摘要： The invention relates to a disconnecting and switching circuit for the overvoltage protection comprising at least one dissipation element, further one thermal disconnecting point which is integrated in the electrical connection path of the dissipation element, wherein the thermal disconnecting point comprises a movable conductor element, which is under a mechanical pretension and which, in the event of disconnecting, moves from a first position into a second position, wherein by reaching a second position an electrical switching is brought about, wherein a complete electrical disconnection of the dissipation element in relation to the connection path is only given once the movable conductor element has reached the second position. According to the invention, the thermal disconnecting point is formed by the movable conductor element and a fixed contact element, wherein the movable conductor element is fastened to the fixed contact element by a thermally detachable means and the contact element has a groove or an opening, in which a finger-like extension of the movable conductor element immerses in such a way that a disconnection between groove or opening and finger-shaped extension is only given when the second position of the movable conductor element is given.

摘要： The invention relates to a short-circuiting device for use in low-voltage and medium-voltage systems for the protection of parts and personnel, comprising a switching element, which can be actuated by the tripping signal of a fault detection device, two mutually opposite contact electrodes having power supply means, wherein contact can be made with said contact electrodes at a circuit having connections at different potentials, furthermore the contact electrodes, under mechanical prestress, carry out a relative movement in relation to one another in the event of a short-circuit assisted by spring force, and a further part short-circuits the contact electrodes in a relative movement with respect to said contact electrodes, a sacrificial element as the spacer between the contact electrodes and having an electrical connection between the sacrificial element and the switching element, on the one hand, and one of the contact electrodes, on the other hand, in order to bring about thermal destruction of the sacrificial element in a targeted manner owing to current flow. In a first embodiment of the invention, the sacrificial element is a thin-walled hollow cylinder consisting of a high-melting metallic material. In a second embodiment of the invention, the sacrificial element is a wire or rod consisting of a conductive material having a low melting integral, wherein the sacrificial element is under mechanical prestress under tension in contrast to the first embodiment.

摘要： The invention relates to an encapsulated secondary-current-limiting voltage surge diverter based on a spark gap, for low-voltage applications, comprising two main electrodes and with insulating pieces which release gas on temperature loading, whereby one of the main electrodes is at least part of the capsule and/or the spark gap housing. According to the invention, the capsule or the spark gap housing has an essentially elongated parallelepiped form, with an arc chamber and at least two separate expansion chambers embodied in the parallelepiped, such as to extend over the total height of the parallelepiped. The expansion chambers are connected to the arc chamber by means of channels and the arc chamber and the expansion chambers run essentially parallel to each other. The arc chamber is defined in the head region by one of the main electrodes and an insulating piece and, in the opposing base region, is formed by an arc extending piece, electrically connected to the other main electrode. The channels run laterally from the arc extending piece to the expansion chambers. In at least one channel and/or one expansion chamber, further insulating pieces or insulating sections may be provided, which on arcing and temperature rise give off gas to produce a back pressure.

摘要： The invention relates to a lightning arrester comprising two divergent electrodes, a spark gap acting between the electrodes, a housing, an auxiliary sliding device for the electric arc, which is active on the electrode base, and means for the magnetic blow-out of the electric arc. According to the invention, the mobility of the electric arc is increased directly after the ignition thereof, by means of a combination of measures for reinforcing the inherent magnetic field related to the electric arc, and a phased gas circulation of the encapsulated conducting lead.

摘要： The invention relates to an encapsulated spark-gap based surge voltage protector comprising large-surface, opposite lying, disk-shaped electrodes in a rotationally symmetrical arrangement in addition to an arc discharge gap which is disposed between the electrodes and which is at least partially encompassed by an impact wall. According to the invention, a first impact wall is arranged in such a way that it is directed from one of the electrodes, protruding above the spark-gap, towards the opposite electrode. A second parallel impact wall is arranged in such a way that it is radially distanced in an outward direction from the first impact wall in relation to the rotationally symmetrical structure. The existing impact walls form a meander shape through which the arc discharge pressure wave passes. Insulation paths which are protected against deposits are disposed downstream from the direction of flow, whereby the desired long-term properties and required degree of reliability of the spark gap are achieved.

摘要： The invention relates to a plug-in combination of appliances for protecting against overvoltages, said combination of appliances comprising: a socket-type lower part and at least one plug-in module, which can both receive overvoltage protection elements; contact elements and contact counter elements that are respectively arranged in the lower part and in the plug-in module; and complementary guide rails or guide grooves for inserting or pushing-on and fixing the respective plug-in module. According to the invention, functionally separated, mechanical catch or snap-in elements act between the respective plug-in module and the socket-type lower part independently of the forces which hold together the contact elements and the contact counter elements in a positively fixed and/or non-positively fixed manner when the plug-in module is in use. The catch or snap-in function can be cancelled without any mechanical auxiliary means when the respective plug-in module is to be replaced.
