Abstract

The invention relates to a novel surge protector comprising a lightning protection component, a power current suppressor, a magnetic field sensor, an energy conversion device, an over-current protection device, a thermal protection device, a delay stepping electromagnet, a sensing plate, a breaking contact, a tripping mechanism, an arc extinguishing gate, an arc-extinguishing magnetic blow-out plate, and an upper wiring terminal and a lower wiring terminal. According to the invention, the magnetic field sensor can sense the magnetic filed next to the lightning protection component; the energy conversion device carries out conversion to obtain a current; the corresponding current is inputted into the delay stepping electromagnet; the delay stepping electromagnet actuates a series of mechanical linkages; and then the breaking contact is disconnected to enable a surge releasing passage to be disconnected. Therefore, the surge protector can be protected well.

Description

technical field [0001] The invention belongs to the technical field of surge protection for electronic and electric equipment. Background technique [0002] Lightning is a special weather phenomenon caused by the discharge of charged clouds in the air. Lightning is an important cause of damage to electronic equipment, which threatens the safe and stable operation of electronic information systems in various fields such as construction, railways, civil aviation, communications, industrial control, and military. Installing surge protectors on metal lines such as power lines, signal lines, and control lines connected to electronic equipment is one of the important measures for lightning protection. Surge protectors have been widely used in various fields and play an important role in lightning protection. The quality of its state directly affects its lightning protection effect, thus bringing hidden dangers to the safety of the protected equipment. [0003] At this stage, SP...
