Abstract (en)

The invention relates to a high-voltage fuse in which a cover plate (2) of a first electrical connection is connected to a separating plate (6) via a fuse element consisting of silver-coated strips (7) in an electrically conductive manner. A reactor is connected to said separating plate, which reactor has a coil (8) enclosing a core which is provided in the form of a solid ferrite bar (9). Said coil connects the separating plate (6) to a cover plate (4) of a second electrical connection in an electrically conductive manner. Alternatively, in order to save space, the fuse element can be arranged in an opening in the hollow core and can be connected to the coil via a return line. Said high-voltage fuse provides a means of connecting branches of a power supply system to a low-voltage line and a means of preventing the distribution of the high-frequency signals used for communication between appliances of one branch to other branches.

Abstract (de)

Eine Abschlussplatte (2) eines ersten elektrischen Anschlusses ist durch einen aus Silbermantelbändern (7) bestehenden Schmelzleiter mit einer Trennplatte (6) elektrisch leitend verbunden, an welche eine Drossel anschliesst mit einer Wicklung (8), welche einen als massiver Stab (9) aus Ferrit ausgebildeten Kern umgibt und die Trennplatte (6) mit einer Abschlussplatte (4) eines zweiten elektrisch leitenden Anschlusses elektrisch leitend verbindet. Alternativ kann der Schmelzleiter in platzsparender Weise in einer Durchführung im hohl ausgebildeten Kern angeordnet und über eine Rückleitung mit der Wicklung verbunden sein. <IMAGE>
