Lightning protection measures for solar street lights

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 voltage capacity is lower than ordinary street lights.

Because the circuit of the LED street lamp will pass through by electrostatic induction or electromagnetic induction during a lightning weather, a surge voltage or a surge current will occur, which will affect and crush the LED street lamp equipment.

u003cbru003e 1. Solar street light grounding: This is the most important thing. You can use a pole to drain the fluid. The grounding network is determined according to the geological soil, and the grounding resistance is less than 10 ohms. Therefore, it is necessary to choose a suitable LED special lightning protection device to protect the power line from surge overvoltage, so as 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.
