In the outdoor placement of high-pole lights, the use of the process will inevitably encounter a variety of extreme weather, today for everyone to share how to prevent lightning strikes outdoor high-pole lights?
1, the combination of external lightning protection and internal lightning protection: at present, the external conductor material of the conventional street lamp pole is the same as the lightning rod itself. In the design, it is necessary to set down the lead line and ground grid to form an external lightning protection system. The system prevents life safety incidents caused by street light fires and direct lightning strikes. The so-called internal lightning protection system refers to the internal grounding of the street light and the maintenance of the facility in the form of maintaining voltage.
2. Lightning equipotential connection: In order to completely solve the destructive potential difference caused by lightning strikes, it is necessary to connect the power cord, signal cable, metal pipe, etc. to the overvoltage protector, and perform local equipotential connection at the interface of each internal protection area, and connect the local equipotential connection parts to each other, and connect with the total equipotential.
3, mine-proof area setting: at present, in addition to power supply facilities, but also set up a number of communication facilities, control the switch and brightness of the street lamp. These facilities and power supplies must be equipped with mine-proof areas, and the maintenance areas are directly shielded with enclosures.
