Abstract
The invention provides a gas discharge tube, which comprises at least one insulating tube body, a first electrode and a second electrode, wherein the first electrode and the second electrode are tightly connected with two ends of the insulating tube body to form an discharge inner cavity respectively; the first electrode is tightly connected with the insulating tube body through a low-temperature seal adhesive; and the clear height of an emitting surface, which extends into the discharge inner cavity, of the first electrode is greater than 0 and smaller than or equal to 1.5mm. The gas discharge tube can play a role in discharging a lightning current or an overvoltage when subjected to a lightning stroke or a surge overvoltage; and furthermore, the sealing state is a failure when the gas discharge tube warms to fuse the low-temperature seal adhesive due to heating after being subjected to a certain continuous current or excessive current. The clear height of the emitting surface of each electrode is very small, so that external air can quickly enter and contact the emitting surface for air blowout; and a follow-up current is quickly cut off.
