    The invention relates to electrical engineering, in particular, to switching devices from overload currents, namely to fuses.
    The aim of the invention is to increase the reliability of operation.
    Fig 1 shows a fuse, a general view; in fig. 2 - the same, with two magnetized ferrite strips; Fig, 3 - for fastening ferrite strips; in fig. 4 - placement of the filament between the ferrite strips; in fig. 5 fuse, option of making gaskets with teeth; in fig. 6 the same, in a perspective view; in fig. 7 variant of fastening of the melting thread; in fig. 8 - fuse in the case. -. ;
    On the ferrite plate 1 (Fig. 1 magnetized in the direction of its mass, so that the north pole is on its lower side, and the south on the upper side, silver is fixed on the thread 2 using two metal rings 3 and 4, which form fuse protection terminals
    tel. The thread 2 has, for example, a diameter of 0.1 mm and a length of 80 mm. According to the law of Laplace, when through this
    the thread is current 3, it is subjected to the action of the force F of the magnetic field n.
    According to the embodiment shown in FIG. 2, a fuse is formed by two
    flexible strips 5 and 6, made of ferrite powder bound by elastomer (plastoferrite). The bands are magnetized in the direction of them trl1schen and mutually attracted.
    They are fixed. opposite each other and held apart from each other in the direction of the tolicycine - by means of two insulating spacers 7 and 8 of the T-shaped.
    The strip 5 is attached to the liners 7 and 8 by gluing, while the strip 6 is detachably magnetically held by the strip 5. The legs of the 9 and 10 T-shaped profiles provide a gap between two magnetized strips, which determines the thickness of the slot 11, in which
    3
    Silver is placed on the thread 12. The transverse size of the groove is determined by an interlayer between the legs 9 and 10. The ends of the thread 12 are fixed and galvanically connected to two terminals, each of which can be formed by a metal collar 13, the ends 14 and 15 of which are bent around each of insulating pads 7 and Q, with the end of the thread 12 bent under the collar (Fig. 3). The end of the thread 12 can also be attached to the yoke. The magnetic top strip provides an easy change of the fusible link.
    In the embodiment illustrated in FIG. 4, the ends of the thread 12 are secured by clamping between two magnetic metal parts 16 and 17, which simultaneously form plugs, closing the ends of the fuse and the end, and the terminals. In accordance with FIG. 2, it is also possible to clamp the thread 12 between two metal plates glued respectively on the upper side of the ferrite strip 5 and the lower side of the ferrite strip 6. In order not to weaken the magnetic field, non-ferromagnetic metals are used, mainly diamagnetic, ferritic strips: they may have, for example, a length 50 mm width 10 mm and thickness 1.8 mm with an interval of 1.5 mm.
    It is possible to increase the efficiency of the magnetic arc arc blowing using insulating gaskets 18 and 19 (Figs. 5 and 6). The legs of the ISOLIZING gaskets 18. and 19 are provided with teeth 20 and 21, which enter between the ferrite strips 6 and 7, and the teeth form two combs, each of which are arranged opposite each other, while
    709794 windows 22 and 23 between the teeth form chambers for cooling and extinguishing the arc. The legs and teeth of the pads 18 and 19 have a length of 5 dl for Toroj to melt the thread 12, moreover, it is mechanically held between the teeth and thus withstands mechanical shocks without breaking. Quench chambers can communicate with the outside space through the holes 24, which continue the chambers and also favor the deflation of the arc and the ejection of metal particles. When there is no 5 holes, these holes can
    be closed with adhesive tapes 25 and 26 shown in dash-and-dot lines. At the ends of the thread 12 is clamped more widely and the teeth of 20 27 and 28 izoliruntsih gaskets. The ends of the filament can be connected to the terminals by clamping or soldering (Figs. 5 and 6). The thread can be bent into the slot 29 of one of the gaskets 25 and under the metal ring 30 (Fig. 7).
    You can significantly increase the magnetic field, i.e. its blowing effect, using a ferromagnetic body. This embodiment is represented in FIG. 8, where the body is formed from a soft iron sheet of 31 0 -shaped shape. With this case, you can punch, a magnetic field of 1200-1300 Gs against the floor of 500-650 Gs without a body. The forces acting in this case on the filament and the arc are very high.
    The proposed fuse has a high breaking rate and provides almost absolute protection of the circuit elements due to the increased breaking rate, it is easy to manufacture, it can be replaced 5 and even cleaned.
