Summer is accompanied by hot weather, thunderstorm and long rainy season. Typhoon has a great impact on coastal cities. Large areas of precipitation put forward higher protection requirements for outdoor LED full color screens to prevent rain, thunder and wind.
1. Wind resistance and earthquake resistance
With the wide application of outdoor LED large screen advertising, the installation forms of LED display screen are more and more diversified, including wall mounted installation, inlaid installation, hoisting, roof installation, column installation, etc. In order to prevent LED display equipment from falling, there are strict requirements for the selection of load-bearing steel structure steel for wind load and seismic performance, especially for roof installation and column installation
2. Lightning protection measures
In order to ensure good grounding, all metal boxes and back covers of LED large screen equipment have separate grounding terminals. The terminals are connected with waterproof fasteners and ratchet pads. The grounding is reliable. The large screen equipment adopts the common ground wire structure, which is a way of "three grounds" (equipment working grounding, power grounding, lightning protection grounding). The protected power supply and signal system lightning strike and surge voltage damage the equipment
3. Internal and external leakage prevention
The mask and cabinet are made of insulating materials. The insulation material resistance is greater than 10 megohms, and the leakage current is less than 1.8 MA. The product can still withstand 50 hz under hot weather conditions according to our department's test. The insulation strength shall be 1500W test voltage breakdown for 1 minute. The circuit board will be protected by three proofing paint, and the quality of large LED display screen shall be higher than IP65 waterproof grade in the international protection system. In this way, leakage can be guaranteed from materials to waterproof performance
4. Control humidity Outdoor humidity in large screen
When the full-color screen with humidity is powered on, it will lead to corrosion of full-color screen components, thus causing damage; So keep in the environment of full-color LED large screen, and do not let anything with humidity characteristics enter your LED large screen.
