摘要： The invention relates to a damage-limiting switching device for surge arresters such as varistors, spark gaps or similar means, comprising a movable switching element, which is conductive or has conductive sections and which is held under mechanical prestress by a fixing device, wherein the fixing device releases the switching element on heating, with the result that said switching element bridges or connects the surge arrester connection contacts or disconnects at least one of the connection contacts. According to the invention, the fixing device is arranged directly at or on the surge arrester at a point with the greatest heating to be expected in the event of overload and has a minimized thermal capacity. In terms of the method, in order to ensure the operation of the damage-limiting switching device, the surge arrester is provided with a separate, erosion-resistant encapsulation in order to collect exhaust heat produced in the event of damage from the resultant arc, wherein the collected thermal energy is supplied in concentrated form to a switching element in the form of a disconnection apparatus or a short-circuiting device for the actuation thereof.

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 running 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 arc running region (11), wherein the plate-shaped insulating material (20) electrically isolates the respective deposit from the electrodes (1, 2). The half-shells also have further, second shaped portions, which engage around an insertable deion chamber part (8) in a form-fitting manner, wherein apertures or openings in the respective half-shell are located between the respective first and second shaped portions, and the shorter (2) of the electrodes ends in front of the deion chamber part (8), with the result that the gas flow only passes partially into the deion chamber.

摘要： The invention relates to an encapsulated surge protection device capable of carrying lightning currents and limiting follow currents and comprising at least one spark gap, which has in each case at least two main electrodes and one auxiliary electrode, which is connected to a starting device for triggering in the event of transient surges. The invention provides a second starting device which is independent of the first starting device and which can activate the spark gap without the need for the presence of surges or pulse currents on the basis of the presence of a minimum voltage between the main electrodes of the spark gap.
