Does the LED street light power supply have built-in lightning arrester?
1. First of all, it is impossible for the arrester to be made into full voltage, and the SPD can only be made into single voltage, which is caused by the components and cannot be changed;
When there is a direct lightning strike on the lamp head, it is attracted by the conductive locking bolt, and the lightning current is introduced into the lamp pole. The flange at the bottom of the pole is corroded, and there is no discharge channel for the current. At this time, because the construction party has reliably connected the PE line of the mains to the pole body, the lightning current enters the power PE line and runs around, and the PE potential of the entire system is raised. Tens of thousands + volts.
2. Secondly, the lightning arrester must have the necessary thermal tripping device, which is not something that a current fuse can do;
The lightning current discharge channel of the PE line is not wide, and the lightning current "spills" laterally: look for fragile click-through. As a result, the LED lamp beads in the LED lamp head are broken down, and the LED power supply is subjected to the lightning current energy from the rear stage.
3. After that, a complete thermal design must be done in the system, specially designed for the TOV experiment in IEC61643 and UL1449.
At the same time, the longitudinally discharged lightning current flows to various electronic terminal equipment of the toll station through the PE line of the mains, and keeps breaking down and gushing out, and finally finds the copper PE busbar connected to the ground network in the distribution box of the area. After the lightning surge breaks through the air switch and fuse fuse in the distribution box, it rushes into the ground through the PE busbar.
In the LED lighting industry, lightning protection is simple, and a few components are just a product. In fact, it is not. Botai Lighting said that lightning protection is to solve 0.001% of the risk for customers. When that 0.001% occurs, the product should never fall off the chain at a critical moment, especially the LED street lamp shell. Do a good job in product quality testing , truly risk-averse.
