When night falls, the street lights of our city will light up. Street lights in every city are installed outdoors. In the face of thunderstorms, lightning strikes are a great threat to street lights. When encountering strong lightning current, it may cause fire or casualties. How can Shandong solar street lamps avoid thunder and lightning? Do you need to install lightning protection equipment?

Shandong Qihang Electrical Appliance Co., Ltd. provides you with several effective methods to prevent lightning damage to street lights: considering that street lights are conductors, one method is the combination of external lightning protection and internal lightning protection. As the material of street lamp is conductor, it is equivalent to lightning rod, and downlead and grounding grid need to be installed in the design. These systems constitute the external lightning protection system. After the completion of the external lightning protection system, the fire and personal safety accidents caused by the direct lightning stroke of the street lamp can be avoided. After the completion of external lightning protection, the internal lightning protection system can protect the equipment by grounding and setting voltage protection. The internal lightning protection system is ready to prevent induced lightning and other forms of overvoltage intrusion, which may damage the power supply. This is also beyond the protection of external lightning protection system. Therefore, the built-in internal protection and external protection can complement each other.

When building the internal lightning protection system, it is necessary to connect many components (such as shells, cables entering and leaving the protected area, metal pipes, etc.) to the external lightning protection system, or provide overvoltage protectors for equipotential connection. And eliminate destructive potential difference caused by lightning, signal line, metal tube, power line, etc. An overvoltage protector is required for equipotential bonding. The equipotential connection of each internal protection zone needs to be connected with each other, and each local interface should also have local equipotential connection at each position, and then each position needs to be connected to the main equipotential position. After that, high-quality protective equipment, lightning protection module and power lightning protection device need to be installed. The huge pulse energy generated by lightning stroke in the circuit is released to the ground through a short route, thus reducing the potential difference between equipment interfaces and protecting the equipment.
