Definitions

the invention relates to an arc extinguishing device according to the preamble of claim 1.
a known arc quenching device of this type is located together with an associated switch in a closed space filled with an electronegative quenching gas.
the quenching plates assembled into a package are arranged one behind the other in the direction of movement of an arc-pulling switching piece of the switch in the event of a shutdown and offset in the longitudinal direction so that the distance between the arc-pulling end of the switching piece and the facing edges of the quenching plates in the course of Switch-off movement increases.
a disadvantage of this arrangement is that due to the staggered arrangement of the quenching plates, the quenching plate stack is basically arranged in a diamond-shaped manner and is thus extended in the diagonal direction.
the invention has for its object to take measures in an arc extinguishing device according to the preamble of claim 1, by means of which a substantial improvement of the arc extinguishing effect is achieved with simple means in a compact construction.
an arc extinguishing device with perforated quenching plates, which are preferably made of expanded metal
the quenching plates can be used in a cuboid arrangement and thus in the usual compact embodiment. In switching tests in the medium-voltage range at 24 kV, the cut-off power was increased from approximately 200 amperes to approximately 700 amperes in the case of a cuboidal fire-extinguishing plate arrangement.
a medium-voltage switch-disconnector 1 In a room (not shown) filled with an electronegative extinguishing gas, in particular sulfur hexafluoride (SF6), there is a medium-voltage switch-disconnector 1, the movable contact piece 1.1 of which is pivotally supported at one end about an axis 2 and whose switching piece end 1.2 is connected when an load current is switched off closed switching path with a fixed contact 1.3 is in an electrically conductive slide system.
the contact piece 1 To open the switching path 1.2, 1.3, the contact piece 1 is pivoted away from the fixed contact 1.3 by means of a drive rod 3 which is articulated thereon, the free contact piece end 1.2 leaves the fixed contact piece 1.3 on an arc horn 1.4 provided thereon.
SF6 sulfur hexafluoride
the contact piece 1.1 In the direction of movement of the contact piece 1.1, adjacent to the arcing horn 1.4, there is a quenching plate packet 4 with individual quenching plates 5, which are arranged parallel to one another at a distance as a cuboid block.
the quenching plates 5 lie one behind the other in the direction of movement of the switching element 1.1.
the arc-pulling free contact piece end 1.2 only approaches the extinguishing plate edges located there after a predetermined swivel angle to a minimum distance a and moves away from the adjacent extinguishing plate edges during further swiveling.
the longitudinal axis 1.5 of the movable contact piece 1.1 runs at the point of greatest proximity to the quenching plates 5 in a plane to which the quenching plates 5 lie in parallel planes.
At least one of the quenching plates 5, but preferably all of them, are provided with a plurality of openings 6, which in particular are regularly distributed over the surface, as shown in FIG. 2.
These quenching plates 5 are preferably made of expanded metal with diamond-shaped openings 6, the webs 7 surrounding the openings 6 being inclined with respect to the plane of the quenching plate.
the center distance between adjacent quenching plates 5 is approximately 1/10 of the greatest edge length of the quenching plate 5 and is preferably approximately 7 mm.
the extinguishing plates 5 can optionally have at their edge facing the contact 1.1 a cutout open towards the contact end 1.2, the width of which can be greater than the width of the free contact end 1.2.
the contact piece 1.1 is preferably designed as a switch blade which is rotatably mounted at one end and which contacts the fixed contact piece 1.3 on opposite sides in order to achieve an optimal current transfer with a low contact resistance.
the arc horn 1.4 runs in particular parallel to the adjacent first quenching plate of the quenching plate stack and is connected to it in a metallic and electrically conductive manner.
