    salmon composition. Partitions of insulating material are made in the form of a set of elements 7, each of which has stepped protrusions on one side and stepped depressions on the other. When assembled, the protrusions of a single element enter the basin.
    The invention relates to electrical engineering and can be used in {switching equipment for arc extinction.
    The purpose of the invention is to increase reliability and manufacturability.
    FIG. 1 shows an arc suppression plate, top view; in fig. 2 isolation partition, top view; in fig. 3 shows section A-A in FIG. in fig. 4 - arc chamber, section; in fig. 5 - arcing chamber assembly, side view; 6 is the same, one of a pair of arcing horns,
    The arcing chamber consists of a package of steel arc-extinguishing plasgtin 1 of rectangular shape. Each plate has a cutout that forms a pair of spaced parallel tips 2 and 3 of rectangular cross section with rounded ends 4. At the end portion 5, remote from the tips, the plate is covered with an insulating composition. In the plates 1 are made coaxial. holes 6 for assembling them into the bag. Each: element 7 of the insulating partition on one side has a stepped depression 8, and on the other, a step ledge 9. When assembling the interrupter chamber, the projection 9 of one element enters the depression 8 of another element. This creates a gap in which tips 2 and 3 are located. I
    At the end of the element 7, remote from the stepped depression, a pair of annular tides 10 and II are made, the height of which is equal to the height of the shoulder of the first stepped protrusion.
    Between the ring tides and the first collar is a series of coaxial
    of another element, forming a channel in which there are 1 jaws of 2 and 3 arc extinguishing plates. Insulating partitions on the side facing the contacts are covered with refractory plates 21, 2 З.п, фл., 6 Il.
    holes 12, corresponding to coaxial holes 6 in arcing plates 1.
    In the composition of the extinguishing chamber
    Two arcing horns 13, made of extruded copper rolled products, are included. Such an arcing horn has a first bar of 14 rectangular cross-section, twisted at an angle of 90 in the section 15 between the free end 1I of the last, and a second bar 16 of rectangular cross-section longer than the first bruise juice. The second bar is twisted at 90 in section 17 near the free ends of one of the W-THx and bent at an acute angle in the area of twisting. Free end of the second bar near
    0 of the twisting section is welded to the free end of the first bar 14, so that sections 15 and 7 of the twist of each bar are opposite to each other, and the free end of the first bar 14 of the second bar is located at the free end of the second bar 16. Between section 17 of the second bar and its free end is a series of openings 18 provided with external apertures 19 on the side remote from the welded joint between the first and second bars.
    The arc-suppressing chamber contains a series of 1 curtain bars 20 made of an insulating material. Yes, the gasket is formed from a rectangular sheet in which a pair of holes are drilled in two adjacent corner sections of
    in diameter, and fitted with ring tides 10 and P on the insulating wall: x 7,
    The arc chamber also includes a pair of plates 21, made of refractory material and having a rectangular part, from the central extreme part of which a rectangular hinged part (not shown) runs.
    A pair of arcing horns 13 is inserted into a groove 22 provided with openings made in a rectangular end plate 23 made of an insulating material. When mating insulated mounting screws 24 with holes 18 in the second bar 16 of the arcing horn, the tides 19 are turned out. in contact with the open surface of the groove 22, the first bar 14 of the arcing horns protrudes beyond the end plate. The end plate 23 is provided with a series of coaxial holes 25 on either side of the groove corresponding to the holes 12 in the insulating walls 7 and the holes 6 in the arc extinguishing plates 1.
    Packing arc suppression plates 1, insulating bulkheads 7 and ventilation pads 20 continue this process further until a package containing preferably 20-200 arc suppression plates is received, with a number of ventilation pads in the ratio of 1 to 30 arc extinguishing plates. When the final bag size is reached, install the arcing horns, end plates and fix them with screws.
    Under operating conditions, the assembled arc-suppressing chamber is mounted on a circuit breaker having a pair of movable arc-initiating contacts, which enter the space between the plates 21 and s between the arc-aligned arc horns. The first bars 14 of the arcing horns are electrically connected to the movable arcing initiating contacts, and the circuit breaker is connected to the power grid by means of contacts that are attached to the electric wires, for example, to busbars.
    To induce an electric arc, a circuit breaker is applied to the supply voltage and a magnetic field is created either by the arc itself or by the coils inside the circuit breaker. The movable arches are then quickly retreated to the side, and thus the arc formed spreads along the arcing horns and enters the space between the plates 21 of the arcing chamber. This arc intersects the space between the plates 21 and does not fall on the tips 2 and 3 of the arcing plates 1 due to the presence of a series of insulating walls 7, which all together surround the tips 2 and 3 of the arrays of the extinguishing plates 1. The shape of the arcing plate 1 and the magnetic field exert such an action that the arc is drawn in toward the top of the notch-notch in each of the extinguishing plates 1. In the slot, the presence of a magnetic field is not observed, and the arc is divided into a series of arcs, known as successive arcs. Successive arcs approach the open parts of the rectangular portions of each arc suppression plate 1 and intersect the open portion of each arc suppression plate 1 to part 5 covered with insulating material.
    In succession, arcs may be maintained inside the open portion of the rectangular portions of the arcing plates 1 until the arc is extinguished. The suppression of successive arcs is achieved by establishing a sufficient arc voltage, so that the resulting arc resistance increases and causes the current to zero. The successive arcs are prevented from being ejected from the arc-suppressing chamber due to the presence of a coating on part 5 of insulating material on the arc-suppressing plates 1. The ionized gas produced during the propagation of successive arcs is vented through the gap between the upper part of the arc-suppressing plates I, and any renewal of the arc inside the clouds of ionized gas is reduced to a minimum due to the presence of ventilation pads 20 that are in the path of the gases discharged from the arcing cameras,
    Depending on the design of the circuit breaker, in particular the positioning of the arcing contacts, part of the arcing plates and associated insulating elements near the end plates of the arresting chamber may be smaller in length than the part of the insulating elements and arcing plates connected with them that occupy space near the arcing initiating contacts.
    A series of insulating elements can be made as an integral structure, thereby forming a pair of spaced apart 10 s
    insulating partitions with a series of spaced parallel channels, passing perpendicular to the section between the partitions.
    The plates can be made in one piece with insulating partitions, the latter in this case made of refractory material.
