Development History Of Surge Protector

Publish Time: Author: Site Editor Visit: 58

The most primitive surge protector, the 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 protectors, oxide film surge protectors and pill-type surge protectors appeared. In the 1930s, tubular surge protectors appeared. In the 1950s, silicon carbide lightning arresters appeared. In the 1970s, metal oxide surge protectors appeared. Modern high-voltage surge protectors are used not only 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 Britain have also entered China.
