The invention relates to a novel surge protector comprising a lightning protection element, an over-current protection device, a thermal protection device and a housing. The lightning protection element and the over-current protection device are connected in series to form a surge releasing passage; and the thermal protection device is arranged on a lightning protection element electrode. Besides, the novel surge protector also includes a normally-closed contact, a magnetic field detection device, a detection circuit, a buffer displacement spring plate, an inertial device, an electromagnetic actuating mechanism, and a linkage mechanism; the normally-closed contact is arranged in the surge releasing passage and is connected in series with the lightning protection element and the over-current protection device; the magnetic field detection device is installed near the surge releasing passage and is connected with the electromagnetic actuating mechanism by the detection circuit; the electromagnetic actuating mechanism controls the buffer displacement spring plate to move; the buffer displacement spring plate is connected with the inertial device; and the inertial device controls the normally-closed contact to move by the linkage mechanism. With the novel surge protector, a problem of existence of blind motion areas of the existing thermal protection device and the over-current protection device 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...
