How To Avoid Lightning On The LED Display

In summer, summer thunderstorm weather, bad weather is also a test of LED display, LED display electronic components are highly integrated, its sensitivity to interference is getting higher and higher, lightning can endanger the display screen in various ways, such as being hit, lightning current will cause mechanical, electrical, thermal damage, thereby causing serious damage to the LED display. It can even start a fire. Therefore, lightning protection for LED displays is essential.

Lightning protection measures for LED display:

1. For the protection of direct lightning, install lightning rods on the support structure of LED display (outdoor), indoor LED display screens or LED displays with tall buildings next to them, you can install lightning rods without consideration.

2. For the counterattack of the steel structure, the rigid structure is related to; The shell of the ED display screen is connected, do a good job of equipotential, and do a good job of grounding, the grounding resistance is generally required to be less than 10 ohms, if the resistance value does not meet the requirements, it is necessary to do additional artificial grounding network. The lightning protector should also be grounded.

3. For the lightning current induced on the power line, a single-phase or three-phase power supply lightning protector is installed on the power line. The cross-sectional area of the link line of the phase line shall not be less than 10mm square, and the cross-sectional area of the connecting ground wire shall not be less than 16mm square.

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

There are several suggestions on how to use LED displays reasonably under harsh conditions:

First of all, it is necessary to regularly check the firmness of the hook joint, if there is looseness, pay attention to timely adjustment, re-reinforcement or re-hoisting. 

Secondly, according to the environmental conditions of the LED display, it is necessary to avoid insect bites and place rodenticides if necessary.

Again, when installing the LED display, avoid direct ultraviolet rays and avoid direct sunlight for a long time. The grounding socket must be installed correctly to avoid zero and live wire handover errors. If power goes out frequently, double-check the power supply.

LED display screen because of its excellent communication function is used by the majority of businesses, here to remind all businesses, thunderstorm high incidence period, please use LED display reasonably.
