Abstract

Antipyretic protection device for gas unloader supports, especially applicable to bipolar tibo tubular unloaders, consisting of a cylindrical conductive housing, closed in one piece by one of its ends and with its mouth closed by means of a disc of insulating material, of which a cylindrical electrode emerges axially, essentially characterized in that the discharger is installed in the bosom of the corresponding support with the possibility of axial displacement, establishing a spring between the conductive base of said discharger and the corresponding contact that tends to project said discharger towards the plate. Grounding, having provided that the casing of the discharger is kept separated from the grounding plate with the collaboration of a conductive bushing with low melting point, threaded under pressure in the electrode of the discharger, supported on the insulating disk of the latter and acting as stop over the earthing relay, which incorporates a perforation through which the electrode is passing, all this in such a way that before an overheating of the assembly, due to the existence of a permanent discharge regime, upon reaching a certain temperature it it produces the fusion of the conductive bushing, with which the spring axially projects the discharger until its conductive casing contacts directly with the earthing plate, eliminating the arc effect and interrupting the thermal dissipation process.
