Definitions
- the invention relates to a fuse, in particular a high-performance fuse, with at least one fusible conductor, mechanical means Cutting the fusible conductor and mechanical means for triggering the mechanical severing.
- a fuse in particular a high-performance fuse, with at least one fusible conductor, mechanical means Cutting the fusible conductor and mechanical means for triggering the mechanical severing.
- Such fuses are preferred used in the medium voltage range, although they are in professional 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 their parts designed for this purpose, the circuit in which it is inserted, to interrupt.
- the circuit parts separating fused conductors be provided or melt inserts are used, which interrupt the circuit by melting when a current exceeds a given value for a sufficiently long period of time.
- High-voltage high-performance fuses usually made of a ceramic tube body, at its ends provided with conductive contact caps. Inside the tube body are mounted on a ceramic insulator fusible link which electrically connected to the contact caps. The whole The fusible link structure is embedded in a quartz sand pad, which is the Cooling or clearing a fuse when the fuse is activated Arc serves. Et al this is the high performance behavior reached the fuses.
- HH fuses have a current-limiting and selective effect and dissolve Melting of the fusible conductor automatically. They will in particular for the protection of equipment, preferably in medium voltage networks energy supply companies and industry.
- a fuse of the type mentioned is known from US 4,369,420 or DE 196 07 756 C1 known, with a current safely and detectably interrupted can be provided by means according to the preamble of claim 1 for mechanically separating the Schmelzeiters are.
- the locking device is to release the energy storage either by a thermal or an electrical guard, in parallel are connected to the fuse element and interact with it, triggered.
- the electrical monitor reacts to short-circuit currents, while the thermal guard against one over a certain Period of continuous overload secures.
- the separating rod is a shear rod educated.
- the shear rod is pivotable over one at one end mounted lever arm, which acts on a compression spring, in the direction of his Longitudinal axis drivable.
- the lever arm is counter to the force of the compression spring by a retaining wire held around the lever arm.
- the one end of the retaining wire is held by a selective solder joint, which is the Function of the thermal guard has.
- the other end of the retaining wire is connected to a resistance wire.
- the retaining wire gives the lever arm either in the case of a thermal Release free when the solder joint under the influence of small Overflowing resulting heat melts, or in the case of an electrical Tripping when due to the voltage drop at the first occurring Melting arcs within the fusible conductor a current shift takes place on the resistance wire, the latter to melt through brings.
- This version may be in one of the contact caps be housed in the tubular body of the fuse.
- the present invention is based on the object, the aforementioned Fuse, in particular those known from US 4,369,420 High-voltage high-performance fuse, so to further develop that the functional effectiveness and the spatial allocation of the components is optimized, without requiring additional space results.
- the means for triggering the mechanical Cutting through a pressure capsule include.
- the pressure capsule acts in such a way that when released triggers gas under pressure releases. This pressure acts on the means for mechanical severing of the fusible conductor so that the latter are also moved abruptly with the consequence that the fusible conductor ruptured and the circuit thus safely interrupted.
- the pressure capsule can be designed in particular as a gas generator and, for example, a propellant charge or a pyrotechnic charge exhibit. But it is also a gas cartridge conceivable, the gas under contains very high pressure, which releases with release of the pressure capsule and then act on the means for mechanical severing can.
- a pressure capsule By using a pressure capsule can in particular to the use of comparatively strong springs, previously used to apply the necessary Forces used for mechanical cutting of the fusible link were waived. Also can about a pressure capsule a much greater force than generated by the springs. From this results in the possibility of the means of triggering the mechanical Separating and the means for mechanical cutting more compact perform as it was previously possible. So can easily a Full-range backup for all HH fuses, their design types and Dimensions are standardized in DIN 43 625, realized.
- the pressure capsule is triggered mechanically.

- the release means of a thermal release in particular consist of a selective solder joint.
- the selective solder joint melts due to continuous overload and not dissipated heat, so that this gives an effective overload protection is.
- the retaining wire both held in an overload as well as a short circuit Element free. In this way, the backup acts as a full-range backup.
- the means for mechanical cutting of the melt insert have prefers a shear bar with at least one groove into which or engage the fusible link, the shear rod in the direction of his Longitudinal axis is movably mounted and with one or the fusible link holding fusible conductor carrier cooperates.
- the shear rod namely abruptly relative to Fusible conductor carrier moves, so that in the fuse carrier and the shearing rod engaging fusible link is torn. This will the fusible conductor destroyed so that another by a Electricity generated arc is safe to exclude.
- the pressure capsule facing the end of the shear rod in be led by a recording and an expansion chamber with the Pressure capsule communicate.
- the ignition mechanism for the pressure capsule, the pressure capsule itself, the expansion space and the shear bar along an axis, in particular be arranged along the longitudinal axis of the fuse can.
- the separation effect can be especially for small size fuses be improved by the fact that the fuse carrier in Direction of its longitudinal axis is movably mounted and when triggered the means for mechanical severing in the direction of movement the shear rod opposite direction is moved. For this can the fuse carrier against a spring force from a locking device be held at the time of release of the pressure capsule releases the fuse carrier.
