A HV HRC fuse, in particular a HH full-range fuse, for a drop-out fuse system with a drop-out release mechanism has an outer fuse housing, wherein at least one melting conductor, which is wound around at least one winding body, is provided in the fuse housing. The fuse housing is at least partially open on two end faces and a contact cap designed for electrical contacting is arranged on each end face of the fuse housing. The upper contact cap is detachably connectable in a contacting position with the drop-out release mechanism and the lower contact cap is pivotally mounted on the drop-out release mechanism. Tripping of the HV HRC fuse results in tripping of the drop-out release mechanism, whereby the upper contact cap is separated from the drop-out release mechanism and the HV HRC fuse swings out from the contacting position to a swing-out position.

Use of a HV HRC fuse for a drop-out fuse system

The invention relates to an use of a melting conductor () for a DC fuse () and a high-voltage high-power fuse () (HH-DC fuse), wherein the melting conductor () comprises an electrically conductive melting wire (), wherein the melting wire () comprises at least two overload narrow sections () in the form of a cross-sectional constriction, wherein, preferably between the two immediately successive overload narrow sections () a first layer () comprising solder and/or surrounding the outer shell surface () of the melting wire () circumferentially at least in some areas, preferably completely, is provided in at least one first section (), and wherein a second layer () surrounding the outer shell surface () of the melting wire () circumferentially at least in some areas, preferably completely, is provided adjacent to each of the overload narrow sections () in a respective second section ().

Melting conductor and fuse

The invention relates to a use of a high-voltage high-power fuse for securing direct current transmission, wherein the direct voltage of the direct current and/or the rated voltage of the high voltage fuse () is greater than 4 kV.
