    摘要: The invention relates to an overvoltage protection device with at least one overvoltage protection unit, consisting of a socket part and a plug part which can be connected to the socket part and which receives means for protecting against an overvoltage, wherein insulated electric conductors can be introduced into the socket part, said electric conductors being contacted using vampire or cutting clamps, thereby penetrating the conductor insulation, and with contact surfaces which can be found on the socket part and which correspond to mating contact surfaces on the base of the plug part. According to the invention, the socket part is made of multiple parts consisting of a base part and a lever part. The base part is designed as a marble panel and has multiple parallel grooves for inserting and receiving the insulated electric conductors. On one face of the base part, hook-shaped protrusions are provided parallel to the grooves. The lever part has axle stubs, which engage into the hook-shaped protrusions, on one lever end. The lever part has at least one cutting clamp on the lever part lower face facing the marble panel and in the vicinity of the axle stubs, wherein the cutting clamp leads to a plug contact which can be found in the lever part and which can be accessed from the upper face of the lever part in order to receive the plug part.

    摘要: The invention relates to an arrangement for non-reversible detection and display of electrical overcurrents or current limit values by means of a pre-finished conductor. The conductor according to the invention has at least two conductor sections, spaced apart from each other and extending parallel to each other, which are designed for current to flow through in the same direction. At least one of the parallel conductor sections has a protrusion, a nose, or similar blocking element, which limits the path of movement of a mechanical display or switching element, such that the electromagnetic force acting on the parallel conductor sections during the flow of current transitions the blocking element into a release position in respect of the path of movement of the mechanical display or switching element. Such an arrangement can be used particularly advantageously as a prior damage indicator in surge arresters.

    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 disconnecting device for a surge arrester which is accommodated by a support body, and wherein plug contacts which are connected to at least one arrester element of the surge arrester extend from the support body. The invention further comprises a switching tongue which is connected at a first end to the arrester element via a thermal separating point and with a second end to one of the plug contacts. Furthermore, a spring-preloaded insulating disconnecting bracket which is pivotably mounted on the support body is provided, the spring preload acting on the thermal separating point via the switching tongue. According to the invention, the switching tongue is configured as a straight-surface, elongated, metallic, resiliently elastic disconnecting strip having a rectangular cross-section.
