The recent thunderstorms in recent months in Shenzhen have continued. The company's switchboards have been detonated. The performance of each salesperson is booming. Each customer says that their telephones, computers, and equipment in the computer room have been damaged. Here, the technical staff of Wuhan Leichuang Technology Development Co., Ltd. explained to everyone the lightning process.
1 Induction Ray, as the name implies, is a lightning strike due to the electromagnetic induction effect. Due to the development of power networks and electronic networks, the biggest natural threat to the devices in the network is induced lightning. In the natural world, the earth itself has a magnetic field. Due to the abrupt changes in geomagnetism, the formation of lightning, and the influence of underground magnetically susceptible minerals, electromagnetic fields in different areas will change, and the electric wires in electric power networks are good conductors of electric power. The iron towers for erecting electric wires are also good. The magnetic conductor in the abrupt electromagnetic field induces a high voltage due to the electromagnetic induction effect. This is the induction of thunder. Induced lightning damage to the power grid: Destruction of insulators, resulting in obstructed power transmission; affect the quality of power delivered; can also affect the power facilities in a wider range through the transmission of the power grid. Therefore, we must have a full understanding of the hazards of induced lightning and necessary preparations.
2. Regular telephones are generally equipped with lightning protection circuits to prevent the normal thunderstorms. However, for insurance reasons, we still need to strengthen mine protection measures. When laying cables for fixed telephones, it is generally necessary to consider the issue of lightning protection. If users modify the direction of the cables themselves, they must pay attention to lightning protection and reliable grounding. If necessary, install lightning protection equipment. If the user is in a thunderstorm-prone area and there are high requirements for lightning protection, consider installing a telephone lightning arrester. In normal circumstances, it is possible to wrap the phone cable into a large number of loops after entering the home, and then use transparent tape to wrap it up, which can provide a simple lightning protection function. If lightning strikes suddenly, for the sake of safety, it is also possible to pull out the telephone line of the fixed telephone, completely cut off the passage of the surge voltage, and protect the telephone.
3. If the subscriber line is in overhead, network switches, routers, etc. are the easiest to be struck by lightning. Our electronic equipment is generally struck by lightning. The main reason is that lightning wave damage equipment (5V will make routing , switch, network card hit), generally the power line in the lightning wave attenuation after the line will hardly cause damage to the equipment, so the lightning protection of electronic equipment should mainly be signal lightning protection switch and the appearance of the switch almost In the same way, the installation is quick and easy, and now it is used in a large area. It should be noted that the traces passing through the switch to the user's terminal are also important for lightning protection.
