Lightning protection and lightning protection products - lightning arrester The lightning arrester includes: a power surge protector and a signal lightning protector, the lightning arrester is also called a lightning arrester, a surge protector, a surge protector (SPG), and an overvoltage protector. The lightning arrester is a device that prevents lightning strikes through modern electrical and other technologies. The lightning energy absorption in the arrester is mainly a zinc oxide varistor and a gas discharge tube. The lightning arrester mainly includes: a power surge protector and a signal lightning protector. Definition and composition The lightning arrester includes: a power surge protector and a signal lightning protector, and an antenna feed surge protector. The lightning arrester is also named: lightning arrester, surge protector, surge protector, abbreviation, SPD. In the information age today, computer networks and communication equipment are becoming more and more sophisticated, and the requirements of their working environment are getting higher and higher. The instantaneous overvoltage of lightning and large electrical equipment will pass the power, antenna and radio signals more and more frequently. Lines such as transceivers invade indoor electrical equipment and network equipment, causing damage to equipment or components, causing personal injury or death, data transmitted or stored being disturbed or lost, or even causing electronic equipment to malfunction or temporarily paralyze, system stalls, and data transmission is interrupted. The LAN and even the WAN were damaged. The damage is shocking, and the indirect losses are generally far greater than the direct economic losses. The lightning arrester is a device that prevents lightning strikes through modern electricity and other technologies. Historical origin The most original lightning arrester is a horn-shaped gap, which appeared in the late 19th century and was used for overhead transmission lines to prevent lightning damage to equipment insulation and cause power outages. It is called “salierâ€. In the 1920s, aluminum lightning arresters, oxide film surge arresters and pellet arresters appeared. A tube arrester appeared in the 1930s. Silicon carbide lightning arresters appeared in the 1950s. Metal oxide surge protectors appeared in the 1970s. Modern high-voltage lightning arresters are not only used to limit overvoltages caused by lightning in power systems, but also to limit overvoltages caused by system operation. Magnetostrictive level sensor is composed of three parts: probe rod, circuit unit and float. To measure, the circuit unit generates pulses of current that travel down the magnetostrictive line and generate a circular magnetic field. A float is arranged outside the probe rod, and the float moves up and down along the probe rod with the change of liquid level. The float generates a magnetic field at the same time because it is fitted with a set of permanent magnets. When the current magnetic field meets the float magnetic field, it produces a "twisting" or "return" pulse. The time difference between the "return" pulse and the current pulse is converted into pulse signals to calculate the actual position of the float and measure the liquid level.
