http://www.pump-industry.crotection method is used as the basis, and in-depth in all aspects, the monitoring system can be proightning protection devices are also relatively high, but everyone can use the above The lightning pthe lightning protection technology is also very complex. The performance requirements for various ll monitoring system lightning protection needs to be comprehensively considered in all aspects, and e controlled within 4 ohm. <br><br> The above are just some basic lightning protection measures. Reag resistance is, the worse the lightning protection effect is, and the grounding resistance should bention to the fact that the resistance of the grounding device is minimized. The larger the groundins, so that the security of the monitoring center can be fully protected. Finally, we need to pay attonitoring center are preferably protected against lightning by lightning protection grounding devicen devices must be installed to prevent direct lightning strikes. All the electronic devices in the mt the access point of the signal line to prevent inductive lightning, and ground lightning protectioe monitoring center through the signal line. Therefore, the lightning arrester should be installed a monitoring equipment on it. Top floor. The outdoor monitoring facilities are mainly connected to th note that we should not place monitoring equipment next to the windows, and it is best not to placeneed to consider adding additional lightning protection devices to the buildings. It is important to attacks. Buildings are equipped with lightning rods, lightning protection nets, etc., so we do not itoring equipment, only comprehensive lightning protection methods can effectively prevent lightningnce the monitoring center involves lightning protection of buildings and lightning protection of monon of the monitoring center is the core of the entire monitoring system for lightning protection. Si Limits limit the harm caused by lightning to the monitoring system. <br><br> The lightning protectilightning protection device at the support point of the support signal line in order to maximize thel a lightning arrester at the front end of the signal line, and at the same time install a grounded htning strikes, and it is also vulnerable to induced lightning attacks. Therefore, we need to instalo effectively prevent lightning attacks. The signal line in the air is most vulnerable to direct lig, and install a grounding lightning protection device at the front end of the metal pipe. In order tion. It is also necessary to install the signal line into a metal pipe with a relatively large spacelay a certain degree of lightning protection effect, but it is not 100% capable of lightning protectn two ways, directly in the air and buried in the ground. The signal line buried in the ground can ph the signal line of the transmission system. The signal line of the transmission system is set up itection and are not suitable here. The network camera is connected with the monitoring center througin front of us. These lightning protection devices are all oriented to a wide range of lightning proill be used to direct lightning into the earth. We also mentioned some lightning protection devices t is best to install lightning rods 3 to 4 meters around the network cameras. Lightning conductors wrect lightning strikes. To prevent outdoor distribution of network cameras from lightning strikes, ibasically not attacked by direct lightning. Outdoor distributed network cameras may be subject to dion modes, outdoor distribution and indoor distribution. The indoor distribution network cameras are y that needs protection. <br><br> The network cameras of the surveillance system have two distributition uses a variety of lightning protection devices to prevent lightning attacks on a single facilitlightning protection mainly uses arresters to prevent lightning attacks. Integrated lightning protec, lightning protection lines, lightning protection strips, and lightning protection nets. Induction otection device to prevent lightning. Anti-lightning lightning devices mainly include lightning rodsion lightning protection is a single lightning protection method. They all use a single lightning prt lightning, inductive lightning and integrated lightning protection. Anti-lightning and anti-inductays to prevent thunder and lightning from attacking the network monitoring system, and prevent direced to be protected. <br><br> <strong>Prevention of lightning strikes <br></strong> There are three wThese two types of lightning attacks have also become two aspects of the surveillance system that ned lightning is not directly damaged by direct lightning, but the chance of occurrence is very high. ite charge to the thunder cloud. This is called electrostatic induction. The damage caused by inducetion. When a thunder cloud appears over the transmission line, the transmission line senses an opposelectromagnetic field will induce a large electromotive force, which is called electromagnetic inducthe connection line under the lightning rod. The monitoring device and the transmission line in the lightning hits the lightning rod, a momentary strong electromagnetic field will be generated around econd lightning. It is divided into electromagnetic induction and electrostatic induction. When the serious, but the probability of occurrence is relatively small. Inductive lightning is called the srikes directly on the network camera. The damage caused by this type of lightning strike is the mosts of attacks, direct lightning and induced lightning. As the name suggests, thunder and lightning sttrikes fall into two types of attacks <br></strong> <br> Lightning attacks are divided into two typeon system, causing serious damage to the monitoring center. As follows: <br><br> <strong>Lightning sng strikes the front-end system, it will directly reach the monitoring center through the transmissis distributed outdoors, they are most likely to be the object of lightning strikes.
