摘要： The invention relates to a thermally triggered, mechanical switching device, consisting of a heat-sensitive means and a mechanical force-storage means, wherein the heat-sensitive means blocks or unblocks the movement path of a switching piece; furthermore, the switching piece is preloaded and held by the mechanical force-storage means, and comprising a housing that accommodates the aforementioned means. According to the invention, the housing is designed as a cartridge-shaped shell which receives a plunger in the interior thereof, which plunger is mounted in a movable manner through a first end-side opening in the housing and is supported against a fusible shaping part under pretension, wherein the fusible shaping part is arranged so as to cover a second opening, which is located opposite the first end-side opening, in such a way that, when the melting temperature of the fusible shaping part is reached, said fusible shaping part is displaced by the plunger and the plunger takes on a changed position.

摘要： The invention relates to a surge protection device having a plurality of surge arresters and, in particular thermal, isolating apparatus which is respectively associated with them together with a fault and state display which is designed as a movable, spring force-prestressed displacement element (17) and has a display area and also an operating area for a telecommunications device, wherein tripping of the fault and state display is performed indirectly by means of a blocking element (1, 2, 3) of which the physical state can be changed. According to the invention, a blocking element is provided for each of the surge arresters, which blocking element is in each case arranged so as to block the movement path (4, 5, 6) of a mechanically prestressed wedge slide (7, 8, 9) with a wedge bevel (12). A rocker lever arrangement is also provided which has first lever arms (13, 14, 15) in accordance with the number of wedge slides and at least one second lever arm (16) for blocking, but also for releasing, the displacement element. Those ends of the first lever arms which are remote from the rotation axis (19) of the rocker lever arrangement each have an area (20) for sensing the respective wedge bevel of the respective wedge slide in such a way that, when the movement path of at least one of the wedge slides is cleared, its wedge bevel lifts the relevant first lever arm, as a result of which the second lever arm releases the displacement element.

摘要： An overvoltage protection device has a plurality of overvoltage arresters and a disconnecting apparatus. For each of the overvoltage arresters a blocking element is present, each of which is arranged so as to block the path of movement of a mechanically preloaded wedge slide having a wedge bevel. A rocker lever arrangement has first lever arms corresponding to the number of wedge slides and at least one second lever arm for blocking or releasing a displacement element, wherein ends of the first lever arms each have a surface for contacting the respective wedge bevel of the wedge slides in such a way that, when the respective path of movement is released, at least one of the wedge slides lifts the corresponding first lever arm with its wedge bevel, as a result of which the second lever arm releases the displacement element.

摘要： The invention relates to a non-rotationally symmetrical spark gap, in particular a horn spark gap with a deion chamber, a multi-part insulating material housing (1) as a support and receiving body for the horn electrodes and the deion chamber, means for conducting the gas flow related to the arc, wherein the insulating material housing (1) is divided on the plane defined by the horn electrodes and has two half shells, and plug or screw connections (4, 5) which lead out on the end face. According to the invention, with the exception of the sections of the plug or screw connections (4, 5) leading out, the insulating material housing is surrounded on all sides by a cooling surface (14) which is near the housing and lies against the housing surface, and the cooling surface (14) is at least partly supported on webs (8) which are designed to conduct the gas flow on the outer surface of the half shells.

摘要： The invention relates to a thermally triggerable indication or switching device, having a movable, mechanically preloaded slide which directly or indirectly triggers or actuates the indication or switching device, and having a preformed part which changes its state of aggregation under the effect of heat, the preformed part, in the functional state, being adapted to be arranged so as to block the movable slide. According to the invention, in the initial state, the preformed part is loosely located in a receiving space. For transferring the preformed part to the functional state, the slide is moved in a position such that a gap space opens between the slide and a slide stop, wherein the preformed part enters the gap space and the slide is simultaneously preloaded.
