Novel surge protector

Abstract

The invention relates to a novel surge protector comprising a lightning protection element, a power current suppressor, a magnetic field sensor, an energy conversion device, an over-current protection device, a thermal protection device, a time delay stepping electromagnet, an induction piece, a breaking contact, a tripping mechanism, an arc extinguishing gate, an arc extinguishing magnetic blow-out board, a signal detector, a signal transmission line, an over-current protection device detector, a data unit, a connecting line, a connecting terminal, and an upper wiring terminal and a lower wiring terminal. The magnetic field sensor the magnetic filed next to the lightning protection element; the energy conversion device converts the magnetic field into a current; the corresponding current is inputted into the time delay stepping electromagnet; a series of mechanical linkages are caused by the time delay stepping electromagnet; the breaking contact is disconnected to disconnect the surge releasing passage. Therefore, a problem of a potential safety hazard caused by unknown motion blind areas of the existing thermal protection device and over-current protection device, the unknown motion situation of the thermal protection device, and the unknown working situation of the lightning protection element can be solved.

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...
