Definitions
- the invention relates to an arc extinguishing plate package for an electrical switching device, especially for a circuit breaker and the like. According to the preamble of Claim 1.
- a circuit breaker, motor protection switch or the like Has the task of the so-called. Switch nominal load; a short-circuit current must also be switched off, in particular a circuit breaker also has the task of short-circuit current to limit the so-called prospective short-circuit current to the network charged.
- the performance can also be increased if instead of a single one Contact point two contact points are provided; the same applies to these Problem like with corresponding higher breaking capacities.
- the object of the invention is to provide a perforated arc stack for an electrical one To create switches, especially for a circuit breaker, in which the number the arc quenching plate is increased with the same package size.
- the arc quenching plates which are arranged in the package are bent over a line running in the direction of the arc, so that two are parallel form running and offset sheet metal sections; the sheets are then laid one on top of the other, an insulating layer being placed between the touching sections is, whereas the other sections of two adjacent sheets each Take the required distance between the arc extinguishers.
- An angled sheet and a flat sheet can alternate be touching side by side or on top of each other.
- the contact surfaces only adjoin a longitudinal edge of the sheets, whereas the sections that have the normal distance to the other longitudinal edge connect; there is also the possibility that the contact surfaces alternate border on opposite longitudinal edges.
- a further embodiment of the invention can go so that all sheets are bent are and, and that the bend line of all bent sheets in the middle of the Package or off-center.
- the insulation can be achieved by insulating the individual sheets in the contact areas be educated; there is also the possibility that the insulation is through Webs is formed in the housing of the switching device receiving the package. In this In this case, the sheets are guided directly in the housing.
- Fig. 1 shows a view of a circuit breaker 10, which is in a housing 11 a switch lock 12, an electromagnetic trigger 13, a thermal Trigger 14, a movable switching lever 15 and a fixed contact piece 16th having.
- the fixed contact piece 16 is a first arc guide rail 17 and the movable contact piece 15a arranged on the switching lever 15 has a second one Arc guide rail 18 associated with one of several arc quenching plates Take existing arc extinguishing package 19 between them.
- the distance between the individual Extinguishing sheets do not fall below a certain value, otherwise the arc extinguishing ability is disturbed.
- Fig. 2 shows a first embodiment of such angled arc quenching plates.
- the arc quenching package described here alternately has a smooth, planar quenching plate 20, to which a cranked quenching plate 21 connects; on this closes a smooth quenching plate 22 and a cranked one Extinguishing plate 23, etc. 2, the quenching plate 21, 23 ... bent in the middle, along a bend line, in the direction of the arc runs.
- two sections 25, 26 are formed, which are parallel to each other, the one surface 27 of the one section 25 in the same
- the plane lies like the opposite surface 28 of the other section.
- the flat quenching plate 20 bears directly on the section 26 and on the section 25 puts on the next flat sheet 22, etc.
- each arc blanket 36, 37 ... is in its Center line bent, being on the opposite outer surfaces of the Quenching plate package are two flat quenching plates 38 and 39; these quenching sheets can also be formed by the arc guide rails 17, 18.
- the configuration according to FIG. 4 is similar to the arrangement according to FIG. 2. Only located the contact surfaces of two bent plates 50, 51 with the one in between flat sheet 52 located on one side, whereas the corresponding sections of the bent plates 51, 53, which is the fire-extinguishing plate located between them touch, on the other side of the crank line 55.
- the thus formed Pairs of contact surfaces are alternately to the left and right of the crank line.
- the insulating layer 29, 30, 31 etc. can be coated by coating the corresponding sections of the arc quenching plates.
- Housing 11 of the circuit protection switch 10 corresponding wall projections are provided are between which the individual arc quenching plates are guided.
- own package housing which in principle in the same way as the area of the housing 10 of the circuit breaker which receives the extinguishing plates is trained to create that the individual arc quenching plates in the 2 to 4 shown in relation to each other.
- the invention is illustrated using three exemplary embodiments. It goes without saying that variations of these arrangements are within the scope of the invention fall; it is assumed that the individual arc quenching plates in certain Areas are placed directly on top of each other with the interposition of insulation, whereas they are suitable for guiding and extinguishing an arc in other areas Distance. 2 to 4 is the offset line arranged in the center, there is of course also the possibility of the crank line one of the cranked quenching sheet pact closer to the one longitudinal edge and the of the following quenching plate closer to the other longitudinal edge of the quenching plate package to lay so that almost two bend lines or planes are formed and the gaps, in which the arc is located, overlap the center line.
- cranking level is understood to mean that level which is above that of one another Bend lines is stretched. In the embodiments according to FIGS. 2 to 4 is only a cranking plane is present; if there are two cranking levels, take it a distance between them that does not hinder a good deletion.
