Problems solved by technology

If the external network voltage or current changes for a long time, the discharge tube will be in the conduction state for a long time, which will cause the discharge tube or varistor to overheat
[0005] If the discharge tube or varistor is overheated for a long time, it will cause the lightning protection module to catch fire

Abstract

The invention discloses a lightning protection module. The lightning protection module (4) comprises a main body part (6) and a connecting part (22), wherein the connecting part is used for being electrically connected with a PLC (programmable logic controller); the main body part comprises a discharging tube (7), a voltage dependent resistor (8) and a pressure bar (9); the connecting part comprises a switch spring leaf (10) used for being electrically connected with the PLC; when the lightning protection module is normal, the pressure bar presses the switch spring leaf; and when the discharging tube or the voltage dependent resistor is overheated, the pressure bar leaves the switch spring leaf, so that the switch spring leaf is bounced. After the switch spring leaf electrically connected with the PLC is arranged on the connecting part of the lightning protection module, when the discharging tube or the voltage dependent resistor of the lightning protection module is overheated, the switch spring leaf is bounced, signals are sent to the PLC, and signals indicating that the lightning protection module is overheated can be timely sent to an operator, so that the lightning protection module can be prevented from catching fire when the lightning protection module is overheated.

Description

technical field [0001] The invention relates to a lightning protection module. Background technique [0002] Usually the so-called lightning strike refers to the rapid discharge between a part of the charged cloud layer and another part of the cloud layer with different charges, or between the charged cloud layer and the earth. This rapid discharge produces an intense flash of light accompanied by a loud sound. Of course, the discharge between the clouds is mainly harmful to the aircraft, and has no great impact on the buildings, people and animals on the ground. However, the discharge of the cloud layer to the earth is very harmful to buildings, electrical and electronic equipment, and people and animals. [0003] Due to the effect of electrostatic induction, the charged cloud layer causes a certain area of ​​the ground to be charged with a different kind of charge. When the direct lightning strike occurs, the charge on the cloud layer disappears quickly, and some areas o...
