摘要： 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).

摘要： The invention relates to a horn, spark gap with, a deion chamber (8) with, a non-blowout design having a multi-part insulating housing as supporting and accommodating body for the horn electrodes (1, 2) and the deion chamber (8) and means for conducting the arc-induced gas flow, wherein the insulating housing is divided in the plane spanned by the horn electrodes and forms a first and a second half-shell. According to the invention, the horn electrodes (1, 2) have an asymmetrical form. The arc naming region (11) between the electrodes is delimited in the direction of the deion chamber by a plate-shaped insulating material (20), wherein the plate-shaped insulating material (20) is inserted into a respective first shaped portion of the respective half-shell in a form-fitting manner. Furthermore, the first shaped portions accommodate a ferromagnetic deposit (21) of the are running region (11).
