Abstract
Gas-filled discharge tube for use as transient protection, with at least two electrodes separated by a discharge gap and an insulating body which is joined to the electrodes and, jointly with them, forms a discharge chamber. The sealing of the tube occurs at atmospheric pressure and a suitable temperature, in a mixture of a light and a heavy gas suitable for the purpose, after which the tube is enveloped in a suitable heavy gas at atmospheric pressure, while the temperature is adjusted in such a manner that the light gas enclosed in the tube, through diffusion and a partial pressure difference, exits through the insulating body, whereas the heavy gases can only to an insignificant degree diffuse through the insulating body. The gas diffusion brings about a reduction in the total gas pressure inside the tube and the process is interrupted when the desired pressure drop is obtained.
