Abstract

The invention relates to an overvoltage protection arrangement consisting of a horn spark gap accommodated in an insulating housing (1) having a deion chamber. A trigger electrode is located in the ignition area of the horn spark gap. A varistor is also present, electrically connected in series to the horn spark gap. According to the invention, a first and a second disconnection apparatus are formed in the housing, wherein the first disconnection apparatus (2) is in heat-conducting connection with the varistor and, when a limit temperature is reached or exceeded, releases a spring-loaded slide (3) which interrupts the series connection between varistor and horn spark gap. Furthermore, the second disconnection apparatus (13) comprises a fusible conductor which is located inside the deion chamber, for example, and can be exposed there to an arc, wherein the fusible conductor holds a spring-loaded disconnector element (14) in a first position and releases this disconnector element (14) when fused as a result of the effects of the arc in such a manner that the disconnector element (14) adopts a second position, wherein an electrical connection to the trigger electrode is interrupted when the second position is reached. A three-pointed, rotatably mounted star or a circular disc with lugs or prongs is formed in the housing such that a first star point (7) is carried along by the slide (3) as it moves to interrupt the series connection. In the same way, a second star point (16) is carried, as the disconnector element (14) moves, from the first to the second position, wherein each movement of the star results in a rotation of the star around its axis of rotation (17) with the consequence that a third point of the star (10) releases a spring-loaded pivoting lever (8) which operates a remote signalling contact (11) and/or a visual fault status display (12).

Abstract

The invention relates to a single- or multi-pole switching device, in particular for DC applications, having at least one rotating switching element (2) which is connected to a drive, and also comprising switching contacts (4, 5), connection pieces (7) and connection poles or connection terminals (8) and a housing arrangement which accommodates the abovementioned parts. According to the invention, a movably guided rotary cylinder (2) is formed in the housing arrangement, said rotary cylinder being located in a body which is designed as a rotary cylinder holder (1). The rotary cylinder (2) has at least one contact pin (3) which passes radially or tangentially or eccentrically through the rotary cylinder and has, at its end, a contact piece (4) in each case. Mating contact pieces (5) are arranged in the rotary cylinder holder (1), said mating contact pieces being electrically connected to the connection pieces (7) or connection poles or connection terminals (8). A narrow, arc-influencing gap is present between the rotary cylinder (2) and the rotary cylinder holder (1), wherein, as a result of the movement of the rotary cylinder (2), the electrical connection between the contact pieces (4) and the mating contact pieces (5) can be broken by way of the contact pin (3) and the resulting disconnection arcs (11) enter the air gap subject to an extension and are rapidly extinguished there.

Abstract

The invention relates to an overvoltage protection device having one or more parallel-connected voltage-limiting elements which are located in one physical unit, such as varistors, diodes or means of this type configured in the form of a disc, comprising a shell apparatus in order to electrically disconnect the overvoltage-limiting elements when they are thermally overloaded, and means for indication and/or signalling of the fault state which then occurs, wherein the switching apparatus is connected via a means which can be released thermally, such as adhesive or a solder, to a connecting contact of the at least one overvoltage-limiting element, and/or to an external terminal contact or plug contact. According to the invention, the switching apparatus is in the form of a solid U-shaped switching fork, the fork tines of which run essentially parallel to the side surfaces of the overvoltage-limiting element, holding the latter in the space between the tines. At least one of the fork tines rests on the at least one connecting contact and is fixed there via the means which can be released thermally wherein, when disconnection occurs, the disconnection slide is moved with the switching fork being driven and, in the process, the connection point between the fork tines and the connecting contact represents a fulcrum for the switching fork movement.
