Development History Of Surge Protector

The original surge protection device ram's horn gap appeared in the late 19th century and was used for overhead transmission lines to prevent lightning strikes from damaging equipment insulation and causing power outages. In the 1920s, aluminum surge protector, oxide film surge protective device and pill-type surge protectors appeared. Tube-type surge protectors appeared in the 1930s. Silicon carbide lightning arresters appeared in the 1950s. Metal oxide surge protectors appeared in the 1970s. Modern high-voltage surge protectors are not only used to limit overvoltages caused by lightning in power systems, but also to limit overvoltages caused by system operations. Since 1992, industrial control standard 35mm rail pluggable SPD lightning protection modules represented by Germany and France have begun to be introduced to China on a large scale, and later integrated box-type power supply lightning protection combinations represented by the United States and the United Kingdom have also entered China.
