Description
Technical Field
[0001] The utility model relates to the technical field of lightning protection, in particular to a surge protector module box capable of recording lightning strike parameters and a surge protector. Background Art
[0002] SPD, or surge protector, is also called lightning arrester. It is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. In a low-voltage power distribution system, when a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, such as overvoltage caused by lightning, thereby avoiding damage to other equipment in the circuit caused by the surge. The SPD surge protector can discharge lightning current and protect electrical equipment from lightning strikes. Existing surge protectors can only discharge the lightning current that occurs, and do not have the function of recording parameters such as the lightning current size and the number of lightning strikes, making it difficult to determine the remaining life of the surge protector.
