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.

摘要： The invention relates to a disconnection and switch-over device for overvoltage protection, particularly for DC systems, comprising at least one arresting element, and a thermal cut-off point incorporated into the electrical interconnect path of the arresting element, the thermal cut-off point comprising a movable mechanically prestressed conductor element that moves from a first position to a second position in the event of a cut-off, and when the second position is reached, an electrical switch-over to a safety device is generated, and the thermal cut-off point is formed by the movable conductor element and a stationary contact element, the movable conductor element being attached to the stationary contact element by a thermally releasable means. According to the invention, a completely electrical cut-off of the arresting element regarding the interconnect path only occurs when the movable conductor element has gone beyond the second position and has reached a third position, the safety device being arranged in series with the arresting element and the movable conductor element being designed as a wiper or sliding contact in relation to the second position, the second position being created by a bypass end point.

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.

摘要： The invention relates to a lightning and overvoltage protection device for data networks, telephony services, electroacoustic installations or bus systems having at least two grid-side input terminals and at least two output terminals, to which the load that is to be protected can be connected, furthermore having a gas-discharge surge arrester that connects the input terminals and an inductance located between the respective input and output terminal. According to the invention, the inductances are configured as current-compensated inductors having a core and a primary winding and a secondary winding, wherein the load current flows through the windings in different directions so that the respective magnetic fields cancel out. In the event of transient overvoltages, the arising surge current is bypassed by means of a switching device that then closes at one of the two windings, for example the secondary winding, in such a way that, owing to the winding through which current flows, for example the primary winding, the core reaches saturation and the coupling between the windings is released, with the result that no voltage is established across the load and the voltage applied to the winding through which current flows ignites the gas-discharge surge arrester.
