How to prevent the led high bay light from being damaged by lightning?
As we all know, lightning has always been a natural enemy of electrical equipment (the same is true for integrated light source led high bay lights), and even in the lightning season, the construction efficiency of the construction team will be effectively reduced. However, with the continuous upgrading of various lightning protection techniques and methods, Shandong led high bay lights can also effectively prevent lightning. But how to prevent the led high bay light from being damaged by lightning?
1. Set up a lightning protection zone: This is a more direct and early general method to prevent lightning damage. At present, for LED high bay lights, in addition to power supply equipment, some communication equipment will be set to control the switch and brightness of street lights. These Both the equipment and the power supply need to be placed in the lightning protection area, and the protection area is directly shielded by the casing. Since the electromagnetic field here is much weaker, it is also much less destructive to lightning.
2. Lightning protection equipotential connection: In order to completely eliminate the damage caused by lightning, general electrical appliances must be equipped with an overvoltage protector for equipotential connection, and the interface of each inner protection zone of the led high bay light should also be connected locally. That is to say, each local equipotential junction of the led high bay light should be connected to each other, and then connected to the main equipotential point.
3. Combination of external lightning protection and internal lightning protection: Now the general led high bay light is made of conductor materials, which itself is equivalent to a lightning rod. The internal lightning protection system refers to the protection of the equipment by means of grounding and setting voltage protection inside the led high bay light. The system can prevent the intrusion of induced lightning and other forms of overvoltage, which can cause damage to the power supply, which cannot be guaranteed by external lightning protection systems. The two complement each other and complement each other.
The above three points are the ways to prevent the LED high bay light from being damaged by lightning and cause abnormal lighting. In addition to the above three points, there is also a high-quality protection device - using a lightning protection module and an overvoltage protection module, the lightning protection device can connect the protected system to the equipotential system in a short period of time, so that the ports of the equipment, etc. potential. At the same time, the huge pulse energy generated by lightning strikes in the circuit is released to the ground through the short-circuit line, reducing the potential difference of each interface end of the equipment, thereby protecting the equipment.
