Two major misunderstandings of lightning protection measures for wireless transmission equipment
In general, most wireless transmission equipment is installed in an outdoor environment, and often can be exposed to various situations, such as wind, rain, snow, etc., but for wireless transmission equipment. It is not a big problem. However, once a certain situation is encountered, the equipment can be scrapped, that is, lightning strikes.
The rainy season in the south comes earlier, so it is necessary to do lightning protection measures this morning. Many users do not consider lightning protection when purchasing or installing wireless transmission equipment, or look at this problem lightly, but when they really encounter problems, they will regret that they did not do lightning protection. Therefore, the correct understanding of the importance of lightning protection measures is particularly important for the protection of wireless devices and the safety of the general public.
When it comes to lightning protection measures, many people have misunderstandings, and the following two typical mistakes are particularly prominent:
First, improper grounding; many people think that using multi-point grounding can be more secure, but in fact, multi-point grounding is only suitable for strong electricity. In monitoring weak current systems, single-point grounding can protect products. If multi-point grounding is adopted in a weak system environment, it is easy to cause the "grid ground potential" to enter the equipment system through the ground loop, forming a voltage "surge", while the weak current system has a low withstand voltage, and the voltage "surge" is weak. In the system, the pressure difference is too large, which damages the internal circuit of the system.
Second, the role of the wrong cognitive lightning rod. Many people think that installing a lightning rod on the bracket of a fixed device can successfully "lightning", but this method is wrong. In the outdoor pole camera, the lightning protection rod should be set up with an independent lightning rod. Moreover, the distance between the pole and the independent lightning rod should be greater than 4.5 meters. In addition, it is better to use insulating materials (such as cement or wood or plastic). Conducive to insulation. Therefore, installing a lightning rod on the pole is not a â€œlightning protectionâ€ but a â€œlightningâ€.
It is necessary to do lightning protection measures outdoors. Only when lightning protection is done, we can guarantee the normal operation of the equipment.
