We all know that street lights are an outdoor type of lighting, so there are many situations in the outdoor, such as lightning, wind and rain. Which precautions should the following Flood Light manufacturers take when encountering lightning? Just share the lightning protection system knowledge of the street lights.
According to the material of the street lamp itself, it is considered to be a combination of external lightning protection and internal lightning protection. Since the street light material is a conductor, it is equivalent to a lightning rod. The design must have a down conductor and a ground grid installed. These systems form an external lightning protection system.
After the external lightning protection system is completed, fires and personal safety accidents caused by direct lightning strikes of street lamps can be avoided. After external lightning protection, the internal lightning protection system protects the equipment by grounding and voltage protection.
The internal lightning protection system is designed to prevent inductive lightning and other forms of overvoltage intrusion, resulting in power supply damage. This is also not protected by an external lightning protection system. Therefore, both internal and external protection can complement and complement each other.
Due to the structure of the internal lightning protection system, many equipment (such as the enclosure, cables entering and leaving the protection zone, metal pipes, etc.) should be connected to the external lightning protection system, or an overvoltage protector equipotential bonding should be provided. And completely eliminate the destructive potential difference caused by lightning, signal lines, metal tubes, power lines and so on. An overvoltage protector must be used, equipotential bonding, and the equipotential bonding of the internal potential protection zone should be connected to each other. The interface of each part also needs equipotential bonding, and finally the other locations are connected to the main equipotential.
Finally, high quality protection equipment, lightning protection modules and surge protectors must be installed. The large pulse energy generated by lightning strikes in the circuit is released to the ground through the short-circuit line, thereby reducing the potential difference between the device interfaces, thereby protecting the device.
