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 surge arrester having a housing (10) and at least one arresting element, for example a varistor, as well as a disconnection apparatus, in order to disconnect the arresting element or elements from the power supply system, with the disconnection apparatus having a solder point (14) which is connected in the electrical connecting path (A, B) within the arresting means, with a moving conductor section or a moving conductive link being connected via the solder point to the arresting element on the one hand, and with the conductor section or the link (3) being connected on the other hand to a first electrical external connection of the arresting means, and having means to produce a prestressing force, for example a spring (6, 11), with the force vector relating to them acting indirectly or directly via a moving separating block (13) on the conductor section or on the link in the disconnection direction. According to the invention, a conductive element (4, 17) is arranged in the movement path of the conductor section or of the link with its first end making contact with the conductor section or the link when the disconnection apparatus has been tripped, with its second end being connected to a second electrical external connection, and with means also being provided for protection of the contact point between the conductor section or link and the conductive element against solder residue being splashed out or dissolved materials of the conductor section or of the link.

摘要： The invention relates to a short-circuiting device for surge arresters such as varistors, spark gaps, or similar elements, comprising a flexible conductive short-circuiting device or short-circuiting devices having conductive sections, which is held by a fixing device under mechanical pretension, wherein the fixing device is released upon warming of the short-circuiting device such that the short-circuiting device bridges or connects the surge arrester connection contacts. According to the invention, the fixing device is arranged at a point determined to have the greatest amount of heating in the case of an overload immediately up to or on the surge arrester and configured above a minimized heat capacity, wherein neither the short-circuiting device nor the fixed device is part of the elements of the surge arrester that carry the current in the case of normal operation.
