Most of the wireless bridges are installed in remote outdoor areas. In order to ensure better transmission during the installation process, the equipment is usually elevated or installed at the commanding heights of the environment. So, in the face of thunderstorms that are often encountered in summer, we have to consider the lightning protection of wireless bridges. For professional equipment manufacturers, how do you do the lightning protection measures for wireless bridges? Let's take a look at them. 1, pre-installation Before the installation in the early stage, the installation location should be selected. According to the general construction requirements, buildings with a height of more than 20 meters or heavy machinery, tower cranes, etc. need to be equipped with lightning rods. The lightning receptors are generally φ16mm round steel with a length of 1~2 meters. The top should be made into a cone tip. The lightning receptor needs to be hot-dip galvanized. When we install the equipment on these objects, install the equipment within 45° of the effective protection angle of the lightning rod. Because the effective protection range of the lightning rod is below 45° of the top of the lightning rod, it can effectively avoid damage caused by direct lightning. 2, POE module lightning protection The wireless bridge utilizes the POE power supply technology, and the twisted pair transmits data and power at the same time. We recommend professional POE lightning protection technology. The POE lightning protection device can effectively protect the data port and power port of the device from being damaged by surge, inductive lightning and static electricity. However, the POE lightning protection module must be well grounded and the grounding resistance must be less than 4 ohms. If the requirements are not met, the grounding electrode should be added. If the conditions are not good, the electrolyte should be added and/or the soil should be replaced. Xiaobian uses the experience of on-site construction for customers. Although customers have POE lightning protection measures for equipment, they cannot achieve good lightning protection during the thunderstorm season, which causes equipment damage. The reason is that although the POE lightning protection equipment is installed, all the POE modules of the damaged equipment are not grounded. The equipment that has been effectively grounded is no different. Therefore, the POE lightning protection module cannot be effectively grounded or grounded at all. Then lightning protection will not play any role. Finally, Xiaobian needs to emphasize that the lightning protection measures for wireless bridges are very important. Perhaps they have learned the above knowledge. Customers are still worried that they can't do lightning protection of equipment. It doesn't matter. Xiaobian teaches you a trick, customers only need to find a professional. The equipment supplier, the only thing left is to wait for the acceptance of the project effect.
