Background
A surge protector, also called a lightning protector, is an electronic device for providing safety protection for various electronic equipment, instruments and meters and communication lines. The lightning protection module generally includes a varistor and a discharge tube, and when an instantaneous lightning induced current and a surge overcurrent occur, the resistance of the varistor is instantaneously and rapidly decreased, so that the current is rapidly discharged.
However, when the varistor itself is deteriorated during use, the current in the varistor increases continuously, the temperature rises continuously, a large amount of joule heat is generated, and the protection device may generate spontaneous combustion and endanger the whole circuit.
Most of the existing power supply lightning protection devices adopt a thermal tripping device, low-temperature soldering tin is welded on an electrode plate of a piezoresistor, when the temperature of the electrode plate reaches 130-140 ℃, the low-temperature soldering tin is fused, and a spring pulls a movable electrode plate to rapidly break away from a power grid.
However, the stability of the thermal tripping device is not optimistic, tripping is often performed and the action is finished, but the soldering tin of the welding point is not broken, and the phenomenon of adhesion and wire drawing occurs, so that the phenomenon of fire striking of a lightning protection device or a lightning protection device is caused.
