How is 20W solar street light harmed by lightning? In thunderstorm weather, the circuit of the solar street light will pass through a sudden peak voltage or current from electrostatic induction or electromagnetic induction, which will affect and crush the solar street light equipment.

The lightning protection work of a 20W solar street light is different from that of ordinary street lights. The main reason is that the response speed of solar street light is much faster than that of ordinary street lights, and the withstand voltage capacity of solar street light is naturally smaller than that of ordinary street lights. In open areas, high mountains and areas where thunderstorms often occur, lightning protection methods are particularly important. Therefore, the lightning protection design of solar street lights can take preventive measures from three aspects:

1. Anti direct lightning: to prevent direct lightning from hitting the pole of a solar street light, it is necessary to make the pole into a lightning receiver, so that when lightning strikes, it can direct lightning to itself and undertake direct lightning discharge.

2. Grounding: This is the most common and effective method. To prevent electric shock or protect the safety of the equipment, the pole itself is used as the discharge fluid, and the earth is used as the current loop grounding wire. Generally, the grounding grid should be determined according to the local geological soil. The resistance of the grounding should be less than 10 ohms. Besides, the circuit system of the solar street light should also be selected at the appropriate position Earthing.

3. Circuit: install special solar lightning arrester. The lightning arrester is mainly designed according to the power supply voltage of the solar street light. In lightning weather, the circuit of the solar street light will generate a spike voltage or current through electrostatic induction or electromagnetic induction, which will affect the LED solar street light equipment. The special lightning arrester for solar street lights can protect the surge voltage of the power line and avoid the lightning damage of large-area solar street lights in the same area.
