on the signal line, install a signal lightning arrester on the signal line. The signal arrester depends on the signal interface of the system. If it is a network cable, install the network signal arrester, and install the DB9 interface arrester for the serial interface. The cross-sectional area of the ground wire should not be less than 1.5mm square.

Regarding how to use the LED display screen reasonably in harsh conditions, LCF reminds you to do the following.


Regularly check the firmness of the joints. If there is any looseness, pay attention to timely adjustment, re-reinforcement or re-hoisting; according to the environmental conditions of the LED display, to avoid insect bites, place rodenticide if necessary; installation The LED display should avoid looking directly at the ultraviolet rays and avoid direct sunlight for a long time; the grounding socket must be installed correctly to avoid the wrong connection between the zero and the live wire. If you lose frequent power outages, double-check the power source.


Due to its excellent communication function, the LED display screen is used by the majority of businesses. I would like to remind all businesses that during the high thunderstorm period, please use the LED display screen reasonably.
