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

Use of a high voltage high rupturing capacity (HV HRC) fuse for a drop-out fuse system with a drop-out release mechanism,

• wherein the high voltage high rupturing capacity fuse 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, wherein the fuse housing is designed to be at least partially open on two end faces, wherein upper and lower contact caps are respectively arranged on the end faces of the fuse housing;
• wherein 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;
• wherein the drop-out release mechanism is configured such that tripping of the high voltage high rupturing capacity 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 high voltage high rupturing capacity fuse swings out from the contacting position to a swing-out position;
• wherein the winding body is designed as a hollow body, and wherein an inner winding body is designed as a hollow body arranged in the winding body and a secondary melting conductor is arranged in the inner winding body;
• and
• wherein the high voltage high rupturing capacity fuse has a spring-loaded stroke pin movably mounted in the fuse housing and held in the fuse housing and wherein the stroke pin reaches a minimum travel length required to trigger the drop-out release mechanism within a stroke pin travel time and exerts a force of at least 90 N on a triggering means of the drop-out release mechanism for triggering upon release.
