Do you want to know what is the ceramic gas discharge tube which plays in the role of lightning surge protection? Do you want to know or want to know if you need to figure out two questions: what is the lightning surge, the working principle and the ceramic gas discharge tube. The engineer with ceramic gas discharge tube for lightning surge protection for some reason, we have the following with electronic technology Xiaobian together to uncover the answers to these two questions!

What is lightning surge:
The lightning surge is through atmospheric discharge induction in a communication line of our energy, voltage because the cable length varies, but the magnitude is s level, the frequency is usually around 100kHz, our equipment through the conduction effect. Influence of lightning surge energy is caused by the greater the degree of protection, when the circuit is not enough, it may damage the precision electronic components within the device, once the precision electronic components are damaged, electronic equipment is not working properly. Now you know why the engineers are going to make lightning surge protection, that is, to minimize the possible damage.

What is the ceramic gas discharge tube:
Ceramic ceramic discharge tube is encapsulated inside by two or more band gap metal electrodes, filled with inert gas argon, neon, when added to the two extreme voltage electric to gas discharge tube gas breakdown when the gas discharge tube to discharge from a high impedance into a low impedance, the surge voltage quick short-circuit to near zero voltage and overcurrent release into the ground, thus protecting the subsequent circuit.

The working principle of ceramic gas discharge tube:
The ceramic discharge tube connected in parallel, the device moves, the resistance is too high, the equivalent capacitance is low, can be regarded as open, almost no impact on the circuit. When the abnormal pulse when the operating voltage value reached after resistance moment decreased, and the release of current. When the abnormal high pressure is lost, it will automatically return to the high resistance state, the circuit is working.
