Abstract

Die Erfindung beschreibt einen elektrischen Widerstand (1), insbesondere einen Selektivwiderstand für einen selektiven Hauptleitungsschutzschalter, mit einem Widerstandselement (2) und mindestens zwei dem Widerstandselement (2) zugeordneten Anschlussstücken (3, 4). Das Widerstandselement (2) ist aus einem Stapel von Teil-Blechstücken (3, 5,6,7,8,9,10, 11, 4) gebildet, die aus einem Widerstandsblechmaterial bestehen, wobei die Teil-Blechstücke (3, 5,6,7,8,9,10, 11, 4) mit ihren Breitseiten parallel zueinander und in Stapelrichtung hintereinander und voneinander beabstandet angeordnet sind, wobei benachbarte Teil-Blechstücke (3, 5,6,7,8,9,10, 11, 4) in Stapelrichtung abwechselnd rechts und links einer senkrecht zu der Breitseite der Teil-Blechstücke (3,5,6,7,8,9,10,11, 4) verlaufenden Mittelebene an ihren Schmalseiten elektrisch miteinander verbunden sind, so dass der Strompfad von dem ersten, randständigen Blechstück (3) zu dem in Stapelrichtung gegenüberliegenden, zweiten randständigen Blechstück (4) mäanderförmig durch die übrigen Teil-Blechstücke (5,6,7,8,9,10, 11) verläuft.The invention relates to an electrical resistor (1), in particular a selective resistor for a selective main circuit breaker, comprising a resistance element (2) and at least two connecting pieces (3, 4) associated with the resistance element (2). The resistance element (2) is formed from a stack of partial sheet metal pieces (3, 5, 6, 7, 8, 9, 10, 11, 4) which consist of a resistance sheet material, wherein the partial sheet pieces (3, 5, 6,7,8,9,10, 11, 4) are arranged with their broad sides parallel to each other and in the stacking direction one behind the other and spaced from each other, wherein adjacent part sheet metal pieces (3, 5,6,7,8,9,10, 11 , 4) in the stacking direction alternately right and left of a perpendicular to the broad side of the partial sheet metal pieces (3,5,6,7,8,9,10,11, 4) extending center plane are electrically connected to each other at their narrow sides, so that the Current path from the first edge sheet metal piece (3) to the opposite stacking direction, the second edge sheet metal piece (4) meandering through the remaining part sheet metal pieces (5,6,7,8,9,10, 11).

Weiter betrifft die Erfindung ein Verfahren zur Herstellung eines solchen Widerstandes, und ein elektrisches Installationsschaltgerät mit einem solchen Widerstand.
