In today’s society, there is a certain shortage of electricity. Solar street lights do not generate any electricity, making them environmentally friendly. For users, utilizing solar street lights can significantly reduce operational costs. This advantage has led to the rapid development of solar street lights. However, during the summer, thunderstorms occur frequently. So how can we ensure proper lightning protection for solar street lights? Let’s take a look.
Lightning protection measures for solar street lights:
1. Grounding
This is very important. The pole body can be used as a discharge path, and the grounding network should be determined according to the geological soil conditions, with a grounding resistance of 10 ohms.
2. Circuit
Install dedicated photovoltaic DC lightning arresters. The design of arresters primarily depends on the power supply voltage. During thunderstorms, the circuit of solar street lights may experience a peak voltage or peak current due to static or electromagnetic induction, which can affect and damage the solar street lights. Therefore, it is essential to choose appropriate LED-specific lightning arresters to protect against surge overvoltages in the power lines, to prevent widespread damage to solar street lights in the same area due to lightning strikes.
3. Direct lightning protection
Direct lightning strikes occur when lightning hits an object directly. Using the lamp pole as a lightning rod is effective. Since there is a significant potential gradient from the lightning rod to the grounding device, to balance the potential and reduce the gradient, a closed circuit can form a horizontal lightning protection zone, effectively preventing side-strike lightning.
The above measures on how to effectively protect solar street lights from lightning have been shared here. I hope this article is helpful to everyone. If there are any unclear points, please leave a message, and we will respond as soon as possible.
