Abstract (en)
[origin: WO2008145460A1] 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.
