Definitions
- the invention relates to a fuse, in particular a high-performance fuse, with at least one fuse element, means for mechanical Cutting the fuse element and means for triggering the mechanical cutting.
- a fuse in particular a high-performance fuse, with at least one fuse element, means for mechanical Cutting the fuse element and means for triggering the mechanical cutting.
- Such fuses are preferred used in the medium voltage range, although in specialist circles High-voltage fuses or high-voltage high-performance fuses to be named.
- a fuse is used to connect a circuit to one or more its parts designed for this purpose the circuit in which it is inserted, to interrupt.
- Fusible conductors can be used as parts separating the circuit be provided or melting inserts are used, which break the circuit by melting when there is a current exceeds a given value for a sufficiently long period of time.
- High-voltage, high-performance fuses exist usually from a ceramic tube body, which at its ends is provided with conductive contact caps. Inside the tube body are fused on a ceramic insulating body, the are electrically connected to the contact caps.
- the whole Fusible conductor structure is embedded in a quartz sand cushion, which the Cooling or the deletion of one that arises when activating the backup Arc serves. Among other things this makes the high-performance behavior of fuses reached.
- HV fuses have a current-limiting and selective effect and trip Melt the fuse element automatically. You will be particular to protect equipment, preferably in medium-voltage networks of energy supply companies and industry.
- a fuse of the type mentioned at the outset is from DE 196 07 756 C1 known with which a current can be interrupted safely and verifiably can be provided by means of mechanical separation of the fuse element are.
- the fuse element becomes essentially spiral around the longitudinal axis a fuse element carrier and one parallel to the fuse element carrier arranged, designed as a torsion bar or shear bar wrapped.
