Abstract
A gas-filled spark gap for the protection of an electrical installation includes a gastight casing and two elongate electrodes delimiting between them an inter-electrode space. The inter-electrode space includes successively a striking chamber and an arc-extinguishing chamber for extinguishing the electrical arc. The arc-extinguishing chamber includes mutually spaced divider plates. The gas-filled spark gap also includes two connecting terminals accessible from outside the casing and intended to enable electrical connection of the gas-filled spark gap to the electrical installation. The two connecting terminals are respectively electrically connected to the two elongate electrodes. Finally, the gas-filled spark gap includes an inert gas trapped in the casing.
