Lightning protection measures for solar street lights
December 15, 2020
The lightning protection work of
solar street lights is different from that of ordinary street lights. The main reason is that the response speed of LED is faster than ordinary street lights, and the ability to withstand voltage is smaller than ordinary street lights.
The lightning protection device is mainly designed according to the power supply voltage. Because the circuit of the LED street lamp will pass through by electrostatic induction or electromagnetic induction, a surge voltage or surge current will occur during lightning weather, thereby affecting and crushing the LED street lamp equipment.
In open areas, mountains, and areas where thunderstorms often occur, lightning protection methods are particularly important. How to protect solar street lights from lightning is the most troublesome and technically challenging issue for many solar street light manufacturers. So how does Longine Lighting solve it?
Solar street lamp grounding: This is the most important thing. Just use a pole to drain the fluid. The ground network is determined according to the geological soil, and the grounding resistance is less than 10 ohms. Therefore, it is necessary to select a suitable LED special lightning protection device to protect the power line from surge overvoltage to avoid the phenomenon of large-area LED street lamp lightning damage in the same area.
2. Circuit: Install a special photovoltaic DC lightning protection device.
3. Anti-direct lightning strike: just use pole as air-termination device.
